Letter to Stockholders

The theme of last year’s 2008 annual report was “Making the Turn,”

which has several meanings. When used in the context of the explo-

ration and production industry, it literally describes the drilling

operation in a horizontal well when you begin to turn the wellbore

horizontally and extend the lateral that will expose a larger section of

pay than what you could otherwise achieve with a vertical well. In a

broader and more strategic sense, the phrase conveys a perception

that a person or entity has transitioned through challenging or diffi-

cult circumstances and that the outlook is much more promising.

Both of these meanings were applicable to St. Mary in 2009. For the

former use of the phrase, it is relevant given the Company’s focus on

resource plays, most of which are drilled using horizontal wells. The

latter use is perhaps more significant since it aptly captures the

transformation that St. Mary has been undergoing the last couple of

years and our feeling that we are now well positioned for significant

growth ahead.

At this time a year ago, the general tone regarding the economy was

one of great uncertainty. The broader debt and equity markets saw

extreme volatility as questions about the global economic environment

and the duration of the downturn weighed on the minds of investors.

Concerns about demand put pressure on natural gas and oil prices.

Exploration and production companies dropped drilling rigs as

quickly as they could amid fears over liquidity and financial position,

with some firms selling debt or equity at high costs in order to quickly

repair their balance sheets. St. Mary was well positioned as it faced

these challenges. Our balance sheet was in solid shape as we entered

2009. Our hedging positions helped provide a base level of cash flow.

We had a reasonable amount of lease term left on our strategic lease-

hold positions and also had limited long-term commitments to rigs,

so we were able to slow our activity down very quickly. We made a

decision to focus our efforts on advancing our understanding of the

emerging resource plays in our portfolio, particularly the Eagle Ford

shale, the Haynesville shale, and the Marcellus shale. The goal was

to have an improved project inventory available for when economic

conditions improved. We also made a deliberate decision to defer
investment in development projects. Our view was that service

costs would come down throughout the year and that it made more

economic sense to develop projects in that lower cost environment,

particularly in light of the weaker commodity prices that we were

2

faced with at the time.

2009 RESULTS

It is probably safe to say that the business community is happy to have

2009 behind us. Our 2009 results certainly reflect the challenging

environment that we navigated throughout the year. Following is a

summary of our 2009 results:

• Proved reserves as of December 31, 2009 were 772.2 BCFE,

a decrease of 11% year over year.

• Reported average daily production for the year was

298.8 MMCFE, a decrease of 5% year over year.

• Our net loss for the year was $(99.4) million, or $(1.59) per

diluted share.

At first glance our 2009 performance clearly looks disappointing, but

some commentary and context is necessary to have a complete view

of last year’s performance.

As noted above, proved reserves at the end of 2009 were 772.2 BCFE,

which was a decrease of 11% from the 865.5 BCFE at the end of

2008. Our year-end 2009 proved reserves reflect the new SEC reserve

rules that went into effect at the end of the year, which among other

changes required that a lagging 12-month average price rather than

an end of year price be used to estimate proved reserves. Under these

rules, the prices used to estimate our proved reserves were $3.87 per

MMBTU of gas and $61.18 per barrel of oil, which were 32% lower

and 37% higher, respectively, than the prices used for proved reserves

at the end of 2008. Had we used the previous methodology, i.e. end

of year prices, our proved reserves would have been 897 BCFE as

of December 31, 2009, which would have represented 4% proved

reserve growth from the prior year.

Our reported proved reserves for year-end 2009 were impacted by the

sale of 44 BCFE of proved reserves, the majority of which related to

our non-strategic coalbed methane project at Hanging Woman Basin.

Revisions for the year were comprised of a net 12 BCFE upward price

revision and a downward engineering revision of 62 BCFE. The

pricing revision generally reflected positive price revisions from oil

properties and negative price revisions on gas properties which are

consistent with the change in prices used to estimate proved reserves

between 2008 and 2009. The majority of the downward performance

revision relates to our Wolfberry tight oil program in the Permian

Basin and Cotton Valley properties in our ArkLaTex region. We added

110 BCFE through the drill bit, which replaced our production for

the year. Drilling additions are directly related to the amount of

capital invested in drilling activities. As I mentioned earlier, we shifted

our focus away from development drilling for much of 2009 and this

reduced our potential to add proved reserves during the year, all other

things being equal.

Our reported production for 2009 was 109 BCFE, which was a

decrease from the 115 BCFE we produced in 2008. It should be

noted however that we have been divesting of non-core properties

over the last couple of years as part of our strategic transformation to

a resource play-focused company. Adjusting for these divestitures,

5

production was flat from 2008 to 2009. Given the significant reduction

in development capital in 2009, keeping production level on these

retained properties is something that we feel good about.

Our net loss for 2009 was $(99.4) million, or $(1.59) per diluted share.

This compares to net income of $87.3 million, or $1.38 per diluted

share, in 2008. Our 2009 results were impacted most significantly

by lower commodity prices and large non-cash impairments. The

average net realized price for 2009 was $6.94 per MCFE, which is

31% lower than the $10.11 per MCFE realized in 2008. The decrease

resulted in lower oil and gas revenues for the year. The impairment

of proved properties for 2009 was $174.8 million. The majority of

this impairment related to the first quarter of 2009, when properties

in eastern Oklahoma as well as coalbed methane properties in the

Rocky Mountain region were impaired. Low natural gas prices in

effect at the end of the first quarter contributed to these impairments.

We also recognized $45.4 million for abandonments and impairments

of unproved properties in 2009 to write off acreage that the Company

does not believe it will be able to develop under current capital

allocations or given our technical assessment of the acreage.

Our 2009 results clearly do not represent the level of performance that

we strive to achieve. However, I believe that we responded appropri-

ately to the difficult circumstances we were forced to face. Moreover,

our 2009 financial information does not capture the improvement in

our portfolio or the success of our transformation efforts.

LOOKING UP!

Which brings us to our theme for this year’s annual report—“Looking

Up.” Contrasting where we stand today to where we were a year

ago, we clearly are in a better position now and have better visibility

to where we are going as a company. Today, the broader economic

environment has stabilized and the economy appears to be recovering,

albeit slowly. The debt and equity markets are accessible again and at

reasonable costs. Commodity prices have improved from the lows

seen in early 2009. While we expect there will always be some level

of volatility in oil and gas prices, prices we are seeing in the

futures markets are at levels where we have developed a rational

growth plan for the company.

Things are certainly “Looking Up” at St. Mary. The nascent resource

plays that we had in our portfolio at the beginning of last year
experienced positive developments in 2009. In the Eagle Ford shale

program in South Texas, favorable results from our early testing on

our operated leasehold led us to expand our drilling in the second half

of 2009. We have been encouraged by the consistency of the results

we are seeing in the Eagle Ford program. Additionally, the richer gas

6

and condensate that we are producing on a portion of our acreage

position provides for a more valuable product stream that enhances our

returns. In our Marcellus shale program in north central Pennsylvania,

we drilled and completed two horizontal wells in 2009. The initial

tests from these two wells lead us to believe that we will be able to

pursue a commercial development program on much of our Marcellus

shale acreage. In the Haynesville shale, industry activity around our

leasehold in Shelby and San Augustine Counties, Texas appears to

confirm that some level of development of the Haynesville will take

place in East Texas. This is in contrast to the view of many a year ago

that acreage outside of North Louisiana would not be economic to

develop for the Haynesville shale. In addition to these three plays, the

application of horizontal drilling in the Granite Wash in the Anadarko

Basin and a better understanding of the Bakken and Three Forks

intervals in the Williston Basin have further improved our inventory.

This improvement in inventory is only valuable to our stockholders

if we have the financial capability to develop it, and I am pleased to

report St. Mary has the liquidity and financial strength to do just that.

We successfully managed our capital investments in 2009 to be within

our cash flows for the year and not only preserved our strong balance

sheet but strengthened it by yearend. By divesting over $300 million

of non-core properties in late 2009 and early 2010, most of which

were in the Rocky Mountain region, not only did we improve our

operational focus but we also raised cash that can be used to test and

develop our emerging resource plays and further strengthen our

financial position.

Our plan for 2010 is to continue advancing our emerging resource

plays. We have active operated programs budgeted in the Eagle Ford

and Haynesville shales. In the Marcellus shale, we have a number of

horizontal wells planned to further test our acreage as well as a seismic

shoot to acquire 3D data over our leasehold. We will also be focusing

development capital toward oilier parts of our portfolio, which means

increased activity in the Permian and Williston Basins, with better

margins due to higher crude prices.

With the broader economy recovering and our project portfolio

and financial capabilities improved over last year, things are clearly

“Looking Up” for St. Mary!

ITEMS 1. and 2.  BUSINESS and PROPERTIES 

General 

We are an independent oil and gas company engaged in the exploration, exploitation, development, 

acquisition, and production of natural gas and crude oil in North America.  We were founded in 1908 and 
incorporated in Delaware in 1915.  Our initial public offering of common stock took place in December 1992.  
The common stock of the Company trades on the New York Stock Exchange under the ticker ―SM.‖ 

Our principal offices are located at 1776 Lincoln Street, Suite 700, Denver, Colorado 80203, and our 

telephone number is (303) 861-8140. 

Strategy 

Our mission is to deliver outstanding net asset value per share growth to our investors via attractive oil 

and gas investments.  Historically, a key part of meeting the goal of building stockholder value was the successful 
execution and integration of niche acquisitions at attractive costs.  Recently we shifted the emphasis of our efforts 
to focus on the exploration for and development of onshore resource plays in North America.  This shift was due 
to the fact that, as we grew, the universe of potential niche acquisition targets became smaller and less impactful 
to our growth.  Additionally, we believe that we will be able to create more long-term value for our stockholders 
by building an asset base that allows for more predictable growth in production and reserves and does not rely 
solely on acquisitions.  Our strategy is based on the following points: 

  Acquire significant leasehold positions in new and emerging resource plays 

  Leverage our core competencies in drilling and completions, as well as acquisitions 

  Exploit our legacy assets and optimize our asset base through divestitures of non-core assets when 

appropriate 

  Maintain a strong balance sheet while funding the growth of the enterprise. 

Significant Developments in 2009 

  Broad Economic Downturn.  Beginning in the latter part of 2008 and continuing into the first half of 
2009 the global economy experienced a significant downturn related primarily to concerns over the 
U.S. financial system.  The impact of the downturn spread quickly and affected a wide range of 
industries.  There were two significant ramifications to the exploration and production industry.  The 
first was that capital markets were essentially frozen at the beginning of 2009.  Equity, debt, and 
credit markets were shut down.  We were able to weather this initial shock as a result of our strong 
liquidity position and relatively limited capital commitments.  The second impact to the industry was 
that fear of global recession and the associated negative impact on energy demand resulted in a 
significant decline in oil and gas prices.  We significantly scaled back our operating activity in 
response to these price decreases.  Our hedging program helped moderate the price fluctuations that 
we experienced, particularly in the first half of 2009.  After the first quarter of 2009, the broader 
economy began to stabilize.  The public markets for debt and equity opened up and banks began to be 

1 

 
less restrictive with credit.  We were able to renew our credit facility in April of 2009.  The outlook 
for commodity prices also began to improve.  The rapid decrease in activity across the exploration 
and production industry led many oilfield service companies to cut their prices to the benefit of 
ourselves and our peers as the year progressed.  As industry conditions improved throughout the year, 
drilling activity increased in many parts of the country. 

  Advancement of Resource Play Potential.  From late 2007 through 2009, we established meaningful 
positions in several new potential resource plays, principally the Eagle Ford shale, Haynesville shale, 
and the Marcellus shale.  Over the past year we worked to advance our understanding of these plays 
and move them closer to development mode.  The greatest progress was made in our Eagle Ford shale 
program in South Texas.  We successfully tested seven wells across our operated acreage position 
during the second half of 2009.  The early results from this program suggest wells at the southern end 
of our acreage will produce drier gas while wells drilled further north will produce higher BTU-
content gas and condensate.  We are currently booking only the parallel offsets to producing wells as 
proved undeveloped locations.  As a result, meaningful potential exists to grow proved reserves on 
our operated acreage because of our planned drilling activity for 2010.  On our joint venture acreage 
in Dimmitt County, Texas, we believe these wells will produce even higher amounts of condensate 
and oil compared to our operated position.  In the Haynesville shale program in the ArkLaTex region, 
a number of successful wells were drilled around our acreage position in Shelby and San Augustine 
counties in East Texas in 2009.  The 3D seismic shoot of our acreage was recently received, and we 
have begun our horizontal drilling in the play.  In our Marcellus shale program in north central 
Pennsylvania, we drilled and completed our first two horizontal wells during 2009.  Initial indications 
from the well tests were encouraging.  We are in the process of constructing the gathering system that 
will connect these two wells, as well as future wells, to the sales pipeline. 

  Volatility in Commodity Prices.  Prices in 2009 were generally more stable than in 2008.  However 

the exploration and production sector still experienced significant volatility in the prices for crude oil 
and natural gas.  Our operations and financial condition are significantly impacted by these prices.  
The spot price for NYMEX crude oil in 2009 ranged from a high of $81.04 per barrel in October to a 
low of $33.98 per barrel in February.  The average spot price for oil during the year was $61.99 per 
barrel.  The volatility in crude oil prices in early 2009 was driven by concern regarding global 
demand for oil.  A volatile U.S. dollar was also a contributing factor in crude price volatility as the 
spot price of oil reacted to the relative weakening or strengthening of the U.S. dollar. 

The spot price for gas at Henry Hub, a widely used industry measuring point, averaged $3.94 per 
MMBtu in 2009, with a high of $6.11 per MMBtu in January and a low of $1.88 per MMBtu in 
September.  Natural gas prices came under pressure in 2009 as a result of lower domestic product 
demand caused by the weakening economy; and concerns over excess supply of natural gas due to the 
high productivity of several emerging shale plays in the U.S.  Some of the regional markets where we 
sell gas have seen increased downward pressures on price as a result of high levels of activity in the 
regions, as well as a lack of pipeline takeaway capacity or local demand.  This was most pronounced 
in our Mid-Continent and Rocky Mountain regions.  However, local index differentials, in the areas 
where we sell gas, narrowed towards NYMEX Hub prices in late 2009. 

  Decrease in Year-End Proved Reserve Estimates.  Our estimated proved reserves decreased 11 

percent to 772.2 BCFE at December 31, 2009, from 865.5 BCFE at December 31, 2008.  We added 
109.6 BCFE from our drilling program during the year, with our emerging resource play in the Eagle 
Ford shale in the Maverick Basin in South Texas contributing a significant portion of those additions.  
Our programs targeting the Woodford shale in eastern Oklahoma and the Bakken/Three Forks 
formations in the North Dakota portion of the Williston Basin also added meaningful additions in 
2009.  We sold 44.2 BCFE of proved reserves during the year, with roughly 90 percent of those 
relating to the divestiture of our coalbed methane project at Hanging Woman Basin along the border 
of Montana and Wyoming.  The balance of the divested properties sold in 2009 related to non-
strategic assets spread across our company. 

2 

 
We had a net downward revision of 49.6 BCFE that consisted of 61.6 BCFE in downward 
engineering revisions and an upward pricing revision of 12.0 BCFE.  The largest portion of the 
performance revision relates to producing properties in our Wolfberry tight oil program in the 
Permian Basin in West Texas.  Well performance data collected during 2009 at our Sweetie Peck and 
Halff East programs that target the Wolfberry interval indicate that these assets are underperforming 
our year-end 2008 decline forecasts.  Accordingly, we removed 37 BCFE from proved reserves in the 
Permian region, primarily related to the Wolfberry tight oil program.  We believe a significant portion 
of these reserves, while not meeting the criteria to be booked as proved reserves at year-end, are 
likely to eventually be produced.  We also had a downward performance revision of approximately 12 
BCFE related to certain Cotton Valley assets in our ArkLaTex region.  The pricing methodology used 
to determine proved reserves changed in 2009 in accordance with new rules promulgated by the SEC.  
Rather than using year-end pricing, companies are now required to use the 12-month average of the 
first of month prices for oil and gas to estimate proved reserves.  This change in methodology from 
2008 resulted in a higher oil price and a lower gas price in effect for determining year-end proved 
reserves for 2009.  As a result, we recognized positive pricing revisions in our oil-weighted Rocky 
Mountain and Permian regions that offset the negative price revisions we recognized in the natural 
gas weighted Mid-Continent, ArkLaTex, and South Texas & Gulf Coast regions.  Under the previous 
methodology of using year-end pricing for the determination of proved reserves, we would have had a 
four percent increase in proved reserves to approximately 897 BCFE. 

Prior to and subsequent to year-end, we entered into several transactions to divest non-strategic 
properties across our company.  Proved reserves associated with these properties are estimated to be 
approximately 71 BCFE and primarily relate to the previously announced Rocky Mountain oil 
property divestiture.  Part of this divestiture package closed in mid-February 2010 and we expect the 
balance to close by the end of the first quarter of 2010. 

 Impairment of Proved Properties.  We recognized pre-tax non-cash impairments of proved properties 
in the amount of $174.8 million in 2009 compared with $302.2 million of proved property 
impairments in 2008.  A significant decrease in commodity prices, including differentials, during the 
first quarter of 2009 caused the majority of the non-cash impairment.  The largest portion of the 
impairment in 2009 was $97.3 million related to assets located in the Mid-Continent region which 
were significantly impacted by both low natural gas prices and wider than normal differentials at the 
end of the first quarter.  The ArkLaTex region was impacted by a $20.4 million impairment related to 
downward pricing and engineering revisions.  We incurred a $14.0 million impairment of proved 
properties related to the write-down of certain assets located in the Gulf of Mexico for which we are 
relinquishing our ownership interests to satisfy our abandonment obligations. 

  Abandonment and Impairment of Unproved Properties.  During the year, we abandoned or impaired 

$45.4 million related to unproved properties.  The largest specific components of the 2009 
impairment and abandonment related to the Floyd Shale acreage located in Mississippi and acreage in 
Oklahoma.  The remaining write-offs were related to acreage we believe we will not keep based on 
our current capital allocation plans or related to acreage that we do not believe will be prospective. 

  Divestiture of Non-Strategic Properties.  In 2009 we undertook an effort to sell a number of non-

strategic properties in order to optimize our portfolio.  The objective of these divestitures is to dispose 
of properties with limited future drilling potential while generating cash that can be used in the testing 
and development of our resource plays.  During 2009 we sold roughly 44.2 BCFE of reserves, the 
vast majority of which related to our coalbed methane program in Hanging Woman Basin.  We 
received $39.9 million in proceeds from the sales we closed in 2009.  Subsequent to year end, we 
closed on a portion of our previously disclosed sale of non-strategic oil and gas properties in the 
Rocky Mountain region.  The Wyoming sub-package was sold to Legacy Reserves Operating LP.  
The cash received at closing was $118.7 million before commission costs. The final sales price is 
subject to normal post-closing adjustments and is expected to be finalized by the end of second 
quarter of 2010.  Additionally, subsequent to year-end, we also entered into agreements to sell the 

3 

 
 
remaining non-core properties from our Rocky Mountain divestiture package in North Dakota for 
$137 million to Sequel Energy Partners LP, as well as some other minor properties for approximately 
$6 million.  We expect these divestitures to close by the end of the first quarter of 2010.  In total, 
these divestitures represent 71 BCFE of proved reserves. 

Outlook for 2010 

The general economic outlook for the country has improved compared to this time a year ago.  We 
successfully weathered a rough 2009, and in the process advanced a number of potential resource plays and 
improved our financial condition. 

As we enter 2010, our company is well positioned both financially and operationally.  Early in 2009, we 

extended the maturity of our revolving credit facility and subsequently reduced outstanding borrowings on that 
facility during the year.  As of February 16, 2010, we had $467 million available to us under the revolving credit 
facility.  We have no debt maturities until 2012.  Additionally, we believe that access to the capital markets has 
improved significantly since last year and that we could access capital through the public markets, if necessary.  
From an operational standpoint, we believe 2010 has the potential to be very promising for our company.  We will 
be building upon our successful testing programs from 2009.  We have moved the Eagle Ford shale program 
closer to development mode, and it will receive the largest portion of our capital budget this year.  We will also be 
allocating more capital toward oil and rich natural gas projects, given their higher returns in the current 
environment.  Specifically, we will be drilling more Wolfberry tight oil and Bakken/Three Forks wells in the 
Permian and Rocky Mountain regions, respectively.  In the Haynesville shale, we have begun our horizontal 
drilling program.  We continue to monitor service costs as the recent uptick in industry activity may pressure rates 
for the drilling and completion of wells higher than the levels we saw in 2009.  We intend to fund these projects 
with our current year operating cash flows and proceeds from our previously announced non-core divestitures. 

Assets 

As of December 31, 2009, we had estimated proved reserves of 53.8 MMBbl of oil and 449.5 Bcf of 

natural gas.  The 12-month average prices in effect on December 31, 2009, used to estimate proved reserves were 
$61.18 per barrel of oil and $3.87 per MMBtu of gas, which represent a 37 percent increase and 32 percent 
decrease, respectively, from prices used to estimate proved reserves as of December 31, 2008.  On an equivalent 
basis, our proved reserves were 772.2 BCFE as of December 31, 2009, a decrease of 11 percent from 865.5 BCFE 
at the end of the prior year.  On an equivalent basis, 82 percent of our proved reserves were classified as proved 
developed as of year-end.  Total proved oil and gas reserves had a PV-10 value of $1.3 billion and a standardized 
measure value of $1.0 billion including the effect of income taxes.  A reconciliation between these two amounts is 
shown under the Reserves section in Part I, Items 1 and 2 of this report.  During 2009 our average daily 
production was 194.8 MMcf of gas and 17.3 MBbl of oil, for an average equivalent production rate of 
298.8 MMCFE per day, which was down slightly compared with 313.1 MMCFE per day for 2008.  Adjusting for 
production from properties sold as part of our active divestiture efforts over the last two years, production from 
retained properties has remained essentially flat from 285.6 MMCFE per day in 2008 to 284.7 MMCFE per day in 
2009. 

In 2009 we incurred costs of $419.0 million for drilling and exploration activities and acquisitions.  This 

was 51 percent lower than the $857.7 million incurred in 2008.  During 2009 we incurred exploration costs of 
$154.1 million compared to $92.2 million in 2008.  We incurred development costs of $223.1 million in 2009, 
which was 62 percent lower than the $587.6 million in 2008.  The decrease in development dollars and increase in 
exploration dollars reflects our decision to not invest capital in development projects in a low commodity price 
environment, particularly while service costs were declining.  Moreover we ramped up our exploration efforts to 
accelerate our understanding of our emerging resource plays, particularly in the Eagle Ford shale, in order to put 
ourselves in a positive position once industry conditions improved.  In 2009 we invested a total of $41.7 million 
on undeveloped leasehold compared to $83.1 million in 2008.  The majority of our 2009 leasing activity targeted 
emerging resource plays in our South Texas & Gulf Coast and Mid-Continent regions.  We spent approximately 
$126.4 million in 2008 on undeveloped leasehold, including leasehold acquired as part of producing property 

4 

 
acquisitions, targeting the Cotton Valley and Bakken formations in the ArkLaTex and Rocky Mountain regions, 
respectively.  In 2009, we did not make any meaningful acquisitions. 

Our operations are currently concentrated in five core operating areas in the United States.  The following 

table summarizes the production, proved reserves, and PV-10 value of our core operating areas as of 
December 31, 2009.

ArkLaTex Region.  St. Mary’s operations in the ArkLaTex region are managed from our office in 

Shreveport, Louisiana.  The ArkLaTex region was our first operating office, originating from an acquisition in 
1992.  For years the activities of this region focused on the Cotton Valley, James Lime, and Travis Peak 
formations in the region.  In 2008 the Haynesville shale emerged as the leading potential resource play in East 
Texas and North Louisiana. 

The ArkLaTex region incurred costs of $65.7 million in 2009 for exploration, development, and 

acquisition activities.  This amount is 70 percent lower than the $218.4 million spent in 2008, which included 
$60.3 million in acquisitions targeting the Cotton Valley formation in East Texas.  Significantly less money was 
spent on development and exploration activity in 2009 compared to 2008.  With the emergence of the Haynesville 
shale late in 2008 and into 2009, our operating partner activity targeting the Cotton Valley and James Lime 
formations declined significantly as they focused on testing and developing their Haynesville shale properties.  
We participated in a number of partner-operated wells that focused on the Haynesville shale.  Additionally, we 
elected to defer most of our operated horizontal Haynesville drilling until we could acquire seismic data that 
would help mitigate risk for larger parts of our acreage.  Our 2009 operated activity in the ArkLaTex region was 
primarily focused on drilling wells that preserve acreage.  The region’s 2009 production decreased 19 percent to 
14.9 BCFE as a result of the lower levels of activity described above.  Our 2009 year-end proved reserves were 
120.0 BCFE, which is 29 percent lower than the 2008 year-end proved reserves of 170.0 BCFE.  The decrease in

proved reserves is primarily the result of 14.9 BCFE of production and 48.0 BCFE of negative pricing and 
engineering revisions.  At year-end 2009 we have no proved reserves booked for our Haynesville potential related 
to our acreage in Shelby and San Augustine Counties in East Texas. 

The Elm Grove Field is the highest value field in the ArkLaTex region at year-end 2009.  We own 

interests in approximately 500 producing wells in the field and believe many of those wells have future uphole 
recompletion potential.  Our working interest in the field is as high as 36 percent, although it varies greatly across 
the field.  Generally, our working interest increases as one moves south in the field.  The primary zones of interest 
in this field have historically been the Cotton Valley and Hosston.  The vast majority of the value and proved 
reserves in this field relate to those zones.  Over the past year, our operating partner has focused its drilling efforts 
almost exclusively in the Haynesville shale on acreage in the field where we have no working interest.  As a 
result, we have very little PV-10 value or proved reserve volumes attributable to the Haynesville shale at the end 
of 2009 at Elm Grove field. 

Our plans for 2010 in the ArkLaTex region are based almost entirely on testing and developing the 
Haynesville shale on our operated acreage.  We have approximately 41,000 net acres across the region with 
potential for the Haynesville shale, of which 31,000 is located in Shelby and San Augustine Counties in East 
Texas.  Roughly 70 percent of our Haynesville spending will be operated by us and will be focused on our 
acreage in these counties.  We plan to drill seven horizontal wells targeting the Haynesville shale in 2010.  We 
will also participate in a number of wells with operating partners in both northern Louisiana and East Texas that 
target the Haynesville interval.  We expect that we will invest a minimal amount of capital this year on the drilling 
of James Lime and Cotton Valley wells, although we will have some leasehold and seismic expenditures related 
to those programs in 2010.  In recent months, the industry has begun to test the Bossier shale, which is above the 
Haynesville shale.  As information emerges about this interval, we could choose to test this formation in 2010.  
We believe a large portion of our acreage position in East Texas is also prospective for the Bossier shale. 

Mid-Continent Region.  St. Mary has been active in the Mid-Continent region since 1973.  Operations for 
the region are managed by our office in Tulsa, Oklahoma.  We have been active in the Anadarko Basin of western 
Oklahoma since our entry into the region.  In recent years we have begun operating in the Arkoma Basin in 
eastern Oklahoma where the current focus is on horizontal development of the Woodford shale.  The Mid-
Continent region also oversees our Marcellus shale activity in north central Pennsylvania. 

In 2009 we incurred costs of $106.8 million in the Mid-Continent region for exploration, development, 

and acquisition activity, which is 34 percent less than the $162.0 million deployed in 2008.  Approximately 
$97 million was deployed in exploration and development activities in 2009, with the remainder being spent on 
leasing activities.  The 2009 activity for the region focused on the continued development of our horizontal 
Woodford shale program in the Arkoma Basin and included the successful completion of two pilot programs to 
test the effect of near simultaneous fracture stimulation on increased density drilling.  In the Anadarko Basin, we 
maintained a consistent level of operated activity targeting the Deep Springer formation throughout the year.  We 
also participated in a largely non-operated program targeting the stacked washes in western Oklahoma.  Lastly, 
we drilled and completed our first initial tests in our Marcellus shale program during the second half of 2009.  
Mid-Continent production in 2009 was 36.0 BCFE, an increase of 9 percent from the 33.0 BCFE produced in 
2008.  Proved reserves at the end of 2009 were 223.5 BCFE, a decrease of five percent from the 234.4 BCFE 
report for the prior year.  The decrease in proved reserves was due in large part to the low gas price in effect at 
year end which resulted in downward pricing revisions of roughly 17 BCFE for some previously booked proved 
reserves.  The low gas price also resulted in no new proved undeveloped reserves being added in the region at 
December 31, 2009. 

The Centrahoma Field in the Arkoma Basin is the highest value field in the Mid-Continent region.  At 

year-end, we have nearly 160 producing wells in the field.  Over half of those wells were completed in the 
Woodford shale and the majority of those were drilled horizontally.  The Woodford shale is the primary 
contributor to proved reserve volumes and PV-10 value at the Centrahoma Field.  We believe there is additional 
drilling potential in the Woodford shale as well as uphole development in the Cromwell and Wapanucka 
formations.

The largest operated portion of the Mid-Continent region’s budget for 2010 relates to our emerging 
program targeting the Marcellus shale in north central Pennsylvania.  We currently have roughly 42,000 net acres 
leased or optioned in the Marcellus shale.  Four operated horizontal wells are planned for the year and we expect 
to begin drilling late in the second quarter of 2010.  Additionally, we are currently in the process of constructing a 
gathering system through a large portion of our acreage position that will connect the first two wells we drilled in 
2009 to sales as well as service future development.  Our Marcellus program for 2010 also includes amounts for 
leasehold, facilities, and seismic costs.  In the horizontal Woodford, our program for 2010 is primarily designed to 
preserve core acreage.  Six operated horizontal wells are currently planned, and we will participate in a handful of 
wells that will be operated by others.  In the Anadarko Basin, we have four wells planned in the successful Deep 
Springer program our regional team has run for the past several years.  Four operated horizontal wells are planned 
for the horizontal Granite Wash play that is emerging in western Oklahoma.  Our first horizontal Granite Wash 
well in this part of the play commenced drilling in December of 2009 and is still drilling as of the date of this 
report. 

South Texas & Gulf Coast Region.  St. Mary’s presence in south Louisiana dates to the early 1900s 

when our founders acquired our namesake property in St. Mary Parish, Louisiana abutting the Gulf of Mexico.  
These 24,914 acres of fee land yielded $3.6 million of oil and gas royalty revenue in 2009.  Our presence 
expanded along the Gulf Coast as a result of the acquisition of King Ranch Energy, Inc. in 1999.  In 2007, we 
made two acquisitions in the Maverick Basin in South Texas that targeted Olmos shallow gas assets in South 
Texas and provided an entry into this multi-pay basin.  During 2009, one of the other zones of interest, the Eagle 
Ford shale, was successfully tested by St. Mary and a competitor.  Today, the Eagle Ford shale is one of the most 
promising shale plays in North America.  The focus of our Houston office has steadily shifted over the last couple 
of years away from projects along the Gulf Coast and in the Gulf of Mexico toward programs onshore that allow 
for multiple years of drilling inventory. 

Our capital expenditures for exploration, development, and acquisition activity in the South Texas & Gulf 

Coast region decreased slightly from $120.9 million in 2008 to $115.1 million in 2009.  Nearly all of the capital 
deployed in the South Texas & Gulf Coast region in 2009 targeted formations in south western Texas, namely the 
Eagle Ford and Pearsall shales.  We worked early in the year to increase our leasehold position in the area.  
Additionally, we continued to participate in a joint venture that allowed us to earn acreage by carrying a partner 
through completion in a series of wells.  In mid-2009, we began operating on acreage where we had very high 
working interests, in many cases a 100 percent.  The encouraging results from our earlier tests led to an increase 
in the number of wells drilled for 2009.  To date, the results on our operated acreage have been very encouraging.  
On large parts of our acreage, we have seen rich-gas and condensate in the production stream which enhances the 
economics of these gas wells.  We did not make any meaningful investments in properties along the Gulf Coast or 
in the Gulf of Mexico during the year.  Our last operated platform in the Gulf of Mexico was largely remediated 
and abandoned in 2009 after being damaged by Hurricane Ike in 2008. 

Production for the South Texas & Gulf Coast region in 2009 was 9.7 BCFE, a decrease of 32 percent 

from the 14.3 BCFE produced in 2008.  The largest contributor to the decline year over year was the result of our 
sale of our interest in the Judge Digby Field in southern Louisiana at the end of 2008.  Excluding the impact of 
this divestiture, production declined approximately one percent year over year.  Proved reserves at the end of 
2009 were 53.2 BCFE, an increase of 21 percent from the 43.8 BCFE reported in the prior year.  The increase in 
proved reserves reflects drilling additions of 39.0 BCFE related entirely to our program in the Eagle Ford shale 
and were offset by downward price revisions related to our Olmos gas program.  On our operated acreage 
targeting the Eagle Ford shale, we had seven proved developed wells which were producing at year-end.  This 
program is at an early stage of its development and accordingly at December 31, 2009, we are booking only 
parallel offset locations to our producing wells as proved undeveloped locations.  The result is a total of 14 proved 
undeveloped locations being booked as of year-end at a total of 24.6 BCFE.  Our operated Eagle Ford program is 
the most significant asset in the South Texas & Gulf Coast region.  

Our plans for 2010 in the South Texas & Gulf Coast region are focused exclusively on the Eagle Ford 
shale.  As of year-end, we have 250,000 net acres leased or optioned, which is an increase from our previously 
reported total of 225,000 net acres.  We operate roughly 168,000 of those net acres, most of which is at 100 
percent working interest, with the balance of the acreage being located on joint venture acreage with an industry 
7 

 
partner.  We plan to drill 34 horizontal wells on our operated acreage in 2010.  Part of our drilling program will be 
aimed at further delineating the play in order to make infrastructure commitments later this year.  We currently 
are able to market all of our production and expect to do so in the future by working with midstream partners to 
ensure we have adequate takeaway and processing capacity to meet our needs.  We will also be conducting a 
series of tests to help determine the ultimate spacing for the reservoir.  Our operating partner plans to operate two 
to three rigs during 2010 on our joint venture acreage where we have a net working interest of 25 percent. 

Permian Basin Region.  The Permian Basin area covers a significant portion of western Texas and 

eastern New Mexico and is one of the major producing basins in the United States.  Our holdings in the Permian 
Basin began with a series of property acquisitions in 1996.  In December 2006 we made a major acquisition of oil 
properties that targeted the Wolfberry tight oil play.  To manage the significant increase in operated properties 
associated with the Sweetie Peck acquisition, we opened a regional office in Midland, Texas in February 2007. 

We incurred costs of $76.5 million in the region in 2009 compared to $163.2 million in 2008.  This 

decrease in capital investment reflects the significant slowdown in our drilling activity during the first half of the 
year in response to the low oil prices being realized late in 2008 and early in 2009.  The majority of this capital 
was deployed to develop projects in the Wolfberry tight oil play, which targets the stacked carbonate Wolfcamp 
and Spraberry formations found in the basin.  We also tested other exploration concepts in the Permian during the 
year.  Production in the region increased 9 percent over the prior year, from 13.8 BCFE in 2008 to 15.1 BCFE in 
2009.  Proved reserves as of the end of 2009 were 115.2 BCFE, which is a decrease of 26 percent from 2008 year-
end reserves of 155.9 BCFE.  The decrease in our estimate of proved reserves relate to engineering revisions on 
proved producing properties in our Wolfberry tight oil program.  Well performance data collected during 2009 
from our Sweetie Peck and Halff East assets which target the Wolfberry indicate that these assets are 
underperforming our year-end 2008 decline forecasts.  Accordingly, we have removed 37 BCFE from proved 
reserves in the Permian region, primarily related to the Wolfberry tight oil program.  We believe that a significant 
portion of these reserves, while not meeting the criteria to be booked as proved reserves at year-end, are likely to 
eventually be produced. 

As of the end of December 2009, the Sweetie Peck assets in the Permian Basin collectively were the 
highest value entity in the region.  Sweetie Peck field had 182 producing wells at year-end.  We have slightly over 
20 proved undeveloped locations booked at Sweetie Peck at year-end.  We also believe there are a meaningful 
number of unbooked future drilling locations that we will be able to pursue in future years. 

The largest drilling program planned for the Permian region in 2010 is in our Sweetie Peck tight oil assets 

where we plan to drill 32 operated wells this year.  Most of the development will take place on 80- and 40-acre 
spaced locations.  Despite the downward Wolfberry engineering revisions in our proved reserve estimates referred 
to above, these projects continue to meet our economic standards for drilling, albeit at lower proved reserve 
volumes.  We will also continue to work on an exploratory program that began in 2009 and we plan to conduct a 
modest drilling program in 2010, primarily using vertical wells. 

Rocky Mountain Region.  St. Mary has conducted operations in the Williston Basin in eastern Montana 

and western North Dakota since 1991.  The region is managed by our office in Billings, Montana.  In recent years, 
we have expanded our operations into the Greater Green River, Powder River, Big Horn, and Wind River basins 
of Wyoming through a series of acquisitions.  The largest growth in the region came in late 2001 and early 2003 
with significant property acquisitions from Choctaw, Burlington Resources, and Flying J.  In recent years, we 
have been divesting of non-core properties in the Rocky Mountain region in an effort to focus our human and 
investment capital on the most impactful plays in that region. 

We incurred costs of $51.2 million in 2009 for exploration, development, and acquisitions in the Rocky 
Mountain region, compared to $190.3 million in 2008.  Our 2009 budget in the Rocky Mountain region reflected 
the low oil prices and the wide price differentials we experienced at the end of 2008.  For much of 2009, we did 
not have any operated rigs running in the region.  Our capital investments were primarily focused on the Bakken 
and Three Forks formations and were heavily weighted toward the back half of the year.  Proved reserves for the 
Rocky Mountain region were 260.3 BCFE at year-end compared with 261.4 BCFE as of the end of 2008.  The 
slight decrease in proved reserves is the result of selling 40.3 BCFE of proved reserves in the region during the 

8 

 
year, most of which related to the sale of non-strategic coalbed methane project at Hanging Woman Basin, offset 
by net positive price and engineering revisions of 50.0 BCFE.  Production in the Rocky Mountain region for 2009 
was 33.3 BCFE.  Total regional production was down five percent from 34.9 BCFE in 2008.  Adjusting for the 
effect of the divestitures, production in the region would have declined 1.3 BCFE, or four percent, year over year. 

The Elm Coulee Field is the highest value field in the region at year-end 2009.  The reserves in this field 

are predominately oil, and the Bakken is the formation of primary interest.  The field is largely developed with 
only a handful of remaining drilling locations identified as proved undeveloped. 

The Bakken and Three Forks formations in the Williston Basin will be our primary focus in 2010.  We 

plan to drill 17 horizontal wells targeting these formations in 2010.  The majority will be located in our Bear Den 
asset program in McKenzie and Williams counties in North Dakota where we have roughly 16,000 net acres.  
Additionally, we have built a 70,000 net acre position with potential for the Bakken and Three Forks in 
McKenzie, Williams, and Divide counties that we will test during 2010.  We are currently drilling a test well in 
Wyoming targeting the Niobrara formation as part of our ongoing exploration effort.  We plan to evaluate our 
results, as well as those of nearby competitors, during 2010. 

Reserves 

In December 2008, the SEC announced that it had approved revisions designed to modernize oil and gas 
reporting requirements.  A key revision to the rules pertains to commodity prices.  The economic producibility of 
reserves and discounted cash flows are now based on a 12-month average commodity price as opposed to a year-
end price in estimating reserves.  The prices used in the calculation of proved reserve estimates as of 
December 31, 2009, were $61.18 per Bbl and $3.87 per MMBTU for oil and natural gas, respectively.  These 
prices were 37 percent higher and 32 percent lower, respectively, than the year-end prices used to estimate 2008 
proved reserves, and 23 percent and 33 percent lower, respectively, than prices that would have been used the 
SEC’s previous methodology.  If the SEC’s prior methodology had been used for year-end 2009 proved reserves, 
the prices used would have been $79.36 per Bbl and $5.79 per MMBTU.   

Additional revisions to the SEC rules provide for the use of new technology to estimate proved reserves.  
Additionally, the definition of proved oil and gas reserves has been expanded to include non-traditional resources, 
which focuses on the marketable product rather than the method of extraction.  In addition to these regulatory 
changes, in 2009 we began recording estimates of proved reserve volumes for properties that we believe are 
reasonably certain to generate positive net cash flows on an undiscounted basis, that we have the intent to drill, 
and which meet our internal economic criteria for drilling.  Previously, we booked proved reserve volumes if the 
properties showed a positive PV-10 value, we had the intent to drill, and the wells met our economic criteria. 

The table below presents summary information with respect to the estimates of our proved oil and gas 

reserves for each of the years in the three-year period ended December 31, 2009.  We engaged Ryder Scott 
Company, L.P. (―Ryder Scott‖) to review internal engineering estimates for at least 80 percent of the PV-10 value 
of our proved reserves in 2009, 2008, and 2007, excluding our coalbed methane properties.  For 2008 and 2007, 
Netherland, Sewell and Associates, Inc. (―NSAI‖) prepared the reserve information for our coalbed methane 
projects at Hanging Woman Basin in the northern Powder River Basin and St. Mary’s non-operated coalbed 
methane interest in the Green River Basin.  We divested of all Hanging Woman Basin properties in the fourth 
quarter of 2009. 

We emphasize that reserve estimates are inherently imprecise and that estimates of all new discoveries 
and undeveloped locations are more imprecise than estimates of established producing oil and gas properties.  
Accordingly, these estimates are expected to change as new information becomes available in the future.  The PV-
10 values shown in the following table are not intended to represent the current market value of the estimated 
proved oil and gas reserves owned by St. Mary.  Neither prices nor costs have been escalated.  The following 
table should be read along with the section entitled ―Risk Factors – Risks Related to Our Business – The actual 
quantities and present values of our proved oil and natural gas reserves may be less than we have estimated.‖  No 
estimates of our proved reserves have been filed with or included in reports to any federal authority or agency, 
other than the SEC, since the beginning of the last fiscal year.

The ability to replace produced reserves is important to the sustainability of all exploration and 
production companies.  Our 2009 corporate ratio of reserves replaced through drilling activity was 100 percent.  
There were no material acquisitions made in 2009.  Four out of our five regions did not replace their respective 
regional production for the year.  The one exception, our South Texas & Gulf Coast region, replaced 400 percent 
of its production for 2009 due to the strong results in the Eagle Ford shale.  This metric is calculated using 
information from the Oil and Gas Reserve Quantities section of Note 16 – Disclosures about Oil and Gas 
Producing Activities of Part IV, Item 15 of this report.  The numerator consists of the sum of discoveries and 
extensions and infill reserves in an existing proved field, which is then divided by production.  We believe the 
concept of reserve replacement as described above, as well as permutations which may include other captions of 
the Oil and Gas Reserve Quantities section of Note 16 – Disclosures about Oil and Gas Producing Activities of 
Part IV, Item 15 of this report, are widely understood by those who make investment decisions related to the oil 
and gas exploration business.  For additional information about reserve replacement metrics, see the reserve 
replacement terms in the Glossary section of this report.

Proved Undeveloped Reserves 

As of December 31, 2009, we had 141.9 BCFE of proved undeveloped reserves, which is a decrease of 

7.8 BCFE or five percent compared with 149.7 of proved undeveloped reserves at December 31, 2008.  A 
negative revision of 19.1 BCFE was due to lower pricing in the gas weighted regions, particularly in the 
ArkLaTex region where 16.4 BCFE of mostly Cotton Valley proved undeveloped reserves became uneconomic 
using the new 12-month average pricing.  We added 43.6 BCFE of proved undeveloped reserves through our 
drilling program, 34.3 BCFE of which were extensions and discoveries, primarily in the Eagle Ford shale, as well 
as an additional 9.3 BCFE of infill proved undeveloped reserves that were mostly concentrated in the Cotton 
Valley and Bakken.  During the year, 7.0 BCFE were sold in divestitures, primarily in our Rocky Mountain 
region.  We invested approximately $57 million to convert 18.6 BCFE of proved undeveloped reserves in 2009, 
mainly in the Wolfberry properties in the Permian region and the Woodford shale in the Mid-Continent region.  
We had a negative revision of 6.7 BCFE due to downward performance revisions in our Wolfberry properties in 
the Permian region and 3.6 BCFE of proved undeveloped reserves were removed as a result of the five year 
limitation on the number of years that a proved undeveloped reserve may remain on the books without being 
developed.  As of December 31, 2009, we have no material proved undeveloped reserves that have been on the 
books in excess of five years.  As of December 31, 2009, estimated future development costs relating to proved 
undeveloped reserves are projected to be approximately $49 million, $129 million, and $56 million in 2010, 2011, 
and 2012, respectively.

Alternate Pricing Scenario 

The following table presents our December 31, 2009, reserves data and PV-10 value based on prices that 

would have been used under the SEC’s previous methodology of estimating reserves using year-end pricing.  If 
the SEC’s prior methodology had been used for year-end 2009 proved reserves, the prices used would have been 
$79.36 per barrel and $5.79 per MMBTU. All cost assumptions remain the same.

St. Mary’s policies regarding internal controls over the recording of reserves is structured to objectively 
and accurately estimate our oil and gas reserves quantities and values in compliance with the SEC’s regulations.  
Responsibility for compliance in reserves bookings is delegated to our reservoir engineering group, which is led 
by our Vice President of Engineering and Evaluation. 

Technical reviews are performed throughout the year by regional engineering and geologic staff who 

evaluate all available geological and engineering data.  This data in conjunction with economic data and 
ownership information is used in making a determination of proved reserve quantities.  The reserve process is 
overseen by Dennis A. Zubieta, Vice President - Engineering and Evaluation for St. Mary.  Mr. Zubieta joined 
St. Mary in June 2000 as a Corporate Acquisition & Divestiture Engineer, assumed the role of Reservoir Engineer 
in February 2003, and was appointed Reservoir Engineering Manager in August 2005.  Mr. Zubieta was 
employed by Burlington Resources Oil and Gas Company (formerly known as Meridian Oil, Inc) from June 1988 
to May 2000 in various operations and reservoir engineering capacities.  Mr. Zubieta received a Bachelor of 
Science degree in Petroleum Engineering from Montana Tech in May 1988.  The regional technical staff does not 
report directly to Mr. Zubieta; they report to either regional technical managers or directly to the regional manager 
in their respective region.  This is intended to promote objective and independent analysis within the reserves 
process.

Third-party Reserves Audit 

An independent audit is performed by Ryder Scott using their own engineering assumptions and 

economic data provided by St. Mary.  A minimum of 80 percent of the total calculated proved reserve PV-10 
value is audited by Ryder Scott.  In aggregate, the reserve values of the audited properties are required to be 
within 10 percent of St. Mary’s valuations on both a corporate and regional level.  Ryder Scott is an independent 
petroleum engineering consulting firm that has been providing petroleum consulting services throughout the 
world for over seventy years.  The technical person at Ryder Scott primarily responsible for overseeing the 
reserves audit is a Senior Vice President and holds a Bachelor of Science degree in Petroleum Engineering from 
the University of Missouri at Rolla in 1970 and is a registered Professional Engineer in the States of Colorado and 
Utah.  He is also a member of the Society of Petroleum Engineers.  The Ryder Scott report is included as 
Exhibit 99.1. 

In addition to a third party audit, our reserves are reviewed by senior management and the Audit 

Committee of St. Mary’s Board of Directors.  Senior management, which includes the President and Chief 
Executive Officer, the Executive Vice President and Chief Operating Officer, and the Executive Vice President 
and Chief Financial Officer, is responsible for reviewing and verifying that the estimate of proved reserves is 
reasonable, complete, and accurate.  The Audit Committee reviews the final reserves estimate in conjunction with 
Ryder Scott’s audit letter.  They may also meet with the key representative from Ryder Scott to discuss their 
process and findings.

Productive Wells 

As of December 31, 2009, St. Mary had working interests in 2,046 gross (1,000 net) productive oil wells 
and 3,154 gross (1,042 net) productive gas wells.  Productive wells are either producing wells or wells capable of 
commercial production although currently shut-in.  Multiple completions in the same wellbore are counted as one 
well.  A well is categorized under state reporting regulations as an oil well or a gas well based on the ratio of gas 
to oil produced when it first commenced production, and such designation may not be indicative of current 
production. 

Subsequent to year end, we have closed or plan to close on several divestitures of non-core properties, 
primarily in the Rocky Mountain region.  Upon closing of these transactions, we will have divested 425 gross 
(302 net) productive oil wells and 305 gross (93 net) productive gas wells. 

Drilling Activity 

All of our drilling activities are conducted on a contract basis with independent drilling contractors.  We 

do not own any drilling equipment.  The following table sets forth the wells drilled and recompleted in which 
St. Mary participated during each of the three years indicated:

have royalty interests. 

A productive well is an exploratory, development or extension well that is not a dry well.  A dry well 

(hole) is an exploratory, development, or extension well that proves to be incapable of producing either oil or gas 
in sufficient quantities to justify completion as an oil or gas well. 

As defined in the rules and regulations of the SEC, an exploratory well is a well drilled to find a new field 

or to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir.  A 
development well is part of a development project, which is defined as the means by which petroleum resources 
are brought to the status of economically producible.  The number of wells drilled refers to the number of wells 
completed at any time during the respective year, regardless of when drilling was initiated.  Completion refers to 
the installation of permanent equipment for production of oil or gas, or, in the case of a dry well, to reporting to 
the appropriate authority that the well has been abandoned. 

In addition to the wells drilled and completed in 2009 included in the table above, as of 

February 16, 2010, St. Mary is currently participating in the drilling of 25 gross wells, all of which are located in 
the continental United States.  We operate nine of these wells with the remaining 16 wells being operated by our 
partners.  On a net basis, we are drilling 7.6 net operated wells and are participating in 2.0 net non-operated

completed.  We operate 13 of those on a gross basis (10.2 net) and is participating with industry partners in 6 
gross (0.3 net) completion activities.  The vast majority, if not all, of these operations relate to the drilling of wells 
for primary production. 

Acreage 

The following table sets forth the gross and net acres of developed and undeveloped oil and gas leases, 
fee properties, mineral servitudes, and lease options held by St. Mary as of December 31, 2009.  Undeveloped 
acreage includes leasehold interests that may already have been classified as containing proved undeveloped 
reserves.

(1)  Developed acreage is acreage assigned to producing wells for the spacing unit of the producing formation.  Developed acreage of 

St. Mary’s properties that include multiple formations with different well spacing requirements may be considered undeveloped for 
certain formations, but have only been included as developed acreage in the presentation above. 

(2)  Undeveloped acreage is lease acreage on which wells have not been drilled or completed to a point that would permit the production 

of commercial quantities of oil and gas, regardless of whether such acreage contains estimated reserves. 

(3)  Subsequent to December 31, 2009, St. Mary divested certain non-core properties, which included leases covering approximately 26,100 

and 25,100 developed gross and net acres, respectively, and 18,600 and 15,000 undeveloped gross and net acres, respectively.  
Additionally, we entered into agreements to divest certain non-core properties, which included leases covering approximately 80,200 and 
44,500 developed gross and net acres, respectively, and 63,700 and 31,000 undeveloped gross and net acres, respectively.  

Delivery Commitments 

As of December 31, 2009, there were no material delivery commitments.  Subsequent to year end we are 

subject to a certain gathering through-put contract that requires a minimum volume delivery of 15 Bcf by 
January 1, 2013.  We will be required to pay $0.18 Mcf for any shortfall in delivering the minimum volume of 15 
Bcf.  At the current time, the company does not have proved developed reserves to offset this contractual liability, 
but fully intends to develop proved undeveloped reserves that will exceed the through-put commitment.

Major Customers 

During 2009, sales to Teppco Crude Oil LLC individually accounted for 12 percent of our total oil and 
gas production revenue.  During 2008 and 2007, no customer individually accounted for ten percent or more of 
our total oil and gas production revenue. 

Employees and Office Space 

As of February 16, 2010, we had 550 full-time employees.  None of our employees are subject to a 

collective bargaining agreement and we consider our relations with our employees to be good.  As of 
December 31, 2009, we lease approximately 79,000 square feet of office space in Denver, Colorado for our 
executive and administrative offices, of which approximately 9,000 square feet is subleased.  We lease 
approximately 22,000 square feet of office space in Tulsa, Oklahoma; approximately 22,000 square feet in 
Shreveport, Louisiana; approximately 26,000 square feet in Houston, Texas; approximately 17,000 square feet in 
Midland, Texas; approximately 36,000 square feet in Billings, Montana; approximately 6,000 square feet in 
Williston, North Dakota; and approximately 2,000 square feet in Casper, Wyoming. 

Title to Properties 

Substantially all of our working interests are held pursuant to leases from third parties.  A title opinion is 

usually obtained prior to the commencement of drilling operations.  We have obtained title opinions or have 
conducted a thorough title review on substantially all of our producing properties and believe that we have 
satisfactory title to such properties in accordance with standards generally accepted in the oil and gas industry.  
The majority of the value of our properties is subject to a mortgage under our credit facility, customary royalty 
interests, liens for current taxes, and other burdens that we believe do not materially interfere with the use of or 
affect the value of such properties.  We perform only a minimal title investigation before acquiring undeveloped 
leasehold. 

Seasonality 

Generally, but not always, the demand and price levels for natural gas increase during the colder winter 

months and decrease during the warmer summer months.  To lessen seasonal demand fluctuations, pipelines, 
utilities, local distribution companies, and industrial users utilize natural gas storage facilities and forward 
purchase some of their anticipated winter requirements during the summer.  However, increasing summertime 
demand for electricity is beginning to place increased demand on storage volumes.  Crude oil and the demand for 
heating oil are also impacted by generally higher prices in the winter and the summer driving season – although 
oil is much more driven by global supply and demand.  Seasonal anomalies such as mild winters sometimes 
lessen these fluctuations.  The impact of seasonality has somewhat been exacerbated by the overall supply and 
demand economics related to crude oil because there is a narrow margin of production capacity in excess of 
existing worldwide demand. 

Competition 

The oil and gas industry is intensely competitive, particularly with respect to capturing prospective oil and 
natural gas properties and oil and gas reserves.  We believe our leasehold position provides a sound foundation for 
a solid drilling program.  Our competitive position also depends on our geological, geophysical, and engineering 
expertise, and our financial resources.  We believe the location of our leasehold acreage, our exploration, drilling, 
and production expertise and available technologies, and the experience and knowledge of our management and 
industry partners enable us to compete effectively in our core operating and resource play areas.  Notwithstanding 
our talents and assets, we still face stiff competition from a substantial number of major and independent oil and 
gas companies who have larger technical staffs and greater financial and operational resources than we do.  Many 
of these companies not only engage in the acquisition, exploration, development, and production of oil and natural 
gas reserves, but also have refining operations, market refined products, own drilling rigs, and generate electricity.  
We also compete with other oil and natural gas companies in attempting to secure drilling rigs and other 
equipment and services necessary for the drilling and completion of wells.  Consequently, we may face shortages 

16 

 
or delays in securing these services from time to time.  We are seeing signs of tightening rig availability, although 
it is quite specific by region.  The oil and natural gas industry also faces competition from alternative fuel sources, 
including other fossil fuels such as coal and imported liquefied natural gas.  Competitive conditions may be 
affected by future legislation and regulations as the U.S. develops new energy and climate-related policies.  
Finally, we also compete for people.  Throughout the industry, the need to attract and retain talented people has 
grown at a time when the number of people available is constrained.  We are not insulated from this resource 
constraint, and we must compete effectively in this market in order to be successful. 

Government Regulations 

Our business is extensively regulated by numerous federal, state, and local laws and government 
regulations.  These laws and regulations may be changed from time to time in response to economic or political 
conditions, or other developments, and our regulatory burden may increase in the future.  Laws and regulations 
increase our cost of doing business and, consequently, affect our profitability.  However, we do not believe that 
we are affected to a materially greater or lesser extent than others in our industry. 

Energy Regulations.  Many of the states in which we conduct our operations have adopted laws and 

regulations governing the exploration for and production of crude oil and natural gas, including laws and 
regulations requiring permits for the drilling of wells, imposing bonding requirements in order to drill or operate 
wells, and governing the location of wells, the method of drilling and casing wells, the surface use and restoration 
of properties upon which wells are drilled, and the plugging and abandonment of wells.  Our operations are also 
subject to various state conservation laws and regulations, including regulations governing the size of drilling and 
spacing units or proration units, the number of wells which may be drilled in an area, the spacing of wells, and the 
unitization or pooling of crude oil and natural gas properties.  In addition, state conservation laws sometimes 
establish maximum rates of production from crude oil and natural gas wells, generally prohibit the venting or 
flaring of natural gas, and may impose certain requirements regarding the ratability or fair apportionment of 
production from fields and individual wells. 

Some of our operations are conducted on federal lands pursuant to oil and gas leases administered by the 

Bureau of Land Management (BLM) or the Minerals Management Service (MMS).  These leases contain 
relatively standardized terms and require compliance with detailed regulations and orders, which are subject to 
change.  In addition to permits required from other regulatory agencies, lessees must obtain a permit from the 
BLM or MMS before drilling and comply with regulations governing, among other things, engineering and 
construction specifications for production facilities, safety procedures, the valuation of production and payment of 
royalties, the removal of facilities, and the posting of bonds to ensure that lessee obligations are met.  Under 
certain circumstances, the BLM or the MMS, as applicable, may require our operations on federal leases to be 
suspended or terminated. 

In January 2010, the BLM announced that it will be issuing a new draft oil and gas leasing policy that will 

require, among other things, a more detailed environmental review prior to leasing oil and natural gas resources, 
increased public engagement in the development of master leasing and development plans prior to leasing areas 
where intensive new oil and gas development is anticipated, and a comprehensive parcel review process.  As the 
policy has not yet been released, we are not able to determine the impact these potential leasing policy changes 
may have on our business. 

Our sales of natural gas are affected by the availability, terms, and cost of natural gas pipeline 
transportation.  The Federal Energy Regulatory Commission (FERC) has jurisdiction over the transportation and 
sale for resale of natural gas in interstate commerce.  The FERC’s current regulatory framework generally 
provides for a competitive and open access market for sales and transportation of natural gas.  However, FERC 
regulations continue to affect the midstream and transportation segments of the industry, and thus can indirectly 
affect the sales prices we receive for natural gas production.  In addition, the less stringent regulatory approach 
recently pursued by the FERC and the U.S. Congress may not continue indefinitely. 

17 

 
 
 
Environmental, Health and Safety Regulations.  Our operations are subject to stringent federal, state, and 

local laws and regulations relating to the protection of the environment and human health and safety.  
Environmental laws and regulations may require that permits be obtained before drilling commences, restrict the 
types, quantities, and concentration of various substances that can be released into the environment in connection 
with drilling and production activities, govern the handling and disposal of waste material, and limit or prohibit 
drilling activities on certain lands lying within wilderness, wetlands, and other protected areas, including areas 
containing endangered animal species.  As a result, these laws and regulations may substantially increase the costs 
of exploring for, developing, or producing oil and gas and may prevent or delay the commencement or 
continuation of certain projects.  In addition, these laws and regulations may impose substantial clean-up, 
remediation, and other obligations in the event of any discharges or emissions in violation of these laws and 
regulations.  Further, possible regulations related to global warming or climate change could have an adverse 
effect on our operations and the demand for oil and natural gas.  See ―Risk Factors – Risks Related to Our 
Business - Possible regulations related to global warming or climate change could have an adverse effect on our 
operations and the demand for oil and natural gas.‖ 

Hydraulic fracturing is a common process in our industry of creating artificial cracks, or fractures, in deep 

underground rock formations through the pressurized injection of water, sand and other additives to enable oil or 
natural gas to move more easily through the rock pores to a production well.  This process is often necessary to 
produce commercial quantities of oil and natural gas from many reservoirs, especially shale rock formations.  We 
routinely utilize hydraulic fracturing techniques in many of our reservoirs, and our shale resource programs utilize 
or contemplate the utilization of hydraulic fracturing.  Currently, regulation of hydraulic fracturing is primarily 
conducted at the state level through permitting and other compliance requirements.  Legislative and regulatory 
efforts at the federal level and in some states have been made which could result in additional regulations and 
permitting requirements.  Those additional regulations and permitting requirements, as well as other regulatory 
developments, could lead to significant operational delays and increased operating costs, and make it more 
difficult to perform hydraulic fracturing. 

Federal and state occupational safety and health laws require us to organize and maintain information 

about hazardous materials used, released, or produced in our operations.  Some of this information must be 
provided to our employees, state and local governmental authorities, and local citizens.  We are also subject to the 
requirements and reporting framework set forth in the federal workplace standards. 

To date we have not experienced any materially adverse effect on our operations from obligations under 

environmental, health, and safety laws and regulations.  We believe that we are in substantial compliance with 
currently applicable environmental, health, and safety laws and regulations, and that continued compliance with 
existing requirements would not have a materially adverse impact on us.

Glossary of Oil and Natural Gas Terms 

The oil and natural gas terms defined in this section are used throughout this Form 10-K.  The definitions 

of the terms developed reserves, exploratory well, field, proved reserves, and undeveloped reserves have been 
abbreviated from the respective definitions under Rule 4-10(a) of Regulation S-X promulgated by the SEC.  The 
entire definitions of those terms under Rule 4-10(a) of Regulation S-X can be located through the SEC’s website 
at www.sec.gov. 

Bbl.  One stock tank barrel, or 42 U.S. gallons liquid volume, used in reference to oil or other liquid 
hydrocarbons. 

Bcf.  Billion cubic feet, used in reference to natural gas. 

BCFE.  Billion cubic feet of natural gas equivalent.  Natural gas equivalents are determined using the volumetric 
ratio of six Mcf of natural gas to one Bbl of oil. 

BOE.  Barrels of oil equivalent.  Oil equivalents are determined using the volumetric ratio of six Mcf of natural 
gas to one Bbl of oil. 

Developed reserves.  With respect to reserves as of December 31, 2009, and dates thereafter, the applicable SEC 
definition of developed reserves is reserves that can be expected to be recovered: (i) through existing wells with 
existing equipment and operating methods or in which the cost of the required equipment is relatively minor 
compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational 
at the time of the reserves estimate if the extraction is by means not involving a well.  With respect to reserves as 
of dates prior to December 31, 2009, the applicable SEC definition of proved developed reserves was proved 
reserves that can be expected to be recovered through existing wells with existing equipment and operating 
methods. 

Development well.  A well drilled within the proved area of an oil or natural gas reservoir to the depth of a 
stratigraphic horizon known to be productive. 

Dry hole.  A well found to be incapable of producing either oil or natural gas in commercial quantities. 

Exploratory well.  With respect to wells as of December 31, 2009, and dates thereafter, the applicable SEC 
definition of exploratory well is a well drilled to find a new field or to find a new reservoir in a field previously 
found to be productive of oil or natural gas in another reservoir.  With respect to wells as of dates prior to 
December 31, 2009, the applicable SEC definition of exploratory well was a well drilled to find and produce oil 
or natural gas in an unproved area, to find a new reservoir in a field previously found to be productive of oil or 
natural gas in another reservoir, or to extend a known reservoir. 

Farmout.  An assignment of an interest in a drilling location and related acreage conditioned upon the drilling of a 
well on that location. 

Fee land.  The most extensive interest that can be owned in land, including surface and mineral (including oil and 
natural gas) rights. 

Field.  An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same 
individual geological structural feature and/or stratigraphic condition. 

Finding cost.  Expressed in dollars per MCFE.  Finding cost metrics provide information as to the cost of adding 
proved reserves from various activities, and are widely utilized within the exploration and production industry, as 
well as by investors.  The information used to calculate these metrics is included in Note 15 – Oil and Gas 
Activities and Note 16 – Disclosures about Oil and Gas Producing Activities of the Notes to Consolidated 
Financial Statements included in this report.  It should be noted that finding cost metrics have limitations.  For 
example, exploration efforts related to a particular set of proved reserve additions may extend over several years.  

21 

 
As a result, the exploration costs incurred in earlier periods are not included in the amount of exploration costs 
incurred during the period in which that set of proved reserves is added.  In addition, consistent with industry 
practice, future capital costs to develop proved undeveloped reserves are not included in costs incurred.  Since the 
additional development costs that will need to be incurred in the future before the proved undeveloped reserves 
are ultimately produced are not included in the amount of costs incurred during the period in which those reserves 
were added, those development costs in future periods will be reflected in the costs associated with adding a 
different set of reserves.  The calculations of various finding cost metrics are explained below. 

Finding cost – Drilling, excluding revisions.  Calculated by dividing the amount of costs incurred for 
development and exploration activities, by the amount of estimated net proved reserves added through 
discoveries, extensions, and infill drilling, during the same period. 

Finding cost – Drilling, including revisions.  Calculated by dividing the amount of costs incurred for 
development and exploration activities, by the amount of estimated net proved reserves added through 
discoveries, extensions, and infill drilling, and revisions of previous estimates during the same period. 

Finding cost – Drilling and acquisitions, excluding revisions.  Calculated by dividing the amount of costs 
incurred for development, exploration and acquisition of proved properties, by the amount of estimated 
net proved reserves added through discoveries, extensions, infill drilling and acquisitions during the same 
period. 

Finding cost – Drilling and acquisitions, including revisions.  Calculated by dividing the amount of costs 
incurred for development, exploration and acquisition of proved properties, by the amount of estimated 
net proved reserves added through discoveries, extensions, and infill drilling, revisions of previous 
estimates, and acquisitions during the same period. 

Finding cost –All in, including sales of reserves.  Calculated by dividing the amount of total capital 
expenditures for oil and natural gas activities, by the amount of estimated net proved reserves added 
through discoveries, extensions, infill drilling, acquisitions, and revisions of previous estimates less sales 
of reserves during the same period. 

Formation.  A succession of sedimentary beds that were deposited under the same general geologic conditions. 

Gross acre.  An acre in which a working interest is owned. 

Gross well.  A well in which a working interest is owned. 

Horizontal wells.  Wells which are drilled at angles greater than 70 degrees from vertical. 

Lease operating expenses.  The expenses incurred in the lifting of oil or natural gas from a producing formation to 
the surface, constituting part of the current operating expenses of a working interest, and also including labor, 
superintendence, supplies, repairs, maintenance, allocated overhead costs, and other expenses incidental to 
production, but not including lease acquisition, drilling, or completion costs. 

MBbl.  One thousand barrels of oil or other liquid hydrocarbons. 

MMBbl.  One million barrels of oil or other liquid hydrocarbons. 

MBOE.  One thousand barrels of oil equivalent.  Oil equivalents are determined using the volumetric ratio of six 
Mcf of natural gas to one Bbl of oil. 

MMBOE.  One million barrels of oil equivalent.  Oil equivalents are determined using the volumetric ratio of six 
Mcf of natural gas to one Bbl of oil. 

Mcf.  One thousand cubic feet, used in reference to natural gas. 

22 

 
MCFE.  One thousand cubic feet of natural gas equivalent.  Natural gas equivalents are determined using the 
volumetric ratio of six Mcf of natural gas to one Bbl of oil. 

MMcf.  One million cubic feet, used in reference to natural gas. 

MMCFE.  One million cubic feet of natural gas equivalent.  Natural gas equivalents are determined using the 
volumetric ratio of six Mcf of natural gas to one Bbl of oil. 

MMBtu.  One million British Thermal Units.  A British Thermal Unit is the amount of heat required to raise the 
temperature of a one-pound mass of water by one degree Fahrenheit.  

Net acres or net wells.  The sum of our fractional working interests owned in gross acres or gross wells. 

Net asset value per share.  The result of the fair market value of total assets less total liabilities, divided by the 
total number of outstanding shares of common stock. 

NYMEX.  New York Mercantile Exchange. 

PV-10 value.  The present value of estimated future gross revenue to be generated from the production of 
estimated net proved reserves, net of estimated production and future development costs, based on prices used in 
estimating the proved reserves and costs in effect as of the date indicated (unless such costs are subject to change 
pursuant to contractual provisions), without giving effect to non-property related expenses such as general and 
administrative expenses, debt service, future income tax expenses, or depreciation, depletion, and amortization, 
discounted using an annual discount rate of ten percent.  While this measure does not include the effect of income 
taxes as it would in the use of the standardized measure of discounted future net cash flows calculation, it does 
provide an indicative representation of the relative value of the Company on a comparative basis to other 
companies and from period to period. 

Productive well.  A well that is producing oil or natural gas or that is capable of commercial production. 

Proved reserves.  With respect to reserves as of December 31, 2009, and dates thereafter, the applicable SEC 
definition of proved reserves is those quantities of oil and gas, which, by analysis of geoscience and engineering 
data, can be estimated with reasonable certainty to be economically producible – from a given date forward, from 
known reservoirs, and under existing economic conditions, operating methods, and government regulations – 
prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is 
reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation.  
Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be 
determined, and the price to be used is the average price during the 12-month period prior to the ending date of 
the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month 
price for each month within such period, unless prices are defined by contractual arrangements, excluding 
escalations based upon future conditions.  With respect to reserves as of dates prior to December 31, 2009, the 
applicable SEC definition of proved reserves was the estimated quantities of crude oil, natural gas, and natural gas 
liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future 
years from known reservoirs under existing economic and operating conditions, meaning prices and costs as of 
the date the estimate is made. 

Recompletion.  A completion in an existing wellbore in a formation other than that in which the well has 
previously been completed. 

Reserve life.  Expressed in years, represents the estimated net proved reserves at a specified date divided by actual 
production for the preceding 12-month period. 

Reserve replacement.  Reserve replacement metrics are used as indicators of a company’s ability to replenish 
annual production volumes and grow its reserves, and provide information related to how successful a company is 
at growing its proved reserve base.  These are believed to be useful non-GAAP measures that are widely utilized 

23 

 
within the exploration and production industry, as well as by investors.  They are easily calculable metrics, and 
the information used to calculate these metrics is included in Note 16 – Disclosures about Oil and Gas Producing 
Activities of the Notes to Consolidated Financial Statements included in this report.  It should be noted that 
reserve replacement metrics have limitations.  They are limited because they typically vary widely based on the 
extent and timing of new discoveries and property acquisitions.  Their predictive and comparative value is also 
limited for the same reasons.  In addition, since the metrics do not embed the cost or timing of future production 
of new reserves, they cannot be used as a measure of value creation.  The calculations of various reserve 
replacement metrics are explained below. 

Reserve replacement – Drilling, excluding revisions.  Calculated as a numerator comprised of the sum of 
reserve extensions and discoveries and infill reserves in an existing proved field divided by production for 
that same period.  This metric is an indicator of the relative success a company is having in replacing its 
production through drilling activity. 

Reserve replacement – Drilling, including revisions.  Calculated as a numerator comprised of the sum of 
reserve extensions, discoveries, and infill reserves, and revisions and previous estimates in an existing 
proved field divided by production for that same period.  This metric is an indicator of the relative success 
a company is having in replacing its production through drilling activity. 

Reserve replacement – Drilling and acquisitions, excluding revisions.  Calculated as a numerator 
comprised of the sum of reserve acquisitions and reserve extensions and discoveries and infill reserves in 
an existing proved field divided by production for that same period.  This metric is an indicator of the 
relative success a company is having in replacing its production through drilling and acquisition activities. 

Reserve replacement – Drilling and acquisitions, including revisions.  Calculated as a numerator 
comprised of the sum of reserve acquisitions and reserve extensions, discoveries, and infill reserves, and 
revisions and previous estimates in an existing proved field divided by production for that same period.  
This metric is an indicator of the relative success a company is having in replacing its production through 
drilling and acquisition activities. 

Reserve replacement percentage – All in, excluding sales of reserves.  The sum of reserve extensions and 
discoveries, infill drilling, reserve acquisitions, and reserve revisions of previous estimates for a specified 
period of time divided by production for that same period. 

Reserve replacement percentage –All in, including sales of reserves.  The sum of sales of reserves, infill 
drilling, reserve extensions and discoveries, reserve acquisitions, and reserve revisions of previous 
estimates for a specified period of time divided by production for that same period. 

Reservoir.  A porous and permeable underground formation containing a natural accumulation of producible oil 
and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other 
reservoirs. 

Resource play.  A term used to describe an accumulation of oil and/or natural gas resources known to exist over a 
large area expanse, which when compared to a conventional play typically has a lower expected geological and/or 
commercial development risk. 

Royalty.  The amount or fee paid to the owner of mineral rights, expressed as a percentage or fraction of gross 
income from oil and natural gas produced and sold unencumbered by expenses relating to the drilling, 
completing, and operating of the affected well. 

Royalty interest.  An interest in an oil and natural gas property entitling the owner to shares of oil and natural gas 
production free of costs of exploration, development, and production operations. 

Seismic.  An exploration method of sending energy waves or sound waves into the earth and recording the wave 
reflections to indicate the type, size, shape, and depth of subsurface rock formations. 

24 

 
Shale.  Fine-grained sedimentary rock composed mostly of consolidated clay or mud.  Shale is the most 
frequently occurring sedimentary rock. 

Standardized measure of discounted future net cash flows.  The discounted future net cash flows relating to 
proved reserves based on prices used in estimating the reserves, year-end costs, and statutory tax rates, and a ten 
percent annual discount rate.  The information for this calculation is included in the note regarding disclosures 
about oil and gas producing activities contained in the Notes to Consolidated Financial Statements included in this 
Form 10-K. 

Undeveloped acreage.  Lease acreage on which wells have not been drilled or completed to a point that would 
permit the production of commercial quantities of oil or natural gas, regardless of whether such acreage contains 
estimated net proved reserves. 

Undeveloped reserves.  Reserves that are expected to be recovered from new wells on undrilled acreage, or from 
existing wells where a relatively major expenditure is required for recompletion.  With respect to reserves as of 
December 31, 2009, and dates thereafter, the applicable SEC definition of undeveloped reserves provides that 
undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted 
indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer 
time. 

Working interest.  The operating interest that gives the owner the right to drill, produce, and conduct operating 
activities on the property and to share in the production, sales, and costs.

ITEM 1A. 

RISK FACTORS 

In addition to the other information included in this Form 10-K, the following risk factors should be 

carefully considered when evaluating St. Mary. 

Risks Related to Our Business 

Oil and natural gas prices are volatile, and declines in prices adversely affect our profitability, financial 
condition, cash flows, access to capital, and ability to grow. 

Our revenues, operating results, profitability, future rate of growth, and the carrying value of our oil and 

natural gas properties depend heavily on the prices we receive for oil and natural gas sales.  Oil and natural gas 
prices also affect our cash flows available for capital expenditures and other items, our borrowing capacity, and 
the amount and value of our oil and natural gas reserves.  For example, the amount of our borrowing base under 
our credit facility is subject to periodic redeterminations based on oil and natural gas prices specified by our bank 
group at the time of redetermination.  In addition, we may have oil and natural gas property impairments or 
downward revisions of estimates of proved reserves if prices fall significantly. 

Historically, the markets for oil and natural gas have been volatile and they are likely to continue to be 

volatile.  Wide fluctuations in oil and natural gas prices may result from relatively minor changes in the supply of 
and demand for oil and natural gas, market uncertainty, and other factors that are beyond our control, including: 

  Global and domestic supplies of oil and natural gas, and the productive capacity of the industry as a 

whole 

  The level of consumer demand for oil and natural gas 

  Overall global and domestic economic conditions 

  Weather conditions 

  The availability and capacity of transportation or refining facilities in regional or localized areas that 

may affect the realized price for oil or natural gas 

  The price and level of foreign imports of crude oil, refined petroleum products, and liquefied natural 

gas 

  The price and availability of alternative fuels 

  Technological advances affecting energy consumption 

  The ability of the members of the Organization of Petroleum Exporting Countries to agree to and 

maintain oil price and production controls 

  Political instability or armed conflict in oil or natural gas producing regions 

  Strengthening and weakening of the U.S dollar relative to other currencies 

  Governmental regulations and taxes. 

These factors and the volatility of oil and natural gas markets make it extremely difficult to predict future 

oil and natural gas price movements with any certainty.  Declines in oil or natural gas prices would reduce our 
revenues and could also reduce the amount of oil and natural gas that we can produce economically, which could 
have a materially adverse effect on us. 

26 

 
Continued weakness in economic conditions or uncertainty in financial markets may have material adverse 
impacts on our business that we cannot predict. 

U.S. and global economies and financial systems have recently experienced turmoil and upheaval 
characterized by extreme volatility and declines in prices of securities, diminished liquidity and credit availability, 
inability to access capital markets, the bankruptcy, failure, collapse or sale of financial institutions, increased 
levels of unemployment, and an unprecedented level of intervention by the U.S. federal government and other 
governments.  Although some portions of the economy appear to have stabilized and there have been signs of the 
beginning of recovery, the extent and timing of a recovery, and whether it can be sustained, are uncertain.  
Continued weakness in the U.S. or global economies could materially adversely affect our business and financial 
condition.  For example: 

• 

• 

• 

• 

the demand for oil and natural gas in the U.S. has declined and may remain at low levels or further 
decline if economic conditions remain weak, and continue to negatively impact our revenues, 
margins, profitability, operating cash flows, liquidity and financial condition 

the tightening of credit or lack of credit availability to our customers could adversely affect our ability 
to collect our trade receivables 

our ability to access the capital markets may be restricted at a time when we would like, or need, to 
raise capital for our business, including for exploration and/or development of our reserves 

our commodity hedging arrangements could become ineffective if our counterparties are unable to 
perform their obligations or seek bankruptcy protection. 

If we are unable to replace reserves, we will not be able to sustain production. 

Our future operations depend on our ability to find, develop, or acquire oil and natural gas reserves that 

are economically producible.  Our properties produce oil and natural gas at a declining rate over time.  In order to 
maintain current production rates, we must locate and develop or acquire new oil and natural gas reserves to 
replace those being depleted by production.  In addition, competition for the acquisition of producing oil and 
natural gas properties is intense and many of our competitors have financial and other resources needed to 
evaluate and integrate acquisitions that are substantially greater than those available to us.  Therefore, we may not 
be able to acquire oil and natural gas properties that contain economically producible reserves, or we may not be 
able to acquire such properties at prices acceptable to us.  Without successful drilling or acquisition activities, our 
reserves, production, and revenues will decline over time. 

Substantial capital is required to replace our reserves. 

We must make substantial capital expenditures to find, acquire, develop, and produce oil and natural gas 
reserves.  Future cash flows and the availability of financing are subject to a number of factors, such as the level 
of production from existing wells, prices received for oil and natural gas sales, our success in locating and 
developing and acquiring new reserves, and the orderly functioning of credit and capital markets.  When oil or 
natural gas prices decrease or if we encounter operating difficulties that result in our cash flows from operations 
being less than expected, we must reduce our capital expenditures unless we can raise additional funds through 
debt or equity financing or the divestment of assets.  Debt or equity financing may not always be available to us in 
sufficient amounts or on acceptable terms, and the proceeds offered to us for potential divestitures may not always 
be of acceptable value to us. 

When our revenues decrease due to lower oil or natural gas prices, decreased production, or other reasons, 

and if we cannot obtain capital through our revolving credit facility, other acceptable debt or equity financing 
arrangements, or the sale of non-core assets, our ability to execute development plans, replace our reserves, secure 
our acreage, or maintain production levels could be greatly limited. 

27 

 
The debt and equity financing markets have recently been constrained due to the global and domestic 

economic and financial downturn, and it is possible that circumstances may arise where one or more of the twelve 
participating banks in our credit facility, at some point, may not be able to fulfill their portion of the lending 
commitments to us under the facility.  Adverse conditions in the credit markets may increase the cost of 
borrowings and decrease our ability to access new sources of capital. 

Competition in our industry is intense, and many of our competitors have greater financial, technical, and human 
resources than we do. 

We face intense competition from major oil companies, independent oil and natural gas exploration and 

production companies, financial buyers, and institutional and individual investors who seek oil and natural gas 
property investments throughout the world, as well as the equipment, expertise, labor, and materials required to 
operate oil and natural gas properties.  Many of our competitors have financial, technical, and other resources 
vastly exceeding those available to us, and many oil and natural gas properties are sold in a competitive bidding 
process in which our competitors may be able and willing to pay more for development prospects and productive 
properties, or in which our competitors have technological information or expertise that is not available to us to 
evaluate and successfully bid for the properties.  In addition, shortages of equipment, labor, or materials as a 
result of intense competition may result in increased costs or the inability to obtain those resources as needed.  We 
may not be successful in acquiring and developing profitable properties in the face of this competition. 

We also compete for human resources.  Over the last few years, the need for talented people across all 

disciplines in the industry has grown, while the number of people available has been constrained. 

The actual quantities and present values of our proved oil and natural gas reserves may be less than we have 
estimated. 

This Form 10-K and other SEC filings by us contain estimates of our proved oil and natural gas reserves 

and the estimated future net revenues from those reserves.  These estimates are based on various assumptions, 
including assumptions required by the SEC relating to oil and natural gas prices, drilling and operating expenses, 
capital expenditures, taxes, timing of operations, and availability of funds.  The process of estimating oil and 
natural gas reserves is complex.  The process involves significant decisions and assumptions in the evaluation of 
available geological, geophysical, engineering, and economic data for each reservoir.  These estimates are 
dependent on many variables, and therefore changes often occur as these variables evolve.  Therefore, these 
estimates are inherently imprecise. 

Actual future production, oil and natural gas prices, revenues, production taxes, development 
expenditures, operating expenses, and quantities of producible oil and natural gas reserves will most likely vary 
from those estimated.  Any significant variance could materially affect the estimated quantities of and present 
values related to proved reserves disclosed by us, and the actual quantities and present values may be less than we 
have previously estimated.  In addition, we may adjust estimates of proved reserves to reflect production history, 
results of exploration and development activity, prevailing oil and natural gas prices, costs to develop and operate 
properties, and other factors, many of which are beyond our control.  Our properties may also be susceptible to 
hydrocarbon drainage from production on adjacent properties. 

As of December 31, 2009, approximately 18 percent, or 142 BCFE, of our estimated proved reserves 
were proved undeveloped, and approximately 9 percent, or 73 BCFE, were proved developed non-producing.  
Estimates of proved undeveloped reserves and proved developed non-producing reserves are nearly always based 
on volumetric calculations rather than the performance data used to estimate producing reserves.  In order to 
develop our proved undeveloped reserves, we estimate approximately $296 million of capital expenditures would 
be required.  Production revenues from proved developed non-producing reserves will not be realized until 
sometime in the future and after some investment of capital.  In order to bring production on-line for our proved 
developed non-producing reserves, we estimate capital expenditures of approximately $44 million will be 
deployed in future years.  Although we have estimated our reserves and the costs associated with these reserves in 
accordance with industry standards, estimated costs may not be accurate, development may not occur as 
scheduled and actual results may not occur as estimated.  The balance of our currently anticipated capital 

28 

 
expenditures for 2010 is directed towards projects that are not yet classified within the construct of proved 
reserves as defined by Regulation S-X promulgated by the SEC. 

You should not assume that the PV-10 value and standardized measure of discounted future net cash 

flows included in this Form 10-K represent the current market value of our estimated proved oil and natural gas 
reserves.  Management has based the estimated discounted future net cash flows from proved reserves on price 
and cost assumptions required by the SEC, whereas actual future prices and costs may be materially higher or 
lower.  For example, values of our reserves as of December 31, 2009, were estimated using a calculated 12-month 
average sales price of $3.87 per MMBtu of natural gas (NYMEX Henry Hub spot price) and $61.18 per Bbl of oil 
(NYMEX West Texas Intermediate spot price).  We then adjust these base prices to reflect appropriate basis, 
quality, and location differentials over that period in estimating our proved reserves.  During 2009, our monthly 
average realized natural gas prices, excluding the effect of hedging, were as high as $5.48 per Mcf and as low as 
$2.96 per Mcf.  For the same period, our monthly average realized oil prices before hedging were as high as 
$70.31 per Bbl and as low as $30.37 per Bbl.  Many other factors will affect actual future net cash flows, 
including: 

  Amount and timing of actual production 

  Supply and demand for oil and natural gas 

  Curtailments or increases in consumption by oil purchasers and natural gas pipelines 

  Changes in government regulations or taxes. 

The timing of production from oil and natural gas properties and of related expenses affects the timing of 
actual future net cash flows from proved reserves, and thus their actual present value.  Our actual future net cash 
flows could be less than the estimated future net cash flows for purposes of computing PV-10 values.  In addition, 
the ten percent discount factor required by the SEC to be used to calculate PV-10 values for reporting purposes is 
not necessarily the most appropriate discount factor given actual interest rates, costs of capital, and other risks to 
which our business and the oil and natural gas industry in general are subject. 

Reserve estimates as of December 31, 2009, have been prepared under the SEC’s new rules for oil and 
gas reporting that are effective for fiscal years ending on or after December 31, 2009.  These new rules require 
SEC reporting companies to prepare their reserve estimates using, among other things, revised reserve definitions 
and revised pricing based on 12-month unweighted first-day-of-the-month average pricing, instead of the prior 
requirement to use pricing at the end of the period.  The SEC has released only limited interpretive guidance 
regarding reporting of reserve estimates under the new rules and may not issue further interpretive guidance on 
the new rules in the near future.  The interpretation of these rules and their applicability in different situations 
remains unclear in many respects.  Changing interpretations of the rules or disagreements with our interpretations 
could result in revisions to our reserve estimates or write-downs in our reserves. 

Our property acquisitions may not be worth what we paid due to uncertainties in evaluating recoverable reserves 
and other expected benefits, as well as potential liabilities. 

Successful property acquisitions require an assessment of a number of factors beyond our control.  These 

factors include exploration potential, future oil and natural gas prices, operating costs, and potential 
environmental and other liabilities.  These assessments are not precise and their accuracy is inherently uncertain. 

In connection with our acquisitions, we perform a customary review of the acquired properties that will 
not necessarily reveal all existing or potential problems.  In addition, our review may not allow us to fully assess 
the potential deficiencies of the properties.  We do not inspect every well, and even when we inspect a well we 
may not discover structural, subsurface, or environmental problems that may exist or arise.  We may not be 
entitled to contractual indemnification for pre-closing liabilities, including environmental liabilities.  Normally, 
we acquire interests in properties on an ―as is‖ basis with limited remedies for breaches of representations and 
warranties. 

29 

 
In addition, significant acquisitions can change the nature of our operations and business if the acquired 

properties have substantially different operating and geological characteristics or are in different geographic 
locations than our existing properties.  To the extent acquired properties are substantially different than our 
existing properties, our ability to efficiently realize the expected economic benefits of such acquisitions may be 
limited. 

Integrating acquired properties and businesses involves a number of other special risks, including the risk 

that management may be distracted from normal business concerns by the need to integrate operations and 
systems as well as retain and assimilate additional employees.  Therefore, we may not be able to realize all of the 
anticipated benefits of our acquisitions. 

Exploration and development drilling may not result in commercially producible reserves. 

Oil and natural gas drilling and production activities are subject to numerous risks, including the risk that 

no commercially producible oil or natural gas will be found.  The cost of drilling and completing wells is often 
uncertain, and oil and natural gas drilling and production activities may be shortened, delayed, or canceled as a 
result of a variety of factors, many of which are beyond our control.  These factors include: 

  Unexpected drilling conditions 

  Title problems 

  Pressure or geologic irregularities in formations 

  Equipment failures or accidents 

  Hurricanes or other adverse weather conditions 

  Compliance with environmental and other governmental requirements 

  Shortages or delays in the availability of or increases in the cost of drilling rigs and crews, fracture 

stimulation crews and equipment, chemicals, and supplies. 

The prevailing prices of oil and natural gas affect the cost of and the demand for drilling rigs, production 

equipment, and related services.  However, changes in costs may not occur simultaneously with corresponding 
changes in commodity prices.  The availability of drilling rigs can vary significantly from region to region at any 
particular time.  Although land drilling rigs can be moved from one region to another in response to changes in 
levels of demand, an undersupply of rigs in any region may result in drilling delays and higher drilling costs for 
the rigs that are available in that region.  In addition, the recent economic and financial downturn has adversely 
affected the financial condition of some drilling contractors, which may constrain the availability of drilling 
services in some areas. 

Another significant risk inherent in our drilling plans is the need to obtain drilling permits from state, 

local, and other governmental authorities.  Delays in obtaining regulatory approvals and drilling permits, 
including delays which jeopardize our ability to realize the potential benefits from leased properties within the 
applicable lease periods, the failure to obtain a drilling permit for a well, or the receipt of a permit with 
unreasonable conditions or costs could have a materially adverse effect on our ability to explore on or develop our 
properties. 

The wells we drill may not be productive and we may not recover all or any portion of our investment in 
such wells.  The seismic data and other technologies we use do not allow us to know conclusively prior to drilling 
a well if oil or natural gas is present, or whether it can be produced economically.  The cost of drilling, 
completing, and operating a well is often uncertain, and cost factors can adversely affect the economics of a 
project.  Drilling activities can result in dry holes or wells that are productive but do not produce sufficient net 
revenues after operating and other costs to cover initial drilling and completion costs. 

30 

 
Drilling results in our newer shale plays, such as the Eagle Ford, Haynesville, and Marcellus shales, may 
be more uncertain than in shale plays that are more developed and have longer established production histories.  
For example, our experience with horizontal drilling in these shales, as well as the industry’s drilling and 
production history, is more limited than in the Woodford shale play, and we have less information with respect to 
the ultimate recoverable reserves and the production decline rates in these shales than we have in other areas in 
which we operate.  Completion techniques that have proven to be successful in other shale formations to 
maximize recoveries are being used in the early development of these new shales; however, we can provide no 
assurance of the ultimate success of these drilling and completion techniques.  Moreover, the recent growth in 
exploration in the Marcellus shale has drawn intense scrutiny from environmental interest groups, regulatory 
agencies, and other governmental entities.  As a result, we may face significant opposition to our operations in 
that area that may make it difficult to obtain permits and other needed authorizations to operate or otherwise make 
operating more costly or difficult than operating elsewhere. 

In addition, a significant part of our strategy involves increasing our drilling location inventories for 

multi-year programs scheduled out over several years.  Such multi-year drilling inventories can be more 
susceptible to long-term horizon uncertainties that could materially alter the occurrence or timing of actual 
drilling.  Because of these uncertainties, we do not know if the potential drilling locations we have identified will 
ever be drilled, although we have the present intent to do so, or if we will be able to produce oil or natural gas 
from these or any other potential drilling locations. 

Our future drilling activities may not be successful.  Our overall drilling success rate or our drilling 

success rate within a particular area may decline.  In addition, we may not be able to obtain any options or lease 
rights in potential drilling locations that we identify.  Although we have identified numerous potential drilling 
locations, we may not be able to economically produce oil or natural gas from all of them. 

Our hedging activities may result in financial losses or may limit the prices that we receive for oil and natural gas 
sales. 

To manage our exposure to price risks in the sale of our oil and natural gas production, we enter into 

commodity price risk management arrangements periodically with respect to a portion of our current or future 
production.  We have hedged a significant portion of anticipated future production from our currently producing 
properties using zero-cost collars and swaps.  As of December 31, 2009, we were in a net accrued liability 
position of approximately $81 million with respect to our oil and natural gas hedging activities.  These activities 
may expose us to the risk of financial loss in certain circumstances, including instances in which: 

  Our production is less than expected 

  One or more counterparties to our hedge contracts default on their contractual obligations 

  There is a widening of price differentials between delivery points for our production and the delivery 

point assumed in the hedge arrangement. 

The risk of one or more counterparties defaulting on their obligations is heightened by the recent global 
and domestic economic and financial downturn affecting many banks and other financial institutions, including 
our counterparties and their affiliates.  These circumstances may adversely affect the ability of our counterparties 
to meet their obligations to us pursuant to hedge transactions, which could reduce our revenues and cash flows 
from realized hedge settlements.  As a result, our financial condition, results of operations, and cash flows could 
be materially adversely affected if our counterparties default on their contractual obligations under our hedge 
contracts. 

In addition, commodity price hedging may limit the prices that we receive for our oil and natural gas sales 

if oil or natural gas prices rise substantially over the price established by the hedge.  Some of our hedging 
transactions use derivative instruments that may involve basis risk.  Basis risk in a hedging contract can occur 
when the change in the index upon which the hedge is based does not correlate well to the change in the index 
upon which the hedged production is valued, thereby making the hedge less effective.  For example, a change in 
31 

 
the NYMEX price used for hedging certain volumes of production may not correlate exactly to the change in the 
regional price used for the sale of that production. 

The inability of one or more of our customers to meet their obligations may adversely affect our financial results. 

Substantially all of our accounts receivable result from oil and natural gas sales or joint interest billings to 

third parties in the energy industry.  This concentration of customers and joint interest owners may impact our 
overall credit risk in that these entities may be similarly affected by various economic and other conditions, 
including the recent global and domestic economic and financial downturn. 

Future oil and natural gas price declines or unsuccessful exploration efforts may result in write-downs of our 
asset carrying values. 

We follow the successful efforts method of accounting for our oil and natural gas properties.  All property 

acquisition costs and costs of exploratory and development wells are capitalized when incurred, pending the 
determination of whether proved reserves have been discovered.  If proved reserves are not discovered with an 
exploratory well, the costs of drilling the well are expensed. 

The capitalized costs of our oil and natural gas properties, on a field basis, cannot exceed the estimated 

undiscounted future net cash flows of that field.  If net capitalized costs exceed undiscounted future net revenues, 
we generally must write down the costs of each such field to the estimated discounted future net cash flows of that 
field.  Unproved properties are evaluated at the lower of cost or fair market value.  As a result of significant oil 
and natural gas price declines in the second half of 2008, we incurred impairment of proved property write-
downs, impairment of unproved properties, and goodwill impairment totaling $302.2 million, $39.0 million, and 
$9.5 million, respectively, during 2008.  In addition, we incurred impairment of proved property write-downs and 
impairment of unproved properties totaling $174.8 million and $45.4 million, respectively, during 2009.  
Significant further declines in oil or natural gas prices in the future or unsuccessful exploration efforts could cause 
further impairment write-downs of capitalized costs. 

We review the carrying value of our properties quarterly based on prices in effect as of the end of each 
quarter.  Once incurred, a write-down of oil and natural gas properties cannot be reversed at a later date, even if 
oil or natural gas prices increase. 

Lower oil or natural gas prices could limit our ability to borrow under our revolving credit facility. 

Our revolving credit facility has a maximum commitment amount of $678 million, subject to a borrowing 

base that the lenders periodically redetermine based on the bank group’s assessment of the value of our oil and 
natural gas properties, which in turn is based in part on oil and natural gas prices.  The current borrowing base 
under our credit facility is $900 million, which was determined as of September 29, 2009.  Declines in oil or 
natural gas prices in the future could limit our borrowing base and reduce our ability to borrow under the credit 
facility.  Additionally, the pending divestitures of non-core properties could result in a reduction of our borrowing 
base. 

Our amount of debt may limit our ability to obtain financing for acquisitions, make us more vulnerable to adverse 
economic conditions, and make it more difficult for us to make payments on our debt. 

As of December 31, 2009, we had $267 million, net of debt discount, of total long-term senior unsecured 

debt outstanding under our 3.50% Senior Convertible Notes due 2027, and $188 million of secured debt 
outstanding under our revolving credit facility.  As of February 16, 2010, we had an outstanding balance of 
$211.0 million drawn against our revolving credit facility, resulting in $467.0 million of available debt capacity 
under our revolving credit facility assuming the borrowing conditions of this facility were met.  Our long-term 
debt represented 32 percent of our total book capitalization as of December 31, 2009. 

32 

 
 
 
Our amount of debt could have important consequences for our operations, including: 

  Making it more difficult for us to obtain additional financing in the future for our operations and 
potential acquisitions, working capital requirements, capital expenditures, debt service, or other 
general corporate requirements 

  Requiring us to dedicate a substantial portion of our cash flows from operations to the repayment of 

our debt and the service of interest costs associated with our debt, rather than to productive 
investments 

  Limiting our operating flexibility due to financial and other restrictive covenants, including 

restrictions on incurring additional debt, making acquisitions, and paying dividends 

  Placing us at a competitive disadvantage compared to our competitors that have less debt 

  Making us more vulnerable in the event of adverse economic or industry conditions or a downturn in 

our business. 

Our ability to make payments on our debt and to refinance our debt and fund planned capital expenditures 

will depend on our ability to generate cash in the future.  This, to a certain extent, is subject to general economic, 
financial, competitive, legislative, regulatory, and other factors that are beyond our control.  If our business does 
not generate sufficient cash flow from operations or future sufficient borrowings are not available to us under our 
revolving credit facility or from other sources, we might not be able to service our debt or fund our other liquidity 
needs.  If we are unable to service our debt, due to inadequate liquidity or otherwise, we may have to delay or 
cancel acquisitions, defer capital expenditures, sell equity securities, sell assets, or restructure or refinance our 
debt.  We might not be able to sell our equity securities, sell our assets, or restructure or refinance our debt on a 
timely basis or on satisfactory terms or at all.  In addition, the terms of our existing or future debt agreements, 
including our existing and future credit agreements, may prohibit us from pursuing any of these alternatives.  The 
indenture for our 3.50% Senior Convertible Notes due 2027 provides that under certain circumstances we have 
the option to settle our obligations under these notes through the issuance of shares of our common stock if we so 
elect. 

Our debt instruments, including our revolving credit facility agreement, also permit us to incur additional 

debt in the future.  In addition, the entities we may acquire in the future could have significant amounts of debt 
outstanding which we could be required to assume in connection with the acquisition, or we may incur our own 
significant indebtedness to consummate an acquisition. 

As discussed above, our revolving credit facility is subject to periodic borrowing base redeterminations.  
We could be forced to repay a portion of our bank borrowings in the event of a downward redetermination of our 
borrowing base, and we may not have sufficient funds to make such repayment at that time.  If we do not have 
sufficient funds and are otherwise unable to negotiate renewals of our borrowing base or arrange new financing, 
we may be forced to sell significant assets. 

We are subject to operating and environmental risks and hazards that could result in substantial losses. 

Oil and natural gas operations are subject to many risks, including well blowouts, craterings, explosions, 

uncontrollable flows of oil, natural gas, or well fluids, fires, adverse weather such as hurricanes in the South 
Texas & Gulf Coast region, freezing conditions, formations with abnormal pressures, pipeline ruptures or spills, 
pollution, releases of toxic gas, and other environmental risks and hazards.  If any of these types of events occurs, 
we could sustain substantial losses. 

Under certain limited circumstances we may be liable for environmental damage caused by previous 

owners or operators of properties that we own, lease, or operate.  As a result, we may incur substantial liabilities 
to third parties or governmental entities, which could reduce or eliminate funds available for exploration, 
development, or acquisitions, or cause us to incur losses. 

33 

 
We maintain insurance against some, but not all, of these potential risks and losses.  We have significant 
but limited coverage for sudden environmental damages.  We do not believe that insurance coverage for the full 
potential liability that could be caused by sudden environmental damages or insurance coverage for environmental 
damage that occurs over time is available at a reasonable cost.  In addition, pollution and environmental risks 
generally are not fully insurable.  Further, we may elect not to obtain other insurance coverage under 
circumstances where we believe that the cost of available insurance is excessive relative to the risks presented.  
Accordingly, we may be subject to liability or may lose substantial portions of certain properties in the event of 
environmental or other damages.  If a significant accident or other event occurs and is not fully covered by 
insurance, we could suffer a material loss. 

Following the severe Atlantic hurricanes in 2004, 2005, and 2008, the insurance markets suffered 
significant losses.  As a result, insurance coverage for wind storms has become substantially more expensive, and 
future availability and costs of coverage are uncertain. 

Our operations are subject to complex laws and regulations, including environmental regulations that result in 
substantial costs and other risks. 

Federal, state, and local authorities extensively regulate the oil and natural gas industry.  Legislation and 

regulations affecting the industry are under constant review for amendment or expansion, raising the possibility of 
changes that may affect, among other things, the pricing or marketing of oil and natural gas production.  
Noncompliance with statutes and regulations may lead to substantial penalties and the overall regulatory burden 
on the industry increases the cost of doing business and, in turn, decreases profitability. 

Governmental authorities regulate various aspects of oil and natural gas drilling and production, including 
the drilling of wells (through permit and bonding requirements), the spacing of wells, the unitization or pooling of 
interests in oil and natural gas properties, environmental matters, safety standards, the sharing of markets, 
production limitations, plugging and abandonment standards, and restoration.  Under certain circumstances, 
federal authorities may require any of our ongoing or planned operations on federal leases to be delayed, 
suspended, or terminated.  Any such delay, suspension, or termination could have a materially adverse effect on 
our operations. 

Our operations are also subject to complex and constantly changing environmental laws and regulations 

adopted by federal, state, and local governmental authorities in jurisdictions where we are engaged in exploration 
or production operations.  New laws or regulations, or changes to current requirements, could result in material 
costs or claims with respect to properties we own or have owned.  We will continue to be subject to uncertainty 
associated with new regulatory interpretations and inconsistent interpretations between state and federal agencies.  
Under existing or future environmental laws and regulations, we could face significant liability to governmental 
authorities and third parties, including joint and several as well as strict liability, for discharges of oil, natural gas, 
or other pollutants into the air, soil, or water, and we could be required to spend substantial amounts on 
investigations, litigation, and remediation.  Existing environmental laws or regulations, as currently interpreted or 
enforced, or as they may be interpreted, enforced, or altered in the future, may have a materially adverse effect on 
us. 

Proposed federal and state legislation and regulatory initiatives relating to hydraulic fracturing could result in 
increased costs and additional operating restrictions or delays. 

The U.S. Congress is currently considering legislation that would amend the Safe Drinking Water Act to 

eliminate an existing exemption from federal regulation of hydraulic fracturing activities and require the 
disclosure of chemical additives used by the oil and gas industry in the hydraulic fracturing process.  Hydraulic 
fracturing is a common process in our industry of creating artificial cracks, or fractures, in deep underground rock 
formations through the pressurized injection of water, sand and other additives to enable oil or natural gas to 
move more easily through the rock pores to a production well.  This process is often necessary to produce 
commercial quantities of oil and natural gas from many reservoirs, especially shale rock formations.  We 
routinely utilize hydraulic fracturing techniques in many of our reservoirs, and our Eagle Ford, Haynesville, 
Marcellus, and Woodford shale programs utilize or contemplate the utilization of hydraulic fracturing.  Currently, 
34 

 
regulation of hydraulic fracturing is primarily conducted at the state level through permitting and other 
compliance requirements.  If adopted, the proposed amendment to the Safe Drinking Water Act could result in 
additional regulations and permitting requirements at the federal level.  In addition, various states are also 
studying or considering various additional regulatory measures related to hydraulic fracturing.  Additional 
regulations and permitting requirements could lead to significant operational delays and increased operating costs, 
and make it more difficult to perform hydraulic fracturing. 

Proposed legislation to eliminate or reduce certain federal income tax incentives and deductions available to oil 
and gas exploration and production companies could, if enacted into law, have a material adverse effect on our 
results of operations and cash flows. 

In 2009, the ―Oil Industry Tax Break Repeal Act of 2009‖ was introduced in the U.S. Senate.  This bill 

proposes amendments to the Internal Revenue Code of 1986 to eliminate or reduce certain federal income tax 
incentives and deductions currently available to oil and gas exploration and production companies.  The proposed 
amendments include the elimination or reduction of current deductions for intangible drilling and development 
costs, percentage depletion allowances, and the manufacturing deduction for oil and gas properties.  President 
Obama’s proposed Fiscal Year 2011 Budget also contemplates these proposed tax law amendments.  If some or 
all of these provisions are enacted into law, our effective tax rate and current income tax expense will increase, 
potentially significantly, which would increase cash requirements to pay income tax thereby reducing cash flows 
from operating activities, which in turn will reduce cash available for drilling and other exploration and 
development activities. 

Enactment of a Pennsylvania severance tax on natural gas could adversely impact the economic viability of 
exploiting natural gas drilling and production opportunities in our Marcellus Shale resource play. 

The Governor of the Commonwealth of Pennsylvania has proposed to its legislature the adoption of a 

severance tax on the production of natural gas in Pennsylvania.  The amount of the proposed tax is five percent of 
the value of the natural gas at the wellhead, plus $0.047 per Mcf of natural gas severed.  Our Marcellus Shale 
acreage is located in Pennsylvania.  If Pennsylvania adopts such a severance tax, it could impact the economic 
viability of exploiting natural gas drilling and production opportunities in the Marcellus Shale. 

Possible legislation and regulations related to global warming and climate change could have an adverse effect 
on our operations and the demand for oil and natural gas. 

On December 15, 2009, the U.S. Environmental Protection Agency (EPA) officially published its 
findings that emissions of carbon dioxide, which is a byproduct of the burning of refined oil products and natural 
gas, methane, which is a primary component of natural gas, and other ―greenhouse gases‖ present an 
endangerment to human health and the environment because emissions of such gases are, according to the EPA, 
contributing to warming of the Earth’s atmosphere and other climatic changes.  These findings by the EPA allow 
the agency to proceed with the adoption and implementation of regulations that would restrict emissions of 
greenhouse gases under existing provisions of the federal Clean Air Act.  In late September 2009, the EPA had 
proposed two sets of regulations in anticipation of finalizing its findings that would require a reduction in 
emissions of greenhouse gases from motor vehicles and that could also lead to the imposition of greenhouse gas 
emission limitations in Clean Air Act permits for certain stationary sources.  In addition, on September 22, 2009, 
the EPA issued a final rule requiring the reporting of greenhouse gas emissions from specified large greenhouse 
gas emission sources in the United States beginning in 2011 for emissions occurring in 2010.  The adoption and 
implementation of any regulations imposing reporting obligations on, or limiting emissions of greenhouse gases 
from, our equipment and operations could require us to incur increased costs to reduce emissions of greenhouse 
gases associated with our operations and could adversely affect demand for the oil and natural gas that we 
produce. 

In addition, on June 26, 2009, the U.S. House of Representatives passed the ―American Clean Energy and 
Security Act of 2009‖ (ACESA), which would establish an economy-wide cap-and-trade program to reduce U.S. 
emissions of greenhouse gases, including carbon dioxide and methane.  ACESA would require a 17% reduction in 

35 

 
greenhouse gas emissions from 2005 levels by 2020, and just over an 80% reduction of such emissions by 2050.  
Under this legislation, the EPA would issue a capped and steadily declining number of tradable emissions 
allowances to certain major sources of greenhouse gas emissions so that such sources could continue to emit 
greenhouse gases into the atmosphere.  The cost of these allowances would be expected to escalate significantly 
over time.  The net effect of ACESA would be to impose increasing costs on the combustion of carbon-based 
fuels such as oil, refined petroleum products, and natural gas.  The U.S. Senate has begun work on its own 
legislation for restricting domestic greenhouse gas emissions, and the Obama administration has indicated its 
support of legislation to reduce greenhouse gas emissions through an emission allowance system.  In addition, 
several states have considered initiatives to regulate emissions of greenhouse gases, primarily through the planned 
development of greenhouse gas emissions inventories and/or regional greenhouse gas cap and trade programs.  
Although it is not possible at this time to predict when the U.S. Senate may act on climate change legislation or 
how any bill passed by the Senate would be reconciled with ACESA, any future federal or state laws or 
regulations that may be adopted to address greenhouse gas emissions could require us to incur increased operating 
costs and could adversely affect the demand for the oil and natural gas that we produce. 

The adoption of derivatives legislation by Congress and related regulations could have an adverse impact on our 
ability to hedge risks associated with our business. 

The U.S. Congress is currently considering legislation to increase the regulatory oversight of the over-the-

counter derivatives markets in order to promote more transparency in those markets, and impose restrictions on 
certain derivatives transactions, which could affect the use of derivatives in hedging transactions.  ACESA 
contains provisions that would prohibit private energy commodity derivative and hedging transactions.  ACESA 
would expand the power of the Commodity Futures Trading Commission (CFTC) to regulate derivative 
transactions related to energy commodities, including oil and natural gas, and to mandate clearance of such 
derivative contracts through registered derivative clearing organizations.  Under ACESA, the CFTC’s expanded 
authority over energy derivatives would terminate upon the adoption of general legislation covering derivative 
regulatory reform.  The Chairman of the CFTC has announced that the CFTC intends to conduct hearings to 
determine whether to set limits on trading and positions in commodities with finite supply, particularly energy 
commodities, such as crude oil, natural gas and other energy products.  The CFTC also is evaluating whether 
position limits should be applied consistently across all markets and participants.  In addition, the Treasury 
Department recently has indicated that it intends to propose legislation to subject all OTC derivative dealers and 
all other major OTC derivative market participants to substantial supervision and regulation, including by 
imposing conservative capital and margin requirements and strong business conduct standards.  Derivative 
contracts that are not cleared through central clearinghouses and exchanges may be subject to substantially higher 
capital and margin requirements.  Although it is not possible at this time to predict whether or when Congress 
may act on derivatives legislation or how any climate change bill approved by the Senate would be reconciled 
with ACESA, any new laws or regulations in this area may result in increased costs and cash collateral 
requirements for the types of oil and gas derivative instruments we use to hedge and otherwise manage our 
financial risks related to swings in oil and gas commodity prices, may impose additional restrictions on our 
trading and commodity positions, and could have an adverse effect on our ability to hedge risks associated with 
our business and on the cost of our hedging activity. 

Our ability to sell oil and natural gas and/or receive market prices for our oil and natural gas production may be 
adversely affected by constraints on pipelines and gathering systems owned by others and various transportation 
interruptions. 

The marketability of our oil and natural gas production depends in part on the availability, proximity, and 

capacity of pipeline transportation and gathering systems owned by third parties.  The lack of available 
transportation capacity on these systems and facilities could result in the shutting-in of producing wells, the delay 
or discontinuance of development plans for properties, or lower price realizations.  Although we have some 
contractual control over the transportation of our production, material changes in these business relationships 
could materially affect our operations.  Federal and state regulation of oil and natural gas production and 
transportation, tax and energy policies, changes in supply and demand, pipeline pressures, damage to or 

36 

 
destruction of pipelines, and general economic conditions could adversely affect our ability to produce, gather, 
and transport oil and natural gas. 

In particular, if drilling in the Eagle Ford, Haynesville, and Marcellus shales continues to be successful, 

the amount of natural gas being produced by us and others could exceed the capacity of the various gathering and 
intrastate or interstate transportation pipelines currently available in these areas.  If this occurs, it will be 
necessary for new pipelines and gathering systems to be built.  Because of the current economic climate, certain 
pipeline projects that are being considered for these areas may not be developed due to lack of financing.  In 
addition, capital constraints could limit our ability to build intrastate gathering systems necessary to transport our 
gas to interstate pipelines.  In such event, we might have to shut in our wells to wait for a pipeline connection or 
capacity and/or sell natural gas production at significantly lower prices than those quoted on NYMEX, which 
would adversely affect our results of operations and cash flows. 

A portion of our natural gas and oil production in any region may be interrupted, or shut in, from time to 

time for numerous reasons, including as a result of weather conditions, accidents, loss of pipeline or gathering 
system access, field labor issues or strikes, or we might voluntarily curtail production in response to market 
conditions.  If a substantial amount of our production is interrupted at the same time, it could temporarily 
adversely affect our cash flows. 

New technologies may cause our current exploration and drilling methods to become obsolete. 

The oil and gas industry is subject to rapid and significant advancements in technology, including the 

introduction of new products and services using new technologies.  As competitors use or develop new 
technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to 
implement new technologies at a substantial cost.  In addition, competitors may have greater financial, technical 
and personnel resources that allow them to enjoy technological advantages and may in the future allow them to 
implement new technologies before we can.  One or more of the technologies that we currently use or that we 
may implement in the future may become obsolete.  We cannot be certain that we will be able to implement 
technologies on a timely basis or at a cost that is acceptable to us.  If we are unable to maintain technological 
advancements consistent with industry standards, our operations and financial condition may be adversely 
affected. 

Risks Related to Our Common Stock 

The price of our common stock may fluctuate significantly, which may result in losses for investors. 

From January 1, 2009 to February 16, 2010, the closing daily sales price of our common stock as reported 

by the New York Stock Exchange ranged from a low of $11.58 per share to a high of $37.89 per share.  We 
expect our stock to continue to be subject to fluctuations as a result of a variety of factors, including factors 
beyond our control.  These factors include: 

  Changes in oil or natural gas prices 

  Variations in quarterly drilling, recompletions, acquisitions, and operating results 

  Changes in financial estimates by securities analysts 

  Changes in market valuations of comparable companies 

  Additions or departures of key personnel 

  Future sales of our common stock 

  Changes in the national and global economic outlook. 

37 

 
We may fail to meet expectations of our stockholders and/or of securities analysts at some time in the 

future, and our stock price could decline as a result. 

Our certificate of incorporation and by-laws have provisions that discourage corporate takeovers and could 
prevent stockholders from receiving a takeover premium on their investment. 

Our certificate of incorporation and by-laws contain provisions that may have the effect of delaying or 

preventing a change of control.  These provisions, among other things, provide for non-cumulative voting in the 
election of members of the Board of Directors and impose procedural requirements on stockholders who wish to 
make nominations for the election of Directors or propose other actions at stockholder meetings.  These 
provisions, alone or in combination with each other and with the shareholder rights plan described below, may 
discourage transactions involving actual or potential changes of control, including transactions that otherwise 
could involve payment of a premium over prevailing market prices to stockholders for their common stock. 

Under our shareholder rights plan, if the Board of Directors determines that the terms of a potential 

acquisition do not reflect the long-term value of St. Mary, the Board of Directors could allow the holder of each 
outstanding share of our common stock, other than those held by the potential acquirer, to purchase one additional 
share of our common stock with a market value of twice the exercise price.  This prospective dilution to a 
potential acquirer would make the acquisition impracticable unless the terms were improved to the satisfaction of 
the Board of Directors.  The existence of the plan may impede a takeover not supported by our Board, even 
though such takeover may be desired by a majority of our stockholders or may involve a premium over the 
prevailing stock price. 

Shares eligible for future sale may cause the market price of our common stock to drop significantly, even if our 
business is doing well. 

The potential for sales of substantial amounts of our common stock in the public market may have a 

materially adverse effect on our stock price.  As of February 16, 2010, 62,590,571 shares of our common stock 
were freely tradable without substantial restriction or the requirement of future registration under the Securities 
Act of 1933.  Also, as of that date, options to purchase 1,271,292 shares of our common stock were outstanding, 
of which all were exercisable.  These options are exercisable at prices ranging from $7.97 to $20.87 per share.  In 
addition, restricted stock units providing for the issuance of up to a total of 403,968 shares of our common stock 
and 1,141,113 performance share awards (―PSAs‖) were outstanding.  The PSAs represent the right to receive, 
upon settlement of the PSAs after the completion of a three-year performance period, a number of shares of our 
common stock that may be from zero to two times the number of PSAs granted, depending on the extent to which 
the underlying performance criteria have been achieved and the extent to which the PSAs have vested.  As of 
February 16, 2010, there were 62,777,688 shares of common stock outstanding, which is net of 126,893 treasury 
shares. 

We may not always pay dividends on our common stock. 

The payment of future dividends remains at the discretion of the Board of Directors, and will continue to 
depend on our earnings, capital requirements, financial condition, and other factors.  In addition, the payment of 
dividends is subject to covenants in our credit facility, including a covenant regarding the level of our current ratio 
of current assets to current liabilities and a limit on the annual dividend rate that we may pay to no more than 
$0.25 per share.  The Board of Directors may determine in the future to reduce the current semi-annual dividend 
rate of $0.05 per share, or discontinue the payment of dividends altogether.

Holders.  As of February 16, 2010, the number of record holders of St. Mary’s common stock was 111.  

Based on inquiry, management believes that the number of beneficial owners of our common stock is 
approximately 17,000. 

Dividends.  St. Mary has paid cash dividends to stockholders every year since 1940.  Annual dividends of 
$0.05 per share were paid in each of the years 1998 through 2004.  Annual dividends of $0.10 per share were paid 
in 2005 through 2009.  We expect that our practice of paying dividends on our common stock will continue, 
although the payment of future dividends will continue to depend on our earnings, cash flow, capital 
requirements, financial condition, and other factors.  In addition, the payment of dividends is subject to covenants 
in our credit facility, including the requirement that we maintain the level of our current ratio of current assets to 
current liabilities and the limitation of our annual dividend rate to no more than $0.25 per share per year.  
Dividends are currently paid on a semi-annual basis.  Dividends paid totaled $6.2 million in 2009 and $6.2 million 
in 2008. 

Equity Incentive Compensation Plan.  In May 2009, the shareholders approved an amendment to rename 

the 2006 Equity Incentive Compensation Plan to the Equity Incentive Compensation Plan (the ―Equity Plan‖).

In May 2006 the stockholders approved the Equity Plan to authorize the issuance of restricted stock, restricted stock units, non-
qualified stock options, incentive stock options, stock appreciation rights, and stock-based awards to key employees, consultants, and 
members of the Board of Directors of St. Mary or any affiliate of St. Mary.  The Equity Plan serves as the successor to the St. Mary 
Land & Exploration Company Stock Option Plan, the St. Mary Land & Exploration Company Incentive Stock Option Plan, the St. 
Mary Land & Exploration Company Restricted Stock Plan, and the St. Mary Land & Exploration Company Non-Employee Director 
Stock Compensation Plan (collectively referred to as the ―Predecessor Plans‖).  All grants of equity are now made out of the Equity 
Plan, and no further grants will be made under the Predecessor Plans.  Each outstanding award under a Predecessor Plan immediately 
prior to the effective date of the Equity Plan continues to be governed solely by the terms and conditions of the instruments evidencing 
such grants or issuances.  Our Board of Directors approved amendments to the Equity Plan on March 26, 2008, and the amended plan 
was approved by stockholders at our annual stockholders’ meeting May 21, 2008.  Our Board of Directors approved additional 
amendments to the Equity Plan on March 26, 2009, and the amendments were approved by stockholders at our annual stockholders’ 
meeting on May 20, 2009.  Awards granted in 2009, 2008, and 2007 under the Equity Plan were 1,016,931, 932,767, and 135,138, 
respectively. 

(2)  Under the St. Mary Land & Exploration Company Employee Stock Purchase Plan (the ―ESPP‖), eligible employees may purchase 

shares of our common stock through payroll deductions of up to 15 percent of their eligible compensation.  The purchase price of the 
stock is 85 percent of the lower of the fair market value of the stock on the first or last day of the six-month offering period, and shares 
issued under the ESPP through December 31, 2009, are restricted for a period of 18 months from the date issued.  Effective 
January 1, 2010, shares issued under the ESPP will be restricted for a period six months from the date issued.  The ESPP is intended to 
qualify under Section 423 of the Internal Revenue Code.  Shares issued under the ESPP totaled 86,308, 45,228, and 29,534 in 2009, 
2008, and 2007, respectively. 

(3)  The PSAs represent the right to receive, upon settlement of the PSAs after the completion of a three-year performance measurement 
period, a number of shares of our common stock that may be from zero to two times the number of PSAs granted, depending on the 
extent to which the underlying performance criteria have been achieved and the extent to which the PSAs have vested.  The 
performance criteria for the PSAs are based on a combination of our cumulative Total Shareholder Return (―TSR‖) for the 
performance period and the relative measure of our TSR compared with the TSR an index comprised of certain peer companies for the 
performance period.  The current outstanding PSAs were granted on August 1, 2009, and 2008, and utilize a three-year performance 
measurement period which began on July 1, 2009, and 2008, respectively. On July 1, 2009, the market value per share of our common

stock was $21.15, and on the date of grant the market value per share of our common stock was $23.87.  On July 1, 2008, the market 
value per share of our common stock was $62.51, and on the date of grant the market value per share of our common stock was 
$43.11.  The PSAs do not have an exercise price associated with them, but rather the $32.52 price shown in the above table represents 
the weighted-average per share fair value as of December 31, 2009, calculated pursuant to ASC Topic 718, which is presented in order 
to provide additional information regarding the potential dilutive effect of the PSAs as of December 31, 2009, in view of the share 
price level at the beginning of the performance period which will be utilized to compute the TSR measurements for determination of 
the number of shares to be issued upon settlement of the PSAs after completion of the three-year performance measurement period.

authorization to repurchase 3,072,184 shares of common stock on a prospective basis.  The shares may be repurchased from time to 
time in open market transactions or privately negotiated transactions, subject to market conditions and other factors, including certain 
provisions of St. Mary’s existing bank credit facility agreement and compliance with securities laws.  Stock repurchases may be 
funded with existing cash balances, internal cash flow, and borrowings under St. Mary’s bank credit facility. The stock repurchase 
program may be suspended or discontinued at any time. 

The payment of dividends and stock repurchases are subject to covenants in our bank credit facility, including the requirement that we 
maintain certain levels of stockholders’ equity and the limitation that does not allow our annual dividend rate to exceed $0.25 per 
share.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS 

This discussion includes forward-looking statements.  Please refer to ―Cautionary Information about 

Forward-Looking Statements‖ in Part I, Items 1 and 2 of this Form 10-K for important information about these 
types of statements. 

Overview of the Company 

General Overview 

We are an independent energy company focused on the development, exploration, exploitation, 
acquisition, and production of natural gas and crude oil in North America.  We generate nearly all our revenues 
and cash flows from the sale of produced natural gas and crude oil.  Our oil and gas reserves and operations are 
concentrated primarily in the Rocky Mountain Williston Basin; the Mid-Continent Anadarko and Arkoma basins; 
the Permian Basin; the productive formations of East Texas and North Louisiana; north central Pennsylvania; the 
Maverick Basin in South Texas; and the onshore Gulf Coast and offshore Gulf of Mexico.  We have developed a 
balanced and diverse portfolio of proved reserves, development drilling opportunities, and unconventional 
resource prospects. 

Our mission is to deliver outstanding net asset value per share growth to our investors via attractive oil 

and gas investments.  Historically, we have relied on a strategy of growing through niche acquisitions focused in 
the continental United States.  Over the last few years, we have shifted our strategy to focus more on capturing 
potential resource plays earlier and at a lower cost.  We believe that this shift will allow for more stable and 
predictable production and proved reserves growth.  Going forward, we will focus on continuing to acquire 
significant leasehold positions in existing and emerging resource plays in North America. 

In 2009 we had the following financial and operational results: 

  Average daily gas production of 194.8 MMcf was down five percent from 2008.  Average daily oil 

production of 17.3 MBbl was down four percent from 2008.  Average total equivalent daily 
production was 298.8 MMCFE, which was down five percent from 2008. 

  Estimated proved reserves of 53.8 MMBbls of oil and 449.5 Bcf of natural gas, or 772.2 BCFE, as of 

December 31, 2009.  This was a decrease of 11 percent from year-end 2008 proved reserves of 
865.5 BCFE and reflects the divestiture of 44.2 BCFE of non-strategic properties, 61.6 BCFE in net 
downward performance revisions, and 12.0 BCFE of net positive price revisions.  We had reserve 
additions from extensions and discoveries and infill drilling of 109.6 BCFE. 

  We recorded a net loss of $99.4 million and diluted loss per share of $1.59 for the year ended 

December 31, 2009.  This compares with net income of $87.3 million, or $1.38 per diluted share, for 
the year ended December 31, 2008. 

  Cash flow from operating activities of $436.1 million, a decrease of 36 percent from 2008. 

  Costs incurred for oil and gas producing activities for the year ended December 31, 2009, were 

$419.0 million, compared with $857.7 million for the same period in 2008. 

Our operations are generally funded first through cash flows from operating activities and then through 

borrowings under our existing credit facility.  The divestiture of non-core assets is also a potential source of 
liquidity.  Acquisitions may be funded with proceeds from sales of public or private debt and equity, borrowings 
under our existing facility, property sales, and cash flow from operating activities.  In 2009 we invested 
$377.2 million for development and exploration and $41.7 million for leasehold. 

50 

 
A major determination of the value of our company is the value of our proved reserves.  At year-end 2009 
we had proved reserves of 772.2 BCFE of which 58 percent were natural gas and 82 percent were characterized as 
proved developed.  There were a number of changes that took effect in 2009 impacting the calculation of our 
year-end proved reserves.  The SEC instituted a number of revisions to its existing oil and gas reporting 
requirements.  A key revision to the rules pertains to the use of 12-month average pricing as opposed to year-end 
pricing in estimating proved reserves.  The prices used in the calculation of proved reserve estimates as of 
December 31, 2009, were $61.18 per Bbl and $3.87 per MMBTU for oil and natural gas, respectively.  These 
prices were 23 percent and 33 percent lower, respectively, than the year-end prices that would have been used 
under the SEC’s previous methodology.  Additional changes in the SEC rules provide for the use of new 
technology to determine proved reserves and the ability to include nontraditional resources in proved reserves.  In 
addition to these regulatory changes, in 2009 we began recording estimates of proved reserve volumes for 
properties we believe are reasonably certain to generate positive net cash flows on an undiscounted basis, which 
we have the intent to drill, and which meet our internal economic criteria for drilling even though they may have a 
negative PV-10 value.  Previously, we booked proved reserve volumes if the properties showed a positive PV-10 
value, we had the intent to drill, and the wells met our economic criteria. 

We added 109.6 BCFE from our drilling program during the year, with our emerging resource play in the 
Eagle Ford shale in the Maverick Basin in South Texas contributing a significant portion of those additions.  Our 
programs targeting the Woodford shale in eastern Oklahoma and the Bakken/Three Forks formations in the North 
Dakota portion of the Williston Basin also added meaningful additions in 2009.  We sold 44.2 BCFE of proved 
reserves during the year, with roughly 90 percent of those relating to the divestiture of our coalbed methane 
project at Hanging Woman Basin along the border of Montana and Wyoming.  The balance of the divested 
properties sold in 2009 was non-strategic assets, which were spread across the company. We had a downward net 
revision of 49.6 BCFE that consisted of 61.6 BCFE in net downward engineering revisions and a net positive 
pricing revision of 12.0 BCFE.  The largest portion of the performance revision relates to producing properties in 
our Wolfberry tight oil program in the Permian Basin in West Texas.  Well performance data collected during 
2009 for Wolfberry assets at Sweetie Peck and Halff East indicated these assets are underperforming our year-end 
2008 decline forecasts.  Accordingly, we removed roughly 37 BCFE from proved reserves in the Permian region, 
primarily related to the Wolfberry tight oil program.  We believe that a significant portion of these reserves, while 
not meeting the criteria to be booked as proved reserves at year-end, are likely to be produced eventually.  We 
also saw a downward performance revision of approximately 12 BCFE related to certain Cotton Valley assets in 
our ArkLaTex region.  Due to the pricing methodology changes noted above, we recognized positive price 
revisions in our oil-weighted Rocky Mountain and Permian regions that offset negative price revisions we 
recognized in the natural gas weighted Mid-Continent, ArkLaTex, and South Texas & Gulf Coast regions.  Under 
the previous methodology of using year-end pricing for the determination of proved reserves, we would have had 
an increase of four percent in proved reserves to approximately 897 BCFE. 

The PV-10 value of our proved reserves was $1.3 billion as of December 31, 2009.  The after tax value of 

$1.0 billion as represented by the standardized measure calculation is presented in Note 16 – Disclosures about 
Oil and Gas Producing Activities of Part IV, Item 15 of this report.  A reconciliation between these two amounts 
is shown under Reserves in Part I, Items 1 and 2 of this report.

Reserve Replacement, Finding Costs, and Growth 

Like all oil and gas exploration and production companies, we face the challenge of growing oil and 

natural gas reserves.  An exploration and production company depletes part of its asset base with each unit of oil 
or gas it produces.  Our future growth will depend on our ability to economically add reserves in excess of 
production.

Our challenge is to grow net asset value per share, which we believe drives appreciation in our stock price 
over the long term.  To accomplish this, we believe it is important to economically replace annual production with 
new reserves.  We believe annual reserve replacement percentage and finding cost amounts are important 
analytical measures that are widely used by investors and industry peers in evaluating and comparing the 
performance of oil and gas companies.  While single-year measurements have some meaning in terms of a trend, 
we believe that aberrations, causing both relatively good and bad results, will occur over short intervals of time.  
The information used to calculate the above reserve replacement and finding cost metrics is included in Note 15 – 
Oil and Gas Activities and Note 16 – Disclosures about Oil and Gas Producing Activities of the Notes to 
Consolidated Financial Statements included in part IV, Item 15 of this report.  For additional information about 
these metrics, see the reserve replacement and finding cost terms in the Glossary at the end of Part I, Items 1 and 
2 of this report.

During and subsequent to the third quarter of 2008, specific issues related to the financial sector rippled 
through the broader economy.  The failure or takeovers of several large financial institutions adversely impacted 
the wider equity, debt, and credit markets.  Financial strength and liquidity became increasingly important as 
investors considered the ability of companies to fund their planned levels of activity and to service their debt 
obligations.  In addition, fears of prolonged weakness in the global economy leading to anemic energy demand 
resulted in a significant decline in oil and natural gas prices.  As a result of these events, we entered 2009 with a 
business plan designed to operate within our operating cash flow.  We have maintained a disciplined approach 
with our capital investments during the year, which, combined with higher operating cash flows than we 
anticipated originally, have allowed us to maintain our strong financial position and reduce borrowings under our 
credit facility.  Our exploration and development program at the beginning of 2009 was designed to stay within 
generated cash flow.  We met this goal in 2009.  We continue to believe we have adequate liquidity available to 
us through our credit facility as discussed below under the caption Overview of Liquidity and Capital Resources. 

Oil and Gas Prices 

Our financial condition and the results of our operations are significantly affected by oil and natural gas 
commodity prices, which can fluctuate dramatically.  We sell a majority of our natural gas under contracts that 
use first of the month index pricing, which means that gas produced in a given month is sold at the first of the 
month price regardless of the spot price on the day the gas is produced.  Our crude oil is sold using contracts that 
pay us either the average of the NYMEX West Texas Intermediate daily settlement or the average of alternative 
posted prices for the periods in which the crude oil is produced, adjusted for quality, transportation, and location 
differentials.  The following table is a summary of commodity price data for the years ended December 31, 2009, 
2008, and 2007.

We expect future prices for oil and natural gas to be volatile.  The comparative strength of the U.S. Dollar 

will likely continue to impact crude prices just as changes in domestic industrial demand will continue to impact 
the price of natural gas.  The 12-month strip prices for NYMEX WTI crude and NYMEX Henry Hub gas as of 
December 31, 2009, were $82.15 per Bbl and $5.87 per MMBTU, respectively; comparable prices as of February 
16, 2010, were $79.43 per Bbl and $5.76 per MMBTU, respectively. 

While changes in quoted NYMEX oil and natural gas prices are generally used as a basis for comparison 

within our industry, the price we receive for oil and natural gas is affected by quality, energy content, location, 
and transportation differentials for these products.  We refer to this price as our realized price, which excludes the 
effects of hedging.  Our realized price is further impacted by the results of our hedging arrangements that are 
settled in the respective periods.  We refer to this price as our net realized price.  For the year ended December 31, 
2009, our net natural gas price realization was positively impacted by $125.9 million of realized hedge 
settlements and our net oil price realization was positively impacted by $14.8 million of realized hedge 
settlements.

Hedging Activities 

Hedging is an important part of our financial risk management program.  We have a Board-authorized 
financial risk management policy that governs our practices related to hedging.  The amount of production we 
hedge is driven by the amount of debt on our consolidated balance sheet and the level of capital commitments and 
long-term obligations we have in place.  In the case of a significant acquisition of producing properties, we will 
consider hedging a portion of the acquired production in order to protect the economics assumed in the 
acquisition.  With the hedges we have in place, we believe we have established a base cash flow stream for our 
future operations, and our use of collars for a portion of the hedges allows us to participate in upward movements 
in oil and gas prices while also setting a price floor for a portion of our production.  Please see Note 10 – 
Derivative Financial Instruments of Part IV, Item 15 of this report for additional information regarding our oil and 
gas hedges, and see the caption, Summary of Oil and Gas Production Hedges in Place, later in this section. 

We attempt to qualify our oil and gas derivative instruments as cash flow hedges for accounting purposes 

under Accounting Standards Codification Topic 815.  Changes in the value of our hedge positions are primarily 
reflected in our consolidated balance sheets.  A portion of the change in the value of our hedge positions is 
recognized in our consolidated statements of operations due to the hedges being partially ineffective.  We 
recognized a $20.5 million in non-cash derivative loss for the year ended December 31, 2009. 

The U.S. Congress is currently considering recent proposals to increase the regulatory oversight of the 

over-the-counter derivatives markets in order to promote more transparency in those markets.  Although we 
cannot predict the ultimate outcome of these proposals, new regulations in this area may result in increased costs 
and cash collateral requirements for the types of oil and gas derivative instruments we use to hedge and otherwise 
manage our financial risks related to swings in oil and gas commodity prices. 

2009 Highlights 

Developments in emerging resource plays.  During 2008, the Haynesville shale, the Eagle Ford shale, and 

the Marcellus shale resource plays emerged as significant new sources of gas supply for the exploration and 
production industry.  We have exposure to each of these plays that, if successful, could provide for significant 
future organic growth in reserves and production.  The Haynesville shale emerged early in 2008 in northern 
Louisiana and eastern Texas and quickly became the most active resource play in the country.  Our position was 
built as a result of prior leasing activity targeting the James Lime and Cotton Valley formations.  Our Eagle Ford 
shale position in the Maverick Basin in South Texas was built from 2007 through 2009 through a combination of 
property acquisitions, leasing activity, and participation in a joint venture with industry partners.  Late in 2008 we 
entered into arrangements that allow us to earn or purchase acreage in the Marcellus shale in north central 
Pennsylvania.  During 2009 we worked to advance our understanding of these plays and move them closer to 
development mode.  The most progress was made in our Eagle Ford shale program in South Texas.  We 
successfully tested seven wells across our operated acreage position during the second half of 2009.  The early 
results from this program suggest wells at the southern end of our acreage will produce drier gas while wells 
drilled further north will produce higher BTU-content gas and some condensate.  We are currently booking only 
the parallel offsets to producing wells as proved undeveloped locations.  As a result, we believe meaningful 
potential exists to grow proved reserves on our operated acreage with our planned drilling activity for 2010 and 
increased understanding of how reliable technology will allow the play to be developed.  On our joint venture 
acreage in Dimmit County, Texas, we believe these wells will produce even higher amounts of condensate and oil 
compared to our operated position.  In the Haynesville shale program in the ArkLaTex region, a number of 
successful wells were drilled around our acreage position in East Texas in 2009.  We began horizontal drilling 
early in 2010 when our 3D seismic analysis was completed.  In our Marcellus shale program in north central 
Pennsylvania, we drilled and completed our first two horizontal wells during 2009.  Initial indications from the 
well tests were encouraging.  The gathering line that will connect these wells to sales is in the process of being 
constructed. 

Shift toward oil-weighted projects.  As a result of continued downward pressure on natural gas prices and 
an increase in oil prices, we began shifting capital investment dollars toward oil-weighted projects during the third 

54 

 
quarter.  We saw an increase in activity in our Permian and Rocky Mountain regions as a result of this shift in 
capital. 

Borrowing base on credit facility maintained.  On September 29, 2009, the borrowing base on our credit 

facility was redetermined and maintained by our bank group at a value of $900 million. 

Impairments.  We recognized a pre-tax non-cash impairment of proved properties in the amount of $174.8 

million in 2009.  There was an impairment of proved properties in the amount of $302.2 million in 2008.  A 
significant decrease in the market price for natural gas, including differentials in effect at March 31, 2009, caused 
the majority of the non-cash impairment.  The largest portion of the change in 2009 was $97.3 million related to 
assets located in the Mid-Continent region which were impacted by the lower March 31, 2009, prices referred to 
above as well as wider than normal differentials.  The ArkLaTex region was impacted by a $20.4 million 
impairment related to downward pricing and engineering revisions.  We incurred a $14.0 million impairment on 
proved properties related to the write-down of certain assets located in the Gulf of Mexico for which we are 
relinquishing our ownership interests. 

During the year, we abandoned or impaired $45.4 million related to unproved properties.  The largest 

specific components of the 2009 impairment and abandonment related to the Floyd Shale acreage located in 
Mississippi and acreage in Oklahoma.  The remaining write-offs were related to acreage we believe we will not be 
able to hold due to current allocations of capital and to acreage that we do not believe will be prospective. 

Lastly, we incurred inventory write-downs of $14.2 million for the year ended December 31, 2009 in 
order to present inventory at the lower of cost or market value.  The market value of tubular goods and other 
inventory items that were purchased in 2008 when prices for these goods were considerably higher declined over 
the course of 2009 as a result of lower levels of activity throughout the industry. 

Divestitures.  We continue to optimize our portfolio of assets as part of our overall strategy to focus on 

concentrated resource plays.  As part of this strategy, on December 18, 2009, we completed the divestiture of our 
non-strategic coalbed methane project at Hanging Woman Basin located in the Rocky Mountain region.  Total 
cash received was $23.3 million, which is subject to customary post-closing adjustments.  During 2009 we 
recorded an $11.4 million gain on divestiture activity, which included the gain from the Hanging Woman Basin 
divestiture, as well as other smaller divestitures.

In 2009 our production and oil and gas production revenues have outperformed our initial budget for 2009 

due to stronger than anticipated production results from our Mid-Continent and Permian regions.  Please refer to

production.

Net Profits Plan.  For the year ended December 31, 2009, the change in the value of this liability resulted 

in a non-cash benefit of $7.1 million compared with a $34.0 million benefit for the same period in 2008.  
Decreases in oil and gas commodity prices have decreased the estimated liability for the future amounts to be paid 
to plan participants.  This liability is a significant management estimate.  Adjustments to the liability are subject 
to estimation and may change dramatically from period to period based on assumptions used for production rates, 
reserve quantities, commodity pricing, discount rates, tax rates, and production costs. 

Payments made from the Net Profits Plan have been expensed as compensation costs in the amounts of 

$19.9 million, $36.3 million, and $31.9 million for the years ended December 31, 2009, 2008, and 2007, 
respectively.  Additionally, we accrued cash payments under the Net Profits Plan of $724,000 for the year ended 
December 31, 2009, as a result of sales proceeds during the fourth quarter of 2009.  For the year ended 
December 31, 2008, we accrued for cash payments under the Net Profits Plan of $15.1 million as a result of sales 
proceeds from the Abraxas and Greater Green River Basin divestitures.  These cash payments are accounted for as a 
reduction in the gain (loss) on divestiture activity in the accompanying consolidated statements of operations.  There 
were no significant cash payments made or accrued for under the Net Profits Plan as a result of divestitures during 
2007. 

The recurring cash payments we make are dependent on actual production, realized prices, and operating 
and capital costs associated with the properties in each individual pool.  Actual cash payments will be inherently 
different from the estimated liability amounts.  More detailed discussion is included in the analysis in the 
Comparison of Financial Results and Trends sections below and in Note 11 – Fair Value Measurements in Part 
IV, Item 15.  An increasing percentage of the costs associated with the payments from the Net Profits Plan are 
now being categorized as general and administrative expense as compared to exploration expense.  This is a 
function of the normal departure of employees who previously contributed to our exploration efforts.  In 
December 2007, our Board approved an incentive compensation plan restructuring, whereby the Net Profits Plan 
was replaced with a long-term incentive program utilizing equity awards.  As a result, the 2007 Net Profits Plan 
pool was the last pool established. 

The calculation of the estimated liability for the Net Profits Plan is highly sensitive to our price estimates 

and discount rate assumptions.  For example, if we changed the commodity prices in our calculation by five 
percent, the liability recorded on the balance sheet at December 31, 2009, would differ by approximately 
$14 million.  A one percentage point decrease in the discount rate would result in an increase to the liability of 
approximately $9 million, while a one percentage point increase in the discount rate would result in a decrease to 
the liability of approximately $8 million.  We frequently re-evaluate the assumptions used in our calculations and 
consider the possible impacts stemming from the current market environment including current and future oil and 
gas prices, discount rates, and overall market conditions.  In 2009 we made adjustments to the discount rate used 
for Net Profits Plan pools not in payout.  Additionally, we changed the price assumption used for estimating the 
liability from a 36-month combination of historical and future prices to one using NYMEX strip prices at the end 
of the respective period. 

Outlook for 2010 

The general economic outlook for the country has improved compared to this time a year ago.  We 
successfully weathered a tough 2009, and in the process advanced a number of potential resource plays and 
improved our financial condition. 

As we enter 2010, we are well positioned both financially and operationally.  Early in 2009, we extended 

the maturity of our revolving credit facility and subsequently paid down outstanding borrowings on that facility 
during the year.  At the end of 2009, we had almost $500 million available under the revolving credit facility.  We 
have no debt maturities until 2012.  Additionally, we believe access to the capital markets has improved 
significantly since last year and that we could access capital through the public markets if necessary.  From an 
operational standpoint, we believe 2010 has the potential to be a promising year for us.  We will be building upon 
our successful testing programs from 2009.  We have moved the Eagle Ford shale program much closer to 
development mode, and it will receive the largest portion of our capital budget this year.  We will also be 
allocating more capital toward oil and rich natural gas projects given their higher returns in the current 

56 

 
environment.  Specifically, we will be drilling more Wolfberry tight oil and Bakken/Three Forks wells in the 
Permian and Rocky Mountain regions, respectively.  We recently began drilling horizontal wells in the 
Haynesville shale.  We continue to monitor service costs as the recent uptick in industry activity threatens to push 
rates for the drilling and completion of wells higher than the levels we saw in 2009.

Financial Results of Operations and Additional Comparative Data 

We recorded a net loss for the year ended December 31, 2009 of $99.4 million or $(1.59) per diluted 

share compared to 2008 results of net income of $87.3 million or $1.38 per diluted share.

Changes in production volumes, oil and gas production revenues, and costs reflect the cyclical and highly 

volatile nature of our industry.  As a result of the effects of lower commodity prices, we have seen reduced 
activity among many exploration and production companies over the past year which has led to lower lease 
operating costs over the last two quarters.  We believe that industry activity may be stabilizing to a point where 
these costs no longer have much room to decline further.  Production taxes are largely dependent on the prices we 
receive for oil and natural gas.  Depreciation, depletion, and amortization generally had been pressured upward in 
recent years as production related to properties acquired or developed in a higher cost environment became a 
larger percentage of our production mix.  During 2009, we have seen our DD&A rate fluctuate as a result of 
impairments and changes to our underlying proved reserve volumes, both of which have been affected by the 
swings in commodity prices we have seen this year.  Additionally, the accounting treatment for assets that are 
classified as assets held for sale also impacted our DD&A rate since properties held for sale are no longer 
depreciated.  A portion of our general and administrative expense is tied to the net revenues we generate, which 
are driven in large part by the realized commodity prices we receive for our production.  The Net Profits Plan and 
a portion of our current short-term incentive compensation are tied to net revenues and therefore are subject to 
variability.

We present per MCFE information because we use this information to evaluate our performance relative 

to our peers and to identify and measure trends we believe require analysis.  Volatility in commodity prices has 
impacted our operating margins.  The decrease in our equivalent realized price for production has corresponded 
with the significant downward move in commodity prices over the last year.  While our cost structure has 
improved over the past year, it has not moved to the same degree.  Our operating profit of $4.35 per MCFE for the 
year ended December 31, 2009, decreased 38 percent from the $7.06 per MCFE we realized for the comparable 
period in 2008. 

Average daily production for the year ended December 31, 2009, decreased to 298.8 MMCFE compared 

with 313.1 MMCFE for the same period in 2008.  For the year ended December 31, 2009, our average net 
realized price decreased by $3.17 per MCFE to $6.94 per MCFE from the same period in 2008.  Lower 
commodity prices were the principal driver of the decrease in 2009.  Unit costs decreased for the year ended 
December 31, 2009, as lease operating expense decreased $0.13 per MCFE to $1.33 per MCFE and production 
taxes decreased $0.34 per MCFE to $0.37 per MCFE.  Production taxes are highly correlated to commodity 
prices, and a portion of our general and administrative expense is linked to our profitability and cash flow.  
Transportation costs remained steady at $0.19 per MCFE for the years ended December 31, 2009, and 2008. 

For the year ended December 31, 2009, depletion, depreciation, amortization, and asset retirement 

obligation accretion expense, increased $0.05 per MCFE to $2.79 per MCFE compared with the same period in 
2008.  The depletion, depreciation, and amortization increase is a result of a decrease in proved reserves used to 
calculate DD&A in the first quarter of 2009, please refer to additional DD&A discussion above.  Exploration 
expense for the year ended December 31, 2009, was $62.2 million, which was four percent higher than the 
$60.1 million incurred during the comparable period in 2008.  Geological and geophysical expense increased $6.0 
million due to an increase in the amount spent for seismic analysis.  Exploratory dry hole expense increased $1.0 
million.  These increases were offset by a $4.9 million decrease in exploration overhead due to a decrease in Net 
Profits Plan payments resulting from decreased oil and gas commodity prices. 

Proved reserves decreased 11 percent to 772.2 BCFE at December 31, 2009, from 865.5 BCFE at 
December 31, 2008.  Please see Note 16 – Disclosures about Oil and Gas Producing Activities of Part IV, Item 15 
of this report and the above discussion under the caption General Overview for additional details and discussion 
on the individual components of the change.  Over time, our ability to economically replace volumes produced 
annually has proven to be a key factor that determines whether we are successful in achieving our goal of 
increasing net asset value per share.  The measure of our success will vary year-to-year due to changes in these 
factors.

We present this table as a summary of information relating to key indicators of financial condition and 

operating performance that we believe are important. 

We account for our 3.50% Senior Convertible Notes under the treasury stock method.  There is no impact 

on the diluted share calculation for the periods presented since our average stock price for the relevant reporting 
periods has not exceeded the conversion price.  The 3.50% Senior Convertible Notes were issued April 4, 2007, 
and have not been dilutive for a reporting period since their issuance.  We have in-the-money stock options, 
unvested RSUs, and PSAs that may be potentially dilutive securities.  Both basic and diluted earnings per share 
are presented in the table above.  There were no potentially dilutive shares related to in-the-money stock options, 
unvested RSUs, and PSAs included in the diluted earnings per share calculation for the year ended 
December 31, 2009, as we recorded a net loss for the period.  A detailed explanation is presented under the 
caption Earnings per Share included in Note 1 – Summary of Significant Accounting Policies, in Part IV, Item 15 
of this report. 

Basic and diluted weighted-average common shares outstanding used in our 2009, 2008, and 2007 

earnings per share calculations reflect our stock repurchases, offset by increases in outstanding shares related to 
stock option exercises, ESPP shares issued, and vested RSUs.  We issued 189,740 shares of common stock in 
2009, 868,372 shares in 2008, and 733,650 shares in 2007 as a result of stock option exercises.  These share 
issuances were offset by the repurchase of 2,135,600 shares of common stock in 2008, and 792,216 shares in 
2007 through our stock repurchase plan.  Additionally, the number of RSUs that vested in 2009, 2008, and 2007 
were 211,092, 291,659, and 268,123, respectively.

Comparison of Financial Results and Trends between 2009 and 2008 

Oil and gas production revenue.  Production decreased five percent to 109.1 BCFE for the year ended 

December 31, 2009, compared with 114.6 BCFE for the year ended December 31, 2008.  Production for the year 
ended December 31, 2009, includes approximately 5.1 BCFE related to non-core properties divested throughout 
2009.    Adjusting for divestitures of non-core properties that were sold in the last two years, production on 
retained properties declined slightly from 104.5 BCFE in 2008 to 104.0 BCFE in 2009.  The following table 
presents the regional changes in our production and oil and gas revenues and costs between the two years:

Daily production decreased by approximately 14.3 MMCFE during 2009 compared to 2008.  Production 
decreased between these two periods as a result of decreased levels of capital investment throughout 2009 and the 
lack of contribution in 2009 from properties that were sold in the second half of 2008.  The largest regional

increase between 2009 and 2008 occurred in the Mid-Continent region as a result of success in the horizontal 
Woodford shale program in the Arkoma Basin and strong results from our Deep Springer program in the 
Anadarko Basin.  Production growth in the Permian region is the result of continued development of Wolfberry 
assets at Sweetie Peck and Halff East.  The decrease in the South Texas & Gulf Coast region’s production is 
primarily a result of the loss of production from the Judge Digby Field due to an exchange of assets that occurred 
in late 2008.  The ArkLaTex decrease is due to natural decline and decreased levels of capital investment in the 
region by us and our partners, particularly at the Elm Grove Field.  The Rocky Mountain region realized a slight 
decline as a result of its more mature production decline profile and modest capital investment. 

Realized oil and gas hedge gain (loss).  We recorded a net realized hedge gain of $140.6 million for the 

year ended December 31, 2009, mainly related to favorable settlements on gas hedges.  For the year ended 
December 31, 2008, we recorded a net realized hedge loss of $101.1 million mainly due to unfavorable 
settlements on oil hedges.  Please refer to our discussion above under the heading Oil and Gas Prices. 

Marketed gas system revenue and expense.  Marketed gas system revenue decreased $18.9 million to 

$58.5 million for the year ended December 31, 2009, compared with $77.4 million for the comparable period of 
2008.  Concurrent with the decrease in marketed gas system revenue, marketed gas system expense decreased 
$14.6 million to $57.6 million for the year ended December 31, 2009, compared with $72.2 million for the 
comparable period of 2008.  We expect that marketed gas system revenue and expense will continue to trend with 
increases and decreases in production and our price realizations before the impact of hedging. 

Gain (loss) on divestiture activity.  We recorded a gain on divestiture activity of $11.4 million for the year 

ended December 31, 2009, compared with $63.6 million for the comparable period of 2008.  The 2009 gain is 
mainly related to the Hanging Woman Basin divestiture that closed in December of 2009, which is subject to 
normal post-closing adjustments and is expected to be finalized during the first quarter of 2010.  The 2008 gain is 
mainly related to the Abraxas divestiture that closed in January 2008.  We expect to continue to evaluate potential 
divestitures of non-strategic properties. 

Oil and gas production expense.  Total production costs decreased $64.6 million or 24 percent to 
$206.8 million for the year ended December 31, 2009, compared with $271.4 million in 2008.  Total oil and gas 
production costs per MCFE decreased $0.47 to $1.89 for the year ended December 31, 2009, compared with 
$2.36 in 2008.  This decrease is comprised of the following: 

  A $0.34 decrease in production taxes on a per MCFE basis due to the decrease in realized prices 

between periods.  We expect production taxes to trend with commodity prices. 

  A $0.11 decrease in recurring lease operating expense on a per MCFE basis is related to reductions in 
recurring LOE that stems from the slowdown in activity in the exploration and production industry, as 
well as the broader economy. 

  A $0.02 decrease in overall workover LOE on a per MCFE basis is related to a reduction in the 
amount of workovers that were performed given the slowdown in activity in the exploration and 
production industry. 

  Transportation costs on a per MCFE basis remained flat year over year.  

Depletion, depreciation, amortization, and asset retirement obligation liability accretion.  DD&A 

decreased $10.1 million, or three percent, to $304.2 million in 2009 compared with $314.3 million in 2008.  
DD&A expense per MCFE increased two percent to $2.79 in 2009 compared to $2.74 in 2008.  The decrease in 
absolute DD&A reflects lower total production volumes in 2009 compared to 2008.  Our DD&A expense per 
MCFE decreased due to the significant decrease in our carrying value of our properties as a result of proved 
property impairments that we incurred in the fourth quarter of 2008 and the first quarter of 2009.  Proved property 
impairments and changes in underlying proved reserve volumes will continue to be affected by the swings in 
commodity prices. 

63 

 
Exploration.  Exploration expense increased $2.1 million or four percent to $62.2 million in 2009 

compared with $60.1 million for 2008.  The increase is due to a $1.0 million increase in exploratory dry hole 
expense and a $6.0 million increase in geological and geophysical expense due to an increase in the amount spent 
on seismic.  We anticipate that we will continue to acquire seismic data into 2010 in order to minimize risk with 
respect to the acreage in our emerging resource plays with the expectation that we can optimize their future 
development.  These increases were offset by a $4.9 million decrease in exploration overhead expense due to a 
decrease in Net Profits Plan payments as a result of decreased oil and gas commodity prices.  We expect 
payments made under the Net Profits Plan to trend with commodity prices. 

Impairment of proved properties.  We recorded a $174.8 million impairment of proved oil and gas 

properties in 2009 compared to $302.2 million in 2008.  A significant decrease in commodity prices, including 
differentials, during the first quarter of 2009 caused the majority of the non-cash impairment.  The largest portion 
of the impairment in 2009 was $97.3 million related to assets located in the Mid-Continent region which were 
impacted at the end of the first quarter by low natural gas prices and wider than normal differentials.  The 
ArkLaTex region was impacted by a $20.4 million impairment related to negative pricing and engineering 
revisions.  We incurred a $14.0 million impairment on proved properties related to the write-down of certain 
assets located in the Gulf of Mexico in which we are relinquishing our ownership interests.  We generally expect 
proved property impairments will be more likely to occur in periods of low commodity prices. 

Abandonment and impairment of unproved properties.  During 2009, we abandoned or impaired 
$45.4 million of unproved properties compared with $39.0 million for 2008.  The largest specific components of 
the 2009 impairment and abandonment related to the Floyd Shale acreage located in Mississippi and acreage in 
Oklahoma.  Additionally, we incurred write-offs related to acreage we believe we will not keep based on our 
current capital allocation plans or related to acreage that we do not believe will be prospective.  We generally 
expect impairments of unproved properties to be more likely to occur in periods of low commodity prices since 
fewer dollars will be available for exploratory and development efforts. 

Impairment of Goodwill.  We recorded a $9.5 million impairment of goodwill in 2008.  The goodwill was 

the result of our purchase of Agate Petroleum, Inc. in January 2005.  The impairment was a result of downward 
price adjustments to reserves for properties located in our Mid-Continent and Rocky Mountain regions and 
represented our entire goodwill balance.  We had no goodwill impairment in 2009. 

Impairment of materials inventory.  We recorded a $14.2 million impairment of materials inventory for 

the year ended December 31, 2009.  There were no impairments recorded in 2008.  The inventory impairment was 
caused by a decrease in the value of tubular goods and other raw materials. Impairments of materials inventory 
are impacted by fluctuations in the materials cost environment and increases and decreases in development and 
exploration activity, which generally trend with commodity prices. 

General and administrative.  General and administrative expense decreased $3.5 million or four percent 

to $76.0 million for the year ended December 31, 2009, compared with $79.5 million for the same period in 2008.  
G&A increased $0.01 to $0.70 per MCFE for the year ended December 31, 2009, compared to $0.69 per MCFE 
for the same period in 2008. 

General and administrative expense decreased due to an $11.3 million decrease in cash payments made 
under the Net Profits Plan.  As a result of the lower price realization we received in 2009 compared to 2008, the 
payouts from this plan were meaningfully smaller than those paid out in the prior year.  We expect payments 
made under the Net Profits Plan to trend with commodity prices. 

Compensation related costs allocated to general and administrative expense increased in 2009.  The 

largest increases were for headcount related costs, such as salary, benefits, and payroll taxes, which increased 
$10.6 million for the year ended December 31, 2009, when compared with the same period in 2008.  A significant 
driver of this headcount increase had been the conversion from contract lease operators to internal lease operators 
which began to take place in 2008.  Stock compensation was also up $ 3.3 million year over year as a result of 
layering in the second year of stock compensation amortization from our PSA long-term incentive program.  

64 

 
COPAS overhead reimbursements were $6.4 million higher for the year ended December 31, 2009, compared 
with the same period in 2008. 

Bad debt expense (recovery).  We recorded a recovery of bad debt expense of $5.2 million in 2009.  We 

recorded $16.7 million of bad debt expense in 2008 of which $16.6 million was a result of SemGroup L.P. and 
certain of its North American subsidiaries filing for bankruptcy protection.  Certain SemGroup entities had 
purchased a portion of our crude oil production.  This amount related to oil produced in June and July of 2008 that 
was fully reserved in the year ended December 31, 2008. 

Change in Net Profits Plan liability.  For the year ended December 31, 2009, this non-cash item was a 
$7.1 million benefit compared to $34.0 million benefit for the same period in 2008.  Significant decreases in oil 
and gas commodity prices have decreased the estimated liability for the future amounts to be paid to plan 
participants.  This liability is a significant management estimate.  Adjustments to the liability are subject to 
estimation and may change dramatically from period to period based on assumptions used for production rates, 
reserve quantities, commodity pricing, discount rates, tax rates, and production costs.  We expect the change in 
this liability to trend with commodity prices. 

Unrealized derivative (gain) loss.  We recognized a loss of $20.5 million for the year ended 
December 31, 2009, compared to a gain of $11.2 million for the same period in 2008.  This non-cash item is 
driven by the change in the value of our hedge position, as well as the portion of that position that is considered 
ineffective for accounting purposes.  Please refer to our discussion under the heading Oil and Gas Prices. 

Other expense.  Other expense increased $3.1 million to $13.5 million for the year ended 

December 31, 2009, compared with $10.4 million for the same period in 2008.  During the year ended December 
31, 2009, we incurred $1.5 million of expense related to the assignment of a drilling rig contract in our Rocky 
Mountain region.  We also incurred a loss related to hurricanes of $8.3 million for the year ended December 31, 
2009, compared with a loss related to hurricanes of $7.0 million for the same period in 2008. 

Income tax benefit (expense).  Income tax benefit totaled $60.1 million for 2009 compared to tax expense 

of $57.4 million for 2008, resulting in effective tax rates of 37.7 percent and 39.7 percent, respectively.  The 
effects of individual components of our tax rate can vary between periods resulting in fluctuations.  The effective 
rate change from 2008 primarily reflects the impact of goodwill impairment in that year, but changes in the mix of 
the highest marginal state tax rates and differing effects of other permanent differences, including the impact 
between years of the domestic production activities deduction and percentage depletion, also had an effect.  Our 
current income tax benefit in 2009 is $20.4 million compared to current income tax expense of $19.2 million in 
2008.  These amounts are 34 percent and 33 percent, respectively, of the total income tax benefit or expense for 
each period. Our 2009 current income tax benefit reflects creation of a net operating loss which we can carry back 
to one or more prior tax years to obtain a refund.  In future years, creation of net operating losses may not create 
current tax benefits.  During 2009 we observed with interest U.S. Congressional legislative activity relating to 
possible changes in taxation of our industry.  If the proposed legislation, which would reduce or eliminate current 
tax deductions for intangible drilling costs, the domestic production activities deduction, and percentage depletion 
allowance passes, we would expect our effective tax rate and the cash tax portion of our income tax expense to 
increase in the year the legislation becomes effective.

Comparison of Financial Results and Trends between 2008 and 2007 

Oil and gas production revenue.  Production increased seven percent to 114.6 BCFE for the year ended 

December 31, 2008, compared with 107.5 BCFE for the year ended December 31, 2007.  Production for the year 
ended December 31, 2007, includes approximately 6.8 BCFE related to non-core properties divested throughout 
2008.  The following table presents the regional changes in our production and oil and gas revenues and costs 
between the two years:

We grew daily production by approximately 18.6 MMCFE during 2008 compared to 2007.  The largest 

regional increase occurred in the ArkLaTex region as a result of the success in the Cotton Valley and James Lime 
programs.  Production in the South Texas & Gulf Coast region increased as a result of two acquisitions of 
properties targeting the shallow Olmos gas formation that were made in the second half of 2007 as well as several 
successful offshore wells.  The production growth in the Permian region was the result of continued development 
of the Wolfberry assets at Sweetie Peck and Halff East.  The declines in production in the Mid-Continent and 
Rocky Mountain regions were the result of the divestiture of non-core properties in these regions, which resulted 
in a smaller production base for 2008. 

Realized oil and gas hedge gain (loss).  We recorded a realized hedge loss of $101.1 million for the year 
ended December 31, 2008, mainly related to settlements on oil hedges.  For the year ended December 31, 2007, 
we recorded a realized hedge gain of $24.5 million mainly due to favorable settlements on natural gas hedges. 

Marketed gas system revenue and expense.  Marketed gas system revenue increased $32.2 million to 

$77.4 million for the year ended December 31, 2008, compared with $45.1 million for the comparable period of 
2007.  Concurrent with the increase in marketed gas system revenue, marketed gas system expense increased 
$29.7 million to $72.2 million for the year ended December 31, 2008, compared with $42.5 million for the 
comparable period of 2007.  The net margin has stayed consistent with historical performance. 

Other revenue.  Other revenues decreased $6.6 million to $2.1 million for the year ended 

December 31, 2008, compared with $8.7 million for 2007.  The decrease was due primarily to a $5.2 million gain 
recognized in 2007 associated with a global insurance settlement attributed to Hurricane Rita. 

Gain (loss) on divestiture activity.  We recorded a gain on sale of proved properties of $63.6 million for 

the year ended December 31, 2008, mainly related to the Abraxas divestiture in January 2008.

Oil and gas production expense.  Total production costs increased $53.1 million or 24 percent to 
$271.4 million for 2008, from $218.2 million in 2007.  Total oil and gas production costs per MCFE increased 
$0.33 to $2.36 for 2008, compared with $2.03 for 2007.  This increase was comprised of the following: 

  A $0.05 increase in overall transportation cost on a per MCFE basis was driven by the addition of 

Olmos shallow gas assets in the Maverick Basin that were acquired in the fourth quarter of 2007, as 
well as wells completed in 2008 that had higher transportation costs 

  A $0.13 increase in production taxes on a per MCFE basis due to the increase in realized prices 

between periods, particularly in the oil-weighted Rocky Mountain and Permian regions 

  A $0.10 increase in recurring lease operating expense on a per MCFE basis was related to higher 

costs, particularly in oil-weighted regions, for items such as fuel and fluid disposal and an increase in 
the South Texas & Gulf Coast region due to wells acquired and developed in South Texas during the 
fourth quarter of 2007 

  A $0.05 overall increase in workover lease operating expense on a per MCFE basis relating to 

workover charges in the Mid-Continent and South Texas & Gulf Coast regions. 

Depletion, depreciation, amortization and asset retirement obligation liability accretion.  DD&A 
increased $86.7 million, or 38 percent, to $314.3 million in 2008 compared with $227.6 million in 2007.  DD&A 
expense per MCFE increased 29 percent to $2.74 in 2008 compared to $2.12 in 2007.  This increase was due to a 
higher per unit rate associated with our acquisition and drilling costs in 2008 and 2007 caused by overall upward 
cost pressure in the industry in recent years. Additionally, this increase reflected the costs of production facilities 
in the offshore Gulf Coast that had increased significantly in recent years and that started impacting our DD&A 
rate as those projects begin production.  The DD&A per MCFE rate was further affected by downward revisions 
of 244.2 BCFE of proved reserves due to pricing and performance between December 31, 2008, and 
December 31, 2007, causing a general increase in DD&A. 

Exploration.  Exploration expense increased $1.4 million or two percent to $60.1 million in 2008 
compared with $58.7 million for 2007.  The increase was due to a $2.8 million increase in drilling arrangements 
and a $9.0 million increase in exploration overhead.  These increases were offset by a $2.8 million decrease in 
geological and geophysical expense as well as a $7.6 million decrease related to exploratory dry hole expense due 
to fewer and less expensive dry holes. 

Impairment of proved properties.  We recorded a $302.2 million impairment of proved oil and gas 

properties in 2008 compared to no impairment in 2007.  This impairment was primarily due to downward price 
adjustments to reserves and declining performance for properties primarily located in the South Texas & Gulf 
Coast region, as well as for gas properties in the Rocky Mountain region. 

Abandonment and impairment of unproved properties.  During the year, we abandoned or impaired 

$39.0 million of unproved properties.  Approximately $13.4 million related to acreage to which we had assigned 
value in 2007 acquisitions targeting the Olmos shallow gas formation.  The remaining write-offs related to 
acreage that we believed we either would not be able to hold in the current period of limited capital availability or 
to acreage that we did not believe would be prospective. 

Impairment of Goodwill.  We recorded a $9.5 million impairment of goodwill in 2008.  The goodwill was 

the result of our purchase of Agate Petroleum, Inc. in January 2005.  The impairment was a result of downward 
price adjustments to reserves for properties located in our Mid-Continent and Rocky Mountain regions and 
represented our entire goodwill balance. 

General and administrative.  General and administrative expenses increased $19.4 million or 32 percent 
to $79.5 million for 2008, compared with $60.1 million for 2007.  G&A increased $0.13 to $0.69 per MCFE for 
2008 compared to $0.56 per MCFE for the same period in 2007 as G&A grew at a faster rate than the seven 
percent increase in production.  A significant increase in employee count resulted in an increase in base employee 
67 

 
compensation, including taxes and benefits, of approximately $23.9 million between 2008 and 2007.  A 
significant driver of this headcount increase had been the conversion from contract lease operators to internal 
lease operators. 

An increase in 2008 oil and gas commodity prices triggered additional Net Profits Plan payments.  
Additionally, an increased percentage of the distribution dollars under the Net Profits Plan associated with general 
and administrative expense contributed to a $4.4 million increase in the current period realized expense in 2008 
compared with the same period in 2007. 

Cash bonus and long-term incentive compensation expense increased by $8.4 million for the year ended 

December 31, 2008, compared with the same period in 2007.  The increase resulted from the application of the 
Cash Bonus Plan as amended on March 28, 2008 and an increase in our employee count. 

The amounts described above were offset by a $9.1 million increase in the amount of G&A that was 

allocated to exploration expense and an $8.2 million increase in COPAS overhead reimbursements.  Our COPAS 
overhead reimbursements from operations increased due to an increase in our operated well count from our 
drilling program. 

Change in Net Profits Plan liability.  For the year ended December 31, 2008, this non-cash item was a 

benefit of $34.0 million compared to an expense of $50.8 million for the same period in 2007.  Significant 
decreases in oil and gas commodity prices during the last half of 2008 and payments out of the plan have 
decreased the estimated liability for the future amounts to be paid to plan participants. 

Bad debt expense.  We recorded $16.7 million of bad debt expense in 2008, of which $16.6 million was a 
result of SemGroup, L.P. and certain of its North American subsidiaries filing for bankruptcy protection.  Certain 
SemGroup entities had purchased a portion of our crude oil production.  This amount related to oil produced in 
June and July of 2008 that was fully reserved in the year ended December 31, 2008. 

Income tax benefit (expense). Income tax expense totaled $57.4 million for 2008 and $109.0 million for 

2007, resulting in effective tax rates of 39.7 percent and 36.8 percent, respectively.  The effective rate change 
from 2007 was primarily due to the impact of goodwill impairment, changes in the mix of the highest marginal 
state tax rates, and also reflects other permanent differences including differing estimated effects between years of 
the domestic production activities deduction. 

Our current income tax expense in 2008 was $19.2 million compared to $17.6 million in 2007.  These 

amounts were 33 percent and 16 percent of the total income tax expense for the respective periods. 

Overview of Liquidity and Capital Resources 

In order to meet our projected growth targets, we will have to effectively invest capital into new projects 

and acquisitions.  The following analysis and discussion includes our assessment of market risk and possible 
effects of inflation and changing prices. 

Sources of cash 

Based on our current outlook, we expect our generated cash flow from operations in 2010 plus proceeds 
from our pending Rocky Mountain oil and other non-core asset divestiture packages to fund our exploration and 
development budget for 2010.  Accordingly, we do not expect to access the capital markets in 2010.  Throughout 
2009, we identified and marketed non-core oil and gas properties.  Net cash proceeds from transactions that 
closed in 2009, after commission costs, were $39.9 million.    Subsequent to year end, we closed the Wyoming 
portion of our Rocky Mountain oil package and we plan to close the remaining North Dakota portion by the end 
of the first quarter of 2010.  We anticipate we will continue to evaluate our property base to identify and divest of 
properties we consider non-core to our strategic goals. 

68 

 
Our primary sources of liquidity are the cash flows provided by operating activities, use of our credit 

facility, sales of non-core properties, and access to capital markets.  All of these sources can be impacted by the 
general condition of the broad economy and by significant fluctuations in oil and gas prices, operating costs, and 
volumes produced all of which affect us and our industry.  We have no control over the market prices for oil and 
natural gas, although we are able to influence the amount of our net realized revenues related to our oil and gas 
sales through the use of derivative contracts.  The borrowing base on our credit facility could be reduced as a 
result of lower commodity prices or sales of non-core producing properties.  Historically, decreases in market 
prices have limited our industry’s access to the capital markets.  We believe the public debt markets are currently 
accessible.  Equity and convertible debt issuances are also available to us as alternative financing sources.  We do 
not anticipate the need to raise public debt or equity financing in the near term, however these are options we 
would consider under the appropriate circumstances.  We intend to rely on our credit facility for borrowings. 

Current credit facility 

On April 14, 2009, we entered into an amended $1.0 billion senior secured revolving credit facility with 

twelve participating banks.  The initial borrowing base was set at $900 million.  On September 29, 2009, the 
lending group redetermined our reserve-backed borrowing base under the credit facility at $900 million.  We have 
been provided a $678 million commitment amount by the bank group.  The new amended credit facility 
agreement has a maturity date of July 31, 2012.  Management believes that the current commitment is sufficient 
for our liquidity needs.  To date, we have experienced no issues drawing upon our credit facility.  No individual 
bank participating in the credit facility represents more than 16 percent of the lending commitments under the 
credit facility.  We monitor the credit environment closely and have frequent discussions with the lending group. 

As of February 16, 2010, we had $467.0 million of available borrowing capacity under this facility.  

Interest and commitment fees are accrued based on the borrowing base utilization percentage.  Euro-dollar loans 
accrue interest at LIBOR plus the applicable margin from the utilization table located in Note 5 of Part IV, Item 
15 of this report, and Alternate Base Rate loans accrue interest at Prime plus the applicable margin from the 
utilization table.  Outstanding loans reduce the amount available under the commitment amount on a dollar-for-
dollar basis, as do letters of credit.  Borrowings under the facility are secured by mortgages on the majority of our 
oil and gas properties and a pledge of the common stock of our material subsidiary companies. 

Our weighted-average interest rate paid in 2009 was 5.4 percent and included fees paid on the unused 

portion of the credit facility’s aggregate commitment amount and amortization of deferred financing costs and the 
debt discount.  We decreased our net borrowings from the previous year by $112.0 million when comparing the 
ending 2009 and 2008 balance sheet amounts.  A decrease in the average outstanding credit facility balance 
throughout 2009, plus a decrease in interest rates, was offset by higher applicable margins, higher commitment 
fees on the unused portion of our credit facility and amortization of upfront financing costs and the 3.50% Senior 
Convertible Notes debt discount.  This resulted in interest expense of $28.9 million in 2009 compared with $27.0 
million in 2008. 

We are subject to customary covenants under our credit facility, including limitations on dividend 

payments and requirements to maintain certain financial ratios, which include debt to earnings before interest, 
taxes, depreciation, and amortization of less than 3.5 to 1.0 and a current ratio as defined by our credit agreement 
of not less than 1.0.  As of December 31, 2009, our debt to EBITDA ratio and current ratio as defined by our 
credit agreement, were 1.10 and 2.75, respectively.  We are in compliance with all covenants under this credit 
facility and expect to be in compliance for at least 12 months. 

We may from time to time repurchase certain amounts of our outstanding debt securities for cash and/or 

through exchanges for other securities.  Such repurchases or exchanges may be made in open market transactions, 
privately negotiated transactions, or otherwise.  Any such repurchases or exchanges will depend on prevailing 
market conditions, our liquidity requirements, contractual restrictions, compliance with securities laws and other 
factors.  The amounts involved in any such transaction may be material. 

Uses of cash 

69 

 
We use cash for the acquisition, exploration, and development of oil and gas properties, and for the 
payment of debt obligations, trade payables, income taxes, common stock repurchases, and stockholder dividends.  
During 2009 we spent $379.3 million of cash on capital development and $76,000 of cash for property 
acquisitions.  These amounts differ from the cost incurred amounts based on the timing of cash payments 
associated with these activities as compared to the accrual-based activity upon which the costs incurred amounts 
are presented.  These cash flows were funded using cash inflows from operations, proceeds from the sale of 
assets, and available borrowing capacity under our revolving credit facility. 

Expenditures for exploration and development of oil and gas properties and acquisitions are the primary 
use of our capital resources.  Our capital and exploration expenditures in 2010 will be funded with current year 
operating cash flows and proceeds from the divestiture of non-core assets.  The amount and allocation of future 
capital expenditures will depend upon a number of factors including the number and size of available economic 
acquisitions and drilling opportunities, our cash flows from operating, investing and financing activities, and our 
ability to assimilate acquisitions.  Also the impact of oil and gas prices on investment opportunities, the 
availability of capital and borrowing facilities, and the success of our development and exploratory activities 
could lead to changes in funding requirements for future development.  We regularly review our capital 
expenditure budget to assess changes in current and projected cash flows, acquisition opportunities, debt 
requirements, and other factors. 

As of the filing date of this report we have Board authorization to repurchase up to 3,072,184 shares of 
our common stock under our stock repurchase program.  Shares may be repurchased from time to time in open 
market transactions or privately negotiated transactions subject to market conditions and other factors including 
certain provisions of our existing bank credit facility agreement, compliance with securities laws, and the terms 
and provisions of our stock repurchase program.  There were no share repurchases in 2009. 

Current proposals to fund the federal budget include eliminating or reducing current tax deductions for 

intangible drilling costs, the domestic production activities deduction, and percentage depletion.  Legislation 
modifying or eliminating these deductions would have the immediate effect of reducing operating cash flows 
thereby reducing funding available for our exploration and development capital programs and those of our peers 
in the industry.  These funding reductions could have a significant adverse effect on drilling in the United States 
for a number of years. 

In 2009 we paid $6.2 million in dividends to our stockholders.  Our intention is to continue to make these 
dividend payments for the foreseeable future subject to our future earnings, our financial condition, possible credit 
facility covenants, and other currently unexpected factors which could arise. 

The following table presents amounts and percentage changes between years in net cash flows from our 

operating, investing, and financing activities.  The analysis following the table should be read in conjunction with 
our consolidated statements of cash flows in Part IV, Item 15 of this report.

Analysis of cash flow changes between 2009 and 2008 

Operating activities.  Cash received from oil and gas production revenues, net of the realized effects of 
hedging, decreased $438.5 million to $751.8 million for the year ended December 31, 2009.  The decrease was 
the result of a five percent decrease in production and a 31 percent decrease in our net realized price after 
hedging, resulting in a 35 percent decrease in production revenue.  Included in the 2009 oil and gas production 
revenue amounts is $140.6 million of net realized hedging gains.  We received $9.9 million in income tax refunds 
in 2009 compared to payments of $17.3 million during 2008. 

Investing activities.  Cash used for investing activities decreased $369.7 million for the year ended 

December 31, 2009, compared with the same period in 2008.  Cash outflows for 2009 capital expenditures for 
development and exploration activities decreased $367.3 million or 49 percent to $379.3 million, which reflects a 
reduced level of activity as a result of lower commodity prices.  Total cash outflow for 2009 related to the 
acquisition of oil and gas properties decreased $81.7 million or 100 percent to $76,000.  We had no significant 
acquisitions of oil and gas properties in 2009, compared with the acquisition of Carthage Field properties during 
2008.  Proceeds from an insurance settlement relating to Hurricane Ike were $16.8 million for the year ended 
December 31, 2009, compared with the same period in 2008 when we received no proceeds from insurance 
settlements.  Proceeds from the sale of oil and gas properties for the year ended December 31, 2009, decreased 
$139.0 million compared to the same period in 2008.  Current year proceeds received from the sale of oil and gas 
properties relate to non-core properties located in the Rocky Mountain region that were divested of in the fourth 
quarter of 2009.  The majority of the 2008 proceeds related to non-core properties sold to Abraxas in the first 
quarter of 2008. 

Financing activities.  Net repayments to our credit facility increased $127.0 million for the year ended 
December 31, 2009, compared to 2008.  We spent $11.1 million on debt issuance costs for our amended credit 
facility during the year ended December 31, 2009.  We did not incur any debt issuance costs during 2008.  Our 
income tax benefit attributable to the exercise of stock awards decreased $13.9 million in the year ended 
December 31, 2009, compared with 2008.  We received $8.8 million less in proceeds from the sale of common 
stock in 2009, than in 2008.  Additionally, we invested $77.2 million less to repurchase shares of our common 
stock during 2009, than in 2008. 

We had $10.6 million in cash and cash equivalents and a working capital deficit of $87.6 million as of 

December 31, 2009, compared to $6.1 million in cash and cash equivalents and working capital of $15.2 million 
as of December 31, 2008. 

Analysis of cash flow changes between 2008 and 2007 

Operating activities.  Cash received from oil and gas production revenues, net of the realized effects of 
hedging, increased $265.2 million to $1.2 billion for the year ended December 31, 2008.  The increase was the 
result of a seven percent increase in production and a 16 percent increase in our net realized price after hedging, 
resulting in a 24 percent increase in production revenue.  Included in the oil and gas production revenue amounts 
was $101.1 million of net realized hedging losses.  Net cash payments made for income taxes increased 
$18.5 million due to fluctuating oil and gas prices which increased our estimated quarterly income tax payments 
in 2008. 

Investing activities.  Total cash outflow for 2008 capital expenditures for leasehold and drilling activities 

increased $107.6 million or 17 percent to $746.6 million.  Total cash outflow for 2008 related to the acquisition of 
oil and gas properties decreased $101.1 million or 55 percent to $81.8 million.  Cash received from the sale of oil 
and gas properties increased $178.4 million and deposits to restricted cash increased $14.4 million for 2008 as 
compared to 2007. 

Financing activities.  Net repayments to our credit facility decreased $64.0 million for the year ended 
December 31, 2008, compared to 2007.  We received $280.7 million less during 2008, compared to the same 
period in 2007, from the issuance of senior convertible debt.  Our income tax benefit attributable to the exercise of 
stock awards increased $3.9 million to $13.9 million for the year ended December 31, 2008, compared with the 

71 

 
same period in 2007.  We received $1.9 million more proceeds from the sale of common stock in 2008, compared 
to 2007.  Additionally, we invested $51.3 million more to repurchase shares of our common stock during 2008 
compared to 2007. 

We had $6.1 million in cash and cash equivalents and working capital of $15.2 million as of 
December 31, 2008, compared to $43.5 million in cash and cash equivalents and a working capital deficit of 
$92.6 million as of December 31, 2007.

Commodity Price Risk and Interest Rate Risk 

We are exposed to market risk, including the effects of changes in oil and gas commodity prices and 
changes in interest rates.  Changes in interest rates can affect the amount of interest we earn on our cash, cash 
equivalents, and short-term investments and the amount of interest we pay on borrowings under our revolving 
credit facility.  Changes in interest rates do not affect the amount of interest we pay on our fixed-rate 3.50% 
Senior Convertible Notes, but do affect their fair market value. 

Market risk is estimated as the potential change in fair value resulting from an immediate hypothetical 
one percentage point parallel shift in the yield curve.  For fixed-rate debt, interest changes affect the fair market 
value but do not impact results of operations or cash flows.  Conversely, interest rate changes for floating-rate 
debt generally do not affect the fair market value but do impact future results of operations and cash flows, 
assuming other factors are held constant.  The carrying amount of our floating-rate debt typically approximates its 
fair value.  We had $188.0 million of floating-rate debt outstanding as of December 31, 2009.  Our fixed-rate debt 
outstanding, net of debt discount, at this same date was $266.9 million.  As of December 31, 2009, we do not have 
any interest rate hedges in place to mitigate potential risks. 

Since we produce and sell natural gas and crude oil, our financial results are affected when prices for 

these commodities fluctuate.  The following table reflects our estimate of the effect on net cash flows from 
operations of a ten percent change in our average realized sales price for natural gas, for oil, and in combination 
for the years presented, inclusive of the impact of hedging.  These amounts have been reduced by the effective 
income tax rate applicable to each period since a reduction in revenue would reduce cash requirements to pay 
income taxes.  General and administrative expenses have not been adjusted.  To fund the capital expenditures we

incurred in those years we would have been required to utilize amounts under our credit facility as a source of 
funds.  In each of these years we would have had sufficient borrowing base available under our credit facility to 
meet this contingency without reducing or eliminating expenditures or altering our growth strategy.

We enter into hedging transactions in order to reduce the impact of fluctuations in commodity prices. 

Please refer to Note 10 – Derivative Financial Instruments of Part IV, Item 15 of this report for additional 
information about our oil and gas derivative contracts, and additional information is below under the caption 
Summary of Oil and Gas Production Hedges in Place.  We do not anticipate significant changes in existing hedge 
contracts or derivative contract transactions. 

Summary of Oil and Gas Production Hedges in Place 

Our oil and natural gas derivative contracts include swap and costless collar arrangements.  All contracts 

are entered into for other-than-trading purposes.  Please refer to Note 10 – Derivative Financial Instruments in 
Part IV, Item 15 of this report for additional information regarding accounting for our derivative transactions. 

Our net realized oil and gas prices are impacted by hedges we have placed on future forecasted 
production.  Hedging is an important part of our financial risk management program.  The amount of production 
we hedge is driven by the amount of debt on our consolidated balance sheet and the level of capital and long-term 
commitments we have made.  In the case of a significant acquisition of producing properties, we will consider 
hedging a portion of the anticipated production in order to protect the economics assumed at the time of the 
acquisition.  As of December 31, 2009, and through the date of this filing, our hedged positions of anticipated 
production through 2012 totaled approximately 6 million Bbls of oil, 63 million MMBtu of natural gas, and 1 
million Bbls of natural gas liquids. 

In a typical commodity swap agreement, if the agreed-upon published third-party index price is lower 

than the swap fixed price, we receive the difference between the index price per unit of production and the agreed 
upon swap fixed price.  If the index price is higher than the swap fixed price, we pay the difference.  For collar 
agreements, we receive the difference between an agreed upon index and the floor price if the index price is below 
the floor price.  We pay the difference between the agreed upon contracted ceiling price and the index price if the 
index price is above the contracted ceiling price.  No amounts are paid or received if the index price is between 
the contracted floor and ceiling prices.

The following table describes the volumes, average contract prices, and fair value of contracts we have in 

place as of December 31, 2009.  We seek to minimize basis risk and index the majority of our oil contracts to 
NYMEX WTI prices and the majority of our gas contracts to various regional index prices associated with 
pipelines in proximity to our areas of gas production.

This table includes the remaining unfunded portion of our estimated pension liability of $9.5 million even 
though we recognize that we cannot determine with accuracy the timing of future payments.  The Company is not 
required to make a contribution to the Pension Plan in 2010.  We made contributions of $2.0 million, $2.5 million, 
and $2.2 million in 2009, 2008, and 2007, respectively, towards the pension liability.  The table also includes 
$166.1 million in other long-term liabilities that represents six years of undiscounted forecasted payments for the 
Net Profits Plan.  Payments are expected to gradually decrease for the years beyond what is shown in this table.  
The amounts recorded on the consolidated balance sheets reflect all future Net Profits Plan payments and the 
impact of discounting and therefore differ from the amounts disclosed in this table.  The variability in the amount 
of payments will be a direct reflection of commodity prices, production rates, capital expenditures, and operating 
costs in future periods.  Predicting the timing and amounts of payments associated with this liability is contingent 
upon estimates of appropriate discount factors, adjusting for risk and time value, and upon a number of factors 
that we cannot control.  The components of the operating leases are discussed in more detail in Note 6 – 
Commitments and Contingencies of Part IV, Item 15 of this report. 

The scheduled repayment of the long-term credit facility is 2012.  Accordingly, it has been disclosed in 

the table as such.  Since this is a revolving credit facility, the actual payments will vary significantly.  We 
anticipate refinancing this obligation prior to its expiration date.  For purposes of this table, we assume we will net 
share settle the 3.50% Senior Convertible Notes.  Accordingly, $22.7 million of interest payments related to the 
3.50% Senior Convertible Notes are included in the long-term debt line in table above.  We have excluded asset 
retirement obligations because we are not able to accurately predict the precise timing of these amounts.  Pension

liabilities, asset retirement obligations, and Net Profits Plan are discussed in Note 8 – Pension Benefits, Note 9 – 
Asset Retirement Obligations, and Note 7 – Compensation Plans of Part IV, Item 15 of this report. 

This table also includes estimated oil and natural gas derivative payments of $119.4 million based on 

future market prices as of December 31, 2009.  This amount represents only the cash outflows; it does not include 
estimated oil and gas derivative receipts of $38.0 million that would be paid based on December 31, 2009, market 
prices.  The net liability of $81.4 million represents cash flows from the intrinsic value of our collar arrangements 
and differs in amount from our recorded fair value, which as of December 31, 2009, was a net liability of $80.9 
million.  The fair value considers time value, volatility, and the risk of non-performance for us and for our 
counterparties.  Both the intrinsic value and fair value will change as oil and natural gas commodity prices 
change.  Please refer to the discussion above under the caption Summary of Oil and Gas Production Hedges in 
Place and Note 10 – Derivative Financial Instruments in Part IV, Item 15 of this report for additional information 
regarding our oil and gas hedges. 

We believe that we will continue to pay annual dividends of $0.10 per share.  We anticipate making cash 

payments for income taxes, dependent on net income and capital spending. 

Off-balance Sheet Arrangements 

As part of our ongoing business, we have not participated in transactions that generate relationships with 
unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special 
purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements 
or other contractually narrow or limited purposes.  As of December 31, 2009, we have not been involved in any 
unconsolidated SPE transactions. 

We evaluate our transactions to determine if any variable interest entities exist.  If it is determined that we 

are the primary beneficiary of a variable interest entity, that entity is consolidated into our consolidated financial 
statements. 

Critical Accounting Policies and Estimates 

Our discussion of financial condition and results of operations is based upon the information reported in 
our consolidated financial statements.  The preparation of these consolidated financial statements requires us to 
make assumptions and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses as 
well as the disclosure of contingent assets and liabilities as of the date of our financial statements.  We base our 
decisions affecting the estimates we use on historical experience and various other sources that are believed to be 
reasonable under the circumstances.  Actual results may differ from the estimates we calculate due to changes in 
business conditions or due to unexpected circumstances.  Policies we believe are critical to understanding our 
business operations and results of operations are detailed below.  For additional information on our significant 
accounting policies, please refer to Note 1 – Summary of Significant Accounting Policies, Note 9 – Asset 
Retirement Obligations, and Note 16 – Disclosures about Oil and Gas Producing Activities in Part IV, Item 15 of 
this report. 

Proved Oil and gas reserve quantities.  Estimated reserve quantities and the related estimates of future net 

cash flows are critical estimates for our company because they affect the perceived value of an exploration and 
production company.  Additionally, they are used in comparative financial analysis ratios and are used as the basis 
for the most significant accounting estimates in our financial statements.  Those significant accounting estimates 
include the periodic calculations of depletion, depreciation, and impairment of our proved oil and gas properties 
and the estimates of our liability for future payments under the Net Profits Plan.  Future cash inflows and future 
production and development costs are determined by applying prices and costs, including transportation, quality 
differentials, and basis differentials, applicable to each period to the estimated quantities of proved oil and gas 
reserves remaining to be produced as of the end of that period.  Expected cash flows are discounted to present 
value using a discount rate that depends upon the purpose for which the reserve estimates will be used.  For 
example, the standardized measure calculations required by Accounting Standards Codification Topic 932 
Extractive Activities – Oil and Gas requires a ten percent discount rate to be applied.  Although reserve estimates 

79 

 
are inherently imprecise, and estimates of new discoveries and undeveloped locations are more imprecise than 
those of established producing oil and gas properties, we make a considerable effort in estimating our reserves, 
including using independent reserve engineering consultants.  We expect that periodic reserve estimates will 
change in the future as additional information becomes available and as oil and gas prices and operating and 
capital costs change.  We evaluate and estimate our proved oil and gas reserves at December 31 and June 30 of 
each year.  For purposes of depletion, depreciation, and impairment, reserve quantities are adjusted at all interim 
periods for the estimated impact of additions and dispositions.  Changes in depletion, depreciation, or impairment 
calculations caused by changes in reserve quantities or net cash flows are recorded in the period the reserve 
estimates change. 

The following table presents information regarding reserve changes from period to period that reflect 

changes from items we do not control, such as price, and from changes resulting from better information due to 
production history, and from well performance.  These changes do not require a capital expenditure on our part, 
but may have resulted from capital expenditures we incurred to develop other estimated proved reserves.

We have added 282.8 BCFE of reserves over a three-year period, excluding divestitures.  A 99.7 BCFE 

decrease in reserves was a result of changes in engineering estimates based on the performance of our oil and gas 
properties.  A 153.2 BCFE decrease in reserves was a result of price changes.  As previously noted, oil and gas 
prices are volatile, and estimates of reserves are inherently imprecise.  Consequently, we anticipate we may 
continue to experience these types of changes.

Successful efforts method of accounting.  Generally accepted accounting principles provide for two 

alternative methods for the oil and gas industry to use in accounting for oil and gas producing activities.  These 
two methods are generally known in our industry as the full cost method and the successful efforts method.  Both 
methods are widely used.  The methods are different enough that in many circumstances the same set of facts will 
provide materially different financial statement results within a given year.  We have chosen the successful efforts 
method of accounting for our oil and gas producing activities, and a detailed description is included in Note 1 of 
Part IV, Item 15 of this report. 

Revenue recognition.  Our revenue recognition policy is significant because revenue is a key component 
of our results of operations and our forward-looking statements contained in our analysis of liquidity and capital 
80 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
resources.  We derive our revenue primarily from the sale of produced natural gas, natural gas liquids, and crude 
oil.  We report revenue as the gross amounts we receive before taking into account production taxes and 
transportation costs, which are reported as separate expenses.  Revenue is recorded in the month our production is 
delivered to the purchaser, but payment is generally received between 30 and 90 days after the date of production.  
No revenue is recognized unless it is determined that title to the product has transferred to a purchaser.  At the end 
of each month we make estimates of the amount of production delivered to the purchaser and the price we will 
receive.  We use our knowledge of our properties, their historical performance, NYMEX and local spot market 
prices, and other factors as the basis for these estimates.  Variances between our estimates and the actual amounts 
received are recorded in the month payment is received.  A ten percent change in our year-end revenue accrual 
would have impacted net income before tax by approximately $8 million in 2009. 

Crude oil and natural gas hedging.  Our crude oil and natural gas hedging contracts are intended to and 
usually do qualify for cash flow deferral hedge accounting under Accounting Standards Codification Topic 815.  
Under this guidance a majority of the gain or loss from a contract qualifying as a cash flow hedge is deferred from 
recognition in the consolidated statement of operations.  The realized gain or loss reflected in the consolidated 
statement of operations is based on actual hedge contract settlements.  If our natural gas and crude oil hedge 
contracts did not qualify for hedge accounting treatment or if we chose not to use hedge accounting methodology, 
our periodic consolidated statements of operations could include significant changes in the estimate of non-cash 
derivative gain or loss due to swings in the value of these contracts.  Consequently, we would report a different 
amount of oil and gas hedge loss in our statements of operations.  These fluctuations could be especially 
significant in a volatile pricing environment such as what we have encountered over the last few years.  The 
amounts recorded to accumulated other comprehensive income (loss) of $103.3 million of loss, $223.5 million of 
income, and $170.0 million of loss for 2009, 2008, and 2007, respectively, would have increased or decreased net 
income after tax if our hedges did not qualify as cash flow deferral hedges under Accounting Standards 
Codification Topic 815. 

Change in Net Profits Plan Liability.  We record the estimated liability of future payments for our Net 

Profits Plan.  The estimated liability is calculated based on a number of assumptions, including estimates of 
proved oil and gas reserves, recurring and workover lease operating expense, production and ad valorem tax rates, 
present value discount factors, and pricing assumptions.  Additional discussion is included in the analysis in the 
above section titled Overview of the Company, under the heading Net Profits Plan.  In December 2007 our Board 
approved an incentive compensation plan restructuring whereby the Net Profits Plan was replaced with a long-
term incentive program utilizing performance shares.  As a result, the 2007 Net Profits Plan pool was the last pool 
established. 

Asset retirement obligations.  We are required to recognize an estimated liability for future costs 

associated with the abandonment of our oil and gas properties.  We base our estimate of the liability on our 
historical experience in abandoning oil and gas wells projected into the future based on our current understanding 
of federal and state regulatory requirements.  Our present value calculations require us to estimate the economic 
lives of our properties, assume what future inflation rates apply to external estimates, and determine what credit 
adjusted risk-free rate discount to use.  The impact to the consolidated statement of operations from these 
estimates is reflected in our depreciation, depletion, and amortization calculations and occurs over the remaining 
life of our oil and gas properties. 

Valuation of long-lived and intangible assets.  Our property and equipment are recorded at cost.  An 

impairment allowance is provided on unproven property when we determine that the property will not be 
developed or the carrying value will not be realized.  We evaluate the realizability of our proved properties and 
other long-lived assets whenever events or changes in circumstances indicate that impairment may be appropriate.  
Our impairment test compares the expected undiscounted future net revenues from property, using escalated 
pricing, with the related net capitalized cost of the property at the end of each period.  When the net capitalized 
costs exceed the undiscounted future net revenue of a property, the cost of the property is written down to its 
estimate of fair value, which is determined by applying a discount rate we believe is indicative of the current 
market.  Our criteria for an acceptable internal rate of return are subject to change over time.  Different pricing 
assumptions or discount rates could result in a different calculated impairment.  We recorded a $174.8 million 
impairment of proved oil and gas properties in 2009.  A significant decrease in commodity prices and increase in 
81 

 
differentials during the first quarter of 2009 caused the majority of the non-cash impairment.  The largest portion 
of the impairment in 2009 was $97.3 million related to assets located in the Mid-Continent region that were 
significantly impacted by lower prices and wider than normal differentials. 

Income taxes.  We provide for deferred income taxes on the difference between the tax basis of an asset or 

liability and its carrying amount in our financial statements in accordance with Accounting Standards 
Codification Topic 740.  This difference will result in taxable income or deductions in future years when the 
reported amount of the asset or liability is recovered or settled, respectively.  Considerable judgment is required in 
determining when these events may occur and whether recovery of an asset is more likely than not.  Additionally, 
our federal and state income tax returns are generally not filed before the consolidated financial statements are 
prepared, therefore, we estimate the tax basis of our assets and liabilities at the end of each period as well as the 
effects of tax rate changes, tax credits, and net operating and capital loss carryforwards and carrybacks.  
Adjustments related to differences between the estimates we use and actual amounts we report are recorded in the 
periods in which we file our income tax returns.  These adjustments and changes in our estimates of asset 
recovery and liability settlement could have an impact on our results of operations.  A one percent change in our 
effective tax rate would have changed our calculated income tax benefit by $675,000 for the year ended 
December 31, 2009. 

Other Liquidity and Capital Resources Information 

Pension Benefits 

Substantially all of our employees who meet age and service requirements participate in a non-

contributory defined benefit pension plan.  At December 31, 2009, and 2008, our underfunded status was 
$9.4 million and $8.2 million, respectively.  The increase in underfunding from 2008 to 2009 was primarily 
attributable to lower discount rates, which were 6.6 percent in 2008 and 6.1 percent in 2009.  Our pension plan 
assets increased from $6.6 million at December 31, 2008, to $9.1 million at December 31, 2009.  On an Employee 
Retirement Income Security Act basis, the Company’s pension plan remains fully funded at January 1, 2010.  We 
are not required to make any contributions to the pension plan in 2010.  For additional information please refer to 
Note 8 – Pension Benefits in Part IV, Item 15 of this report. 

Accounting Matters 

Please refer to Note 5 – Long-term Debt, Note 8 – Pension Benefits, Note 10 - Derivative Financial 
Instruments, Note 11 – Fair Value Measurements, Note 16 – Disclosures about Oil and Gas Producing Activities, 
and the section entitled ―Recently Issued Accounting Standards‖ under Note 1 – Summary of Significant 
Accounting Policies for additional information on the recent adoption of new authoritative accounting guidance in 
Part IV, Item 15 of this report. 

Environmental 

St. Mary’s compliance with applicable environmental regulations has to date not resulted in significant 
capital expenditures or material adverse effects on our liquidity or results of operations.  We believe we are in 
substantial compliance with environmental regulations and do not currently anticipate that material future 
expenditures will be required under the existing regulatory framework.  However, we are unable to predict the 
impact that compliance with future laws or regulations, such as those currently being considered as discussed 
below, may have on future capital expenditures, liquidity, and results of operations. 

The U.S. Congress is currently considering legislation that would amend the Safe Drinking Water Act to 
eliminate an existing exemption from federal regulation of hydraulic fracturing activities.  Hydraulic fracturing is 
a common process in our industry of creating artificial cracks, or fractures, in deep underground rock formations 
through the pressurized injection of water, sand and other additives to enable oil or natural gas to move more 
easily through the rock pores to a production well.  This process is often necessary to produce commercial 
quantities of oil and natural gas from many reservoirs, especially shale rock formations.  We routinely utilize 
hydraulic fracturing in many of our reservoirs, and our Eagle Ford, Haynesville, Marcellus, and Woodford shale 

82 

 
programs utilize or contemplate the utilization of hydraulic fracturing.  Currently, regulation of hydraulic 
fracturing is primarily conducted at the state level through permitting and other compliance requirements.  If 
adopted, the proposed amendment to the Safe Drinking Water Act could result in additional regulations and 
permitting requirements at the federal level.  Those additional regulations and permitting requirements, as well as 
other regulatory developments at the state level, could lead to significant operational delays and increased 
operating costs, and could make it more difficult to perform hydraulic fracturing. 

Climate Change 

Climate change has become the subject of an important public policy debate.  While climate change 
remains a complex issue, scientific research suggests that an increase in greenhouse gas emissions may pose a risk 
to society and the environment.  The oil and natural gas exploration and production industry is a source of certain 
greenhouse gas emissions, namely carbon dioxide and methane, and future restrictions on the combustion of fossil 
fuels or the venting of natural gas could have a significant impact on our future operations.  We are actively 
monitoring the following climate change related issues: 

Impact of Legislation and Regulation.  The commercial risk associated with the exploration and 
production of fossil fuels lies in the uncertainty of government-imposed climate change legislation, including cap 
and trade systems, and regulations that may affect us, our suppliers, and our customers.  The cost of meeting these 
requirements may have an adverse impact on our financial condition, results of operations and cash flows, and 
could reduce the demand for the oil and natural gas that we produce.  The U.S. Congress and several states are 
considering adopting climate change legislation.  However, the current state of development of many state and 
federal climate change regulatory initiatives makes it difficult to predict with certainty the future impact on us, 
including accurately estimating the related compliance costs that we may incur. 

Impact of U.S. Participation in International Accords.  The U.S. has participated in international 
discussions to develop a treaty or other agreement to require reductions in greenhouse gas emissions after 2012, 
and has indicated that it wishes to associate itself with the Copenhagen Accord, which includes a non-binding 
commitment to reduce greenhouse gas emissions.  While no specific new international climate change accord has 
been adopted that would affect our current operating locations, the current state of development of many 
initiatives makes it difficult to assess the timing or effect of any pending discussions of future accords or predict 
with certainty the future costs that we may incur in order to comply with any applicable requirements from future 
international treaties or regulations. 

Indirect Consequences of Regulation or Business Trends.  We believe that there are both risks and 

opportunities arising from climate change issues.  See Items 1 and 2. Business and Properties – Government 
Regulations, and the following risk factors listed in Item 1A. Risk Factors – 

•  We are subject to operating and environmental risks and hazards that could result in substantial 

losses. 

•  Our operations are subject to complex laws and regulations, including environmental regulations 

that result in substantial costs and other risks. 

•  Possible legislation and regulations related to global warming and climate change could have an 

adverse effect on our operations and the demand for oil and natural gas. 

In terms of opportunities, the regulation of greenhouse gas emissions and the introduction of alternative 

incentives, such as enhanced oil recovery, carbon sequestration and low carbon fuel standards, could benefit us in 
a variety of ways.  For example, although climate change legislation could reduce the overall demand for the oil 
and natural gas that we produce, the relative demand for natural gas may increase since the burning of natural gas 
produces lower levels of emissions than other readily available fossil fuels such as oil and coal.  In addition, if 
renewable resources, such as wind or solar power become more prevalent, natural gas-fired electric plants may 
provide an alternative backup to maintain consistent electricity supply.  Also, if states adopt low-carbon fuel 
standards, natural gas may become a more attractive transportation fuel.  More than 60% of our 2009 production 

83 

 
on an MCFE basis was natural gas.  Market-based incentives for the capture and storage of carbon dioxide in 
underground reservoirs, particularly in oil and natural gas reservoirs, could also benefit us through the potential to 
obtain greenhouse gas emission allowances or offsets from or government incentives for the sequestration of 
carbon dioxide. 

Physical Impacts of Climate Change on our Costs and Operations.  There has been public discussion that 

climate change may be associated with extreme weather conditions such as more intense hurricanes, 
thunderstorms, tornados and snow or ice storms, as well as rising sea levels.  Extreme weather conditions can 
increase our costs, and damage resulting from extreme weather may not be fully insured.  However, the extent to 
which climate change may lead to increased storm or weather hazards affecting our operations is difficult to 
identify at this time.  See Item 1A. Risk Factors – We are subject to operating and environmental risks and 
hazards that could result in substantial losses.

CONTROLS AND PROCEDURES 

We maintain a system of disclosure controls and procedures that are designed to ensure that information 

required to be disclosed in our SEC reports is recorded, processed, summarized, and reported within the time 
periods specified in the SEC’s rules and forms, and to ensure that such information is accumulated and 
communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, as 
appropriate, to allow for timely decisions regarding required disclosure. 

We carried out an evaluation, under the supervision and with the participation of our management, 

including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and 
operation of our disclosure controls and procedures as of the end of the period covered by the Annual Report on 
Form 10-K.  Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded 
that our disclosure controls and procedures are effective for the purpose discussed above as of the end of the 
period covered by this Annual Report on Form 10-K.  There was no change in our internal control over financial 
reporting that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to 
materially affect, our internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING 

To the Stockholders’ of St. Mary Land & Exploration Company 

Management of the Company is responsible for establishing and maintaining adequate internal control 

over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, 
as amended.  The Company’s internal control over financial reporting is designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles.  The Company’s internal control over financial 
reporting includes those policies and procedures that: 

(i)  Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 

transactions and dispositions of the assets of the Company; 

(ii)  Provide reasonable assurance that transactions are recorded as necessary to permit preparation of 

financial statements in accordance with generally accepted accounting principles, and that receipts 
and expenditures of the Company are being made only in accordance with authorizations of 
management and directors of the Company; and 

(iii) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, 
use, or disposition of the Company’s assets that have a material effect on the financial statements. 

Because of the inherent limitations, internal controls over financial reporting may not prevent or detect 
misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 
controls may become inadequate because of the changes in conditions, or that the degree of compliance with the 
policies and procedures may deteriorate. 

Management assessed the effectiveness of the Company’s internal control over financial reporting as of 

December 31, 2009.  In making this assessment, management used the criteria set forth by the Committee of 
Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework. 

Based on our assessment and those criteria, management believes that the Company maintained effective 

internal control over financial reporting as of December 31, 2009. 

The Company’s independent registered public accounting firm has issued an attestation report on the 

Company’s internal controls over financial reporting.  That report immediately follows this report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of 
St. Mary Land & Exploration Company and Subsidiaries 
Denver, Colorado 

We have audited the internal control over financial reporting of St. Mary Land & Exploration Company and 
subsidiaries (the ―Company‖) as of December 31, 2009, based on criteria established in Internal Control – 
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.  The 
Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
Management’s Report on Internal Control Over Financial Reporting.  Our responsibility is to express an opinion 
on the Company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects.  Our audit 
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances.  We believe 
that our audit provides a reasonable basis for our opinion. 

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the 
company’s principal executive and principal financial officers, or persons performing similar functions, and 
effected by the company’s board of directors, management, and other personnel to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of the financial statements for external purposes 
in accordance with generally accepted accounting principles.  A company’s internal control over financial 
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable 
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide 
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of 
the company’s assets that could have a material effect on the financial statements. 

Because of the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may not be 
prevented or detected on a timely basis.  Also, projections of any evaluation of the effectiveness of the internal 
control over financial reporting to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate. 

In our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2009, based on the criteria established in Internal Control – Integrated Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated financial statements as of and for the year ended December 31, 2009, of the 
Company and our report dated February 23, 2010, expressed an unqualified opinion on those financial statements 
and included explanatory paragraphs regarding the Company’s adoption of new accounting standards.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of  
St. Mary Land & Exploration Company and Subsidiaries 
Denver, Colorado 

We have audited the accompanying consolidated balance sheets of St. Mary Land & Exploration Company and 
subsidiaries (the “Company”) as of December 31, 2009 and 2008, and the related consolidated statements of 
operations, stockholders’ equity and comprehensive income (loss), and cash flows for each of the three years in 
the period ended December 31, 2009.  These financial statements are the responsibility of the Company’s 
management.  Our responsibility is to express an opinion on the financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the 
accounting principles used and significant estimates made by management, as well as evaluating the overall 
financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position 
of St. Mary Land & Exploration Company and subsidiaries as of December 31, 2009 and 2008, and the results of 
their operations and their cash flows for each of the three years in the period ended December 31, 2009, in 
conformity with accounting principles generally accepted in the United States of America. 

As discussed in Note 1 to the consolidated financial statements, the Company changed its method of oil and gas 
reserve estimation and related required disclosures in 2009 with the implementation of new accounting guidance. 

As discussed in Note 5 to the consolidated financial statements, the Company changed its method of accounting 
for convertible debt in 2009. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the Company’s internal control over financial reporting as of December 31, 2009, based on the 
criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission, and our report dated February 23, 2010, expressed an unqualified 
opinion on the Company’s internal control over financial reporting.

In August 2009 and 2008, the Company granted 725,092 and 465,751 Performance Share Awards to
employees as equity-based compensation pursuant to the Company's Equity Incentive Compensation
Plan.  The total fair value of the issuances equaled $25.8 million and $12.3 million, respectively. 
The Company did not grant any Performance Share Awards in 2007.

For the years ended December 31,  2009, 2008, and 2007, the Company issued 241,745, 428,407, and 102,634
restricted stock units, respectively, to employees as equity-based compensation, pursuant to the
Company's Equity Incentive Compensation Plan.  The total fair value of the issuances was $5.8 million, $23.4
million, and $3.3 million, respectively. 

For the years ended December 31, 2009, 2008, and 2007, $109.0 million, $116.5 million, and $116.9 million,
respectively, are included as additions to oil and gas properties and accounts payable and accrued
expenses.  These oil and gas property additions are reflected in cash used in investing activities in the
periods that the payables are settled.  

For the years ended December 31, 2009, 2008, and 2007,  the Company issued 50,094, 23,113, and 32,504
shares, respectively, of common stock from treasury to its non-employee directors pursuant to the
Company's Equity Incentive Compensation Plan.  The Company recorded compensation expense related
to these issuances of approximately $688,000, $1,041,000, and $983,500 for the years ended December 31,
2009, 2008, and 2007, respectively.

For the years ended December 31, 2009, 2008 and 2007, the Company converted 215,700, 678,197, and 427,059
RSU's relating to awards granted in previous years.  The Company and a majority of grant participants
mutually agreed to net share settle the awards to cover income and payroll tax withholding as provided
for in the plan documents and award agreements.  As a result, the Company issued 156,252, 482,602, and
302,370 net shares of common stock associated with these grants for the years ended December 31, 2009, 2008,
and 2007, respectively.  The remaining 59,448, 195,595, and 124,689, shares were withheld to satisfy income and
payroll tax withholding obligations that occurred upon  the delivery of the shares underlying those RSU's.

In December 2008 the Company closed a transaction whereby it exchanged non-core oil and gas properties 
located in Coupee Parish, Louisiana fair valued at $30.4 million for an increased interest in properties 
located in Upton and Midland Counties, Texas and $17.6 million in cash.

In September 2008 the Company hired a new senior executive.  Upon commencement of employment, the
Company issued 15,496 shares of restricted stock awards to the senior executive, of which half vested
on December 15, 2009 and the remaining half will vest on December 15, 2010, provided that on such
vesting dates the executive is employed by the Company.  The total fair value of the issuance was
$600,005. 

In March 2007 the Company called the 5.75% Senior Convertible Notes for redemption.  All of the note
holders elected to convert the 5.75% Senior Convertible Notes to common stock.  As a result, the
Company issued 7,692,295 shares of common stock on March 16, 2007, in exchange for the $100 million
of 5.75% Senior Convertible Notes then outstanding.  The conversion was executed in accordance with
the conversion provisions of the original indenture.  Additionally, the conversion resulted in a $7.0
million decrease in non-current deferred income taxes payable and a corresponding increase in
additional paid-in capital that resulted from the recognition of the cumulative excess tax benefit earned
by the Company associated with the contingent interest feature of the notes.

ST. MARY LAND & EXPLORATION COMPANY AND SUBSIDIARIES  
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
DECEMBER 31, 2009 

Note 1 – Summary of Significant Accounting Policies 

Description of Operations 

St. Mary Land & Exploration Company (“St. Mary” or the “Company”) is an independent energy 

company engaged in the exploration, exploitation, development, acquisition, and production of natural gas and 
crude oil.  The Company’s operations are conducted entirely in the continental United States. 

Basis of Presentation 

The accompanying consolidated financial statements include the accounts of the Company and its wholly-

owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the 
United States and the instructions to Form 10-K and regulation S-X.  Subsidiaries that are not wholly-owned are 
accounted for using full consolidation by the equity or cost methods as appropriate.  Equity method investments 
are included in other noncurrent assets in the accompanying consolidated balance sheets.  Intercompany accounts 
and transactions have been eliminated.  In connection with the preparation of the consolidated financial statements 
of St. Mary and in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards 
Codification (“ASC”) Topic 855, “Subsequent Events” (“ASC Topic 855”) the Company evaluated subsequent 
events after the balance sheet date of December 31, 2009, through the filing of this report, February 23, 2010.  For 
additional information regarding ASC, please refer to the section titled Recently Issued Accounting Standards 
within Note 1 – Summary of Significant Accounting Policies. 

On January 1, 2009, the adoption of new authoritative accounting guidance under FASB ASC Topic 470, 

“Debt” (“ASC Topic 470”) required retrospective application.  As a result, prior period balances presented have 
been adjusted to reflect the period-specific effects of applying ASC Topic 470.  Please refer to Note 5 – Long-
term Debt for additional information regarding adoption. 

Use of Estimates in the Preparation of Financial Statements 

The preparation of financial statements in conformity with accounting principles generally accepted in the 
United States requires management to make estimates and assumptions that affect the reported amounts of oil and 
gas reserves, assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial 
statements, and the reported amounts of revenues and expenses during the reporting period.  Actual results could 
differ from those estimates.  Estimates of proved oil and gas reserve quantities provide the basis for the 
calculation of depletion, depreciation, and amortization (“DD&A”), impairment of proved properties, and the Net 
Profits Interest Bonus Plan (“Net Profits Plan”) liability, each of which represents a significant component of the 
accompanying consolidated financial statements. 

Cash and Cash Equivalents 

The Company considers all liquid investments purchased with an initial maturity of three months or less 
to be cash equivalents.  The carrying value of cash and cash equivalents approximates fair value due to the short-
term nature of these instruments. 

Short-term Investments 

As of December 31, 2008, the Company held $1.0 million of short-term investments, which consists of a 

certificate of deposit.  Securities categorized as held-to-maturity are stated at amortized cost whereas available-
for-sale securities are marked-to-market.  As of December 31, 2009, the Company held no short-term 
investments.   

F-7 

 
Accounts Receivable and Concentration of Credit Risk 

The Company’s accounts receivables consist mainly of receivables from oil and gas purchasers and from 

partners with interests in common properties operated by the Company.  Although diversified among many 
companies, collectability is dependent upon the financial wherewithal of each individual company and is 
influenced by the general economic conditions of the industry.  The Company records an allowance for doubtful 
accounts on a case by case basis once there is evidence that collection is not probable.  Receivables are not 
collateralized.  As of December 31, 2009, the Company had no allowance for doubtful accounts recorded.  As of 
December 31, 2008, the Company had $16.8 million recorded as allowance for doubtful accounts.  For additional 
discussion on allowance for doubtful accounts, please refer to Note 14 – SemGroup Bankruptcy. 

The Company has accounts with separate banks in Denver, Colorado; Shreveport, Louisiana; Franklin, 

Louisiana; Tulsa, Oklahoma; and Billings, Montana.  At December 31, 2009, and 2008, the Company had 
$2.3 million and $4.8 million, respectively, invested in money market funds and overnight investment sweep 
accounts.  The difference between the investment amount and the cash and cash equivalents amount on the 
accompanying consolidated balance sheets represents uncleared disbursements and non-interest-bearing checking 
accounts.  The Company’s policy is to invest in highly-rated instruments and to limit the amount of credit 
exposure at each individual institution. 

The Company currently uses 6 separate counterparties for its oil and gas commodity derivatives.  The 

counterparties to the Company’s derivative instruments are highly-rated entities with corporate credit ratings at or 
exceeding BBB+ and Baa1 classifications by Standard & Poor’s and Moody’s, respectively.  Ratings represent 
minimum investment grade ratings. 

Oil and Gas Producing Activities 

The Company follows the successful efforts method of accounting for its oil and gas properties.  Under 

this method of accounting, all property acquisition costs and costs of exploratory and development wells are 
capitalized when incurred, pending determination of whether the well found proved reserves.  If an exploratory 
well does not find proved reserves, the costs of drilling the well are charged to expense.  Exploratory dry hole 
costs are included in cash flows from investing activities as part of capital expenditures within the accompanying 
consolidated statements of cash flows.  The costs of development wells are capitalized whether those wells are 
successful or unsuccessful. 

Geological and geophysical costs and the costs of carrying and retaining unproved properties are 
expensed as incurred.  DD&A of capitalized costs related to proved oil and gas properties is calculated on a pool-
by-pool basis using the units-of-production method based upon proved reserves.  The computation of DD&A 
takes into consideration restoration, dismantlement, and abandonment costs as well as the anticipated proceeds 
from salvaging equipment.  As of December 31, 2009, and 2008, the Company’s capitalized proved oil and gas 
properties included $77.8 million and $102.3 million, respectively, of estimated salvage value. 

The Company follows guidance under FASB ASC Topic 932, “Extractive Activities – Oil and Gas” 

(“ASC Topic 932”) when accounting for suspended well costs.  For additional discussion, please see the heading 
Suspended Well Costs in Note 15 –Oil and Gas Activities. 

Impairment of Proved and Unproved Properties 

Producing oil and gas property costs are evaluated for impairment and reduced to fair value, which is 

expected future discounted cash flows, if the sum of expected undiscounted future cash flows is less than net book 
value pursuant to FASB ASC Topic 360, “Property, Plant, and Equipment” (“ASC Topic 360”).  Expected future 
cash flows are calculated on all proved reserves using a discount rate and price forecasts selected by the 
Company’s management.  The discount rate is a rate that management believes is representative of current market 
conditions.  The price forecast is based on NYMEX strip pricing for the first five years, adjusted for basis 
differentials.  At the end of the first five years a flat terminal price is used.  Future operating costs are also 

F-8 

 
adjusted as deemed appropriate for these estimates.  An impairment write down is recorded on unproved property 
when the Company determines that either the property will not be developed or the carrying value is not 
realizable. 

For the years ended December 31, 2009, and 2008, the Company recorded proved property impairment 

expense of $174.8 million and $302.2 million, respectively.  The Company did not incur any proved property 
impairment write-downs during 2007.  In the first quarter of 2009, the Company incurred impairment on proved 
properties of $97.3 million related to assets located in the Mid-Continent region due to a significant decrease in 
the market price for natural gas and wider than normal differentials.  In the fourth quarter of 2009, the Company 
incurred impairment on proved properties of $20.4 million related to assets located in the ArkaLaTex region due 
to decreased natural gas prices and engineering revisions.  The Company incurred an additional impairment on 
proved properties of $14.0 million during the year related to the write-down of certain assets located in the Gulf 
of Mexico in which the Company is relinquishing its ownership interests in order to satisfy its abandonment 
obligations.  Approximately $154.0 million of the 2008 impairment write-down relates to the Olmos assets in 
South Texas that were acquired as part of the 2007 Rockford and Catarina acquisitions.  The remaining 2008 
impairment came from proved properties in the Gulf of Mexico, the Greater Green River Basin in Wyoming, and 
the Company’s Hanging Women Basin coalbed methane project. 

For the years ended December 31, 2009, 2008, and 2007, the Company recorded expense related to the 

abandonment and impairment of unproved properties of $45.4 million, $39.0 million, and $4.8 million, 
respectively.  The largest specific components of the 2009 impairment related to the Floyd Shale acreage located 
in Mississippi and acreage in Oklahoma.  The largest specific component of the 2008 impairment related to 
acreage within the Olmos shallow gas formation in South Texas. 

Sales of Proved and Unproved Properties 

The sale of a partial interest in a proved oil and gas property is accounted for as normal retirement, and no 

gain or loss is recognized as long as the treatment does not significantly affect the units-of-production depletion 
rate.  A gain or loss is recognized for all other sales of producing properties and is included in the accompanying 
consolidated statements of operations. 

The sale of a partial interest in an unproved property is accounted for as a recovery of cost when 
substantial uncertainty exists as to the ultimate recovery of the cost applicable to the interest retained.  A gain on 
the sale is recognized to the extent that the sales price exceeds the carrying amount of the unproved property.  A 
gain or loss is recognized for all other sales of nonproducing properties and is included in the accompanying 
consolidated statements of operations. 

Materials Inventory 

The Company’s materials inventory is primarily comprised of tubular goods to be used in future drilling 

or repair operations.  Materials inventory is valued at the lower of cost or market and totaled $24.5 million and 
$40.5 million at December 31, 2009, and 2008, respectively.  The Company incurred net materials inventory 
write-downs for year ended December 31, 2009, of $14.2 million as a result of the decrease in value of tubular 
goods.  There were no materials inventory write-downs for the years ended December 31, 2008, and 2007. 

Assets Held for Sale 

In accordance with ASC Topic 360, any properties held for sale as of the date of presentation of a balance 

sheet have been classified as assets held for sale and are separately presented on the accompanying consolidated 
balance sheets at the lower of net book value or fair value less the cost to sell.  The asset retirement obligation 
liabilities related to such properties have been reclassified to asset retirement obligations associated with oil and 
gas properties held for sale in the consolidated balance sheets.  For additional discussion on assets held for sale, 
please refer to Note 3 – Acquisitions, Divestitures, and Assets Held for Sale. 

F-9 

 
Other Property and Equipment 

Other property and equipment such as office furniture and equipment, buildings, and computer hardware 
and software are recorded at cost.  Costs of renewals and improvements that substantially extend the useful lives 
of the assets are capitalized.  Maintenance and repair costs are expensed when incurred.  Depreciation is 
calculated using the straight-line method over the estimated useful lives of the assets which range from three to 
thirty years.  When other property and equipment is sold or retired, the capitalized costs and related accumulated 
depreciation are removed from the accounts. 

Goodwill 

Goodwill is measured as the excess of the acquisition costs over the sum of the amounts assigned to the 

identifiable assets acquired less liabilities assumed.  Goodwill was recorded as a result of the acquisition of Agate 
Petroleum, Inc. in January 2005.  The Company conducted an impairment review annually or more frequently if 
impairment indicators arose.  The Company fully impaired its goodwill at December 31, 2008. 

Restricted Cash 

Proceeds from certain sales of oil and gas properties are held in escrow and restricted for future 
acquisitions under tax-free exchange agreements.  These funds are invested in money market funds consisting of 
corporate commercial paper, repurchase agreements, and U.S. Treasury obligations and are carried at cost, which 
approximates fair market value. 

Intangible Assets 

As of December 31, 2009, and 2008, the Company’s other noncurrent assets in the accompanying 

consolidated balance sheets include $380,000 and $1.4 million, respectively, of intangible assets.  These assets 
arise from acquired oil and gas sale contracts with favorable pricing terms.  They do not qualify as derivatives or 
hedges.  Intangible assets of the Company are amortized using the units-of-production method and are evaluated 
for impairment if such indicators arise.   

Cash Settlement Balancing 

The Company uses the sales method of accounting for gas revenue whereby sales revenue is recognized 

on all gas sold to purchasers, regardless of whether the sales are proportionate to the Company’s ownership in the 
property.  An asset or liability is recognized to the extent that there is an imbalance in excess of the remaining gas 
reserves on the underlying properties.  The Company’s gas imbalance position at December 31, 2009, and 2008, 
respectively, resulted in the recording of $1.8 million to accounts receivable as of both dates and $1.2 million and 
$1.1 million, respectively, to accounts payable. 

Derivative Financial Instruments 

The Company seeks to manage or reduce commodity price risk on acquisitions of producing properties 

and other production by hedging cash flows.  The Company intends for derivative instruments used for this 
purpose to qualify as and to be designated as cash flow hedges.  The Company seeks to minimize its basis risk 
and indexes the majority of its oil hedges to NYMEX prices and the majority of its gas hedges to various regional 
index prices associated with pipelines in proximity to the Company’s areas of gas production.  For additional 
discussion on derivatives, please see Note 10 – Derivative Financial Instruments.

Net Profits Plan 

The Company records the estimated fair value of future payments under the Net Profits Plan as a 

noncurrent liability in the accompanying consolidated balance sheets.  The estimated liability is a discounted 
calculation and has underlying assumptions including estimates of oil and gas reserves, recurring and workover 
lease operating expense, production and ad valorem tax rates, present value discount factors, and pricing 
assumptions.  The estimates the Company uses in calculating the long-term liability are adjusted from period-to-
period based on the most current information attributable to the underlying assumptions.  Changes in the 
estimated liability of future payments associated with the Net Profits Plan are recorded as increases or decreases 
to expense in the current period as a separate line item in the accompanying consolidated statements of operations 
as these changes are considered changes in estimates.   

The distribution amounts due to participants and payable in each period under the Net Profits Plan as cash 

compensation related to periodic operations are recognized as compensation expense and are included within 
general and administrative expense and exploration expense in the accompanying consolidated statements of 
operations.  The corresponding current liability is included in accounts payable and accrued expenses in the 
accompanying consolidated balance sheets.  This treatment provides for a consistent matching of cash expense 
with net cash flows from the oil and gas properties in each respective pool of the Net Profits Plan.  For additional 
discussion, please refer to the heading Net Profits Plan in Note 7 – Compensation Plans. 

Asset Retirement Obligations 

The Company recognizes an estimated liability for future costs associated with the abandonment of its oil 

and gas properties.  A liability for the fair value of an asset retirement obligation and corresponding increase to 
the carrying value of the related long-lived asset are recorded at the time a well is completed or acquired.  The 
increase in carrying value is included in proved oil and gas properties in the accompanying consolidated balance 
sheets.  The Company depletes the amount added to proved oil and gas property costs and recognizes expense in 
connection with the accretion of the discounted liability over the remaining estimated economic lives of the 
respective oil and gas properties.  For additional discussion, please refer to Note 9 – Asset Retirement 
Obligations. 

Revenue Recognition 

The Company derives revenue primarily from the sale of produced natural gas and crude oil.  The 

Company reports revenue as the gross amount received before taking into account production taxes and 
transportation costs, which are reported as separate expenses.  Revenue is recorded in the month the Company’s 
production is delivered to the purchaser, but payment is generally received between 30 and 90 days after the date 
of production.  No revenue is recognized unless it is determined that title to the product has transferred to the 
purchaser.  At the end of each month, the Company estimates the amount of production delivered to the purchaser 
and the price the Company will receive.  The Company uses its knowledge of its properties, their historical 
performance, New York Mercantile Exchange (“NYMEX”) and local spot market prices, quality and 
transportation differentials, and other factors as the basis for these estimates. 

Major Customers 

During 2009 the Company had one customer individually account for 12 percent of the Company’s total 

oil and gas production revenue.  During 2008 and 2007 no customer individually accounted for more than ten 
percent of the Company’s total oil and gas production revenue. 

F-11 

 
 
 
Stock Based Compensation 

At December 31, 2009, the Company had stock-based employee compensation plans that included RSUs, 
PSAs, stock awards, and stock options issued to employees and non-employee directors as more fully described in 
Note 7- Compensation Plans.  Stock options were last issued in December 2004 and were fully vested as of 
December 31, 2008.  The Company records expense associated with the fair value of stock-based compensation in 
accordance with FASB ASC Topic 718, “Compensation – Stock Compensation” (“ASC 718”).  The Company 
used the modified-prospective method to record compensation expense associated with stock options that were 
outstanding and unvested as of January 1, 2006.  The Company records compensation expense associated with the 
issuance of RSUs and PSAs based on the estimated fair value of these grants as determined at the time of grant. 

Income Taxes 

The Company accounts for deferred income taxes whereby deferred tax assets and liabilities are 

recognized based on the tax effects of temporary differences between the carrying amount on the financial 
statements and the tax basis of assets and liabilities, as measured using current enacted tax rates.  These 
differences will result in taxable income or deductions in future years when the reported amount of the asset or 
liabilities are recorded or settled, respectively.  When appropriate the Company records a valuation allowance to 
reduce deferred tax assets. 

Earnings per Share 

Basic net income per common share is calculated by dividing net income available to common 
stockholders by the weighted-average basic common shares outstanding for the respective period.  The weighted-
average basic common shares outstanding include vested RSUs.  The basic earnings per share calculations reflect 
the impact of any repurchases of shares of common stock made by the Company. 

Diluted net income per common share of stock is calculated by dividing adjusted net income by the 
weighted-average diluted common shares outstanding, which includes the effect of potentially dilutive securities.  
Potentially dilutive securities for the diluted earnings per share calculation consist of unvested RSUs, in-the-
money outstanding stock options to purchase the Company’s common stock, contingent PSAs, and shares into 
which the 3.50% Senior Convertible Notes are convertible. 

The treasury stock method is used to measure the dilutive impact of stock options, RSUs, 3.50% Senior 
Convertible Notes, and PSAs.  In accordance with FASB ASC Topic 260, “Earnings Per Share,” when there is a 
loss from continuing operations, all potentially dilutive shares will be anti-dilutive.  As such, there were no 
dilutive shares for the year ended December 31, 2009.  The following table details the weighted-average dilutive 
and anti-dilutive securities related to stock options, RSUs, and PSAs for the years presented:

The Company’s 3.50% Senior Convertible Notes, which were issued on April 4, 2007, have a net-share 
settlement right whereby each $1,000 principal amount of notes may be surrendered for conversion to cash in an 
amount equal to the principal amount and, if applicable, shares of common stock for the amount in excess of the 
principal amount.  The 3.50% Senior Convertible Notes have not been dilutive for any reporting period that they 
have been outstanding and therefore do not impact the diluted earnings per share calculation for the periods ended 
December 31, 2009, 2008, and 2007.

On August 1, 2009, and 2008, the Company granted 725,092 and 465,751 PSAs, respectively, for the 

three-year performance periods ending June 30, 2012, and 2011.  At the end of each grant’s three-year 
performance period, a multiplier will be applied to all vested PSAs to determine the number of common shares 
issued.  The number of common shares issued is determined based on the Company’s absolute stock price 
performance and a comparison of the Company’s stock price performance to an index of its peers.  The number of 
potentially dilutive shares related to the PSAs is based on the number of shares, if any, which would be issuable if 
the end of the reporting period was the end of the contingency period.  Based on the Company’s cumulative total 
shareholder return (“TSR”) and the relative measure of the Company’s TSR compared with the cumulative TSR 
of the index of its peers, there would have been potentially dilutive shares related to PSAs as of 
December 31, 2009.  However, no dilutive shares related to PSAs were included in the diluted earnings per share 
calculation for the year ended December 31, 2009, because the Company recorded a loss for the period.  There 
were no potentially dilutive shares related to PSAs included in the diluted earnings per share calculation for the 
years ended December 31, 2008, and 2007.  For additional discussion on PSAs, please see the heading 
Performance Share Awards Under the Equity Incentive Compensation Plan in Note 7 – Compensation Plans.

Fair Value of Financial Instruments 

The Company’s financial instruments including cash and cash equivalents, accounts receivable, and 

accounts payable are carried at cost, which approximates fair value due to the short-term maturity of these 
instruments.  The recorded value of the Company’s credit facility approximates its fair value as it bears interest at 
a floating rate.  The Company had $188.0 million and $300.0 million in loans outstanding under its revolving 
credit agreement as of December 31, 2009, and 2008, respectively.  The Company’s 3.50% Senior Convertible 
Notes due 2027 (the “3.50% Senior Convertible Notes”) are recorded at cost, and the fair value is disclosed in 
Note 5 – Long-Term Debt.  The Company has derivative financial instruments that are recorded at fair value and 
changes in fair value run through accumulated other comprehensive income in the accompanying consolidated 
balance sheets to the extent they are effective.  Considerable judgment is required to develop estimates of fair 
value.  The estimates provided are not necessarily indicative of the amounts the Company would realize upon the 
sale or refinancing of such instruments. 

Industry Segment and Geographic Information 

The Company operates exclusively in the exploration and production segment.  All of the Company’s 
operations are conducted in the continental United States.  The Company reports as a single industry segment.  
The Company’s gas marketing department provides mostly internal services and acts as the first purchaser of 
natural gas and natural gas liquids produced by the Company in certain cases.  We consider the Company’s 
marketing function as ancillary to the Company’s oil and gas producing activities.  The amount of income these 
operations generate from marketing gas produced by third parties is not material to the Company’s financial 
position, and segmentation of such activity would not provide a better understanding of the Company’s 
performance.  However, gross revenue and expense related to marketing activities for gas produced by third 
parties are presented discretely in the accompanying consolidated statements of operations.

Off-Balance Sheet Arrangements 

As part of its ongoing business, the Company has not participated in transactions that generate 
relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured 
finance or special purpose entities (“SPEs”), which would have been established for the purpose of facilitating 
off-balance sheet arrangements or other contractually narrow or limited purposes.  As of and up to 
December 31, 2009, the Company has not been involved in any unconsolidated SPE transactions. 

The Company evaluates its transactions to determine if any variable interest entities exist.  If it is 

determined that St. Mary is the primary beneficiary of a variable interest entity, that entity is consolidated into 
St. Mary. 

Recently Issued Accounting Standards 

New authoritative accounting guidance under FASB ASC Topic 105, “Generally Accepted Accounting 

Principles” (“ASC Topic 105”) established the FASB Accounting Standards Codification as the source of 
authoritative U.S. GAAP recognized by the FASB to be applied to nongovernmental entities.  ASC Topic 105 
also states that rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under federal 
securities laws are also sources of authoritative GAAP for SEC registrants.  ASC Topic 105 supersedes existing 
FASB, American Institute of Certified Public Accountants, Emerging Issues Task Force, and related literature.  
All other accounting literature is considered non-authoritative.  ASC Topic 105 changes the way the Company 
cites authoritative guidance within the Company’s financial statements and accounting policies.  The new 
authoritative guidance under ASC Topic 105 became effective for periods ending on or after September 15, 2009, 
and did not have a material impact on the Company’s consolidated financial statements. 

New authoritative accounting guidance under FASB ASC Topic 805, “Business Combinations” (“ASC 

Topic 805”) requires the acquiring entity in a business combination to recognize and measure all assets and 
liabilities assumed in the transaction and any non-controlling interest in the acquiree at fair value as of the 
acquisition date.  ASC Topic 805 changes the way the Company accounts for acquisitions of proved oil and gas 
properties.  Such acquisitions will now be treated as business combinations, which will require transaction costs 
to be expensed as incurred, may generate gains or losses due to fair value changes between the effective and 
closing dates of acquisitions, and will require possible recognition of goodwill given differences between the 
purchase price and fair value of acquired assets.  ASC Topic 805 further amends the initial recognition and 
measurement, subsequent measurement and accounting, and disclosures of assets and liabilities arising from 
contingencies in a business combination.  The new authoritative guidance under ASC Topic 805 became effective 
for the Company on January 1, 2009, and the impact on the Company’s consolidated financial statements will 
largely be dependent on the size and nature of the business combinations completed.  The Company has not made 
any significant acquisitions of oil and gas properties since adoption. 

New authoritative accounting guidance under FASB ASC Topic 810, “Consolidation” 

(“ASC Topic 810”) established accounting and reporting standards that require non-controlling interests to be 
reported as a component of equity along with any changes in the parent’s ownership interest.  The new 
authoritative guidance under ASC Topic 810 became effective for the Company on January 1, 2009, and did not 
have a material impact on the Company’s consolidated financial statements. 

New authoritative accounting guidance under FASB ASC Topic 825, “Financial Instruments” (“ASC 

Topic 825”) requires the Company to include disclosures about the fair value of its financial instruments 
whenever it issues financial information for interim reporting periods and annual reporting periods, whether 
recognized or not recognized in the consolidated balance sheets.  The new authoritative guidance under ASC 
Topic 825 became effective for the Company on April 1, 2009, and did not have a material impact on the 
Company’s consolidated financial statements. 

F-15 

 
 
 
New authoritative accounting guidance under ASC Topic 855 established general standards of accounting 

for and disclosures of events that occur after the balance sheet date but before financial statements are issued or 
are available to be issued.  ASC Topic 855 requires companies to disclose the date through which the Company 
evaluated subsequent events, the basis for that date, and whether that date represents the date the financial 
statements were issued.  The new authoritative guidance under ASC Topic 855 became effective for the Company 
on April 1, 2009, and did not have a material impact on the Company’s consolidated financial statements. 

In December 2008 the SEC published the final rules and interpretations updating its oil and gas reporting 

requirements.  Many of the revisions are updates to definitions in the existing oil and gas rules to make them 
consistent with the Petroleum Resource Management System, which was developed by several petroleum industry 
organizations and is a widely accepted standard for the management of petroleum resources.  Key revisions 
include a requirement to use 12-month average pricing determined by averaging the first of the month prices for 
the preceding 12 months rather than year-end pricing for estimating proved reserves, the ability to include 
nontraditional resources in reserves, the ability to use new technology for determining proved reserves, and 
permitting disclosure of probable and possible reserves.  The Company adopted these new rules and 
interpretations as of December 31, 2009. 

The FASB aligned ASC Topic 932, with all of the aforementioned SEC requirements by issuing ASC 
Update 2010-03.  The new authoritative guidance became effective for the Company’s 2009 Annual Report on 
Form 10-K and has been fully adopted by the Company as of December 31, 2009. 

In January 2010 the FASB issued ASC Update 2010-06, “Fair Value Measurements and Disclosures” 

(“ASC Update 2010-06”) that requires additional disclosures surrounding transfers in and out of Levels 1 and 2, 
inputs and valuation techniques used to value Level 2 and 3 measurements, and push down of previously 
prescribed fair value disclosures to each class of asset and liability for Levels 1, 2, and 3.  This new authoritative 
guidance is effective for interim and annual reporting periods beginning after December 15, 2009.  The Company 
will apply the new authoritative guidance in the Company’s March 31, 2010, Quarterly Report on Form 10-Q.  
ASC Update 2010-06 also requires that purchases, sales, issuances, and settlements for Level 3 measurements be 
disclosed.  This portion of the new authoritative guidance is effective for interim and annual reporting periods 
beginning after December 15, 2010.  The Company will apply this new authoritative guidance in the Company’s 
March 31, 2011, Quarterly Report on Form 10-Q.  The adoption of ASC Update 2010-06 will not have a material 
impact on the Company’s financial statements. 

Please refer to Note 5 – Long-term Debt, Note 8 – Pension Benefits, Note 10 - Derivative Financial 
Instruments, Note 11 – Fair Value Measurements, and Note 16 – Disclosures about Oil and Gas Producing 
Activities for additional information on the recent adoption of new authoritative accounting guidance.

In December 2009 the Company completed the divestiture of certain non-strategic coalbed methane 

properties located in the Hanging Woman Basin in the Rocky Mountain region.  The cash received at closing, 
including a $2.0 million deposit, net of commission costs, was $23.3 million.  The final sales price is subject to 
normal post-closing adjustments and is expected to be finalized during the second quarter of 2010.  The estimated 
gain on sale related to the divestiture is approximately $12.9 million and may be impacted by the previously 
mentioned post-closing adjustments. The Company determined that this sale did not qualify for discontinued 
operations accounting under FASB ASC Topic 205, “Presentation of Financial Statements” (“ASC Topic 205”). 

Greater Green River Basin Divestiture 

In June 2008 the Company completed the divestiture of certain non-strategic gas properties located in the 

Greater Green River Basin in the Rocky Mountain region as the second step of a reverse 1031 exchange.  The 
cash received at closing, net of commission costs, was $21.9 million.  The final sales price is subject to normal 
post-closing adjustments and is expected to be finalized during 2010.  The estimated gain on sale related to the 
divestiture is approximately $900,000, net of commission costs and Net Profit Plan payments, and may be 
impacted by the previously mentioned post-closing adjustments.  The Company determined that this sale did not 
qualify for discontinued operations accounting under ASC Topic 205. 

Abraxas Divestiture 

In January 2008 the Company completed the divestiture of certain non-strategic oil and gas properties as 

the second step of a reverse 1031 exchange.  The sold properties were located primarily in the Rocky Mountain 
and Mid-Continent regions, and were sold to Abraxas Petroleum Corporation and Abraxas Operating, LLC.  The 
final sales price, net of commission costs, was $129.4 million.  The final gain on sale related to the divestiture was 
approximately $53.4 million, net of commission costs and Net Profit Plan payments.  The Company determined 
that this sale did not qualify for discontinued operations accounting under ASC Topic 205.

Carthage Acquisition 

In March 2008, the Company acquired oil and gas properties as the first step of a reverse 1031 exchange.  

These properties are located primarily in the Carthage Field in Panola County, Texas and were purchased for 
$49.2 million in cash.  After normal purchase price adjustments, the Company allocated $29.0 million to proved 
oil and gas properties, $20.6 million to unproved oil and gas properties, and a net $215,000 to other liabilities.  
The Company also recorded a $165,000 asset retirement obligation liability associated with the acquired 
properties.  The acquisition was funded with cash on hand and borrowings under the Company’s existing credit 
facility.  During the second quarter of 2008, the Company acquired additional interests in the majority of these 
properties for $8.1 million. 

Assets Held for Sale 

In accordance with ASC Topic 360, assets are classified as held for sale when the Company commits to a 

plan to sell the assets and there is reasonable certainty that the sale will take place within one year.  Upon 
classification as held for sale, long-lived assets are no longer depreciated or depleted and a measurement for 
impairment is performed to expense any excess of carrying value over fair value less costs to sell.  Subsequent 
changes to estimated fair value less the cost to sell will impact the measurement of assets held for sale for assets 
for which fair value is determined to be less than the carrying value of the assets. 

As of December 31, 2009, the accompanying consolidated balance sheets includes $145.4 million in book 
value of assets held for sale, net of accumulated depletion, depreciation, and amortization.  The corresponding asset 
retirement obligation liability of $18.1 million is also separately presented.  The above assets held for sale and asset 
retirement obligation liability amounts include certain non-core properties located primarily in the Rocky Mountain 
region that the Company began marketing in the third quarter of 2009, as well as a new package of properties 
located in our South Texas and Gulf Coast region.  The Company determined that these sales do not qualify for 
discontinued operations accounting under ASC Topic 205. 

In December 2009, St Mary reached an agreement for the partial sale of its previously announced 

divestiture package, of certain non-strategic oil and gas properties located in the Rocky Mountain region to 
Legacy Reserves Operating LP.  The transaction has an effective date of November 1, 2009.  Subsequent to year 
end, on February 17, 2010, the Company completed this divestiture.  Total cash received, before commission 
costs, was $125.2 million, of which $6.5 million was received as a deposit in December 2009 and is separately 
presented on the accompanying consolidated balance sheets.  The cash received is subject to normal post-closing 
adjustments and settlements. 

Subsequent to year end, St Mary reached an agreement for the sale of the North Dakota portion of its 
previously announced divestiture package of certain non-strategic oil and gas properties located in the Rocky 
Mountain region to Sequel Energy Partners L.P. for $137.0 million in cash, subject to normal closing and post-
closing adjustments.  The agreement has an effective date of November 1, 2009, and is anticipated to close in 
March 2010, subject to customary closing conditions. 

In the third quarter of 2009, St. Mary reclassified a portion of the assets previously classified as held for sale 
to assets held and used, as these assets were no longer being actively marketed.  In accordance with ASC Topic 360, 
the Company must measure the assets at the lower of the assets carrying amount before the assets were classified as 
held for sale, adjusted for any depreciation and depletion expense that would have been recognized had the assets 
been continuously classified as held and used, or the assets fair value at the subsequent date that the decision not 
to actively market the assets was determined.  As a result of this measurement the Company recognized a 
$9.8 million loss on unsuccessful sale of properties, which is included in gain (loss) on divestiture activity in the 
accompanying consolidated statements of operations.

At December 31, 2009, the Company had estimated state net operating loss carryforwards of 
approximately $259 million expiring between 2010 and 2019.  The Company has a federal AMT credit carry 
forward of $2.1 million which will not expire, and other state tax credits of $285,000 which expire between 2010 
and 2029.  The majority of the Company’s valuation allowance relates to state net operating loss carryforwards,

state tax credits, and state and federal income tax benefit amounts which the Company anticipates will expire 
before they can be utilized.  Permanent items included in the calculation of income tax for certain states are 
anticipated to impact the Company’s ability to deduct operating losses and realize federal income tax deduction 
benefits in certain states and the Company has adjusted its valuation allowances accordingly.  A small portion of 
the valuation allowance relates to the Net Profits Plan liability and reflects an estimate of future executive 
compensation that may not be deductible for income tax purposes when future cash payments occur under the 
plan. 

Federal income tax expense differs from the amount that would be provided by applying the statutory 

U.S. federal income tax rate to income before income taxes primarily due to the effect of state income taxes, 
percentage depletion, the estimated effect of the domestic production activities deduction, 2008 impairment of 
goodwill, and other permanent differences, as follows:

Acquisitions, drilling, and basis differentials impacting the prices received for crude oil and natural gas 
affect apportionment of taxable income to the states where the Company owns property.  As its apportionment 
factors change, the Company’s blended state income tax rate changes.  This change, when applied to the 
Company’s total temporary difference, impacts the total income tax reported in the current year and is reflected in 
state taxes in the table above.  Items affecting state apportionment factors are evaluated after completion of the 
prior year income tax return and when significant acquisitions or dispositions are closed during the current year. 

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and in various 
states.  With few exceptions, the Company is no longer subject to U.S. federal or state income tax examinations 
by these tax authorities for years before 2006.  The Internal Revenue Service initiated an audit of the Company’s 
2005 tax year in 2008 and concluded the audit in the first quarter of 2009 with a refund to the Company of 
$278,000 plus interest of $41,000.  Related amended state income tax returns were filed in the second quarter of 
2009.  There was no change to the provision for income tax expense as a result of the examination.  In the fourth 
quarter of 2009 the Company received a refund of $5.0 million dollars related to its 2008 income tax return.  At 
December 31, 2009 the Company is awaiting a $5.5 million dollar refund related to filing an amended return for 
its 2006 tax year reflecting a net operating loss carry back from the Company’s 2008 tax year.  The Company’s 
remaining receivable balance reflects its intention to carry back a net operating loss generated in 2009 to prior 
years. 

At December 31, 2008, the Company recognized an impairment of goodwill recorded as part of the Agate 

Petroleum, Inc. acquisition in 2005.  The tax benefit is not calculated upon the recognition of this expense.  For 
additional discussion please refer to the section titled Goodwill within Note 1 – Summary of Significant 
Accounting Policies.  This resulted in a 2.2 percent increase in the Company’s effective tax rate for the year ended 
December 31, 2008.  The Company received $1.0 million in the first quarter of 2008 for income tax refunds and 
accrued interest resulting from a carry-over of minimum tax credits to its 2003 tax year.

The Company adopted the uncertainty provision of FASB ASC Topic 740, “Income Taxes” on January 1, 

2007.  There was no financial statement adjustment required as a result of adoption.  At adoption, the Company 
had a long-term liability for an unrecognized tax benefit of $1.0 million and accumulated interest liability of 
$92,000.  The entire amount of unrecognized tax benefit would affect the Company’s effective tax rate if 
recognized.  Interest expense in the 2009 accompanying consolidated statements of operation includes a nominal 
$12,000 associated with income tax.  Penalties associated with income tax are recorded in general and 
administrative expense in the accompanying consolidated statements of operations.  There were no penalties 
associated with income tax recorded for the year ended December 31, 2009, 2008, and 2007.

Note 5 – Long-term Debt 

Revolving Credit Facility 

The Company executed a Third Amended and Restated Credit Agreement on April 14, 2009.  This 
amended revolving credit facility replaced the previous facility.  The Company incurred $11.1 million of deferred 
financing costs in association with the amended credit facility.  Borrowings under the facility are secured by a 
pledge, in favor of the lenders, of collateral that includes the majority of the Company’s oil and gas properties.  
The credit facility specifies a maximum loan amount of $1.0 billion and has a maturity date of July 31, 2012.  The 
authorized borrowing base under the credit facility is subject to regular semi-annual redeterminations.  The 
borrowing base redetermination process considers the value of St. Mary’s oil and gas properties and other assets, 
as determined by the bank syndicate.  On September 29, 2009, the lending group redetermined and maintained the 
Company’s reserve-backed borrowing base under the credit facility at an amount of $900 million.  The Company 
has an aggregate commitment amount of $678 million under the credit facility.  The Company must comply with 
certain covenants under the terms of its credit facility agreement, including the limitation of the Company’s 
annual dividend rate to no more than $0.25 per share.  The Company is in compliance with all covenants under 
the credit facility as of December 31, 2009, and through the date of this filing.  Interest and commitment fees are 
accrued based on the borrowing base utilization grid below.  Eurodollar loans accrue interest at the London 
Interbank Offered Rate (“LIBOR”) plus the applicable margin from the utilization table, and Alternative Base 
Rate (“ABR”) and swingline loans accrue interest at Prime plus the applicable margin from the utilization table.  
Commitment fees are accrued on the unused portion of the aggregate commitment amount and are included in 
interest expense in the accompanying consolidated statements of operations.

The Company had $211.0 million, $188.0 million, and $300.0 million in outstanding loans under its 
revolving credit agreement on February 16, 2010, December 31, 2009, and 2008, respectively.  The Company had 
$467.0 million, $489.4 million, and $200.0 million of available borrowing capacity under this facility as of 
February 16, 2010, December 31, 2009, and 2008, respectively.  The Company had a single letter of credit 
outstanding in the amount of $569,000 as of December 31, 2009.  This letter of credit reduced the amount 
available under the commitment amount on a dollar-for-dollar basis.  There was no letter of credit outstanding as 
of February 16, 2010. 

3.50% Senior Convertible Notes Due 2027 

On April 4, 2007, the Company issued $287.5 million in aggregate principal amount of 3.50% Senior 

Convertible Notes.  The 3.50% Senior Convertible Notes mature on April 1, 2027, unless converted prior to 
maturity, redeemed, or purchased by the Company.  The 3.50% Senior Convertible Notes are unsecured senior 
obligations and rank equal in right of payment with all of the Company’s existing and any future unsecured senior 
debt and are senior in right of payment to any future subordinated debt. 

Holders may convert their notes based on a conversion rate of 18.3757 shares of the Company’s common 
stock per $1,000 principal amount of the 3.50% Senior Convertible Notes (which is equal to an initial conversion 
price of approximately $54.42 per share), subject to adjustment and contingent upon and only under the following 
circumstances: (1) if the closing price of the Company’s common stock reaches specified thresholds or the trading 
price of the notes falls below specified thresholds, (2) if the notes are called for redemption, (3) if specified 
distributions to holders of the Company’s common stock are made or specified corporate transactions occur, (4) if 
a fundamental change occurs, or (5) during the ten trading days prior to but excluding the maturity date.  As of 
December 31, 2009, the notes and underlying shares had been registered under a shelf registration statement.  
Subsequent to year end the Company deregistered the shelf registration statement for the 3.50% Senior 
Convertible Notes.  If the Company becomes involved in a material transaction or corporate development, it may 
suspend trading of the 3.50% Senior Convertible Notes under the prospectus.  In the event the suspension period 
exceeds 45 days within any three-month period or 90 days within any twelve-month period, the Company will be 
required to pay additional interest to all holders of the 3.50% Senior Convertible Notes, not to exceed a rate per 
annum of 0.50 percent of the issue price of the 3.50% Senior Convertible Notes; provided that no such additional 
interest shall accrue after April 4, 2009. 

Upon conversion of the 3.50% Senior Convertible Notes, holders will receive cash or common stock or 

any combination thereof as elected by the Company.  At any time prior to the maturity date of the notes, the 
Company has the option to unilaterally and irrevocably elect to net share settle its obligations upon conversion of 
the notes in cash and, if applicable, shares of common stock.  If the Company makes this election, then the 
Company will pay the following to holders for each $1,000 principal amount of notes converted in lieu of shares 
of common stock: (1) an amount in cash equal to the lesser of (i) $1,000 or (ii) the conversion value determined in 
the manner set forth in the indenture for the 3.50% Senior Convertible Notes, and (2) if the conversion value 
exceeds $1,000, the Company will also deliver, at its election, cash or common stock or a combination of cash 
and common stock with respect to the remaining value deliverable upon conversion.  Currently, it is the 
Company’s intention to net share settle the 3.50% Senior Convertible Notes.  However, the Company has not 
made this a formal legal irrevocable election and thereby reserves the right to settle the 3.50% Senior Convertible 
Notes in any manner allowed under the indenture as business conditions warrant. 

If the holder elects to convert its notes in connection with certain events that constitute a change of 
control before April 1, 2012, the Company will pay, to the extent described in the related indenture, a make-whole 
premium by increasing the conversion rate applicable to the 3.50% Senior Convertible Notes.  In addition, the 
Company will pay contingent interest in cash, commencing with any six-month period beginning on or after 
April 1, 2012, if the average trading price of a note for the five trading days ending on the third trading day 
immediately preceding the first day of the relevant six-month period equals 120 percent or more of the principal 
amount of the 3.50% Senior Convertible Notes. 

F-22 

 
On or after April 6, 2012, the Company may redeem for cash all or a portion of the 3.50% Senior 
Convertible Notes at a redemption price equal to 100 percent of the principal amount of the notes to be redeemed 
plus accrued and unpaid interest, if any, up to but excluding the applicable redemption date.  Holders of the 3.50% 
Senior Convertible Notes may require the Company to purchase all or a portion of their notes on each of 
April 1, 2012, April 1, 2017, and April 1, 2022, at a purchase price equal to 100 percent of the principal amount 
of the notes to be repurchased plus accrued and unpaid interest, if any, up to but excluding the applicable purchase 
date.  On April 1, 2012, the Company may pay the purchase price in cash, in shares of common stock, or in any 
combination of cash and common stock.  On April 1, 2017, and April 1, 2022, the Company must pay the 
purchase price in cash.   

New authoritative accounting guidance under FASB ASC Topic 470 

Effective January 1, 2009, the new authoritative accounting guidance under ASC Topic 470 required 

issuers of convertible debt that may be settled fully or partially in cash upon conversion to account separately for 
the liability and equity components of the debt in a manner that reflects the entity’s nonconvertible debt 
borrowing rate when interest cost is recognized in subsequent periods.  ASC Topic 470 applies to the Company’s 
3.50% Senior Convertible Notes.  Under the adoption provisions of ASC Topic 470, the Company retrospectively 
applied its provisions and restated the Company’s consolidated financial statements for prior periods. 

Under the provisions of ASC Topic 470, $42.0 million of the carrying value of the 3.50% Senior 
Convertible Notes was recorded as additional paid-in capital as of the April 4, 2007, issuance date.  This amount 
represents the equity component of the proceeds from the 3.50% Senior Convertible Notes, calculated assuming a 
7.0% discount rate, which is the estimate of what the Company’s borrowing rate for a similar debt instrument 
without the conversion feature would have been at the date of the issuance of the 3.50% Senior Convertible 
Notes.  Upon retrospective application, the adoption resulted in a $6.8 million decrease in the Company’s retained 
earnings at December 31, 2008, which was comprised of non-cash interest expense of $10.8 million, net of 
capitalized interest of $2.2 million, less deferred taxes of $4.0 million, for the period from April 4, 2007, through 
December 31, 2008.  The following table presents the December 31, 2008, consolidated balance sheet line items

Weighted-Average Interest Rate Paid and Capitalized Interest 

The weighted-average interest rate paid in 2009, 2008, and 2007, was 5.4 percent, 5.8 percent, and 

6.7 percent, respectively, including commitment fees paid on the unused portion of the credit facility aggregate 
commitment, amortization of deferred financing costs, amortization of debt discount, amortization of the 
contingent interest embedded derivative associated with the 5.75% Senior Convertible Notes for 2007, and the 
effect of interest rate swaps.  The average outstanding loan balance in 2009 increased in comparison to the 
average outstanding loan balance in 2008, while the rates associated with the balances decreased.  The decrease is 
attributed to significantly lower LIBOR and Prime rates in 2009 compared to 2008.  Capitalized interest costs for 
the Company for the years ended December 31, 2009, 2008, and 2007, were $1.9 million, $4.7 million, and 
$6.7 million, respectively.

The Company leases office space under various operating leases with terms extending as far as 
May 31, 2022.  Rent expense, net of sublease income, was $2.3 million, $2.4 million, and $1.9 million in 2009, 
2008, and 2007, respectively. The Company also leases office equipment under various operating leases.  As of 
December 31, 2009, the Company has a sublease through May 2012 with payments due to St. Mary of $185,000 
per year through 2011 and $62,000 in 2012.  This sublease was terminated on January 15, 2010. 

The Company is subject to litigation and claims that have arisen in the ordinary course of business. The 

Company accrues for such items when a liability is both probable and the amount can be reasonably estimated.  In 
the opinion of management, the results of such pending litigation and claims will not have a material effect on the 
results of operations, the financial position, or cash flows of the Company. 

Note 7 – Compensation Plans 

Cash Bonus Plan 

The Company has a cash bonus plan based on a performance measurement framework whereby selected 

eligible employee participants may be awarded an annual cash bonus.  The plan document provides that no 
participant may receive an annual bonus under the plan of more than 200 percent of his or her base salary.  As the 
plan is currently administered, any awards under the plan are based on Company and regional performance, and 
are then further refined by individual performance.  The Company accrues cash bonus expense based upon the 
Company’s current year’s performance.  Included in general and administrative and exploration expense in the 
accompanying consolidated statements of operations are $7.8 million, $6.4 million, and $3.6 million of cash 
bonus expense related to the specific performance year for the years ended December 31, 2009, 2008, and 2007, 
respectively. 

Equity Incentive Compensation Plan 

There are several components to the equity compensation plan that are described in this section.  Various 

types of equity awards have been granted by the Company in different periods.  These disclosures reflect the 
disclosure requirements for all equity awards still outstanding. 

In May 2006 the stockholders approved the 2006 Equity Incentive Compensation Plan, which was 

subsequently renamed the Equity Incentive Compensation Plan (the “Equity Plan”), to authorize the issuance of 
restricted stock, RSUs, non-qualified stock options, incentive stock options, stock appreciation rights, and stock-
based awards to key employees, consultants, and members of the Board of Directors of St. Mary or any affiliate 
of St. Mary.  The Equity Plan serves as the successor to the St. Mary Land & Exploration Company Stock Option 
Plan, the St. Mary Land & Exploration Company Incentive Stock Option Plan, the St. Mary Land & Exploration 

F-25 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Company Restricted Stock Plan, and the St. Mary Land & Exploration Company Non-Employee Director Stock 
Compensation Plan (collectively referred to as the “Predecessor Plans”).  All grants of equity are now made 
pursuant to the Equity Plan, and no further grants will be made under the Predecessor Plans.  Each outstanding 
award under the Predecessor Plans prior to the effective date of the Equity Plan continues to be governed solely 
by the terms and conditions of the instruments evidencing such grants or issuances.  An amendment and 
restatement of the Equity Plan was approved by the Company’s stockholders at the 2008 annual stockholders’ 
meeting held on May 21, 2008.  The Equity Plan was further amended at the 2009 annual stockholders’ meeting 
held on May 20, 2009. 

As of December 31, 2009, 1.8 million shares of common stock remained available for grant under the 

Equity Plan.  The issuance of a direct share benefit such as an outright grant of common stock, a grant of a 
restricted share, a RSU grant, or a PSA grant, counts as 1.43 shares against the number of shares available to be 
granted under the Equity Plan.  At the end of a three-year performance period a final multiplier ranging between 
zero and two is applied to each PSA so that each performance share granted has the potential to result in the 
issuance of two shares of common stock.  Consequently, each performance share granted counts as 2.86 shares 
against the number of shares available to be granted under the Equity Plan.  Stock option grants count as one 
share for each instrument granted against the number of shares available to be granted under the Equity Plan.  The 
Company has outstanding stock option awards under the Predecessor Plans. 

Performance Share Awards Under the Equity Incentive Compensation Plan 

In 2007, PSAs became the primary form of long-term equity incentive compensation replacing standalone 
RSU grants and awards of interest in pools under the Net Profits Plan.  PSAs represent the right to receive a share 
of the Company’s common stock which can be multiplied by a factor ranging from zero to two times the number 
of PSAs granted on the award date depending on the Company’s performance after completion of a three-year 
performance period.  The performance criteria for the PSAs are based on a combination of the Company’s 
cumulative TSR for the performance period and the relative measure of the Company’s TSR compared with the 
cumulative TSR of an index comprised of certain peer companies for the performance period. 

On August 1, 2009, the Company granted 725,092 PSAs with a performance period ending 
June 30, 2012.  The PSAs will vest 1/7th on August 1, 2010, 2/7ths on August 1, 2011, and 4/7ths on 
August 1, 2012.  The fair value of the Company’s PSAs granted on August 1, 2009, was $25.8 million and is 
being recognized as general and administrative and exploration expense over the vesting period of the award. 

On August 1, 2008, the Company granted 465,751 PSAs with a performance period ending 
June 30, 2011.  The PSAs will vest 1/7th on August 1, 2009, 2/7ths on August 1, 2010, and 4/7ths on 
August 1, 2011.  The fair value of the Company’s PSAs granted on August 1, 2008, was $12.3 million and is 
being recognized as general and administrative and exploration expense over the vesting period of the award. 

In measuring compensation expense related to the grant of PSAs, the Company estimates the fair value of 

the award on the grant date.  The fair value of PSAs is measured by a stochastic process method using the 
Geometric Brownian Motion Model (“GBM Model”).  A stochastic process is a mathematically defined equation 
that can create a series of outcomes over time.  These outcomes are not deterministic in nature, which means that 
by iterating the equations multiple times, different results will be obtained for those iterations.  In the case of the 
Company’s PSAs, the Company cannot predict with certainty the path its stock price or the stock prices of its 
peers will take over the three-year performance period.  By using a stochastic simulation the Company can create 
multiple prospective stock pathways, statistically analyze these simulations, and ultimately make inferences to the 
most likely path the stock price will take.  As such, because future stock prices are stochastic, or probabilistic with 
some direction in nature, the stochastic method, specifically the GBM Model is deemed an appropriate method by 
which to determine the fair value of the PSAs.

vested may vary depending on the ending three-year multiplier, which ranges from zero to two. 

The total fair value of PSAs that vested during the year ended December 31, 2009, was $1.8 million.   

General and administrative and exploration expense recorded for PSAs was $9.3 million and $2.5 million for the 
years ended December 31, 2009, and 2008, respectively.  As of December 31, 2009, there was $25.0 million of 
total unrecognized expense related to PSAs, which is being amortized through 2012. 

Restricted Stock Incentive Program Under the Equity Incentive Compensation Plan 

The Company historically had a long-term incentive program whereby grants of restricted stock or RSUs 

were awarded to eligible employees, consultants, and members of the Board of Directors.  Restrictions and 
vesting periods for the awards were determined at the discretion of the Board of Directors and were set forth in 
the award agreements.  Each RSU represents a right for one share of the Company’s common stock to be 
delivered upon settlement of the award at the end of a specified period.  These grants were determined annually 
based on the same Company performance formula used to determine the annual cash bonus.  RSUs were also 
issued in 2008 as the Company transitioned to using PSAs as the primary long-term equity incentive 
compensation awards and again in 2009 as a component of the Company’s long-term equity incentive 
compensation program. 

The Company issued 241,745 RSUs on August 1, 2009, with a weighted-average grant-date fair value of 
$23.87 with a total fair value of $5.8 million.  These RSUs vest 1/7th on August 1, 2010, 2/7ths on August 1, 2011, 
and 4/7ths on August 1, 2012 and is being recognized as general and administrative and exploration expense over 
the vesting period of the award. 

St. Mary issued 265,373 RSUs on June 30, 2008, as a transitional award to employees when the Company 

moved from the legacy equity incentive compensation plan to the new PSA program.  The total fair value 
associated with this issuance was $17.2 million as measured on the grant date.  The granted RSUs vest one third 
on each date of December 15th 2008, 2009, and 2010.  General and administrative and exploration expense is 
recorded over the vesting period of the award. 

The Company issued 158,744 RSUs on February 28, 2008, related to 2007 performance, and 78,657 

RSUs on February 28, 2007, related to 2006 performance.  The total fair value associated with these issuances 
was $6.0 million for the 2008 grant and $2.5 million for the 2007 issuance as measured on the respective grant 
dates.  These granted RSUs vested 25 percent immediately upon grant and 25 percent on each of the first three 
anniversary dates of the grant.  The fair values of these awards are being recognized as general and administrative 
and exploration expense over the vesting period of the awards. 

The Company issued an additional 4,290 and 23,977 RSUs to certain employees during 2008 and 2007, 

respectively.  The total fair value associated with the 2008 and 2007 issuances was $164,000 and $803,000, 
respectively, as measured on the respective grant dates.  These grants have various vesting schedules.

For RSUs awarded prior to 2006, vested shares of common stock underlying the RSU grants were issued 

on the third anniversary of the grant, at which time the shares carried no further restrictions.  On December 31, 
2007 the Company eliminated the restriction period that extends beyond the vesting period so shares are now 
issued without restriction upon vesting, rather than on the third anniversary of the award for all awards granted 
after 2005.  Therefore the fair value of a RSU award granted after December 31, 2007, is equal to the market 
value of the underlying stock on the date of the grant.  This change fell within the safe harbor adoption provisions 
of the U.S. Treasury regulations interpreting IRC provisions governing deferred compensation.  A mutual election 
of the employee and the Company was required to effect this change for each outstanding award.  The majority of 
the awards were modified by mutual election, and as such, the incremental value associated with removal of this 
restriction period was $556,000 and is being amortized over the remaining respective service periods for these 
awards. 

For grants made beginning with the 2006 grant period, the Company is using the accelerated amortization 

method whereby approximately 48 percent of the total estimated compensation expense is recognized in the first 
year of the vesting period.  As of December 31, 2009, a total of 408,356 RSUs were outstanding, of which 1,233 
were vested.  The total general and administrative and exploration expense associated with RSUs for the years 
ended December 31, 2009, 2008, and 2007, was $7.9 million, $11.0 million, and $8.4 million, respectively.  As of 
December 31, 2009, there was $10.0 million of total unrecognized expense related to unvested RSU awards and is 
being amortized through 2012. 

During 2009, 2008, and 2007, the Company converted 215,700, 678,197, and 427,059 RSUs, 
respectively.  The Company and the majority of grant participants mutually agreed to net share settle the awards 
to cover income and payroll tax withholdings as provided for in the plan document and award agreements.  As a 
result, the Company issued net shares of common stock of 156,252; 482,602; and 302,370 for 2009, 2008, and 
2007, respectively.  The remaining 59,448, 195,595, and 124,689 shares were withheld to satisfy income and 
payroll tax withholding obligations that occurred upon the delivery of the shares underlying those RSUs for 2009, 
2008, and 2007, respectively. 

In accordance with ASC Topic 718, when measuring compensation expense related to the grant of RSUs 

the Company estimates the fair value of the award on the grant date.  For grants prior to January 1, 2008, the 
Company had a restriction period beyond vesting.  Therefore, the fair value of the RSUs was inherently less than 
the market value of an unrestricted share of St. Mary’s common stock.  The fair value of RSUs with restriction 
periods beyond the vesting dates were measured using the Black-Sholes option-pricing model.  The Company’s 
computation of expected volatility was based on the historic volatility of St. Mary’s common stock.  The 
Company’s computation of expected life was determined based on historical experience of similar awards, giving 
consideration to the contractual terms of the awards, vesting schedules, and expectations of future employee 
behavior.  The interest rate for periods within the contractual life of the award was based on the U.S. Treasury 
constant maturity yield at the time of the grant. 

The fair values of RSU awards granted prior to January 1, 2008, were estimated using the following 

weighted-average assumptions: 

Risk free interest rate 
Dividend yield 
Volatility factor of the expected market 

price of the Company’s common stock

Stock Awards Under the Equity Incentive Compensation Plan 

As part of hiring a new senior executive in the second quarter of 2006, St. Mary granted a special 

common stock award of 20,000 shares that vested immediately upon commencement of employment.  The fair 
value associated with this award was $727,600.  In addition to this award, the employee will earn an additional 
5,000 shares over a four-year period and an additional 15,000 shares contingent on the Company meeting certain 
net asset growth performance conditions over a four-year period.  In 2009, 2008, and 2007, the Company issued 
1,250, 3,750, and 1,250 worth of guaranteed and contingent shares with associated fair values of $45,000, 
$142,000, and $45,000, respectively.  The fair value of these awards is being recorded as compensation expense 
over the vesting period. 

As part of hiring a new senior executive in the third quarter of 2008, St. Mary granted a special restricted 

stock award of 15,496 shares that vested one half on December 15, 2009, and the other half will vest on 
December 15, 2010.  The fair value of this award was $600,005 and is being recorded as compensation expense 
over the vesting period.  For the years ended December 31, 2009, and 2008, the Company recorded general and 
administrative and exploration expense of $358,000 and $115,000, respectively, related to this award. 

A summary of the status and activity of non-vested stock awards and RSUs for the years ending

$4.9 million, $9.4 million, and $9.8 million, respectively. 

ASC Topic 718 requires cash flows resulting from excess tax benefits to be classified as part of cash 

flows from financing activities.  Excess tax benefits are realized tax benefits from tax deductions for vested RSUs 
and exercised options in excess of the deferred tax asset attributable to stock compensation costs for such RSUs 
and options.  The Company has recorded $13.9 million and $9.9 million of excess tax benefits for the years ended 
December 31, 2008, and 2007, respectively, as cash inflows from financing activities.  The Company recorded no 
excess tax benefits for the year ended December 31, 2009.  Cash received from exercises under all share-based 
payment arrangements for the years ended December 31, 2009, 2008, and 2007, was $1.6 million, $10.8 million, 
and $9.1 million, respectively.

Stock Option Grants Under the Equity Incentive Compensation Plan 

The Company has previously granted stock options under the St. Mary Land & Exploration Company 

Stock Option Plan and the St. Mary Land & Exploration Company Incentive Stock Option Plan.  The last 
issuance of stock options was December 31, 2004.  Stock options to purchase shares of the Company’s common 
stock had been granted to eligible employees and members of the Board of Directors.  All options granted to date 
under the option plans have been granted at exercise prices equal to the respective closing market price of the 
Company’s underlying common stock on the grant dates.  All stock options granted under the option plans are 
exercisable for a period of up to ten years from the date of grant. 

During the years ended December 31, 2008, and 2007, the Company recognized general and 

administrative and exploration expense of $17,000 and $437,000, respectively, related to stock options that were 
outstanding and unvested upon adoption of ASC Topic 718 on January 1, 2006.  There was no expense associated 
with stock options or unvested stock options outstanding for the year ended December 31, 2009.

Director Shares 

In 2009, 2008, and 2007, the Company issued 50,094, 23,113, and 32,504 shares, respectively, of 
restricted common stock from treasury to its non-employee directors pursuant to the Company’s Equity Plan.  The 
Company recorded general and administrative and exploration expense related to the issuances of shares to non-
employee directors of $688,000, $1.0 million, and $984,000 for the years ended December 31, 2009, 2008, and 
2007, respectively. 

Employee Stock Purchase Plan 

Under the St. Mary Land & Exploration Company Employee Stock Purchase Plan (“the ESPP”), eligible 
employees may purchase shares of the Company’s common stock through payroll deductions of up to 15 percent 
of eligible compensation.  The purchase price of the stock is 85 percent of the lower of the fair market value of the 
stock on the first or last day of the six-month offering period, and shares issued under the ESPP through 
December 31, 2009, are restricted for a period of 18 months from the date issued.  Effective January 1, 2010, 
shares issued under the ESPP will be restricted for a six month period from the date issued.  The ESPP is intended 
to qualify under Section 423 of the IRC.  The Company has set aside 2,000,000 shares of its common stock to be 
available for issuance under the ESPP, of which 1,468,275 shares are available for issuance as of December 31, 
2009.  Shares issued under the ESPP totaled 86,308 in 2009, 45,228 in 2008, and 29,534 in 2007.  Total proceeds 
to the Company for the issuance of these shares was $1.5 million in 2009, $1.1 million in 2008, and $919,000 in 
2007.

2008, and 2007, respectively, based on the estimated fair value of grants on the respective grant dates. 

401(k) Plan 

The Company has a defined contribution pension plan (the “401(k) Plan”) that is subject to the Employee 

Retirement Income Security Act of 1974.  The 401(k) Plan allows eligible employees to contribute up to 60 
percent of their base salaries.  The Company matches each employee’s contribution up to six percent of the 
employee’s base salary and may make additional contributions at its discretion.  The Company’s contributions to 
the 401(k) Plan were $2.5 million, $2.0 million, and $1.5 million for the years ended December 31, 2009, 2008, 
and 2007, respectively.  No discretionary contributions were made by the Company to the 401(k) Plan for any of 
these years. 

Net Profits Plan 

Under the Company’s Net Profits Plan, all oil and gas wells that were completed or acquired during a 

year were designated within a specific pool.  Key employees recommended by senior management and designated 
as participants by the Company’s Compensation Committee of the Board of Directors and employed by the 
Company on the last day of that year became entitled to payments under the Net Profits Plan after the Company 
has received net cash flows returning 100 percent of all costs associated with that pool.  Thereafter, ten percent of 
future net cash flows generated by the pool are allocated among the participants and distributed at least annually.  
The portion of net cash flows from the pool to be allocated among the participants increases to 20 percent after the 
Company has recovered 200 percent of the total costs for the pool, including payments made under the Net Profits 
Plan at the ten percent level.  In December 2007 the Board discontinued the creation of new pools under the Net 
Profits Plan.  Consequently, the 2007 Net Profits Plan pool was the last pool established by the Company.  All 
pools are fully vested as of December 31, 2009. 

Cash payments made under the Net Profits Plan that have been recorded as either general and 

administrative expense or exploration expense are detailed in the table below:

Additionally, the Company made cash payments under the Net Profits Plan of $724,000 for the year ended 

December 31, 2009, as a result of sales proceeds from properties sold during the fourth quarter of 2009.  For the year 
ended December 31, 2008, the Company made cash payments under the Net Profits Plan of $15.1 million as a result 
of sales proceeds from the Abraxas and Greater Green River Basin divestitures.  The cash payments are accounted 
for as a reduction in the gain (loss) on divestiture activity in the accompanying consolidated statements of 
operations.  There were no significant cash payments made under the Net Profits Plan as the result of property 
divestitures during 2007. 

The Company records changes in the present value of estimated future payments under the Net Profits Plan 

as a separate line item in the accompanying consolidated statements of operations.  The change in the estimated 
liability is recorded as a non-cash expense or benefit in the current period.  The amount recorded as an expense or 
benefit associated with the change in the estimated liability is not allocated to general and administrative expense or 
exploration expense because it is associated with the future net cash flows from oil and gas properties in the 
respective pools rather than results being realized through current period production.  The table below presents the 
estimated allocation of the change in the liability if the Company did allocate the adjustment to these specific 
functional line items based on the current allocation of actual distributions made by the Company.  As time 
progresses, less of the distributions relate to prospective exploration efforts as more of the distributions are made to 
employees that have terminated employment and do not provide ongoing exploration support to the Company.

Effective January 1, 2009, new authoritative accounting guidance under FASB ASC Topic 715, 
“Compensation – Retirement Benefits” (“ASC Topic 715”) amends the disclosure requirements of plan assets for 
defined benefit pensions and other postretirement plans.  The objective of ASC Topic 715 is to provide users of 
financial statements with an understanding of how investment allocation decisions are made, the major categories 
of plan assets held by the plans, the inputs and valuation techniques used to measure the fair value of plan assets, 
significant concentration of risk within a company’s plan assets, fair value measurements determined using 
significant unobservable inputs, and a reconciliation of changes between the beginning and ending balances for all 
level 3 inputs. 

Pension Plans 

The Company has a non-contributory defined benefit pension plan covering substantially all employees 
who meet age and service requirements (the “Qualified Pension Plan”).  The Company also has a supplemental 
non-contributory pension plan covering certain management employees (the “Nonqualified Pension Plan”). 

The Company recognizes the funded status (i.e., the difference between the fair value of plan assets and 

the projected benefit obligation) of the Company’s pension plan in the consolidated balance sheets as either an 
asset or a liability and recognizes a corresponding adjustment to accumulated other comprehensive income, net of 
tax.  The projected benefit obligation is the actuarial present value of the benefits earned to date by plan 
participants based on employee service and compensation including the effect of assumed future salary increases.  
The accumulated benefit obligation uses the same factors as the projected benefit obligation but excludes the 

F-33 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
   
 
 
effects of assumed future salary increases.  The Company’s measurement date for plan assets and obligations is 
December 31.

The Company’s underfunded status for the Pension Plans for the years ended December 31, 2009, and 

2008, is $9.4 million and $8.2 million, respectively, and is recognized in the accompanying consolidated balance 
sheets as a portion of other noncurrent liabilities.  No plan assets of the Qualified Pension Plan are expected to be 
returned to the Company during the fiscal year ended December 31, 2009.  There are no plan assets in the 
Nonqualified Pension Plan.

Pension expense is determined based upon the annual service cost of benefits (the actuarial cost of 

benefits earned during a period) and the interest cost on those liabilities, less the expected return on plan assets.  
The expected long-term rate on plan assets is applied to a calculated value of plan assets that recognizes changes 
in fair value over a five-year period.  This practice is intended to reduce year-to-year volatility in pension expense, 
but it can have the effect of delaying recognition of differences between actual returns on assets and expected 
returns based on long-term rate of return assumptions.  Amortization of unrecognized net gain or loss resulting 
from experience different from that assumed and from changes in assumptions (excluding asset gains and losses 
not yet reflected in market-related value) is included as a component of net periodic benefit cost for a year.  If, as 
of the beginning of the year, that unrecognized net gain or loss exceeds 10 percent of the greater of the projected

Prior service costs are amortized on a straight-line basis over the average remaining service period of 

active participants.  Gains and losses in excess of ten percent of the greater of the benefit obligation and the 
market-related value of assets are amortized over the average remaining service period of active participants.

The Company’s pension investment policy includes various guidelines and procedures designed to ensure 
that assets are prudently invested in a manner necessary to meet the future benefit obligation of the Pension Plans.  
The policy does not permit the direct investment of plan assets in the Company’s securities.  The Company’s 
investment horizon is long-term and accordingly the target asset allocations encompass a strategic, long-term 
perspective of capital markets, expected risk and return behavior and perceived future economic conditions.  The 
key investment principles of diversification, assessment of risk, and targeting the optimal expected returns for 
given levels of risk are applied. 

The Company’s investment portfolio contains a diversified blend of common stocks and bonds, which 

may reflect varying rates of return.  The investments are further diversified within each asset classification.  The 
portfolio diversification provides protection against a single security or class of securities having a 
disproportionate impact on aggregate investment performance.  The actual asset allocations are reviewed and 
rebalanced on a periodic basis to maintain the target allocations.  The Company’s weighted-average asset 
allocation for the Qualified Pension Plan is as follows:

There is no asset allocation of the Nonqualified Pension Plan since there are no plan assets in that plan.  

An expected return on plan assets of 7.5 percent was used to calculate the Company’s obligation under the 
Qualified Pension Plan for 2009 and 2008.  Factors considered in determining the expected return include the 60 
percent equity and 40 percent debt securities mix of investment of plan assets and the long-term historical rate of 
return provided by the equity and debt securities markets.  The difference in investment income using the 
projected rate of return compared to the actual rates of return for the past two years was not material and will not 
have a material effect on the statements of operations or cash flows from operating activities in future years.

Note 9 – Asset Retirement Obligations 

The Company recognizes an estimated liability for future costs associated with the abandonment of its oil 
and gas properties.  A liability for the fair value of an asset retirement obligation and a corresponding increase to

the carrying value of the related long-lived asset are recorded at the time a well is completed or acquired.  The 
increase in carrying value is included in proved oil and gas properties in the accompanying consolidated balance 
sheets.  The Company depletes the amount added to proved oil and gas property costs and recognizes expense in 
connection with the accretion of the discounted liability over the remaining estimated economic lives of the 
respective oil and gas properties.  Cash paid to settle asset retirement obligations is included in the operating 
section of the Company’s accompanying consolidated statements of cash flows. 

The Company’s estimated asset retirement obligation liability is based on historical experience in 

abandoning wells, estimated economic lives, estimates as to the cost to abandon the wells in the future, and 
federal and state regulatory requirements.  The liability is discounted using the credit-adjusted risk-free rate 
estimated at the time the liability is incurred or revised.  The credit-adjusted risk-free rates used to discount the 
Company’s abandonment liabilities range from 6.5 percent to 12.0 percent.  Revisions to the liability could occur 
due to changes in estimated abandonment costs or well economic lives, or if federal or state regulators enact new 
requirements regarding the abandonment of wells. 

A reconciliation of the Company’s asset retirement obligation liability is as follows:

platforms that are being relinquished or plugged.  Accounts payable and accrued expenses contained $7.3 million 
related to the Company’s asset retirement obligation as of December 31, 2008.  The amount relates to the 
estimated plugging and abandonment costs associated with one offshore platform that was destroyed during 
Hurricane Ike.  Please refer to Note 13 – Hurricanes for additional details. 

Note 10 – Derivative Financial Instruments 

New Authoritative Accounting Guidance under FASB ASC Topic 815 

Effective January 1, 2009, new authoritative accounting guidance under FASB ASC Topic 815, 
“Derivatives and Hedging” (“ASC Topic 815”) requires entities to provide greater transparency about how and 
why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for, 
and how derivative instruments and related hedged items affect an entity’s financial position, results of 
operations, and cash flows. 

Oil, Natural Gas and NGL Commodity Hedges 

To mitigate a portion of the potential exposure to adverse market changes in oil and gas prices and the 
associated impact on cash flows, the Company has entered into various derivative contracts.  The Company’s 
derivative contracts in place include swap and collar arrangements for oil, natural gas, and natural gas liquids 
(“NGLs”).  As of December 31, 2009, the Company has hedge contracts in place through the end of 2012 for a 
total of approximately 6 million Bbls of anticipated crude oil production, 63 million MMBtu of anticipated natural 
gas production, and 1 million Bbls of anticipated natural gas liquids production.

The Company attempts to qualify its oil, gas and NGL derivative instruments as cash flow hedges for 
accounting purposes under ASC Topic 815.  The Company formally documents all relationships between the 
derivative instruments and the hedged production, as well as the Company’s risk management objective and 
strategy for the particular derivative contracts.  This process includes linking all derivatives that are designated as 
cash flow hedges to the specific forecasted sale of oil, gas or NGL at its physical location.  The Company also 
formally assesses (both at the derivative’s inception and on an ongoing basis) whether the derivatives being 
utilized have been highly effective in offsetting changes in the cash flows of hedged production and whether those 
derivatives may be expected to remain highly effective in future periods.  If it is determined that a derivative has 
ceased to be highly effective as a hedge, the Company will discontinue hedge accounting for that derivative 
prospectively.  If hedge accounting is discontinued and the derivative remains outstanding, the Company will 
recognize all subsequent changes in its fair value in the Company’s consolidated statements of operations for the 
period in which the change occurs.  As of December 31, 2009, all oil, natural gas, and NGL derivative 
instruments qualified as cash flow hedges for accounting purposes.  The Company anticipates that all forecasted 
transactions will occur by the end of their originally specified periods.  All contracts are entered into for other 
than trading purposes. 

The Company’s oil, gas and NGL hedges are measured at fair value and are included in the 
accompanying consolidated balance sheets as derivative assets and liabilities.  The Company derives internal 
valuation estimates taking into consideration the counterparties’ credit worthiness, the Company’s credit 
worthiness, and the time value of money.  Those internal valuations are then compared to the counterparties’ 
mark-to-market statements.  The consideration of the factors results in an estimated exit-price for each derivative 
asset or liability under a market place participant’s view.  Management believes that this approach provides a 
reasonable, non-biased, verifiable, and consistent methodology for valuing derivative instruments.  The derivative 
instruments utilized by the Company are not considered by management to be complex, structured, or illiquid.  
The oil, gas and NGL derivative markets are highly active.  The fair value of oil, gas and NGL derivative 
contracts designated and qualifying as cash flow hedges under ASC Topic 815 was a net liability of $80.9 million 
and a net asset of $105.3 million at December 31, 2009, and 2008, respectively.

After-tax changes in the fair value of derivative instruments designated as cash flow hedges, to the extent 

they are effective in offsetting cash flows attributed to the hedged risk, are recorded in accumulated other 
comprehensive income in the accompanying consolidated balance sheets until the hedged item is realized in 
earnings upon the sale of the associated hedged production.  As of December 31, 2009, the amount of unrealized 
loss net of deferred income taxes to be reclassified from accumulated other comprehensive income to realized oil 
and gas hedge gain (loss) in the Company’s accompanying consolidated statements of operations in the next 
twelve months is $6.5 million. 

The Company seeks to minimize ineffectiveness by entering into oil derivative contracts indexed to the 

New York Mercantile Exchange West Texas Intermediate (“NYMEX WTI”) index and natural gas derivative 
contracts indexed to regional index prices associated with pipelines in proximity to the Company’s areas of 
production.  As the Company’s derivative contracts contain the same index as the Company’s sales contracts, this 
results in derivative contracts that are highly correlated with the underlying hedged item.

Interest Rate Derivative Contracts 

In September 2007, the Company entered into a one-year floating-to-fixed interest rate derivative contract 

for a notional amount of $75 million.  Under the agreement, the Company paid a fixed rate of 4.90 percent and 
received a variable rate based on the one-month LIBOR rates.  The interest rate derivative contract was measured 
at fair value using quoted prices in active markets.  The interest rate swap was a straightforward, non-complex, 
non-structured instrument that was highly liquid.  A mark-to-market valuation took into consideration anticipated 
cash flows from the transaction using quoted market prices, other economic data and assumptions, and pricing 
indications used by other market participants was used to value the swap.  Given the degree of varying 
assumptions used to value the swap, it was deemed as having Level 2 inputs.  This derivative qualified for cash 
flow hedge treatment under ASC Topic 815.  The Company recorded a net derivative loss of $1.0 million in the 
accompanying consolidated statements of operations for the year ended December 31, 2008, related to this 
interest rate derivative contract.  This contract was settled in the third quarter of 2008. 

Convertible Note Derivative Instrument 

The contingent interest provision of the 3.50% Senior Convertible Notes is a derivative instrument.  As of 

December 31, 2009 and 2008, the value of this derivative was determined to be immaterial. 

Note 11 – Fair Value Measurements 

On January 1, 2008, the Company applied new authoritative accounting guidance under FASB ASC 

Topic 820, “Fair Value Measurements and Disclosures” (“ASC Topic 820”) for all financial assets and liabilities 
measured at fair value on a recurring basis.  The topic established a framework for measuring fair value and 
required enhanced disclosures about fair value measurements.  ASC Topic 820 defined fair value as the price that 
would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between 
market participants at the measurement date.  The topic established market or observable inputs as the preferred 
sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs.  
The topic established a hierarchy for grouping these assets and liabilities based on the significance level of the 
following inputs: 

  Level 1 – Quoted prices in active markets for identical assets or liabilities 

  Level 2 – Quoted prices in active markets for similar assets and liabilities, quoted prices for identical 
or similar instruments in markets that are not active, and model-derived valuations whose inputs are 
observable or whose significant value drivers are observable 

  Level 3 – Significant inputs to the valuation model are unobservable 

On January 1, 2009, the Company applied ASC Topic 820 to all non-financial assets and liabilities 

measured at fair value on a nonrecurring basis, including long-lived assets and assets held for sale measured at 
fair value under ASC Topic 360 and asset retirement obligations initially measured at fair value under FASB ASC 
Topic 410, “Asset Retirement and Environmental Obligations” (“ASC Topic 410”).  The adoption of ASC Topic 
820 for non-financial assets and liabilities did not have a material impact on the Company’s financial statements.

Both financial and non-financial assets and liabilities are categorized within the hierarchy based on the 

lowest level of input that is significant to the fair value measurement.  The following is a description of the 
valuation methodologies used by the Company as well as the general classification of such instruments pursuant 
to the hierarchy. 

Derivatives 

The Company uses Level 2 inputs to measure the fair value of oil and gas hedges.  Fair values are based 

upon interpolated data.  The Company derives internal valuation estimates taking into consideration the 
counterparties’ credit ratings, the Company’s credit rating, and the time value of money.  These valuations are 
then compared to the respective counterparties’ mark-to-market statements.  The considered factors result in an 
estimated exit-price that management believes provides a reasonable and consistent methodology for valuing 
derivative instruments. 

Generally, market quotes assume that all counterparties have near zero, or low, default rates and have 

equal credit quality.  However, an adjustment may be necessary to reflect the credit quality of a specific 
counterparty to determine the fair value of the instrument.  The Company monitors the credit ratings of its 
counterparties and may ask counterparties to post collateral if their ratings deteriorate.  In some instances the 
Company will attempt to novate the trade to a more stable counterparty. 

Valuation adjustments are necessary to reflect the effect of the Company’s credit quality on the fair value 
of any liability position with a counterparty.  This adjustment takes into account any credit enhancements, such as 
collateral margin that the Company may have posted with a counterparty, as well as any letters of credit between 
the parties.  The methodology to determine this adjustment is consistent with how the Company evaluates 
counterparty credit risk, taking into account the Company’s credit rating, current credit facility margins, and any

change in such margins since the last measurement date.  The majority of the Company’s derivative 
counterparties are members of St. Mary’s credit facility bank syndicate. 

The methods described above may result in a fair value estimate that may not be indicative of net 
realizable value or may not be reflective of future fair values and cash flows.  While the Company believes that 
the valuation methods utilized are appropriate and consistent with the requirements of ASC Topic 820 and with 
other marketplace participants, the Company recognizes that third parties may use different methodologies or 
assumptions to determine the fair value of certain financial instruments that could result in a different estimate of 
fair value at the reporting date. 

Net Profits Plan 

The Net Profits Plan is a standalone liability for which there is no available market price, principal 
market, or market participants.  The inputs available for this instrument are unobservable, and therefore classified 
as Level 3 inputs.  The Company employs the income approach, which converts expected future cash flow 
amounts to a single present value amount.  This technique uses the estimate of future cash payments, expectations 
of possible variations in the amount and/or timing of cash flows, the risk premium, and nonperformance risk to 
calculate the fair value.  There is a direct correlation between realized oil and gas commodity prices driving net 
cash flows and the Net Profits Plan liability.  If commodity prices fall, the liability is reduced or eliminated. 

The Company records the estimated fair value of the long-term liability for estimated future payments 

under the Net Profits Plan based on the discounted value of estimated future payments associated with each 
individual pool.  The calculation of this liability is a significant management estimate.  For a predominate number 
of the pools, a discount rate of 12 percent is used to calculate this liability.  This rate is intended to represent the 
best estimate of the present value of expected future payments under the Net Profits Plan. 

The Company’s estimate of its liability is highly dependent on commodity price and cost assumptions and 

the discount rates used in the calculations.  The Company continually evaluates the assumptions used in this 
calculation in order to consider the current market environment for oil and gas prices, costs, discount rates, and 
overall market conditions.  For 2008 and prior the commodity price assumptions were formulated by applying a 
price that was derived from a rolling average of actual prices realized in the 24 months prior to the reporting date 
together with adjusted NYMEX strip prices for the ensuing 12 months.  This average price was adjusted to 
include the effect of hedge prices for the percentage of forecasted production hedged in the relevant periods.  Due 
to significant fluctuations in commodity prices over the past two years the Company no longer believes this 
method for computing commodity price assumptions produces the best estimate of future prices.  The 
December 31, 2009, Net Profits Plan liability was determined using price assumptions that were computed using  
five one-year strip prices with the fifth year’s pricing being carried out indefinitely.  The Company’s management 
believes the change in accounting estimate is appropriate and provides a better estimation of the liability.  The 
average price is still adjusted to include the effects of hedging.  The non-cash expense associated with this 
significant management estimate is highly volatile from period to period due to fluctuations that occur in the 
crude oil and natural gas commodity markets. 

If the commodity prices used in the calculation changed by five percent, the liability recorded at 
December 31, 2009, would differ by approximately $14 million.  A one percentage point decrease in the discount 
rate would result in an increase to the liability of approximately $9 million, while a one percentage point increase 
in the discount rate would result in a decrease to the liability of approximately $8 million.  Actual cash payments 
to be made to participants in future periods are dependent on realized actual production, realized commodity 
prices, and costs associated with the properties in each individual pool of the Net Profits Plan.  Consequently, 
actual cash payments are inherently different from the amounts estimated. 

F-43 

 
 
 
No published market quotes exist on which to base the Company’s estimate of fair value of the Net 

Profits Plan liability.  As such, the recorded fair value is based entirely on management estimates that are 
described within this footnote.  While some inputs to the Company’s calculation of fair value on the Net Profits 
Plan’s future payments are from published sources, others, such as the discount rate and the expected future cash 
flows, are derived from the Company’s own calculations and estimates.  The following table reflects the activity 
for the liabilities measured at fair value using Level 3 inputs:

3.50% Senior Convertible Notes Due 2027 

Based on the market price of the 3.50% Senior Convertible Notes, the estimated fair value of the notes 

was approximately $290.0 million and $204.0 million as of December 31, 2009 and 2008, respectively.  The fair 
value of the embedded contingent interest derivative as of December 31, 2009, and 2008, was zero. 

Proved Oil and Gas Properties 

Proved oil and gas property costs are evaluated for impairment and reduced to fair value if the sum of the 

expected undiscounted future cash flows is less than net book value pursuant to ASC Topic 360.  The Company 
uses Level 3 inputs and the income valuation technique, which converts future amounts to a single present value 
amount, to measure the fair value of proved properties through an application of discount rates and price forecasts 
selected by the Company’s management.  The calculation of the discount rate is a significant management 
estimate based on the best information available and computed to be 12 percent for the year ended 
December 31, 2009.  Management believes that the discount rate is representative of current market conditions 
and includes the following factors: estimate of future cash payments, expectations of possible variations in the 
amount and/or timing of cash flows, the risk premium, and nonperformance risk.  The price forecast is based on 
NYMEX strip pricing, adjusted for basis differentials, for the first five years.  Future operating costs are also 
adjusted as deemed appropriate for these estimates. 

In accordance with ASC Topic 820, of the $2.1 billion worth of long-lived assets, excluding materials 

inventory, $11.7 million were measured at fair value at December 31, 2009. 

Materials Inventory 

Materials inventory is valued at the lower of cost or market.  The Company uses Level 2 inputs to 
measure the fair value of materials inventory, which is primarily comprised of tubular goods.  The Company uses 
third party market quotes and compares the quotes to the book value of the materials inventory.  If the book value 
exceeds the quoted market price, the Company reduces the book value to the market price.  The considered factors 
result in an estimated exit-price that management believes provides a reasonable and consistent methodology for 
valuing materials inventory. 

In accordance with ASC Topic 820, of the $24.5 million of materials inventory, $13.9 million was 

measured at fair value at December 31, 2009.

Asset Retirement Obligations 

The Company estimates asset retirement obligations pursuant to the provisions of ASC Topic 410.  The 
income valuation technique is utilized by the Company to determine the fair value of the liability at the point of 
inception by applying a credit-adjusted risk-free rate, which takes into account the Company’s credit risk, the time 
value of money, and the current economic state, to the undiscounted expected abandonment cash flows.  Given 
the unobservable nature of the inputs, the initial measurement of the asset retirement obligation liability is deemed 
to use Level 3 inputs.  There were no asset retirement obligations measured at fair value within the accompanying 
consolidated balance sheets at December 31, 2009. 

Please refer to Note 10 – Derivative Financial Instruments and Note 9 – Asset Retirement Obligations for 
more information regarding the Company’s hedging instruments and asset retirement obligations, as well as Note 
8 - Pension Benefits for additional fair value discussion. 

Note 12 – Repurchase and Retirement of Common Stock 

Stock Repurchase Program 

In July 2006 the Company’s Board of Directors approved an increase of 5,473,182 shares to the 

remaining authorized number of shares that can be repurchased under the Company’s original authorization 
approved in August 1998, for a total number of shares authorized to be repurchased under the plan of 6,000,000.  
As of the date of this filing, the Company has Board authorization to repurchase up to 3,072,184 shares of 
common stock.  The shares may be repurchased from time to time in open market transactions or in privately 
negotiated transactions, subject to market conditions and other factors, including certain provisions of St. Mary’s 
existing credit facility agreement and compliance with securities laws.  Stock repurchases may be funded with 
existing cash balances, internal cash flows, and borrowings under the credit facility.  The details for shares 
repurchased and retired are summarized as follows:

Note 13 – Hurricanes 

In 2008 assets in which the Company has an interest were impacted by Hurricanes Gustav and Ike.  The 

Company incurred damage to two wells and to its production facilities located at Goat Island in Galveston Bay 
and minor damages to several other properties.  The Vermilion 281 production platform was lost in Hurricane Ike.  
The Company made use of its insurance coverage with regards to the lost platform and damage to several other 
properties.  Due to the severe damage caused by the hurricanes, the total storm related costs exceeded the 
maximum insurance policy limit.  As a result, the Company recorded losses of $8.3 million and $7.0 million in 
other expense in the accompanying consolidated statements of operations for the years ended December 31, 2009 
and 2008, respectively.  To date, the Company has received $16.8 million in insurance proceeds.  Any variation 
between actual and estimated storm related costs will impact the final determination of the loss. 

In April 2007 the Company reached a global insurance settlement for reimbursement of damages 
sustained during Hurricane Rita in 2005.  St. Mary’s net cash received in the final settlement was approximately 
$33 million.  The Company recorded a loss of $2.3 million and a gain of $5.2 million in other revenue in the 
accompanying consolidated statements of operations for the years ended December 31, 2008, and 2007,

December 31, 2008. 

Note 14 – SemGroup Bankruptcy 

On July 22, 2008, SemGroup, L.P. and certain of its North American subsidiaries (collectively referred to 

herein as “SemGroup”) filed voluntary petitions for reorganization under Chapter 11 of the United States 
Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware.  At that time, certain 
SemGroup entities purchased a portion of the Company’s crude oil production.  As a result of the SemGroup 
bankruptcy filing the Company recorded an allowance for doubtful accounts and bad debt expense of 
$16.6 million as of December 31, 2008. 

On October 27, 2009, the Company executed a Purchase and Sale Agreement whereby the Company sold 
a portion of its SemGroup administrative claim under Section 503(b)(9) of the Bankruptcy Code.  The Company 
recorded a recovery of bad debt expense within the accompanying consolidated statements of operations for the 
year ended December 31, 2009.  The Company deemed the remaining accounts receivable balance relating to 
SemGroup to be uncollectible.  As a result of this determination, the Company wrote off the allowance for 
doubtful accounts and the accounts receivable balance as of December 31, 2009.  This matter is complete as of 
December 31, 2009, and did not have a material adverse effect on the Company’s liquidity or overall financial 
position.

Note 16 – Disclosures about Oil and Gas Producing Activities (Unaudited) 

Recent SEC and FASB Guidance 

In December 2008 the SEC published the final rules and interpretations updating its oil and gas reporting 

requirements.  The Company adopted the rules effective December 31, 2009, and the rule changes, including 
those related to pricing and technology, are included in the Company’s reserve estimates. 

In January 2010 the FASB aligned ASC Topic 932, with the aforementioned SEC requirements.  Please 

refer to the section entitled Recently Issued Accounting Standards under Note 1 – Summary of Significant 
Accounting Policies for additional discussion regarding both adoptions. 

Application of the new rules resulted in the use of lower prices at December 31, 2009, for both oil and gas 
than would have resulted under the SEC’s previous methodology.  Using 12-month average commodity prices the 
Company’s estimated proved reserves were 772.2 BCFE at December 31, 2009, compared to estimated proved 
reserves of 865.5 at December 31, 2008.  Using year-end commodity prices, as required under the SEC’s previous 
methodology, would have resulted in estimated proved reserves of 897.2 BCFE at December 31, 2009.  
Therefore, the total impact of the new SEC price methodology was a negative 125 BCFE.

Third-party Reserves Audit 

The Company engaged Ryder Scott Company, L.P. to review internal engineering estimates for at least 80 

percent of the PV-10 value of our proven conventional oil and gas reserves in 2009, 2008, and 2007.  For 2008 
and 2007, Netherland, Sewell and Associates, Inc. prepared the reserve information for the Company’s coalbed 
methane projects at Hanging Woman Basin in the northern Powder River Basin and St. Mary’s non-operated 
coalbed methane interest in the Green River Basin.  The Company divested of all Hanging Woman Basin 
properties in the fourth quarter of 2009.  Please refer to the section entitled Third-party Reserves Audit under the 
heading Reserves included in Part I, Items 1. and 2. Business and Properties. 

Oil and Gas Reserve Quantities 

Proved oil and gas reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids, 

which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be 
economically producible – from a given date forward, from known reservoirs, and under existing economic 
conditions, operating methods, and government regulations – prior to the time at which contracts providing the 
right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether 
deterministic or probabilistic methods are used for the estimation.  Existing economic conditions include prices 
and costs at which economic producibility from a reservoir is to be determined, and the price to be used is the 
average price during the 12-month period prior to the ending date of the period covered by the report, determined 
as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless 
prices are defined by contractual arrangements, excluding escalations based upon future conditions.  With respect 
to reserves as of dates prior to December 31, 2009, the applicable SEC definition of proved reserves was the 
estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data 
demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing 
economic and operating conditions, meaning prices and costs as of the date the estimate is made.  All of the 
Company’s proved reserves are located in the continental United States. 

The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new 

discoveries and undeveloped locations are more imprecise than estimates of established producing oil and gas 
properties.  Accordingly, these estimates are expected to change as future information becomes available.

(a)  For the year ended December 31, 2009, of the 49.6 BCFE downward revision of previous estimate, 12.0 BCFE and (61.6) BCFE 
relate to price and performance revisions, respectively.  The largest portion of the performance revision related to producing 
properties in the Company’s Wolfberry tight oil program in the Permian Basin in West Texas.  Well performance data collected 
during 2009 at the Sweetie Peck and Halff East programs that target the Wolfberry interval indicate that these assets are 
underperforming for year-end 2008 decline forecasts.  Accordingly, the Company removed 37 BCFE from proved reserves in the 
Permian region, primarily related to the Wolfberry tight oil program.  The Company believes that a significant portion of these 
reserves, while not meeting the criteria to be booked as proved reserves at year-end, are likely to eventually be produced.  The 
Company also saw a downward performance revision of 12 BCFE related to certain Cotton Valley assets in our ArkLaTex region.  
For the year ended December 31, 2008, of the 244.2 BCFE downward revision of previous estimate, 199.7 BCFE and 44.5 BCFE 
relate to price and performance revisions, respectively.  For the year ended December 31, 2007, of the 40.9 BCFE upward revision of 
previous estimate, 34.5 BCFE and 6.4 BCFE relate to price and performance revisions, respectively. 

(b)  The Company divested of certain non-core assets during 2009, 2008, and 2007.  Please refer to Note 3 - Acquisitions, Divestitures, 

and Assets Held for Sale for additional information. 

(c)  For the years ended December 31, 2009, 2008, and 2007, amounts included approximately 370, 659, and, 316 MMcf respectively, 

representing the Company’s net underproduced gas balancing position. 

Standardized Measure of Discounted Future Net Cash Flows 

The Company follows the guidelines prescribed in ASC Topic 932 for computing a standardized measure 
of future net cash flows and changes therein relating to estimated proved reserves.  Future cash inflows and future 
production and development costs are determined by applying prices and costs, including transportation, quality, 
and basis differentials, to the year-end estimated quantities of oil and gas to be produced in the future.  Each 
property the Company operates is also charged with field-level overhead in the estimated reserve calculation.  
Estimated future income taxes are computed using the current statutory income tax rates, including consideration 
for estimated future statutory depletion.  The resulting future net cash flows are reduced to present value amounts 
by applying a ten percent annual discount factor.

Future operating costs are determined based on estimates of expenditures to be incurred in developing and 

producing the proved oil and gas reserves in place at the end of the period using year-end costs and assuming 
continuation of existing economic conditions, plus Company overhead incurred by the central administrative 
office attributable to operating activities. 

The assumptions used to compute the standardized measure are those prescribed by the FASB and the 

SEC.  These assumptions do not necessarily reflect the Company’s expectations of actual revenues to be derived 
from those reserves, nor their present value.  The limitations inherent in the reserve quantity estimation process, 
as discussed previously, are equally applicable to the standardized measure computations since these reserve 
quantity estimates are the basis for the valuation process.  The following prices as adjusted for transportation, 
quality, and basis differentials were used in the calculation of the standardized measure:
