PROGRESS MEETS VALUE

As Whiting enters a new decade, we find ourselves in the midst of an onshore 
revolution for oil and gas. The industry is changing rapidly, and Whiting 
is prepared to stand apart and lead because we understand the external 
environment and continue to take a long-term outlook. We know our investors 
have the opportunity to earn returns from virtually any source. We take the 
competition seriously and strive to provide transparency, disclosure, and an 
easy-to-understand capital structure.

As we look to 2020, you’ll see us continue to deliver value 
in a number of ways, as we make every effort to generate  
cash flow, provide returns to our investors, and pay down 
debt. We’re working tirelessly to create cash flow growth, 
improve  margins,  and  increase  efficiency.  Yet,  we’ll  
never  position  ourselves  as  just  a  low-cost  operator,  
because  we  refuse  to  compromise.  Throughout  this  
report, you’ll find that our commitment to our values, our 
investors,  our  employees,  and  our  communities  never 
wavers. At the end of the day, that’s how we’ll deliver the 
greatest value to all.

Sincerely,

BRADLEY J. HOLLY

Chairman, President and  
Chief Executive Officer

Ultimately, the question is this: Who can generate value? 
Whiting  has  answered  the  call  with  our  transition  to  a 
free cash flow model. For us, this isn’t a trend, but rather  
the right way to do business. It required us to embrace  
significant  change 
isn’t  necessarily  
in  2019,  which 
simple in a large, established organization, but as always,  
we  met  the  challenge  on  the  strength  of  our  people  
and culture.

Making  this  kind  of  sea  change  involved  an  economic 
evaluation of every aspect of our business. It meant taking 
a fresh look at how we spend on capital projects, existing 
projects, and general and administrative functions, with 
generating value as our guide at every turn. In this light, 
we identified the need for a restructuring, resulting in a 
flatter organization, key hires, and cultural adjustments.

From  an  operating  perspective,  we  saw  an  opportunity 
to generate more value from mature reservoirs. Not only 
did  we  apply  the  latest  technology  to  our  completions, 
we  also  centralized  reporting  for  all  field  operations  to  
streamline communications. From a financial point of view, 
we brought Correne Loeffler on board as Chief Financial 
Officer  to  contribute  strategic  leadership  to  finance  and 
accounting. She brought a wealth of experience, as well as 
an enthusiastic, high-energy approach to building a team 
with new ideas and a can-do attitude. 

We  approached  our  employees  in  different  ways,  too. 
Our compensation structure now aligns employees with 
shareholders,  providing  a  new  framework  for  decision-
making and performance which benefits all investors. At 
the same time, we reinvented our working environments.  
Whiting opened two new state-of-the-art offices. In North 
Dakota,  the  office  is  closer  to  the  field,  shortening  
commutes  and  supporting  employees  with  automated 
tools. And for the first time, our Denver office moved to a 
new space at equal cost. More than a hundred of our own 
Whiting  employees  helped  to  design  our  modern  and  
inspiring offices, filled with cutting-edge tools and collab-
orative spaces that encourage productive interaction. It’s a 
place we can all function even better than before.

STRATEGY MEETS TRANSPARENCY

In 2019, I joined Whiting as our industry faced a significant transformation. 
Thankfully, Whiting is an established organization with people, processes, 
and groups that work well together, translating to the field, where 2,171 
wells produced 125 thousand BOE per day in 2019. In addition, Whiting’s 
large asset base gives us a strong competitive advantage, with 65%  
of production in oil.

At the same time, we must evolve to meet new 
challenges. In a volatile commodities market, 
it’s  essential  to  maximize  every  dollar  and 
achieve the highest, most efficient production 
possible. To continue as a premier producer in 
this  environment  requires  cost  discipline,  so 
we’re able to take advantage of opportunities 
as soon as they emerge.

To  that  end,  we  are  building  a  new  strategic  
financial  organization  focused  on  strength-
ening  our  planning  capabilities,  facilitating 
greater in-depth understanding of the business, 
implementing real-time dashboards, and build-
ing  bridges  between  finance,  accounting,  and  

operations  by  communicating  all  of  this  infor-
mation.  Our  guiding  principle  is  transparency,  
both  internally  and  externally.  We  want  our  
employees  to  know  how  and  why  we  work  in 
certain  ways,  so  departments  can  understand 
each  other.  Beyond  the  walls  of  the  company, 
we  want  our  investors  to  know  they  can  trust  
us, especially in an industry where trust is in 
jeopardy.

Every  day,  our  proactive  leadership  team 
continues  to  move  Whiting  away  from  a  
production-only  mindset  by  looking  for  new 
and  different  ways  to  generate  value  and  
deliver  returns  for  our  investors.  Through 
our operational efficiency efforts we reduced 
lease  operating expense and G&A by approxi-
mately $100 million on an annualized basis in 
the second half of 2019  from second quarter 
levels. 

As  2020  takes  shape,  we  know  where  we’re  
going, and with our smarter approach to using 
information and encouraging communication, 
we know how to get there. Whiting is position-
ing  ourselves  to  control  our  own  destiny  like 
never before.

Sincerely,

CORRENE LOEFFLER

Chief Financial Officer

CULTURE MEETS COMMITMENT

Whiting remains committed to a company culture that values 
high integrity, engaged leadership, business excellence, effective 
communication, meaningful stewardship and safety always.

This  requires  a  consistent  and  dedicated  approach  to  developing  our  employees  
personally and professionally. An important way we accomplish this objective is through 
WLL Lead. The goal of WLL Lead is to increase employee engagement and foster more 
effective  leadership  throughout  the  organization.  Employees  who  participate  in  the 
program  receive  classroom  training  every  six  weeks,  and  most  collaborate  with  an 
executive coach during a monthly one-on-one meeting. Approximately 52 employees 
completed the WLL Lead program in 2019.

At Whiting, “safety always” is our core value. Our goal is zero incidents every single 
day. To foster this culture of safety, we promote transparency and accountability, while 
providing tools and resources to empower our people to identify and report potential 
hazards  and  stop  work  when  necessary.  To  further  instill  the  value  of  safety  always, 
Whiting holds quarterly meetings with employees and contractors to ensure effective 
communication and a continuous focus on safety. Maintaining the safety of our employees, 
contractors, and communities will not be compromised.

H I G H   S TA N DA R D S   M E E T   R E C O G N I T I O N

Whiting’s  core  values  provide  the  foundation  for  how  we  work,  interact,  manage,  and 
lead. In 2019, we formed a committee to recognize employees who exemplify our values.  
Each  quarter,  employees  nominate  colleagues  who  best  represent  one  of  Whiting’s  
six core values, and the committee reviews all nominations and selects a winner for 
each  value.  In  2019,  an  incredible  347  values  nominations  were  received,  proving  
Whiting  employees  hold  themselves  and  others  to  the  highest  standards  of  integrity, 
accountability, and performance.

2019 brought drastic weather conditions to our properties. 

The  way  our  people  responded  tells  you  everything  about 

how  we  do  business  at  Whiting.  In  the  first  quarter,  the 

field experienced record-low temperatures, but production 

continued  without  complaint.  Next  came  the  Yellowstone 

floods.  The  team  worked  tirelessly  to  make  sure  our 

emergency response was ready and prepared. In the third 

quarter, heavy rains led to knee-deep mud and shut-down 

roads, blocking equipment. Through it all, the passion and 

pride  to  do  things  right  kept  production  going  safely.  But 

personal and professional development doesn’t end there. 

We  also  support  every  employee  in  honing  their  business 

perspective,  so  they  know  how  they  impact  production 

and  create  value  for  the  company  and  investors.  Applying 

technology  has  strengthened  this  understanding  and 

improved operational efficiency. Implementing dashboards 

provides the field with real-time data. Modern completions 

enable us to produce for less cost, creating opportunities to 

build infrastructure like oil, gas, and water takeaways. 

After two strong quarters at the end of 2019, we’re striving 

to keep the winning streak going through all four quarters 

of 2020. This means operating at a low cost, while earning 

the  best  selling  price.  Maximizing  base  production,  while 

minimizing  downtime.  All  with  the  purpose  of  getting  the 
most value from every barrel—while keeping everyone safe. 
We’ll never sacrifice that.

OPERATIONS MEET OPTIMIZATIONS

With control of approximately 476,000 net acres, we’re one of 
the largest producers in the oil-rich Williston Basin of North 
Dakota and Montana, encompassing the prolific Bakken and 
Three Forks formations. Whiting remains on the forefront of 
the industry in the application of optimized completions, a 
key factor in our ability to expand top-tier results outside the 
established core of the Bakken.

POD 8

POD 9

POD 10

At the Pod 8 project, infill Bakken and Three Forks wells have outper-
formed  parent  wells  by  approximately  160%  and  230%,  respectively, 
after 180 days on production. Parent wells have experienced a marked 
increase in production relative to the trend prior to infill drilling.

The Bakken wells drilled in the Bartelson unit, located at the far western 
edge of the Sanish Field, have outperformed the parent well by 244% 
after  180  days  on  production.  The  parent  well  in  the  Bartelson  area 
saw  a  substantial  and  sustained  positive  response  to  infill  drilling, 
flowing for over four months after the new completions. 

Whiting also brought on the Pod 9 infill pilot, located in the northwest 
portion of the Sanish field. At Pod 9, Whiting drilled nine Bakken wells 
in  an  area  that  had  11  parent  wells.  The  average  well  produced  760 
barrels  of  oil  equivalent  per  day  (BOE/d)  over  the  first  90  days  and  
continues  to  produce  with  moderate  decline.  The  new  wells  are  
producing above the parent wells, and the parent wells are producing 
above  their  prior  trend  due  to  positive  stimulation  from  child  wells.  
To  date,  Whiting  has  completed  multiple  successful  infill  pilots  that 
span the field and demonstrate the potential for a full-scale redevelop-
ment program. 

Pod  10  represents  the  latest  evolution  of  infill  development  in  the  
Sanish  Field.  It  spans  two  1,280-acre  drilling  spacing  units  with  16 
parent  wells  and  10  child  wells.  Based  on  prior  infill  pilot  results, 
the  Company  optimized  proppant  and  fluid  volumes  and  modified  its  
artificial lift program. On average, cumulative production per well from 
Pod 10 is trending higher than Pod 9 production results. Performance 
relative  to  parent  wells  has  also  been  superior,  with  average  30-day 
cumulative rates for child wells 45% above the parent trend.

CASSANDRA

In  the  Northern  Williston  Basin,  the  Periot  wells  located  in  the  
Cassandra area continue to deliver strong results. With over 100 days 
on  production,  Bakken  and  Three  Forks  wells  have  outperformed  
competitor wells by 37% and 48%, respectively. Also, construction on 
the Ray gas plant was completed during the year. This additional gas 
capacity supported accelerated activity in the Polar area in 2019, as 
well as supporting future activity in the Cassandra area. 

HIDDEN 
BENCH 

In  the  Southern  Williston  Basin,  the  Stenehjem  wells  in  southern  
Hidden Bench continue to outperform parent wells. With more than 80 
days on production, the Stenehjem wells have generated 90,000 barrels 
of oil per well on average—a 124% increase relative to parent results. 

FOREMAN 
BUTTE

Whiting  acquired  the  Foreman  Butte  property  in  2018  and  has  now  
completed its delineation program, establishing production from the first 
17  wells  in  the  field.  These  wells  produced  2.5x  above  the  offset  wells 
drilled  in  the  area.  Whiting  is  currently  working  with  third  parties  to  
install gathering infrastructure in preparation for full field development.

Delivering  value  through  an  integrated  and  collaborative 

approach  to  business  planning  and  use  of  supply  chain 

practices is key to our operations.

First,  Whiting  has  developed  strong  procurement  policies 

that  allow  us  to  maximize  the  value  we  receive  for  each  

dollar we spend with our suppliers. These policies generate 

savings  and  reduce  supplier  risk,  while  holding  suppliers  

accountable.  In  addition,  Whiting  makes  every  effort  to  

competitively  bid  high-volume  and  frequently  purchased 

goods and services while consolidating awarded goods and 

services over a period (e.g., quarterly, semi-annually). 

Our policies also help Whiting maintain strong relationships 

with our employees, suppliers and communities, who have 

become an essential part of why and how we do business. 

Due  to  the  remote  nature  of  many  of  our  operations,  we  

often  hire  locally  for  services  on  our  locations  from  

reputable  small  businesses,  whose  employees  live  in  the 

communities  nearby.  Providing  scheduling  and  financial 

certainty  to  local  suppliers  and  contractors  can,  in  turn, 

help them with employee retention and business planning. 

We also keep our communities top of mind as we screen 

waste disposal and injection vendors based on our Waste 

Management  Program.  We  maintain  Environmental  

Addendums  (EAs)  associated  with  our  Master  Service  

Agreements for generator and compressor rental vendors, 

and we piloted software to track vendors’ movements and 

where they deliver waste. The software is designed to help 

select which waste vendors provide goods and services to 

Whiting, and to provide additional assurance that Whiting’s 

waste is handled properly.

Finally,  since  2018,  Whiting  has  been  using  safety  per-

formance as a component in vendor selection. We screen 

contractors  for  safety-related  items  via  ISNetworld,  an 

online  contractor  and  supplier  management  platform 

that  manages  risk  and  reduces  unnecessary  duplication  

associated with traditional vendor qualification processes.

PASSION MEETS VISION

Whiting continues to build on its commitment to sustainability  
planning, reporting, and execution. We have increased transparency, 
achieved tangible progress, and maintained a strong resolve to 
advance key initiatives. As challenges to our industry grow, our 
dedication to our people, the communities where we live and work, 
and the environment we all value and enjoy, only increases.

A I R   E M I S S I O N S 

Consistent with our overall commitment to environmental responsibility, Whiting seeks to limit 
and  capture  air  emissions.  Whiting  estimates  the  air  emissions  from  our  operations  by  using 
state and federal emission estimation methodologies relevant to the locations in which Whiting 
operates,  along  with  manufacturer-provided  or  EPA-required  emissions  factors.  Ongoing 
initiatives include improving our gas capture rate in North Dakota, implementing pilot emissions 
reduction initiatives, pursuing the most advantageous emissions calculation method and devel-
oping a greenhouse gas (GHG) emissions reduction target.

R I S K   M A N A G E M E N T 

At  Whiting,  protecting  the  health  and  safety  of  our  employees  is  paramount  in  sustaining  a  
culture that values caring for others, quality of work, productivity and company pride. Our Health 
and  Safety  programs  are  designed  to  guide  employees  in  the  recognition  of  hazards  and  the  
assessment  of  those  risks  inherent  to  our  industry.  Through  Health  and  Safety  training,  we  
prepare our employees to use industry best practices and consensus standards to mitigate risk 
in  a  manner  that  protects  themselves,  co-workers,  the  public,  and  our  property.  Ongoing  
initiatives  include  formalizing  risk  management  process,  standardizing  operating  procedures, 
and consistently reviewing Whiting’s position on climate risk.

W AT E R   M A N A G E M E N T 

Whiting  understands  and  respects  water  as  a  limited  natural  resource,  and  is  committed  to  
responsible  water  use.  We  recognize  that  our  water  use  affects  neighboring  communities,  
governments, businesses and industries, and we remain dedicated to using water responsibly 
and  effectively  while  developing  energy  resources.  Whiting  strives  to  obtain  fresh  water  from 
nearby water resources, and to minimize water consumption by only using the necessary volume 
of fresh water. Where possible, we utilize pipelines to transport fresh water, which eliminates 
the  use  of  haul  trucks  and  their  associated  emissions  and  road  traffic.  Ongoing  initiatives  
include  enhancing  the  water  data  collection  process,  completing  a  water  risk  assessment,  
developing water reduction and recycling initiatives and creating a water reduction target.

W A S T E   M A N A G E M E N T 

Whiting has developed an effective waste management program in order to minimize our impact 
on the environment and to limit the risk and liability of handling and disposing waste. Our corporate 
Waste Management and Minimization Plan and third-party audits of all disposal locations ensure 
that waste generated at all our locations is properly disposed of or treated. Whiting’s waste manage-
ment program is always evolving and looking for new ways to improve how we manage and dispose 
of our wastes and reduce the amount of wastes we generate. Ongoing initiatives include enhancing 
the  waste  data  collection  process,  creating  a  baseline  using  2020  data,  developing  and  piloting 
waste reduction initiatives, and leveraging supply chain to consolidate vendors.

impervious strata, or laterally by local geologic barriers, or both.  Reservoirs that are associated by being in overlapping or adjacent 
fields may be treated as a single or common operational field.  The geological terms “structural feature” and “stratigraphic condition” 
are intended to identify localized geological features as opposed to the broader terms of basins, trends, provinces, plays, areas of interest, 
etc.

“PDNP” Proved developed nonproducing reserves. 

“PDP” Proved developed producing reserves. 

“plugging and abandonment” Refers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum 
will not escape into another or to the surface.  Regulations of most states legally require plugging of abandoned wells. 

“pre-tax PV10%” The present value of estimated future revenues to be generated from the production of proved reserves calculated in 
accordance with the guidelines of the SEC, net of estimated lease operating expense, transportation, gathering, compression and other 
expense, production taxes and future development costs, using costs as of the date of estimation without future escalation and using an 
average of the first-day-of-the-month price for each of the 12 months within the fiscal year, without giving effect to non-property related 
expenses such as general and administrative expenses, debt service and depreciation, depletion and amortization, or federal income taxes 
and discounted using an annual discount rate of 10%.  Pre-tax PV10% may be considered a non-GAAP financial measure as defined by 
the  SEC.    Refer  to  the  footnote  to  the  Proved  Reserves  table  in  Item 1.  “Business”  of  this  Annual  Report  on  Form 10-K  for  more 
information. 

2 

“probabilistic method” The method of estimating reserves using the full range of values that could reasonably occur for each unknown 
parameter (from the geoscience and engineering data) to generate a full range of possible outcomes and their associated probabilities of 
occurrence.  

“prospect” A property on which indications of oil or gas have been identified based on available seismic and geological information. 

“proved developed reserves” Proved reserves that can be expected to be recovered 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. 

“proved reserves” Those reserves 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.  The project 
to extract the hydrocarbons must have commenced, or the operator must be reasonably certain that it will commence the project, within 
a reasonable time. 

The area of the reservoir considered as proved includes all of the following: 

a. 

b. 

The area identified by drilling and limited by fluid contacts, if any, and 

Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and 
to contain economically producible oil or gas on the basis of available geoscience and engineering data. 

Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluid 
injection) are included in the proved classification when both of the following occur: 

a. 

b. 

Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir 
as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using 
reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program 
was based, and 

The project has been approved for development by all necessary parties and entities, including governmental entities. 

Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined.  The price 
shall  be  the  average  price during the 12-month  period  before 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. 

“proved undeveloped reserves” or “PUDs” Proved 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.  Reserves on undrilled acreage shall be limited to 
those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable 
technology  exists  that  establishes  reasonable  certainty  of  economic  producibility  at  greater  distances.    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 specific circumstances justify a longer time.  Under no circumstances shall estimates of proved undeveloped 
reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, 
unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence 
using reliable technology establishing reasonable certainty. 

“reasonable certainty” If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities 
will be recovered.  If probabilistic methods are used, there should be at least a 90 percent probability that the quantities actually recovered 
will equal or exceed the estimate.  A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, 
as changes due to increased availability of geoscience (geological, geophysical and geochemical) engineering, and economic data are 
made to estimated ultimate recovery with time, reasonably certain estimated ultimate recovery is much more likely to increase or remain 
constant than to decrease. 

3 

“recompletion” An operation whereby a completion in one zone is abandoned in order to attempt a completion in a different zone within 
the existing wellbore. 

“reserves” Estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given 
date, by application  of  development  projects to  known accumulations.    In  addition,  there  must exist,  or  there  must  be  a  reasonable 
expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and 
gas or related substances to market, and all permits and financing required to implement the project. 

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

“resource play” An expansive contiguous geographical area with known accumulations of crude oil or natural gas reserves that has the 
potential  to be  developed uniformly  with  repeatable  commercial  success  due to  advancements in  horizontal  drilling  and  completion 
technologies. 

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

“royalty interest” An interest in an oil or natural gas property entitling the owner to shares of the crude oil or natural gas production 
free of costs of exploration, development and production operations. 

“SEC” The United States Securities and Exchange Commission. 

“standardized measure of discounted future net cash flows” or “Standardized Measure” The discounted future net cash flows relating 
to proved reserves based on the average price during the 12-month period before 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); current costs and statutory tax rates (to 
the extent applicable); and a 10% annual discount rate. 

“three-way collar” A combination of options: a sold call, a purchased put and a sold put.  The sold call establishes a maximum price 
(ceiling) to be received for the volumes under contract.  The purchased put establishes a minimum price (floor), unless the market price 
falls below the sold put (sub-floor), at which point the minimum price would be NYMEX plus the difference between the purchased put 
and the sold put strike price.   

“working interest” The interest in a crude oil and natural gas property (normally a leasehold interest) that gives the owner the right to 
drill, produce and conduct operations on the property and to a share of production, subject to all royalties, overriding royalties and other 
burdens and to all costs of exploration, development and operations and all associated risks. 

“workover” Operations on a producing well to restore or increase production.

Overview 

PART I 

We are an independent oil and gas company engaged in development, production, acquisition and exploration activities primarily in the 
Rocky Mountains region of the United States.  We were incorporated in the state of Delaware in 2003 in connection with our initial 
public offering. 

Since our inception, we have built a strong asset base through a combination of property acquisitions, development of proved reserves 
and  exploration  activities.    Our  current  operations  and  capital  programs  are  focused  on  organic  drilling  opportunities  and  on  the 
development  of  previously acquired properties,  specifically  on  projects  that  we believe  provide  the  greatest  potential  for  repeatable 
success  and  production  growth,  while  selectively  pursuing  acquisitions  that  complement  our  existing  core  properties,  such  as  the 
acquisition  discussed  below  under  “Acquisitions  and  Divestitures,”  and  exploring  other  basins  where  we  can  apply  our  existing 
knowledge and expertise to build production and add proved reserves.  As a result of lower crude oil prices during 2017 and 2018, we 
significantly reduced our level of capital spending and focused our drilling activity on projects that provide the highest rate of return, 
while closely aligning our capital spending with cash flows generated from operations.   During 2019, we focused on developing our 
large resource play in the Williston Basin of North Dakota and Montana, while continuing to closely align our capital spending with 
cash flows generated from operations.  We continually evaluate our property portfolio and sell properties when we believe that the sales 
price  realized  will  provide  an  above  average  rate  of  return  for  the  property  or  when  the  property  no  longer  matches  the  profile  of 
properties we desire to own, such as the asset sales discussed below under “Acquisitions and Divestitures.” 

As  of  December 31,  2019,  our estimated  proved  reserves totaled  485.4  MMBOE  and  our 2019  average  daily  production  was  125.5 
MBOE/d, which results in an average reserve life of approximately 10.6 years. 

The following table summarizes by core area, our estimated proved reserves as of December 31, 2019 with the corresponding pre-tax 
PV10% values, our fourth quarter 2019 average daily production rates, and our total standardized measure of discounted future net cash 
flows as of December 31, 2019:

(1)  Oil and gas reserve quantities and related discounted future net cash flows have been derived from an oil price of $55.69 per Bbl 
and a gas price of $2.58 per MMBtu, which were calculated using an average of the first-day-of-the-month price for each month 
within the 12 months ended December 31, 2019 as required by current SEC and FASB guidelines. 

(2)  Pre-tax PV10% may be considered a non-GAAP financial measure as defined by the SEC and is derived from the standardized 
measure of discounted future net cash flows (the “Standardized Measure”), which is the most directly comparable GAAP financial 
measure.  Pre-tax PV10% is computed on the same basis as the Standardized Measure but without deducting future income taxes.  
We  believe pre-tax  PV10% is a  useful  measure  for  investors  when evaluating the  relative monetary  significance  of  our  oil  and 
natural gas properties.  We further believe investors may utilize our pre-tax PV10% as a basis for comparison of the relative size 
and value of our proved reserves to other companies because many factors that are unique to each individual company impact the 
amount of future income taxes to be paid.  Our management uses this measure when assessing the potential return on investment

related to our oil and gas properties and acquisitions.  However, pre-tax PV10% is not a substitute for the Standardized Measure.  
Our  pre-tax  PV10%  and  Standardized  Measure do  not purport  to  present  the  fair  value  of  our  proved  oil,  NGL  and  natural  gas 
reserves. 

(3)  Includes oil and gas properties located in Montana and North Dakota. 

(4)  Includes oil and gas properties located in Colorado. 

(5)  Primarily includes non-core oil and gas properties located in Colorado, Mississippi, North Dakota, Texas and Wyoming. 

During 2019, we incurred $778 million in exploration and development (“E&D”) expenditures, including $772 million for the drilling 
and completion of 210 gross (94.0 net) wells.   

Our current 2020 E&D budget is a range of $585 million to $620 million, which we expect to fund substantially with net cash provided 
by our operating activities and cash on hand.  To the extent net cash provided by operating activities is higher or lower than currently 
anticipated, we would generate more or less free cash flow than we currently anticipate, adjust our E&D budget accordingly, enter into 
agreements with industry partners, divest certain oil and gas property interests, adjust borrowings outstanding under our credit facility 
or access the capital markets as necessary. 

Acquisitions and Divestitures 

2019 Acquisitions and Divestitures.  In July 2019, we completed the divestiture of our interests in 137 non-operated, producing oil and 
gas wells located in McKenzie, Mountrail and Williams counties of North Dakota for aggregate sales proceeds of $27 million (before 
closing adjustments).   

In  August 2019,  we  completed  the  divestiture  of  our  interests  in  58  non-operated,  producing  oil  and  gas  wells  located  in  Richland 
County, Montana and Mountrail and Williams counties of North Dakota for aggregate sales proceeds of $26 million (before closing 
adjustments). 

On a combined basis, the divested properties consisted of less than 1% of our estimated proved reserves as of December 31, 2018 and 
our April 2019 average daily production. 

There were no significant acquisitions during the year ended December 31, 2019. 

2018 Acquisitions  and  Divestitures.   In July 2018,  we completed  the  acquisition  of  approximately  54,800  net  acres  in the  Williston 
Basin,  including  interests  in  117  producing  oil  and  gas  wells  and  undeveloped  acreage  located  in  Richland  County,  Montana  and 
McKenzie County, North Dakota for an aggregate purchase price of $130 million (before closing adjustments).  The producing properties 
had estimated proved reserves of 25.7 MMBOE as of the acquisition date, 84% of which were crude oil and NGLs. 

There were no significant divestitures during the year ended December 31, 2018. 

Subsequent to December 31, 2019, we completed the divestiture of our interests in 30 non-operated, producing oil and gas wells and 
related undeveloped acreage located in McKenzie County, North Dakota for aggregate sales proceeds of $25 million (before closing 
adjustments).  The divested properties consisted of less than 1% of our estimated proved reserves as of December 31, 2019 and 1% of 
our average daily production for the year ended December 31, 2019.   

Business Strategy 

Our goal is to generate meaningful growth in shareholder value through the development, acquisition and exploration of oil and gas 
projects with attractive rates of return on capital.  Specifically, we have focused, and plan to continue to focus, on the following: 

Efficiently Developing Existing Properties.  The development of our large resource play at our Williston Basin project in North Dakota 
and  Montana continues  to  be  our  central  objective.  We  have assembled approximately 756,800  gross  (476,300  net)  developed and 
undeveloped acres in this area, on which we had four drilling rigs operating as of December 31, 2019.  During 2019, we completed and 

6 

brought on production 133 gross (87 net) operated Bakken and Three Forks wells in the Williston Basin.  Under our current 2020 capital 
program, we expect to put on production approximately 122 gross wells in this area during the year. 

At  our  Redtail  field  in  the  Denver-Julesburg  Basin  (the  “DJ  Basin”) in Weld  County,  Colorado,  we  have  assembled  approximately 
96,400 gross (84,600 net) developed and undeveloped acres.  We completed 22 drilled uncompleted wells (“DUCs”) in our Redtail field 
during the first half of 2018, and no additional wells were drilled or completed in 2019.  During 2019 we worked on maintaining base 
production with improved artificial lift techniques and reductions in lease operating expenses.  

Disciplined Financial Approach.  Our goal is to remain financially strong, yet flexible, through the prudent management of our balance 
sheet and active management of our exposure to commodity price volatility.  We have historically funded our acquisition and growth 
activity through a combination of internally generated cash flows, equity and debt issuances, bank borrowings and certain oil and gas 
property divestitures, as appropriate, to maintain our financial position.  As a result of lower crude oil prices during 2017 and 2018, we 
significantly reduced our level of capital spending and focused our drilling activity on projects that provide the highest rate of return, 
while closely aligning our capital spending with cash flows generated from operations.  During 2019, we focused on developing our 
large resource play in the Williston Basin of North Dakota and Montana, while continuing to closely align our capital spending with 
cash flows generated from operations.  From time to time, we monetize non-core properties and use the net proceeds from these asset 
sales to repay debt under our credit agreement or fund our E&D expenditures.  For example, during 2019 we sold certain oil and gas 
properties operated by third parties that no longer matched the profile of properties we desire to own.  In addition, to support cash flow 
generation on our existing properties and help ensure expected cash flows from newly acquired properties, we periodically enter into 
derivative contracts.  Typically, we use costless collars and swaps to provide an attractive base commodity price level.   

Growing Through Accretive Acquisitions.  Since 2010, we have completed 7 separate significant acquisitions of producing properties 
for total estimated proved reserves of 240.2 MMBOE, as of the effective dates of the acquisitions.  Our experienced team of management, 
business development, land, engineering and geoscience professionals has developed and refined an acquisition program designed to 
increase  reserves  and  complement  our  existing  properties,  including  identifying  and  evaluating  acquisition  opportunities,  closing 
purchases and effectively managing the properties we acquire.  We intend to selectively pursue the acquisition of properties that are 
complementary to our core operating areas, as well as explore opportunities in other basins where we can apply our existing knowledge 
and expertise to build production and add proved reserves. 

Competitive Strengths 

We believe that our key competitive strengths lie in our focused asset portfolio, our experienced management and technical teams and 
our commitment to the effective application of new technologies. 

Focused,  Long-Lived  Asset  Base.    As  of  December 31,  2019,  we  had  interests  in  5,021  gross  (2,171  net)  productive  wells  on 
approximately 824,200 gross (523,600 net) developed acres across our geographical areas.  We believe the concentration of our operated 
assets  presents  us  with multiple  opportunities to  successfully execute  our  business  strategy  by enabling  us  to leverage our technical 
expertise and take advantage of operational efficiencies.  Our proved reserve life is approximately 10.6 years based on year-end 2019 
proved reserves and 2019 production. 

Experienced Management and Technical Teams.  Our management team averages 23 years of experience in the oil and gas industry.  
Our personnel have extensive experience in each of our core geographical areas and in all of our operational disciplines.  In addition, 
our team of acquisition professionals has an average of 20 years of experience in the evaluation, acquisition and operational assimilation 
of oil and gas properties. 

Commitment to Technology.  In each of our core operating areas, we have accumulated extensive engineering, operational, geologic and 
geophysical technical knowledge.  Our technical team has access to an abundance of digital well log, seismic, completion,  production 
and other subsurface information, which is analyzed in order to accurately and efficiently characterize the anticipated performance of 
our oil and gas reservoirs.  In addition, our information systems enable us to update our production databases through field automation.  
This commitment to technology has increased the productivity and efficiency of our field operations and development activities. 

We continue to advance our completion techniques by utilizing customized, right-sized completion designs based on calibrated models 
for each of our prospect areas, using multivariate analysis to understand which completion factors most significantly impact the results 
in  each  area, and  piloting and adopting  the latest  completion  technologies available.    Such customized  designs  utilize the  optimum 
volume of proppant, diversion techniques, fluids and frac stages, allowing us to increase well performance while reducing cost.  We 

7 

have  increased  stages  pumped  per  day  by  focusing  on  new  technologies  such  as  quick-install  wellhead  connections  and  frac  plug 
innovations.  We plan to continue to use right-sized completion designs on wells we drill in 2020, while also utilizing state-of-the-art 
drilling rigs, high-torque mud motors and evolving 3-D bit cutter technology to reduce time-on-location and total well cost.

Marketing and Major Customers 

We principally sell our oil and gas production to end users, marketers and other purchasers that have access to nearby pipeline or rail 
takeaway.  In areas where there is no practical access to gathering pipelines, oil is trucked or transported to terminals, market hubs, 
refineries or storage facilities.  The tables below present percentages by purchaser that accounted for 10% or more of our total oil, NGL 
and natural gas sales for the years ended December 31, 2019, 2018 and 2017.  We believe that the loss of any individual purchaser

Our properties are subject to customary royalty interests, liens securing indebtedness, liens incident to operating agreements, liens for 
current taxes and other burdens, including other mineral encumbrances and restrictions.  Our credit agreement is also collateralized by 
a first lien on substantially all of our assets.  We do not believe that any of these burdens materially interfere with the use of our properties 
or the operation of our business. 

We believe that we have satisfactory rights or title to all of our producing properties.  As is customary in the oil and gas industry, limited 
investigation of title is made at the time of acquisition of undeveloped properties.  In most cases, we investigate title and obtain title 
opinions from counsel only when we acquire producing properties or before commencement of drilling operations. 

Competition 

The oil and gas industry is a highly competitive environment for acquiring properties, obtaining investment capital, securing oil field 
goods and services, marketing oil and natural gas products and attracting and retaining qualified personnel.  Many of our competitors 
possess and employ financial, technical and personnel resources substantially greater than ours, which can be particularly important in 
the areas in which we operate.  Those companies may be able to pay more for productive oil and gas properties and exploratory prospects 
and  to  evaluate,  bid  for  and  purchase  a  greater  number  of  properties  and  prospects  than  our  resources  permit.    In  addition,  the 
unavailability  or  high  cost  of  drilling  rigs  or  other  equipment  and  services  could  delay  or  adversely  affect  our  development  and 
exploration operations.  Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our 
ability  to  obtain  necessary  capital  as  well  as  evaluate  and  select  suitable  properties  and  to  consummate  transactions  in  a  highly 
competitive environment. 

In addition, the oil and gas industry as a whole competes with other industries in supplying the energy and fuel requirements of industrial, 
commercial and individual consumers.  The price and availability of alternative energy sources, such as wind, solar, nuclear and electric 
power, could adversely affect our revenue. 

Regulation 

Regulation of Production 

The production of oil and gas is subject to regulation under a wide range of local, state and federal statutes, rules, orders and regulations.  
Federal,  state and  local  statutes  and  regulations  require  permits  for  drilling  operations,  drilling  bonds  and  periodic  report  submittals 
during operations.  All of the states in which we own and operate properties have regulations governing conservation matters, including 
provisions for the unitization or pooling of oil and gas properties, the establishment of maximum allowable rates of production from oil 
and gas wells, the regulation of well spacing and the plugging and abandonment of wells.  The effect of these regulations is to limit the 
amount of oil and gas that we can produce from our wells and to limit the number of wells or the locations that we can drill, although 
we  can  apply  for  exceptions  to  such  regulations  or  to  have  reductions  in  well  spacing.    Moreover,  each  state  generally  imposes  a 
production or severance tax with respect to the production or sale of oil, NGLs and natural gas within its jurisdiction.

Currently, none of our production volumes are produced from offshore leases, however, some of our prior offshore operations were 
conducted on federal leases that are administered by the Bureau of Ocean Energy Management (the “BOEM”).   Among other things, 
BOEM regulations establish construction requirements for production facilities located on our federal offshore leases and govern the 
plugging  and  abandonment  of  wells  and  the  removal  of  production  facilities  from  these  leases.    The  present  value  of  our  future 
abandonment obligations associated with offshore properties was $41 million as of December 31, 2019.  We are therefore required to 
comply with the regulations and orders issued by the BOEM under the Outer Continental Shelf Lands Act.   

The  Bureau  of  Land  Management  (“BLM”) establishes the basis  for  onshore  royalty  payments  due under  federal  oil and  gas leases 
through  regulations  issued  under  applicable  statutory  authority.    State  regulatory  authorities  establish  similar  standards  for  royalty 
payments due under state oil and gas leases.  The basis for royalty payments established by the BLM and the state regulatory authorities 
is generally applicable to all federal and state oil and gas lessees.  Accordingly, we believe that the impact of royalty regulation on our 
operations should generally be the same as the impact on our competitors. 

Regulation of Sale and Transportation of Oil 

Sales of crude oil, condensate and NGLs are not currently regulated and are made at negotiated prices, however, Congress could reenact 
price controls or enact other legislation in the future. 

Our crude oil sales are affected by the availability, terms and cost of transportation.  The transportation of oil in common carrier pipelines 
is  also  subject  to  rate  regulation.    The  Federal  Energy  Regulatory  Commission  (the  “FERC”)  regulates  interstate  oil  pipeline 
transportation rates under the Interstate Commerce Act.  In general, interstate oil pipeline rates must be cost-based, although settlement 
rates agreed to by all shippers are permitted and market-based rates may be permitted in certain circumstances.  Effective January 1, 
1995, the FERC implemented regulations establishing an indexing system (based on inflation) for crude oil transportation rates that 
allowed for an increase or decrease in the cost of transporting oil to the purchaser.  The FERC’s regulations include a methodology for 
oil pipelines to change their rates through the use of an index system that establishes ceiling levels for such rates.  The most recent 
mandatory five-year review period resulted in a 2015 order from the FERC for the index to be based on Producer Price Index for Finished 
Goods (the “PPI-FG”) plus a 1.23% adjustment for the five-year period from July 1, 2016 through June 30, 2021.  This represents a 
decrease  from  the  PPI-FG  plus  2.65%  adjustment  from  the  prior  five-year  period.    The  FERC  determined  that  it  would  now  use  a 
calculation based on what it determined to be a superior data source, reflecting actual cost-of-service data as opposed to the accounting 
data historically used as a proxy for such information under the prior index methodology.  The regulations provide that each year the 
Commission will publish the oil pipeline index after the PPI-FG becomes available.  Intrastate oil pipeline transportation rates are subject 
to regulation by state regulatory commissions.  The basis for intrastate oil pipeline regulation and the degree of regulatory oversight and 
scrutiny given to intrastate oil pipeline rates varies from state to state.  Insofar as effective interstate and intrastate rates are equally 
applicable to all comparable shippers, we believe that the regulation of oil transportation rates will not affect our operations in any way 
that is of material difference from those of our competitors. 

Further,  interstate  and intrastate common carrier  oil  pipelines must  provide  service  on  a  non-discriminatory basis.   Under  this  open 
access  standard,  common carriers must  offer  service  to  all shippers  requesting  service  on  the  same  terms and  under the  same  rates.  
When oil pipelines operate at full capacity, access is governed by prorationing provisions set forth in the pipelines’ published tariffs.  In 
addition, the  FERC  has  emergency authority  under the  Interstate  Commerce  Act  to  intervene  and  direct  priority  use  of  oil  pipeline 
transportation  capacity,  and  the  FERC  exercised  this  authority  over  a  specific  pipeline  in  February 2014  in  response  to  significant 
disruptions  in  the  supply  of  propane.    Accordingly,  we  believe  that  access  to  oil  pipeline  transportation  services  generally  will  be 
available to us to the same extent as to our competitors. 

Transportation and safety of oil and hazardous liquid is subject to regulation by the Department of Transportation (the “DOT”) under 
the Pipeline Integrity, Protection, Enforcement and Safety Act of 2006 and the Pipeline Safety, Regulatory Certainty and Job Creation 
Act of 2012.  The Pipeline and Hazardous Material Safety Administration (“PHMSA”), an agency within the DOT, enforces regulations 
on all interstate liquids transportation and some intrastate liquids transportation.  The effect of regulatory changes under the DOT and 
their effect on interstate and intrastate oil and hazardous liquid transportation will not affect our operations in any way that is of material 
difference from those of our competitors. 

A portion of our crude oil production may be shipped to market centers using rail transportation facilities owned and operated by third 
parties.  The DOT, generally, and PHMSA, more specifically, establish safety regulations relating to crude-by-rail transportation.  In 
addition, third-party rail operators are subject to the regulatory jurisdiction of the Surface Transportation Board of the DOT, the Federal 

10 

Railroad  Administration  (the  “FRA”)  of  the  DOT,  the  Occupational  Safety  and  Health  Administration  and  other  federal  regulatory 
agencies.   

In response to rail accidents occurring between 2002 and 2008, the U.S. Congress passed the Rail Safety and Improvement Act of 2008, 
which implemented regulations governing different areas related to railroad safety.  In response to train derailments occurring in the 
United States and Canada in 2013 and 2014, U.S. regulators have taken a number of additional actions to address the safety risks of 
transporting crude oil by rail. 

In February 2014, the DOT issued an emergency order requiring all persons to ensure crude oil is properly tested and classed prior to 
offering such product into transportation, and to assure all shipments by rail of crude oil be handled as a Packing Group I or II hazardous 
material.  Also in February 2014, the Association of American Railroads entered into a voluntary agreement with the DOT to implement 
certain restrictions around the movement of crude oil by rail.  In May 2014 (and extended indefinitely in May 2015), the DOT issued an 
Emergency  Restriction/Prohibition  Order  requiring  each  railroad  carrier  operating  trains  transporting  1,000,000  gallons  or  more  of 
Bakken crude oil to provide notice to state officials regarding the expected movement of the trains through the counties in each state.  
The PHMSA and FRA have also issued safety advisories and alerts regarding oil transportation and have issued a report focused on the 
increased volatility and flammability of Bakken crude oil as compared with other crudes in the U.S.  In May 2015, PHMSA issued new 
rules applicable to  “high-hazard flammable trains,”  defined as a  continuous  block  of 20  or more tank  cars loaded  with a flammable 
liquid  or  35  or  more  tank  cars  loaded  with  a  flammable  liquid  dispersed  throughout  a  train.    Among  other  requirements,  the  new 
rules require enhanced standards for newly constructed tank cars and retrofitting of existing tank cars, restricted operating speeds, a 
documented testing and sampling program, and routine assessments that evaluate certain safety and security factors.  In December 2015, 
the Fixing America’s Surface Transportation (“FAST”) Act became law, further extending PHMSA’s authority to improve the safety of 
transporting flammable liquids by rail and pursuant to which new regulations phasing out the use of certain older rail cars were finalized 
in August 2016.  In June 2016, the Protecting our Infrastructure of Pipelines and Enhancing Safety (“PIPES”) Act became law.  The 
PIPES Act strengthens PHMSA’s safety authority, including an expansion of its ability to issue emergency orders, which was adopted 
by  rule in  October 2016  and  further  enhanced  by  rule  in  October  2019.    PHMSA  continues  to  review  further  potential  new  safety 
regulations under the PIPES Act and the FAST Act. 

We do not currently own or operate rail transportation facilities or rail cars.  However, the adoption of any regulations that impact the 
testing or rail transportation of crude oil could increase our costs of doing business and limit our ability to transport and sell our crude 
oil at favorable prices at market centers throughout the U.S., the consequences of which could have a material adverse effect on our 
financial condition, results of operations and cash flows.  The effect of any such regulatory changes will not affect our operations in any 
way that is of material difference from those of our competitors. 

Regulation of Transportation, Storage, Sale and Gathering of Natural Gas 

The FERC regulates the transportation and, to a lesser extent, the sale of natural gas for resale in interstate commerce pursuant to the 
Natural Gas Act of 1938 and the Natural Gas Policy Act of 1978 and regulations issued under those Acts.  In 1989, however, Congress 
enacted the Natural Gas Wellhead Decontrol Act, which removed all remaining price and non-price controls affecting wellhead sales of 
natural gas, effective January 1, 1993.  While sales by producers of natural gas can currently be made at unregulated market prices, in 
the future Congress could reenact price controls or enact other legislation with detrimental impact on many aspects of our business. 

Our  natural  gas  sales  are  affected  by  the  availability,  terms  and  cost  of  transportation.    The  price  and  terms  of  access  to  pipeline 
transportation and underground storage are subject to extensive federal and state regulation.  From 1985 to the present, several major 
regulatory changes have been implemented by Congress and the FERC that affect the economics of natural gas production, transportation 
and sales.  In addition, the FERC is continually proposing and implementing new rules and regulations affecting those segments of the 
natural  gas industry that  remain  subject to the  FERC’s  jurisdiction, most  notably  interstate natural  gas  transmission  companies  and 
certain  underground  storage  facilities.    These  initiatives  may  also  affect  the  intrastate  transportation  of  natural  gas  under  certain 
circumstances.  The stated purpose of many of these regulatory changes is to promote competition among the various sectors of the 
natural  gas  industry  by  making  natural  gas  transportation  more  accessible  to  natural  gas  buyers  and  sellers  on  an  open  and  non-
discriminatory basis. 

We cannot accurately predict whether the FERC’s actions will achieve the goal of increasing competition in the markets in which our 
natural gas is sold.  Regulations implemented by the FERC could result in an increase in the cost of transportation service on certain 
petroleum product pipelines.  In addition, the natural gas industry has historically been heavily regulated.  Therefore, we cannot provide 

11 

any assurance that the less stringent regulatory approach established by the FERC will continue.  However, we do not believe that any 
action taken will affect us in a way that materially differs from the way it affects other natural gas producers. 

Transportation and safety of natural gas is subject to regulation by the DOT under the Pipeline Inspection, Protection, Enforcement and 
Safety  Act of  2006 and  the  Pipeline  Safety,  Regulatory  Certainty  and Job  Creation  Act  of  2012.    In  addition, intrastate  natural  gas 
transportation  is  subject  to  enforcement  by  state  regulatory  agencies  and  PHMSA  enforces  regulations  on  interstate  natural  gas 
transportation.  State regulatory agencies can also create their own transportation and safety regulations as long as they meet PHMSA’s 
minimum requirements.   The  basis for intrastate  regulation  of  natural  gas transportation and  the  degree  of regulatory oversight and 
scrutiny given to intrastate natural gas pipeline rates and services varies from state to state.  Insofar as such regulation within a particular 
state will generally affect all intrastate natural gas shippers within the state on a comparable basis, we believe that the regulation of 
similarly situated intrastate natural gas transportation in any of the states in which we operate and ship natural gas on an intrastate basis 
will not affect our operations in any way that is of material difference from those of our competitors.  Likewise, the effect of regulatory 
changes by the DOT and their effect on interstate natural gas transportation will not affect our operations in any way that is of material 
difference from those of our competitors. 

The failure to comply with these rules and regulations can result in substantial penalties.  We use the latest tools and technologies to 
remain compliant with current pipeline safety regulations. 

In October 2015, a failure at an underground natural gas storage facility in Southern California prompted PHMSA to issue an advisory 
bulletin reminding owners and operators of underground storage facilities to review operations, identify the potential for facility leaks 
and failures and to review and update emergency plans.  The State of California proclaimed the underground natural gas storage facility 
an emergency situation in January 2016.  A federal task force was also convened to make recommendations to help avoid such failures.  
An interim final rule of PHMSA became effective in January 2017 which adopted certain specific industry recommended practices into 
Part 192 of the Federal Pipeline Safety Regulations.  PHMSA later reopened the post-promulgation comment period through November 
2017 in response to petitions for reconsideration and has stated it would consider such comments further when it adopts a final rule.  
Under the interim final rule, if an operator fails to take any measures recommended it would need to justify in its written procedures 
why the measure is impracticable and unnecessary.  PHMSA regulations had previously covered much of the surface piping up to the 
wellhead at underground natural gas storage facilities served by pipelines and did not extend in part to the “downhole” portion of these 
facilities.    The  adopted  requirements  cover  design,  construction,  material,  testing,  commissioning,  reservoir  monitoring  and 
recordkeeping  for  existing and  newly constructed  underground  natural  gas  storage  facilities  as  well  as  procedures and  practices  for 
newly  constructed  and  existing  underground  natural  gas  storage  facilities,  such  as  operations,  maintenance,  threat  identification, 
monitoring, assessment, site security, emergency response and preparedness, training, recordkeeping and reporting.  These regulations 
and any further increased attention to and requirements for underground storage safety and infrastructure by state and federal regulators 
that may result from this incident will not affect us in a way that materially differs from the way it affects other natural gas producers. 

Environmental Regulations 

General.  Our oil and gas exploration, development and production operations are subject to stringent federal, state and local laws and 
regulations  governing  the  discharge  or  release  of  materials  into  the  environment  or  otherwise  relating  to  environmental  protection.  
Numerous governmental agencies, such as the U.S. Environmental Protection Agency (the “EPA”), issue regulations to implement and 
enforce such laws, which often require costly compliance measures that carry substantial penalties for noncompliance.  These laws and 
regulations may require the acquisition of a permit before drilling or facility construction commences; restrict the types, quantities and 
concentrations of various materials that can be released into the environment; limit or prohibit project siting, construction or drilling 
activities on certain lands; require remedial and closure activities to prevent pollution from former operations; and impose substantial 
liabilities for unauthorized pollution.  The EPA and analogous state agencies may delay or refuse the issuance of required permits or 
otherwise include onerous or limiting permit conditions that may have a significant adverse impact on our ability to conduct operations.   

Changes  in environmental  laws  and  regulations  occur  frequently, and any changes that  result in more  stringent and  costly material 
handling, storage, transport, disposal or cleanup requirements could materially and adversely affect our operations and financial position, 
as well as those of the oil and gas industry in general.  While we believe that we are in compliance, in all material respects, with current 
applicable environmental laws and regulations, future environmental enforcement remains a material risk due to the potential magnitude 
of exposure in the event of a noncompliance.  We have incurred in the past, and expect to incur in the future, capital costs related to 
environmental compliance.  Such expenditures are included within our overall capital budget and are not separately itemized. 

12 

The environmental laws and regulations which have the most significant impact on the oil and gas exploration and production industry 
are as follows: 

Superfund.    The  Comprehensive  Environmental  Response,  Compensation  and  Liability  Act  of  1980,  as  amended  (“CERCLA”  or 
“Superfund”), and comparable state laws impose strict joint and several liability for sites contaminated by certain hazardous substances 
on classes of potentially responsible persons.  These persons include the owner or operator of the site where a release occurred and 
anyone who disposed of or arranged for the disposal of the hazardous substance released at the site.  Under CERCLA, such persons may 
be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, 
for  damages  to  natural  resources and  for  the costs  of  certain  health  studies.    In  the course  of  our  ordinary  operations, we  may  use, 
generate or handle material that may be regulated as “hazardous substances.”  Consequently, we may be jointly and severally liable 
under  CERCLA  or  comparable  state  statutes  for  all  or  part  of  the  costs  required  to  clean  up  sites  where  these  materials  have  been 
disposed or released. 

We currently own or lease, and in the past have owned or leased, properties that for many years have been used for the exploration and 
production  of  oil  and  gas.    Although  we  have  used  operating  and  disposal  practices  that  were  standard  in  the  industry  at  the  time, 
hazardous substances, wastes or hydrocarbons may have been released on, under or from the properties owned or leased by us or on, 
under or from other locations where such substances have been taken for recycling or disposal.  In addition, many of these owned and 
leased properties have been previously owned or operated by third parties whose treatment and disposal of hazardous substances, wastes 
or hydrocarbons were not under our control and not known to us.  Similarly, the disposal facilities where discarded materials are sent 
are also often operated by third parties whose waste treatment and disposal practices are similarly not under our control.  While we only 
use what we consider to be reputable disposal facilities, we might not know of a potential problem if the problem itself is not discovered 
until years  later.    Current  and  formerly  owned  or  operated  properties,  adjacent  affected  properties,  offsite  disposal  facilities  and 
substances disposed or released on them may be subject to CERCLA and analogous state laws.  Under these laws, we could be required: 

• 

• 

• 

• 

• 

to investigate the source and extent of impacts from released hazardous substances; 

to remove or remediate previously disposed materials, including materials disposed or released by prior owners or operators or 
other third parties; 

to clean up and remediate contaminated property, including both soils and contaminated groundwater; 

to perform remedial operations to prevent future contamination, including the plugging and abandonment of wells drilled and left 
inactive by prior owners and operators; or 

to pay some or all of the costs of any such action. 

At this time, we do not believe that we are a potentially responsible party with respect to any Superfund site and we have not been 
notified of any claim, liability or damages under CERCLA or any state analog. 

Oil Pollution Act.  The Oil Pollution Act of 1990 (“OPA”) and regulations issued under OPA impose strict, joint and several liability 
on “responsible parties” for removal costs and damages resulting from oil spills into or upon navigable waters, adjoining shorelines or 
in the exclusive economic zone of the United States.  A “responsible party” includes the owner or operator of an onshore facility and 
the lessee, permittee or holder of a right of use and easement of the area in which an offshore facility is located.  OPA establishes a 
liability limit for onshore facilities of $350 million per spill, while the liability limit for offshore facilities is the payment of all removal 
costs plus $75 million per spill damages.  These limits do not apply if the spill is caused by a responsible party’s gross negligence or 
willful misconduct; the  spill  resulted  from  a  responsible  party’s  violation  of  a federal  safety,  construction  or  operating  regulation;  a 
responsible party fails to report a spill or to cooperate fully in a cleanup; or a responsible party fails to comply with an  order issued 
under the authority  of the Intervention  on the  High  Seas  Act.   OPA  requires the lessee  or  permittee  of the offshore  area  in  which  a 
covered offshore facility is located to establish and maintain evidence of financial responsibility in the amount of $35 million to cover 
liabilities related  to  an  oil  spill  for  which  such  responsible party  is  statutorily  responsible.   The  President  of  the  United  States  may 
increase the amount of financial responsibility required under OPA by up to $150 million, depending on the risk represented by the 
quantity or quality of oil that is handled by the facility.  Any failure to comply with OPA’s requirements or inadequate cooperation 
during a spill response action may subject a responsible party to administrative penalties.  We believe we are in compliance with all 
applicable OPA financial responsibility obligations.  Moreover, we are not aware of any action or event that would subject us to liability 
under OPA.

Resource  Conservation  and  Recovery Act.   The Resource Conservation and  Recovery  Act  (“RCRA”)  and  comparable  state  statutes 
regulate  the  generation, transportation, treatment,  storage,  disposal and  cleanup  of  hazardous and  non-hazardous  wastes.   Under  the 
auspices of the EPA, the individual states administer some or all of the provisions of RCRA, sometimes in conjunction with their own 
more stringent requirements.  Additionally, various federal, state and local agencies have jurisdiction over transportation, storage and 
disposal of hazardous waste and seek to regulate movement of hazardous waste in ways not preempted by federal law.  We generate 
solid and hazardous wastes that are subject to RCRA and comparable state laws.  Drilling fluid, produced water and many other wastes 
associated with the exploration, development and production of crude oil or natural gas are currently exempt from RCRA’s hazardous 
waste  provisions.   However,  it  is  possible  that certain oil and  natural  gas exploration  and production  wastes  now  classified as  non-
hazardous  could  be  regulated as  hazardous  waste  in  the  future.   In  September 2010, the  Natural  Resources  Defense  Council filed  a 
petition with the EPA, requesting it to reconsider the RCRA hazardous waste exemption for exploration, production and development 
wastes.    In  December 2016,  the  court  entered  a  Consent  Decree  resolving  the  litigation,  under  which  the  EPA  would  issue  such  a 
rulemaking  or  make  a  determination  that  it  was  not  necessary  by  March  15,  2019.    In  response,  in  April  2019,  the  EPA  issued  a 
determination that rulemaking to address waste from oil and gas exploration and production operations was not necessary at this time.  
However,  it  is  possible  that  the  EPA  will  take  up  such  regulatory  changes  at  a  later  date.    Any  such  change  in  the  current  RCRA 
exemption and  comparable  state  laws could  result  in an  increase in  the  costs to  manage and  dispose  of  wastes.   Additionally, these 
exploration  and  production  wastes  will  continue  to  be regulated  by  state  agencies  as  solid  waste.    Also,  non-exempt waste  streams 
generated by us will continue to be subject to existing onerous hazardous waste regulations.  Although we do not believe the current 
costs of managing our wastes (as they are presently classified) to be significant, any repeal or modification of the oil and gas exploration 
and production exemption by administrative, legislative or judicial process, or modification  of similar exemptions in analogous state 
statutes would increase the volume of hazardous waste we are required to manage and dispose of and would cause us, as well as our 
competitors, to incur increased operating expenses. 

Clean Water Act.  The Federal Water Pollution Control Act, or the Clean Water Act, as amended (“CWA”), and analogous state laws 
impose restrictions and strict controls with respect to the discharge of pollutants, including spills and leaks of oil and other substances, 
into state waters or other waters of the United States.  The discharge of pollutants into regulated waters is prohibited, except in accordance 
with the terms of a permit issued by the EPA or an analogous state agency.  Spill prevention, control and countermeasure requirements 
under federal law require appropriate containment berms and similar structures to help prevent the contamination of navigable waters 
in  the event  of a  petroleum  hydrocarbon tank  spill,  rupture  or  leak.    In  addition,  CWA and analogous  state  laws  require  individual 
permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. 

Where required, costs may be associated with the treatment of wastewater and/or the development and implementation of storm water 
pollution  prevention  plans.    Federal  and  state  regulatory  agencies  can  impose  administrative,  civil  and  criminal  penalties  for  non-
compliance with discharge permits or other requirements of CWA and analogous state laws and regulations.   

In addition, the CWA requires permits for discharges of dredged or filled materials into waters of the United States.  These permits 
(“404  Permits”)  are  under  the  joint  jurisdiction  of the EPA and  the  Army  Corps of  Engineers.   404  Permits may be  required  where 
development or construction activities have the potential to impact wetland areas that are considered waters of the United States.  In 
2015, the EPA greatly expanded the definition of waters of the United States.  In doing so, it required 404 permits for disturbances in 
areas before not considered subject to United States CWA jurisdiction.  However, effective December 23, 2019, the rule broadening the 
definition was repealed, ostensibly restoring jurisdiction to only those waterbodies (including wetlands) that have a “significant nexus” 
to navigable waters of the United States.  Further rulemaking to refine the definition of waters of the United States is expected from the 
EPA in 2020.  Any expansion of the scope of the CWA could increase costs associated with permitting and regulatory compliance.  
However, it is expected that any such change would not disparately affect us and our competitors.  

Air  Emissions.    The  Federal  Clean  Air  Act, as  amended  (the  “CAA”),  and  comparable  state laws  regulate  emissions of  various  air 
pollutants from various industrial sources through air emissions permitting programs and also impose other monitoring and reporting 
requirements.  New Source Performance Standards were promulgated for the oil and gas industry in 2012.  These standards set limits 
for sulfur dioxide and volatile organic compound emissions and required application of reduced emission completion techniques by the 
industry.  We may be required to incur certain capital expenditures in the future for air pollution control equipment in connection with 
obtaining and maintaining pre-construction and operating permits and approvals for air emissions.  In addition, the EPA has developed, 
and  continues  to  develop,  stringent  regulations  governing  emissions  of  toxic  air  pollutants  at  specified  sources.    Federal  and  state 
regulatory agencies can impose penalties for non-compliance with air permits or other requirements of the CAA and associated state 
laws and regulations. 

14 

In May 2016, the EPA issued a final rule regulating methane emissions from oil and natural gas operations (the “Subpart OOOOa Rule”).  
This rule applies to emissions from new, reconstructed and modified processes and equipment and also requires owners and operators 
to find and repair leaks to address fugitive emissions. 

Certain states have also adopted, or are considering, regulations addressing methane releases from oil and gas operations.  Colorado has 
adopted regulations reducing methane emissions from oil and gas operations.  Compliance with rules applicable to jurisdictions in which 
we operate could result in significant costs, including increased capital expenditures and operating costs, which may adversely impact 
our business.   

However, in September 2019, the EPA proposed two alternative amendments to the Subpart OOOOa Rule.  Both amendments would 
remove  all  methane-specific  requirements  from  production  and  processing  segments.    The  first  amendment  would  also  remove 
transportation  and  storage  facilities  from  the  definition  of  covered  facilities.    The  comment  period  for  the  proposed  rule  closed  on 
November 25, 2019.  The net effect of either of these amendments, if finalized, would significantly reduce compliance obligations and 
associated costs.  

Hydraulic Fracturing.  Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons 
from tight rock formations.  The process involves the injection of mainly water and sand plus a de minimis amount of chemicals under 
pressure into formations to fracture the surrounding rock and stimulate production.  We expect that we will utilize hydraulic fracturing 
for the foreseeable future to complete or recomplete wells in areas in which we work.  Hydraulic fracturing is typically regulated at the 
state level; however, the EPA issued guidance in 2014 to address hydraulic fracturing injections using diesel. 

In addition, in June 2016, the EPA issued a final rule promulgating pretreatment standards for discharges of wastewater pollutants from 
onshore unconventional oil and gas extraction facilities to publicly-owned treatment works.  The EPA, along with other federal agencies 
such as the U.S. Department of Energy, the U.S. Government Accountability Office, the U.S. Department of Interior and the White 
House Council for Environmental Quality continue to study various aspects of hydraulic fracturing.   

In addition, legislation has been introduced in Congress from time to time to provide for federal regulation of hydraulic fracturing and 
to require disclosure of the chemicals used in the fracturing process.  Multiple states, including Texas, Colorado and Wyoming have 
already  adopted  rules  requiring  disclosures  of chemicals  used  in  hydraulic  fracturing  and  others  have  enacted  regulations  imposing 
additional requirements on activities involving hydraulic fracturing.  Chemical disclosure regulations may increase compliance costs 
and may limit our ability to use cutting-edge technology in markets where disclosure is required.  Further, laws such as those restricting 
the use of or regulating the time, place and manner of hydraulic fracturing (such as setback ordinances) may impact our ability to fully 
extract reserves.  No assurance can be given as to whether or not  such measures might be adopted in the jurisdictions in which our 
properties are located.  If new laws, regulations or ordinances that significantly restrict or otherwise impact hydraulic fracturing are 
passed by Congress  or  adopted in the  states  or  local municipalities  where our properties are  located,  such  legal  requirements  could 
prohibit or make it more difficult or costly for us to perform hydraulic fracturing activities. 

Further, in May 2014, the EPA published an Advance Notice of Proposed Rulemaking under the Toxic Substances Control Act, relating 
to  the  disclosure  of chemical  substances and mixtures  used  in  oil  and  gas  exploration  and  production.    On July 11, 2014,  the EPA 
extended the public comment period for the rulemaking to September 18, 2014.  The EPA has not yet taken further action with respect 
to this rule.  Depending on the precise disclosure requirements the EPA elects to impose, if any, we may be obliged to disclose valuable 
proprietary information, and failure to do so may subject us to penalties.  In addition, we may be required to disclose information of 
third parties, that may be inaccurate or that we may be contractually prohibited from disclosing, which could also subject us to penalties. 

In addition, in July 2014, a major university and U.S. Geological Survey researchers published a study purporting to find a connection 
between the deep well injection of hydraulic fracturing wastewater and a sharp increase in seismic activity in Oklahoma since 2008.  
This study, as well as subsequent studies and reports, may trigger new legislation or regulations that would limit or ban the disposal of 
hydraulic fracturing wastewater in deep injection wells.  If such new laws or rules are adopted, our operations may be curtailed while 
alternative treatment and disposal methods are developed and approved. 

Global Warming and Climate Change.  In December 2009, the EPA published its findings that emissions of carbon dioxide, methane 
and other greenhouse gases (“GHG”) present an endangerment to public health and the environment because emissions of such gases 
are, according to the EPA, contributing to the warming of the earth’s atmosphere and other climate changes.  Based on these findings, 
the EPA has adopted and implemented regulations that restrict emissions of GHG under existing provisions of the CAA. 

15 

At present, the EPA may establish GHG permitting requirements for stationary sources already subject to the Prevention of Significant 
Deterioration (“PSD”) and Title V requirements of the CAA.  Certain of our equipment and installations may currently be subject to 
PSD and Title V requirements and hence, under the Supreme Court’s ruling, may also be subject to the installation of controls to capture 
GHGs.  For any equipment or installation so subject, we may have to incur increased compliance costs to capture related GHG emissions. 

In October 2016, the EPA proposed revisions to the rule applicable to GHGs for PSD and Title V permitting requirements.  The public 
comment period for the rulemaking concluded on December 16, 2016.  However, although the rulemaking remains on the EPA’s long-
term regulatory agenda, no final rule has been published.   

In August 2015, the EPA issued a rule to reduce carbon emissions from electric generating units.  The rule, commonly called the “Clean 
Power Plan”, required states to develop plans to reduce carbon emissions from fossil fuel-fired generating units commencing in 2022, 
with the reductions to be fully phased in by 2030.  However, in February 2016, the U.S. Supreme Court stayed the implementation of 
the Clean Power Plan while it was being challenged in court.  On October 16, 2017, the EPA published a proposed rule that would repeal 
the Clean Power Plan and on August 18, 2018, the EPA proposed the Affordable Clean Energy (“ACE”) rule as a replacement to the 
Clean Power Plan.  The EPA issued the final ACE rule in June 2019.  As expected, over 20 states and public health and environmental 
organizations have challenged the rule.  The EPA has sought expedited review in the hopes that the cases will be resolved by the summer 
of 2020.  If the ACE rule were to become final, the costs of compliance are expected to be significantly less than they would have been 
under the Clean Power Plan. 

In addition, both houses of Congress have actively considered legislation to reduce emissions of GHG, and many states have already 
taken  legal  measures  to  reduce emissions  of  GHG,  primarily through the  development  of  GHG inventories,  GHG  permitting  and/or 
regional GHG “cap and trade” programs.  Most of these “cap and trade” programs work by requiring either major sources of emissions 
or major producers of fuels to acquire and surrender emission allowances, with the number of allowances available for purchase reduced 
each year until the overall GHG emission reduction goal is achieved.  Also, in recent years, lawsuits have been brought against other 
energy companies for matters relating to climate change.  Multiple states and localities have also initiated investigations in climate-
change related matters.  While the current suits focus on a variety of issues, at their core they seek compensation for the effects of climate 
change from companies with ties to GHG emissions.  It is currently unknown what the outcome of these types of actions may be, but 
the costs of defending against such actions may be expected to rise.  Finally, it should be noted that many scientists have concluded that 
increasing  concentrations  of  GHG  in  the  atmosphere  may  produce  climate  changes  that  have  significant  physical  effects,  such  as 
increased frequency and severity of storms, droughts, floods and other climatic events.  If any such effects were to occur, they could 
have an adverse effect on our assets and operations. 

Consideration of Environmental Issues in Connection with Governmental Approvals.  Our operations frequently require licenses, permits 
and/or  other  governmental  approvals.    Several  federal  statutes,  including  the  Outer  Continental  Shelf  Lands  Act  (“OCSLA”),  the 
National Environmental Policy Act (“NEPA”) and the Coastal Zone Management Act (“CZMA”), require federal agencies to evaluate 
environmental  issues  in  connection  with  granting  such  approvals  and/or  taking  other  major  agency  actions.    OCSLA,  for  instance, 
requires  the  U.S.  Department of  Interior  to  evaluate  whether certain  proposed activities  would  cause  serious  harm  or damage to  the 
marine, coastal or human environment.  Similarly, NEPA requires the U.S. Department of Interior and other federal agencies to evaluate 
major agency actions having the potential to significantly impact the environment.  In the course of such evaluations, an agency would 
have to prepare an environmental assessment and potentially an environmental impact statement.  Recent federal court cases involving 
natural gas pipelines have involved challenges to the sufficiency of the evaluation of climate change impacts in environmental impact 
statements prepared under NEPA.  The CZMA, on the other hand, aids states in developing a coastal management program to protect 
the coastal environment from growing demands associated with various uses, including offshore oil and gas development.  In obtaining 
various approvals from the U.S. Department of Interior, we must certify that we will conduct our activities in a manner consistent with 
all applicable regulations. 

Employees 

As of January 31, 2020, we had approximately 505 full-time employees.  Our employees are not represented by any labor unions.  We 
consider our relations with our employees to be satisfactory and have never experienced a work stoppage or strike.

Item 1A.      Risk Factors 

Each of the risks described below should be carefully considered, together with all of the other information contained in this Annual 
Report on Form 10-K, before making an investment decision with respect to our securities.  In the event of the occurrence, reoccurrence, 
continuation or increased severity of any of the risks described below, our business, financial condition or results of operations could be 
materially and adversely affected, and you may lose all or part of your investment. 

Oil and natural gas prices are very volatile.  An extended period of low oil and natural gas prices may adversely affect our business, 
financial condition, results of operations or cash flows. 

The oil and gas markets are very volatile, and we cannot predict future oil and natural gas prices.  The price we receive for our oil, NGL 
and natural  gas  production heavily influences  our  revenue, profitability, access to capital  and  future rate  of growth.   The  prices  we 
receive for our production depend on numerous factors beyond our control, including, but not limited to, the following: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

changes in regional, domestic and global supply and demand for oil and natural gas; 

the level of global oil and natural gas inventories; 

the actions of the Organization of Petroleum Exporting Countries; 

the price and quantity of imports of oil and natural gas; 

market demand and capacity limitations on exports of oil and natural gas; 

political and economic conditions, including embargoes and sanctions, in oil-producing countries or affecting other oil-producing 
activity, such as the U.S. imposed sanctions on Venezuela and Iran and conflicts in the Middle East; 

developments of North American energy infrastructure; 

the level of global oil and natural gas exploration and production activity; 

the effects of global conservation and sustainability measures; 

proximity and capacity of oil and natural gas pipelines and other transportation facilities; 

the  effects  of  global  and  domestic  economy,  including  the  impact  of  expected  growth,  access  to  credit,  financial  and  other 
economic issues; 

weather conditions; 

technological advances affecting energy consumption; 

current  and  anticipated  changes  to  domestic  and  foreign  governmental  regulations,  such  as  regulation  of  oil  and  natural  gas 
gathering and transportation, including those that may arise as a result of the upcoming U.S. Presidential election; 

the price and availability of competitors’ supplies of oil and natural gas; 

basis differentials associated with market conditions, the quality and location of production and other factors; 

acts of terrorism; 

the price and availability of alternative fuels; and 

18 

• 

acts of force majeure. 

These factors and the volatility of the energy markets generally make it extremely difficult to predict future oil and natural gas price 
movements.  Also, prices for crude oil and prices for natural gas do not necessarily move in tandem.  Declines in oil or natural gas prices 
would not only reduce revenue, but could also reduce the amount of oil and natural gas that we can economically produce and therefore 
potentially lower our oil and gas reserve quantities.  If the oil and natural gas industry experiences extended periods of low prices, we 
may, among other things, be unable to meet all of our financial obligations or make planned expenditures. 

Substantial and extended declines in oil, NGL and natural gas prices have resulted and may continue to result in impairments of our 
proved oil and gas properties or undeveloped acreage and may materially and adversely affect our future business, financial condition, 
cash flows, results of operations, liquidity or ability to finance planned capital expenditures.  To the extent commodity prices received 
from production are insufficient to fund planned capital expenditures, we will be required to reduce spending, sell assets or borrow to 
fund any such shortfall.  Lower commodity prices may reduce the amount of our borrowing base under our credit agreement, which is 
determined at the discretion of our lenders based on the collateral value of our proved reserves that have been mortgaged to the lenders, 
and is subject to regular redeterminations on May 1 and November 1 of each year, as well as special redeterminations described in the 
credit agreement.  Upon a redetermination, if total outstanding credit exposure exceeds the redetermined borrowing base, we  will be 
required to prepay outstanding borrowings in an aggregate principal amount equal to such excess in six substantially equal monthly 
installments.  

Lower commodity prices may also make it more difficult for us to comply with the covenants and other restrictions in the agreements 
governing our debt as described under the risk factor entitled “The instruments governing our indebtedness contain various covenants 
limiting the discretion of our management in operating our business.” 

Alternatively, higher oil, NGL and natural gas prices may result in significant mark-to-market losses being incurred on our commodity-
based derivatives, which may in turn cause us to experience net losses. 

Drilling  for  and  producing  oil  and  natural  gas  are  high  risk  activities  with  many  uncertainties  that  could  adversely  affect  our 
business, financial condition, results of operations or cash flows. 

Our  future  success  will  depend  on  the  success  of  our  exploration,  development  and  production  activities.    Our  oil  and  natural  gas 
exploration and development activities are subject to numerous risks beyond our control, including the risk that drilling will not result 
in commercially viable oil or natural gas production.  Our decisions to purchase, explore,  develop or otherwise exploit prospects or 
properties  will depend in part  on  the evaluation  of  data  obtained through  geophysical and  geological analyses,  production  data and 
engineering studies, the results of which are often inconclusive or subject to varying interpretations.  Refer to the risk factor entitled 
“Reserve estimates depend on many assumptions that may turn out to be inaccurate...” for a discussion of the uncertainty involved in 
these processes.  Our cost of drilling, completing and operating wells is often uncertain before drilling commences.  Overruns in budgeted 
expenditures are common risks that can make a particular project uneconomical.  Further, many factors may curtail, delay or cancel 
drilling, including, but not limited to, the following: 

• 

• 

• 

• 

• 

• 

• 

substantial or extended declines in oil, NGL and natural gas prices; 

delays imposed by or resulting from compliance with regulatory requirements; 

delays in or limits on the issuance of drilling permits by state agencies or on our federal leases, including as a result of government 
shutdowns; 

pressure or irregularities in geological formations; 

pipeline takeaway and refining and processing capacity; 

shortages of or delays in obtaining qualified personnel or equipment, including drilling rigs and completion services; 

equipment failures or accidents; 

19 

• 

• 

adverse weather events, such as floods, blizzards, ice storms, tornadoes and freezing temperatures; and 

title defects. 

Our debt level and the covenants in the agreements governing our debt could negatively impact our financial condition, results of 
operations, cash flows and business prospects. 

As  of  December 31,  2019,  we  had outstanding  $262  million  of  1.25%  Convertible  Senior  Notes  due  April  2020 and  $2.2  billion  of 
senior notes, which consisted of $774 million of 5.75% Senior Notes due March 2021, $408 million of 6.25% Senior Notes due April 
2023 and $1,000 million of 6.625% Senior Notes due January 2026.  We had $375 million of borrowings and $2 million in letters of 
credit  outstanding  under  Whiting  Oil  and  Gas  Corporation’s  (“Whiting  Oil  and  Gas”)  credit  facility  with  $1.4  billion  of  available 
borrowing capacity.  The credit agreement matures on April 12, 2023, provided that if at any time and for so long as any senior notes 
(other than the 1.25% Convertible Senior Notes due April 2020) have a maturity date prior to 91 days after April 12, 2023, the maturity 
date shall be the date that is 91 days prior to the maturity of such senior notes.  We are allowed to incur additional indebtedness, provided 
that we meet certain requirements in the indentures governing our senior notes and Whiting Oil and Gas’ credit agreement. 

Our level of indebtedness and the covenants contained in the agreements governing our debt could have important consequences for our 
operations, including, but not limited to: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

making  it  more  difficult  for  us to  satisfy  our  obligations  with  respect  to  our indebtedness,  and  any  failure  to comply  with  the 
obligations of any of our debt agreements, including financial and other restrictive covenants, could result in an event of default 
under Whiting Oil and Gas’ credit agreement and the indentures governing our senior notes and convertible senior notes; 

requiring us to dedicate a substantial portion of our cash flow from operations to required payments on debt, thereby reducing the 
availability of cash flow for working capital, capital expenditures and other general business activities; 

limiting our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions and general 
corporate and other activities; 

increasing the possibility that we may be unable to generate sufficient cash to pay, when due, the principal of, interest on or other 
amounts due or otherwise refinance our indebtedness; 

limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; 

placing us at a competitive disadvantage relative to other less leveraged competitors; 

making us vulnerable to increases in interest rates, because debt under Whiting Oil and Gas’ credit agreement is subject to certain 
rate variability; 

making  us  more  vulnerable  to  economic  downturns  and  adverse  developments  in  our  industry  or  the  economy  in  general, 
especially declines in oil and natural gas prices; and 

reducing our borrowing base when oil and natural gas prices decline and our ability to maintain compliance with our financial 
covenants becomes more difficult, which may reduce or eliminate our ability to fund our operations. 

We may be required to repay all or a portion of our debt on an accelerated basis in certain circumstances.  If we fail to comply with the 
covenants and other restrictions in the agreements governing our debt, it could lead to an event of default and the acceleration of our 
repayment of outstanding debt.  Refer to the risk factor entitled “The instruments governing our indebtedness contain various covenants 
limiting the discretion of our management in operating our business.”  

If we are unable to generate enough cash flow from operations to service our indebtedness or are unable to use future borrowings 
to refinance our indebtedness or fund other capital needs, we may have to undertake alternative financing plans, which may have 
onerous terms or may be unavailable.

Our earnings and cash flow could vary significantly from year to year due to the volatility of oil and natural gas prices.  As a result, the 
amount of debt that we can manage in some periods may not be appropriate for us in other periods.  Additionally, our future cash flow 
may be insufficient to meet our debt obligations and commitments.  A range of economic, competitive, business and industry factors 
will affect  our  future  financial  performance  and,  as a  result, our  ability to  generate  cash  flow  from  operations and  service  our  debt.  
Factors that may cause us to generate cash flow that is insufficient to meet our debt obligations include the events and risks related to 
our business, many of which are beyond our control.  Any cash flow insufficiency would have a material adverse impact on our business, 
financial condition, results of operations, cash flows and liquidity and our ability to repay or refinance our debt.  If we do not generate 
sufficient cash flow from operations to service our outstanding indebtedness, or if future borrowings are not available to us in an amount 
sufficient to enable us to pay or refinance our indebtedness, we may be required to undertake various alternative financing plans, which 
may include: 

• 

• 

• 

• 

• 

refinancing or restructuring all or a portion of our debt;  

seeking alternative financing or additional capital investment;  

selling strategic assets; 

reducing or delaying capital investments; or  

revising or delaying our strategic plans. 

We cannot assure you that we would be able to implement any of the above alternative financing plans, if necessary, on commercially 
reasonable terms or at all.  If we cannot make scheduled payments on our indebtedness or otherwise fail to comply with the covenants 
and other restrictions in the agreements governing our debt, we will be in default and the lenders under Whiting Oil and Gas’ credit 
agreement and the holders of our senior notes and convertible senior notes could declare all outstanding principal and interest to be due 
and payable.  Additionally, the lenders under Whiting Oil and Gas’ credit agreement could terminate their commitments to loan money 
and could foreclose against our assets collateralizing our borrowings, and we could be forced into bankruptcy or liquidation.  If the 
amounts outstanding under any of our significant indebtedness were to be accelerated, we cannot assure you that our assets would be 
sufficient to repay in full the amounts owed to the lenders or to our other debt holders.  Our inability to generate sufficient cash flows 
to  satisfy  our  debt  obligations,  or  to  refinance  our  indebtedness  on  commercially  reasonable  terms  or  at  all,  would  materially  and 
adversely affect our business, financial position, results of operations and cash flows. 

A negative shift in investor sentiment of the oil and gas industry could adversely affect our ability to raise debt and equity capital. 

Certain segments of the investor community have developed negative sentiment towards investing in our industry.  Recent equity returns 
in the sector versus other industry sectors have led to lower oil and gas representation in certain key equity market indices.  In addition, 
some investors, including investment advisors and certain sovereign wealth funds, pension funds, university endowments and family 
foundations, have stated policies to disinvest in the oil and gas sector based on their social and environmental considerations.  Certain 
other  stakeholders  have  also  pressured  commercial  and  investment  banks  to  stop  financing  oil  and  gas  production  and  related 
infrastructure projects. 

Such developments, including environmental activism and initiatives aimed at limiting climate change and reducing air pollution, could 
result in downward pressure on the stock prices of oil and gas companies, including ours. This may also potentially result in a reduction 
of available capital funding for potential development projects, impacting our future financial results.  Refer to the Risk Factor entitled 
“Negative public perception regarding us and/or our industry could have an adverse effect on our operations.” 

The instruments governing our indebtedness contain various covenants limiting the discretion of our management in operating our 
business. 

The  indentures  governing  our  senior  notes  and convertible senior  notes  and Whiting  Oil  and  Gas’ credit agreement contain various 
restrictive covenants that may limit our management’s discretion in certain respects.  In particular, these agreements limit our and our 
subsidiaries’ ability to, among other things: 

• 

prepay, redeem or repurchase certain debt; 

21 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

pay dividends or make other distributions or repurchase or redeem our capital stock; 

make loans and investments; 

incur or guarantee additional indebtedness or issue preferred stock; 

create certain liens; 

enter into agreements that restrict dividends or other payments from our restricted subsidiaries to us; 

sell assets; 

consolidate, merge or transfer all or substantially all of our assets and those of our restricted subsidiaries taken as a whole; 

engage in transactions with affiliates; 

enter into hedging contracts; and 

create unrestricted subsidiaries. 

In addition, Whiting Oil and Gas’ credit agreement requires us, as of the last day of any quarter, to maintain the following ratios (as 
defined in the credit agreement): (i) a consolidated current assets to consolidated current liabilities ratio (which includes an add back of 
the  available  borrowing  capacity  under  the  credit  agreement)  of  not  less  than  1.0  to  1.0  and  (ii)  a  total  debt  to  last  four  quarters’ 
EBITDAX ratio of not greater than 4.0 to 1.0.  If we were in violation of these covenants, then we may not be able to incur additional 
indebtedness, including under Whiting Oil and Gas’ credit agreement.  Also, the indentures under which we issued our senior notes 
restrict us from incurring additional indebtedness and making certain restricted payments, subject to certain exceptions, unless our fixed 
charge coverage ratio (as defined in the indentures) is at least 2.0 to 1.0.  Factors that may adversely affect our ability to comply with 
these covenants include oil or natural gas price declines, lack of liquidity in property and capital markets and our inability to execute on 
our business plan. 

If we fail to comply with the restrictions in the indentures governing our senior notes and convertible senior notes, Whiting Oil and Gas’ 
credit agreement or any other subsequent financing agreements, a default may allow the creditors to accelerate the related indebtedness 
as well as any other indebtedness to which a cross-acceleration or cross-default provision applies.  In addition, lenders may be able to 
terminate any commitments they had made to make further funds available to us.  Furthermore, if we were unable to repay the amounts 
due and payable under Whiting Oil and Gas’ credit agreement, those lenders could proceed against the collateral granted to them to 
secure that indebtedness.  In the event that our lenders or noteholders accelerate the repayment of our borrowings, we and our subsidiaries 
may not have sufficient assets or be able to borrow sufficient funds to repay or refinance that indebtedness.  Also, if we are in default 
under the agreements governing our indebtedness, we will not be able to pay dividends on our capital stock. 

Moreover, the borrowing base limitation on Whiting Oil and Gas’ credit agreement is redetermined on May 1 and November 1 of each 
year, and may be the subject of special redeterminations described in such credit agreement based on an evaluation of our oil and gas 
reserves.  Because oil and gas prices are principal inputs into the valuation of our reserves, if oil and gas prices decline, our borrowing 
base could be reduced at the next redetermination date or during future redeterminations.  Upon a redetermination, if total outstanding 
credit exposure exceeds the redetermined borrowing base, we will be required to prepay outstanding borrowings in an aggregate principal 
amount equal to such excess in six substantially equal monthly installments.  We may not have sufficient funds to make such repayments. 

Strategic determinations, including the allocation of capital and other resources to strategic opportunities, are challenging, and a 
failure to appropriately allocate capital and resources among our strategic opportunities may adversely affect our business, financial 
condition, results of operations or cash flows.  

Our future growth prospects are dependent upon our ability to identify optimal strategies for investing our capital resources to produce 
rates of return.  In developing our business plan, we consider allocating capital and other resources to various aspects of our business 
including well development (primarily drilling), reserve acquisitions, exploratory activity, corporate items and other alternatives.  We 
also consider our likely sources of capital, including cash generated from operations and borrowings under Whiting Oil and Gas’ credit 

22 

agreement.  Notwithstanding the determinations made in the development of our business plan, business opportunities not previously 
identified periodically come to our attention, including possible acquisitions and dispositions.  If we fail to identify optimal business 
strategies or fail to optimize our capital investment and capital raising opportunities and the use of our other resources in furtherance of 
our business strategies, our financial condition and future growth may be adversely affected.  Moreover, economic or other circumstances 
may change from those contemplated by our business plan and our failure to recognize or respond to those changes may limit our ability 
to achieve our objectives. 

 A large  portion  of  our  producing  properties  are concentrated  in  the  Williston  Basin  of  North  Dakota  and  Montana, making  us 
vulnerable to risks associated with operating in one major geographic area. 

A large portion of our producing properties are geographically concentrated in the Williston Basin of North Dakota and Montana.  At 
December 31,  2019,  approximately  93%  of  our  total  estimated  proved  reserves  were  attributable  to  properties  located  in  this  area.  
Because of this concentration in a limited geographic area, the success and profitability of our operations may be disproportionately 
exposed to regional factors compared to competitors having more geographically dispersed operations.  These factors include,  among 
others:  (i) the  prices  of crude  oil  and  natural gas produced  from  wells  in  the region and  other regional  supply  and  demand  factors, 
including gathering, pipeline and rail transportation capacity constraints, (ii) the availability of rigs, equipment, oilfield services, supplies 
and labor, (iii) the availability of processing and refining facilities and (iv) infrastructure capacity.  In addition, our operations in the 
Williston  Basin  may  be  adversely  affected  by  severe  weather  events  such  as  floods,  blizzards,  ice  storms,  tornadoes  and  freezing 
temperatures which can intensify competition for the items and services described above and may result in periodic shortages.  The 
concentration of our operations in a limited geographic area also increases our exposure to changes in local laws and regulations, certain 
lease stipulations designed to protect wildlife and unexpected events that may occur in the regions such as natural disasters, seismic 
events (which may result in third-party lawsuits), industrial accidents, labor difficulties, civil disturbances, public protests or terrorist 
attacks.  Any one of these events has the potential to cause producing wells to be shut-in, delay operations, decrease cash flows, increase 
operating and capital costs and prevent development of lease inventory before expiration.  Any of the risks described above could have 
a material adverse effect on our business, financial condition, results of operations and cash flows.   

If  oil,  NGL  and  natural  gas  prices  decrease,  we  may  be  required  to  take  write-downs  of  the  carrying  values  of  our  oil  and  gas 
properties. 

Accounting rules require that we periodically review the carrying value of our producing oil and gas properties for possible impairment.  
Based on specific market factors and circumstances at the time of prospective impairment reviews (which may include depressed oil, 
NGL and natural gas prices and the continuing evaluation of development plans, production data, economics, possible asset sales and 
other  factors)  we  may  be  required  to  write  down  the  carrying  value  of  our  oil  and  gas  properties.    For  example,  we  recorded  an 
$835 million impairment charge during 2017 for the partial write-down of the Redtail field in Colorado.  A write-down constitutes a 
non-cash charge to earnings.  We may incur additional impairment charges in the future, which could have a material adverse effect on 
our business, financial condition, results of operations or cash flows in the period recognized. 

We may continue to incur cash and noncash charges that would negatively impact our future results of operations and liquidity.  

While executing our strategic priorities to reduce financial leverage and complexity and to lower our capital expenditures in the face of 
lower  commodity  prices,  we  have incurred certain  cash  charges.   As  we  continue  to  focus  on  our  strategic  priorities, we may incur 
additional cash and noncash charges in the future.  If incurred, these charges could have a material adverse effect on  our liquidity and 
results of operations in the period recognized. 

Federal,  state  and  local legislative  and  regulatory  initiatives  relating  to  hydraulic  fracturing  could  result  in increased  costs  and 
additional operating restrictions or delays. 

Hydraulic  fracturing  is  an  important  and  common  practice  that  is  used  to  stimulate  production  of  hydrocarbons  from  tight  rock 
formations.  The process involves the injection of mainly water and sand plus a de minimis amount of chemicals under pressure into 
formations  to  fracture  the  surrounding  rock  and  stimulate  production.    We  expect  that  we  will  utilize  hydraulic  fracturing  for  the 
foreseeable future to complete or recomplete wells in the areas in which we work.  Hydraulic fracturing is typically regulated at the state 
level,  however,  the  U.S.  Environmental  Protection  Agency  (the  “EPA”)  issued  guidance  in  2014  to  address  hydraulic  fracturing 
injections involving diesel.  In addition, in June 2016, the EPA issued a final rule promulgating pretreatment standards for discharges 
of wastewater pollutants from onshore unconventional oil and gas extraction facilities to publicly-owned treatment works.  The EPA, 

23 

along  with  other  federal  agencies  such  as  the  U.S.  Department  of  Energy,  the  U.S.  Government  Accountability  Office,  the  U.S. 
Department of Interior and the White House Council for Environmental Quality continue to study various aspects of hydraulic fracturing.  

In addition, legislation has been introduced in Congress from time to time to provide for federal regulation of hydraulic fracturing and 
to require disclosure of the chemicals used in the fracturing process.  Multiple states, including Texas, Colorado and Wyoming have 
already  adopted  rules  requiring  disclosures  of chemicals  used  in  hydraulic  fracturing  and  others  have  enacted  regulations  imposing 
additional requirements on activities involving hydraulic fracturing.  Chemical disclosure regulations may increase compliance costs 
and may limit our ability to use cutting-edge technology in markets where disclosure is required.  Further, laws such as those restricting 
the use of or regulating the time, place and manner of drilling or hydraulic fracturing (such as setback ordinances) may impact our ability 
to fully extract reserves.  No assurance can be given as to whether or not  such measures might be considered or implemented in the 
jurisdictions in which our properties are located.  If new laws, regulations or ordinances that significantly restrict or otherwise impact 
hydraulic fracturing are passed by Congress or adopted in the states or local municipalities where our properties are located, such legal 
requirements could prohibit or make it more difficult or costly for us to perform hydraulic fracturing activities. 

Further, in May 2014, the EPA published an Advance Notice of Proposed Rulemaking under the Toxic Substances Control Act, relating 
to  the  disclosure  of chemical  substances and mixtures  used  in  oil  and  gas  exploration  and  production.    On July 11, 2014,  the EPA 
extended the public comment period for the rulemaking to September 18, 2014.  The EPA has not yet taken further action with respect 
to this rule.  Depending on the precise disclosure requirements the EPA elects to impose, if any, we may be obliged to disclose valuable 
proprietary information, and failure to do so may subject us to penalties.  In addition, we may be required to disclose information of 
third parties, which may be inaccurate or which we may be contractually prohibited from disclosing, which could also subject us to 
penalties. 

In addition, in July 2014, a major university and U.S. Geological Survey researchers published a study purporting to find a connection 
between the deep well injection of hydraulic fracturing wastewater and a sharp increase in seismic activity in Oklahoma since 2008.  
This study, as well as subsequent studies and reports, may trigger new legislation or regulations that would limit or ban the disposal of 
hydraulic fracturing wastewater in deep injection wells.  If such new laws or rules are adopted, our operations may be curtailed while 
alternative treatment and disposal methods are developed and approved. 

Refer to “Hydraulic Fracturing” in Item 2 of this Annual Report on Form 10-K for more information on hydraulic fracturing. 

We have entered into physical delivery contracts and do not expect to be able to deliver all the oil required under such contracts and, 
as a result, we expect we will be required to make deficiency payments. 

As of December 31, 2019, we had three physical delivery contracts which require us to deliver fixed volumes of crude oil.  One of these 
contracts  is  tied to  oil  production at our  Sanish  field in  Mountrail  County,  North  Dakota, the  second  is  tied to  oil  production  in the 
Williston Basin and the third is tied to oil production at our Redtail field in Weld County, Colorado.  Although we believe that our 
production and reserves are sufficient to fulfill the delivery commitments at our Sanish field in North Dakota and the Williston Basin, 
if we fail to deliver the committed volumes, we would be required to pay deficiency payments of $7.00 and $5.75, respectively, per 
undelivered  barrel  (subject  to  upward  adjustment).    At  our  Redtail  field,  we  have  determined  that  it  is  not  probable  that  future  oil 
production will be sufficient to meet the minimum volume requirements under the contract in this area.  We expect to make periodic 
deficiency payments under the Redtail contract that currently total $5.24 per undelivered Bbl through the April 2020 termination date.  
During 2019,  2018 and  2017,  total  deficiency  payments  under this contract  amounted  to  $64 million,  $37 million  and  $42 million, 
respectively.  Refer to “Properties – Delivery Commitments” for more information about these delivery contracts. 

Reserve estimates  depend  on many  assumptions that  may turn  out to  be  inaccurate.   Any  material  inaccuracies  in  these  reserve 
estimates or underlying assumptions will materially affect the quantities and present value of our reserves. 

The  process  of  estimating  oil  and  natural  gas  reserves  is  complex.    It  requires  interpretations  of  available  technical  data  and  many 
assumptions, including assumptions relating to economic factors.  Any significant inaccuracies in these interpretations or assumptions 
could materially affect the estimated quantities and present value of reserves referred to in this Annual Report on Form 10-K. 

24 

In order to prepare our estimates, we must project production rates and timing of development expenditures.  We must also analyze 
available geological, geophysical, production and engineering data.  The extent, quality and reliability of this data can vary.  The process 
also requires economic assumptions about matters such as the following, among others: 

• 

• 

• 

historical production from the area compared with production rates from other producing areas; 

the assumed effect of governmental regulation; and 

assumptions about future prices of oil, NGLs and natural gas including differentials, production and development costs, gathering 
and transportation costs, severance and excise taxes, capital expenditures and availability of funds. 

Therefore, estimates of oil and natural gas reserves are inherently imprecise.  Actual future production, oil, NGL and natural gas prices, 
revenues, taxes, exploration and development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves 
will most likely vary from our estimates.  Any significant variance could materially affect the estimated quantities and present value of 
reserves referred to in this Annual Report on Form 10-K.  In addition, we may adjust estimates of proved reserves to reflect production 
history, results of exploration and development, prevailing oil and natural gas prices and other factors, many of which are beyond our 
control. 

You should not assume that the present value of future net revenues from our proved reserves, as referred to in this report, is the current 
market  value  of  our  estimated  proved  oil  and  natural  gas  reserves.    In  accordance  with  SEC  requirements,  we  base  the  estimated 
discounted future net cash flows from our proved reserves on 12-month average prices and current costs as of the date of the estimate.  
The 12-month average prices used for the year ended December 31, 2019 were $55.69 per Bbl of oil and $2.58 per MMBtu of natural 
gas.  Actual future prices and costs may differ materially from those used in the estimate.  If the 12-month average oil prices used to 
calculate our oil reserves decline by $1.00 per Bbl, then the standardized measure of discounted future net cash flows of our estimated 
proved reserves as of December 31, 2019 would have decreased by $137 million.  If the 12-month average natural gas prices used to 
calculate our natural gas reserves decline by $0.10 per MMBtu, then the standardized measure of discounted future net cash flows of 
our estimated proved reserves as of December 31, 2019 would have decreased by $41 million. 

Our exploration and development operations require substantial capital, and we may be unable to obtain needed capital or financing 
on satisfactory terms, which could lead to a loss of properties and a decline in our oil and natural gas reserves. 

The oil and gas industry is capital intensive.  We make and expect to continue to make substantial capital expenditures in our business 
and operations for the exploration, development, production and acquisition of oil and natural gas reserves.  To date, we have financed 
capital expenditures through a combination of internally generated cash flows, equity and debt issuances, bank borrowings, agreements 
with industry partners and oil and gas property divestments.  We intend to finance future capital expenditures substantially with cash 
flow from operations, cash on hand, borrowings under our credit agreement and proceeds from asset divestitures.  Our cash flow from 
operations and access to capital is subject to a number of variables, including, but not limited to: 

• 

• 

• 

• 

• 

the prices at which oil and natural gas are sold; 

our proved reserves; 

the level of oil and natural gas we are able to produce from existing wells; 

the costs of producing oil and natural gas; and 

our ability to acquire, locate and produce new reserves. 

If our revenues or the borrowing base under our credit agreement decrease as a result of lower oil and natural gas prices, operating 
difficulties, declines in reserves, or for any other reason, then we may have limited ability to obtain the capital necessary to sustain our 
operations at current levels. 

We may, from time to time, need to seek additional financing.  There can be no assurance as to the availability or terms of any additional 
financing.  Disruptions in the capital and credit markets, particularly in the energy sector, could limit our ability to access these markets 

25 

or may significantly increase our cost to borrow.  If cash generated by operations or available under our revolving credit facility is not 
sufficient to meet our capital requirements, the inability to access the cash and credit markets to obtain additional financing, on favorable 
terms or otherwise, could result in a curtailment of our operations relating to the exploration and development of our prospects, which 
in turn could lead to a possible loss of properties and a decline in our oil and natural gas reserves. 

Unless we replace our oil and natural gas reserves, our reserves and production will decline, we may not be able to sustain production. 

Unless we conduct successful exploration, development and production activities or acquire properties containing proved reserves, our 
proved reserves will decline over time.  Producing oil and natural gas reservoirs are generally characterized by declining production 
rates that vary depending upon reservoir characteristics and other factors.  Our future oil and natural gas reserves and production, and 
therefore our cash flow and income, are highly dependent on our success in efficiently developing and producing our current reserves 
and finding economically recoverable or acquiring additional economically recoverable reserves.  In pursuing acquisitions, we compete 
with other companies, many of which have greater financial and other resources to acquire attractive companies or properties.  Therefore, 
we may not be able to develop, find or acquire additional reserves to sustain or replace our current and future production, which could 
adversely affect our business, financial condition, results of operations or cash flows. 

Our  credit  rating could  negatively  impact  our  availability and  cost  of  capital  and  could  require  us  to  post more collateral  under 
certain commercial arrangements. 

Some  of  our  counterparties  have  requested  or  required  us to  post collateral  as  financial  assurance  of  our  performance under  certain 
contractual arrangements, such as gathering, transportation, processing and hedging agreements.  These collateral requirements depend, 
in part, on our credit rating.  We may be requested or required by other counterparties to post additional collateral, which may be in the 
form of additional letters of credit, cash or other acceptable collateral.  Any downgrade to our credit ratings could impact the posting of 
collateral consisting of cash or letters of credit, which would reduce availability under our credit agreement and negatively impact our 
liquidity. 

Market conditions or operational impediments may hinder our access to oil and gas markets or delay our production. 

In connection  with  our  continued  development  of  oil and  gas  properties,  we  are  exposed  to the impact  of  delays  or  interruptions  of 
production from wells on these properties, caused by transportation capacity constraints, curtailment of production or the interruption 
of  transporting  oil  and  gas  volumes  produced.    In  addition,  market  conditions  or  a  lack  of  satisfactory  oil  and  gas  transportation 
arrangements may hinder our access to oil and gas markets or delay our production.  The availability of a ready market for our oil, NGL 
and  natural  gas  production  depends  on  a  number  of  factors,  including  the  demand  for  and  supply  of  oil,  NGLs  and  natural  gas, 
downstream market conditions and competing supply alternatives.  Our ability to market our production also depends substantially on 
the availability and capacity of gathering systems, pipelines and processing facilities owned and operated by third parties and the ability 
to obtain such services on acceptable terms.  We may be disproportionately exposed to the impact of delays or interruptions of production 
caused by market constraints or the interruption of transporting oil and gas produced.  This could lead to production curtailments or 
shut-ins, and reduced revenue which could materially harm our business.  We may enter into arrangements for transportation services 
and sales to reduce curtailment risks.  However, these services expose us to the risk that third parties will default on their obligations 
under such arrangements.   

Risks  associated  with  the production,  gathering,  transportation  and  sale of  oil,  NGLs  and  natural gas could  adversely  affect  net 
income and cash flows. 

Our net income and cash flows will depend upon, among other things, oil, NGL and natural gas production and the prices received and 
costs incurred to develop and produce oil and natural gas reserves.  Drilling, production or transportation accidents that temporarily or 
permanently halt the production and sale of oil, NGLs and natural gas will decrease revenues and increase expenditures.  For example, 
accidents may occur that result in personal injuries, property damage, damage to productive formations or equipment and environmental 
damages.  Any costs incurred in connection with any such accidents that are not insured against will have the effect of reducing net 
income.  We do not have insurance policies in effect that are intended to provide coverage for losses solely related to hydraulic fracturing 
operations.  Also, our oil, NGL and natural gas production depends in large part on the proximity and capacity of pipeline systems and 
transportation facilities which are mostly owned by third parties.  The lack of availability or the lack of capacity on these systems and 
facilities could result in the curtailment of production or the delay or discontinuance of drilling plans.  Similarly, curtailments or damage 
to pipelines and other transportation facilities used to transport oil, NGL and natural gas production to markets for sale could decrease 
revenues or increase transportation expenses.  Any such curtailments or damage to the gathering systems could also require finding 

26 

alternative means to transport oil, NGL and natural gas production, which alternative means could result in additional costs that will 
have the effect of increasing transportation expenses. 

Also, accidents involving rail cars could result in significant personal injuries and property and environmental damage.  In May 2015, 
the Pipeline and Hazardous Material Safety Administration issued new rules applicable to “high-hazard flammable trains”, discussed in 
“Item 1 Business – Regulation – Regulation of Sale and Transportation of Oil” above, which could increase transportation expenses.  
Similarly, regulatory responses to the October 2015 failure at a Southern California underground natural gas storage facility could also 
lead to increased expenses for underground storage. 

In addition, drilling, production and transportation of hydrocarbons bear the inherent risk of loss of containment.  Potential consequences 
include, but are not limited to, loss of reserves, loss of production, loss of economic value associated with the affected wellbore, personal 
injuries and death, contamination of air, soil, ground water and surface water, as well as potential fines, penalties or damages associated 
with any of the foregoing consequences. 

Part of our business strategy includes selling properties which subjects us to various risks. 

Part of our business strategy includes selling properties when we believe that the sales price realized will provide an above average rate 
of return for the property or when the property no longer matches the profile of properties we desire to own.  However, there is no 
assurance that such sales will occur in the time frames or with the economic terms we expect.  Unless we conduct successful exploration, 
development and production activities or acquire properties containing proved reserves, divestitures of our properties will reduce our 
proved reserves and potentially our production.  We may not be able to develop, find or acquire additional reserves sufficient to replace 
such reserves and production from any of the properties we sell.  Additionally, agreements pursuant to which we sell properties may 
include terms that survive closing of the sale, including but not limited to indemnification provisions, which could result in us retaining 
substantial liabilities. 

Our acreage must be drilled before lease expiration, generally within three to five years, in order to hold the acreage by production.  
Failure to drill sufficient wells in order to hold acreage will result in substantial lease renewal costs, or if renewal is not feasible, 
loss of our lease and prospective drilling opportunities. 

Unless production is established on our undeveloped acreage, the underlying leases will expire.  As of December 31, 2019, the portion 
of  our  net  undeveloped  acreage that  is  subject  to  expiration  over  the  next  three  years,  if  not  successfully  developed  or  renewed,  is 
approximately 18% in 2020, 13% in 2021 and 15% in 2022.  The cost to renew such leases may increase significantly, and we may not 
be able to renew such leases on commercially reasonable terms or at all.  In addition, on certain portions of our acreage, third-party 
leases become immediately effective if our leases expire.  As such, our actual drilling activities may materially differ from our current 
expectations, which could adversely affect our business, financial condition, results of operations or cash flows. 

The unavailability or cost of additional drilling rigs, equipment, supplies, personnel and oil field services could adversely affect our 
ability to execute our exploration and development plans on a timely basis or within our budget. 

The demand for qualified and experienced field personnel to conduct field operations, geologists, geophysicists, engineers and other 
professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with oil and natural gas prices, causing 
periodic shortages.  Historically, there have been shortages of drilling rigs, completion crews and other oilfield equipment as demand 
for these items has increased along with the number of wells being drilled and completed.  These factors also cause significant increases 
in costs for equipment, services and personnel.  Higher oil and natural gas prices generally stimulate demand and result in increased 
prices  for  drilling  rigs  and  other  oilfield  goods  and  services.    Shortages  of  field  personnel  and  other  professionals,  drilling  rigs, 
completion crews, equipment or supplies or price increases could delay or adversely affect our exploration and development operations, 
which could restrict such operations or have a material adverse effect on our business, financial condition, results of operations or cash 
flows. 

Our identified drilling locations are scheduled out over several years, making them susceptible to uncertainties that could materially 
alter the occurrence or timing of their drilling. 

We have specifically identified and scheduled drilling locations as an estimation of our future multi-year drilling activities on our existing 
acreage.  These scheduled drilling locations represent a significant part of our growth strategy.  Our ability to drill and develop these 
locations depends on a number of uncertainties, including oil and natural gas prices, the availability of capital, costs of oil field goods 

27 

and  services,  drilling  results,  our ability to  extend  drilling acreage  leases  beyond expiration,  regulatory approvals  and other  factors.  
Because of these uncertainties, we do not know if the numerous potential drilling locations we have identified will ever be drilled or if 
we will be able to produce oil or gas from these or any other potential drilling locations.  As such, our actual drilling activities may 
materially  differ  from  those  presently  identified,  which  could  in  turn  adversely  affect  our  business,  financial  condition,  results  of 
operations or cash flows or require us to remove certain proved undeveloped reserves from our proved reserve base if we are unable to 
drill those PUD locations within the SEC’s 5-year window. 

Weaker price differentials and/or weaker benchmark prices of oil and natural gas and the wellhead price we receive could have a 
material adverse effect on our business, financial condition, results of operations or cash flows. 

The  prices  that  we  receive  for our oil and natural gas production generally  trade at  a  discount,  but  sometimes  at a  premium,  to the 
relevant benchmark prices such as NYMEX.  A negative or positive difference between the benchmark price and the price received is 
called a differential.  The differential may vary significantly due to market conditions, the quality and location of production and other 
risk  factors,  as  demonstrated  in  the  fourth  quarter  of 2018 when  our oil differentials  weakened  substantially.  We cannot  accurately 
predict oil and natural gas differentials.  Changes in the differential and decreases in the benchmark price for oil and natural gas could 
have a material adverse effect on our business, financial condition, results of operations or cash flows. 

Properties that we acquire may not produce as projected, and we may be unable to identify liabilities associated with the properties 
or obtain indemnities from sellers for liabilities they may have created. 

Our  business  strategy  includes  a  continuing  acquisition  program.    From  2010  through  2019,  we  completed  7  separate  significant 
acquisitions of producing properties with a combined purchase price of $4.6 billion for estimated proved reserves as of the effective 
dates of the acquisitions of 240.2 MMBOE.  The successful acquisition of producing properties requires assessment of many factors, 
which are inherently inexact and may be inaccurate, including, but not limited to, the following: 

• 

• 

• 

• 

• 

• 

• 

the anticipated levels of recoverable reserves, earnings or cash flow; 

future oil and natural gas prices; 

estimates of operating costs; 

estimates of future development costs; 

timing of future development costs; 

estimates of the costs and timing of plugging and abandonment; and 

the  assumption  of  unknown  potential  environmental  and  other  liabilities,  losses  or  costs,  including  for  example,  title  defects, 
historical spills or releases for which we are not indemnified or for which our indemnity is inadequate. 

Furthermore, acquisitions pose substantial risks to our business, financial condition, results of operations and cash flows.  The risks 
associated with acquisitions, either completed or future acquisitions, include, but are not limited to: 

• 

• 

• 

we may be unable to integrate acquired businesses successfully and to realize anticipated economic, operational and other benefits 
in a timely manner, which could result in substantial costs and delays or other operational, technical or financial problems; 

acquisitions could disrupt our ongoing business, distract management, divert resources and make it difficult to maintain our current 
business standards, controls and procedures; and 

we may issue additional equity or debt securities in order to fund future acquisitions. 

Our assessment will not reveal all existing or potential problems, nor will it permit us to become familiar enough with the properties to 
assess fully their capabilities and deficiencies.  In the course of our due diligence, we may not inspect every well, platform, facility or 
pipeline.  Inspections may not reveal structural and environmental problems, such as pipeline corrosion or groundwater contamination, 

28 

when they are made.  We may not be able to obtain contractual indemnities from the seller for liabilities that it created.  We may be 
required to  assume the  risk  of  the  physical condition  of the  properties in  addition to  the  risk  that the  properties  may  not  perform in 
accordance with our expectations. 

Our  use  of  oil  and  natural  gas  price  hedging  contracts  involves  only  a  portion  of  our  anticipated  production,  may  limit  higher 
revenues in the future in connection with commodity price increases and may result in significant fluctuations in our net income. 

We enter into hedging transactions of our oil and natural gas production revenues to reduce our exposure to fluctuations in the price of 
oil and natural gas.  Our hedging transactions to date have consisted of financially settled crude oil and natural gas options contracts, 
primarily costless collars and swaps, placed with major financial institutions.  As of February 20, 2020, we had contracts covering the 
sale of 31 MMBbl of oil per day for the remainder of 2020 and 6 MMBbl of oil per day for all of 2021.  All of our oil hedges will expire 
by December 2021.  Refer to “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A and the “Derivative Financial 
Instruments” footnote of the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for pricing information 
and a more detailed discussion of our hedging transactions. 

We may in the future enter into these and other types of hedging arrangements to reduce our exposure to fluctuations in the market 
prices of oil and natural gas, or alternatively, we may decide to unwind or restructure the hedging arrangements we previously entered 
into.  Hedging transactions expose us to risk of financial loss in some circumstances, including if production is less than expected, the 
other party to the contract defaults on its obligations or there is a change in the expected differential between the underlying price in the 
hedging agreement and actual prices received.  Hedging transactions may limit the benefit we may otherwise receive from increases in 
the price for oil and natural gas.  Our three-way collars only provide partial protection against declines in market prices due to the fact 
that when the market price falls below the sub-floor, the minimum price we will receive will be NYMEX plus the difference between 
the floor and sub-floor.  Furthermore, if we do not engage in hedging transactions or unwind hedging transactions we previously entered 
into, then we may be more adversely affected by declines in oil and natural gas prices than our competitors who engage in hedging 
transactions.  Additionally, hedging transactions may expose us to cash margin requirements. 

We recognize all gains and losses from changes in commodity derivative fair values immediately in earnings rather than deferring any 
such amounts in accumulated other comprehensive income (loss).  Consequently, we may experience significant net losses, on a non-
cash basis, due to changes in the value of our hedges as a result of commodity price volatility. 

Seasonal  weather  conditions  and lease  stipulations  adversely  affect  our  ability  to  conduct  drilling activities  in  some  of  the  areas 
where we operate. 

Oil and gas operations in the Rocky Mountains are adversely affected by seasonal weather conditions and lease stipulations designed to 
protect various wildlife.  In certain areas, drilling and other oil and gas activities can only be conducted during certain months.  This 
limits  our  ability  to  operate  in  those  areas  and  can  intensify  competition  during  those months  for  drilling  rigs,  oil  field  equipment, 
services, supplies and qualified personnel, which may lead to periodic shortages.  Resulting shortages or high costs could delay our 
operations, cause temporary declines in our oil and gas production and materially increase our operating and capital costs. 

We may incur substantial losses and be subject to substantial liability claims as a result of our oil and gas operations. 

We are not insured against all risks.  Losses and liabilities arising from uninsured and underinsured events could materially and adversely 
affect our business, financial condition, results of operations or cash flows.  Our oil and natural gas exploration and production activities 
are subject to all of the operating risks associated with drilling for and producing oil and natural gas, including, but not limited to, the 
possibility of: 

• 

• 

• 

• 

environmental hazards, such as uncontrollable flows of oil, gas, brine, well fluids, toxic gas or other pollution into the environment, 
including groundwater and shoreline contamination; 

abnormally pressured formations; 

mechanical difficulties, such as stuck oil field drilling and service tools and casing collapse; 

the loss of well control; 

29 

• 

• 

• 

• 

fires and explosions; 

personal injuries and death;  

terrorist attacks; and 

natural disasters. 

Any of these risks could adversely affect our ability to conduct operations or result in substantial losses to our company.  We may elect 
not to obtain insurance if we believe that the cost of available insurance is excessive relative to the risks presented.  In addition, pollution 
and environmental risks generally are not fully insurable.  If a significant accident or other event occurs and is not fully covered by 
insurance, then it could adversely affect us. 

We have limited control over activities on properties we do not operate, which could reduce our production and revenues and increase 
capital expenditures. 

We operate 88% of our net productive oil and natural gas wells, which represents 92% of our proved developed producing reserves as 
of December 31, 2019.  If we do not operate the properties in which we own an interest, we do not have control over normal operating 
procedures,  expenditures  or  future  development  of  our  properties.    The  failure  of  an  operator  of  our  wells  to  adequately  perform 
operations or an operator’s breach of the applicable agreements could reduce our production and revenues.  The success and timing of 
our  drilling  and  development activities on  properties  operated  by  others  therefore  depends  upon  a  number  of  factors  outside  of  our 
control, including the operator’s decisions with respect to the timing and amount of capital expenditures, the period of time over which 
the operator seeks to generate a return on capital expenditures, inclusion of other participants in drilling wells, and the use of technology, 
as well as the operator’s expertise and financial resources and the operator’s relative interest in the field.  Operators may also opt to 
decrease operational activities following a significant decline in, or a sustained period of low, oil or natural gas prices.  Because we do 
not have a majority interest in most wells we do not operate, we may not be in a position to remove the operator in the event of poor 
performance.  Accordingly, while we use reasonable efforts to cause the operator to act in a prudent manner, we are limited in our ability 
to do so. 

We have been an early entrant into new or emerging plays.  As a result, our drilling results in these areas are uncertain, the value 
of our undeveloped acreage may decline and we may incur impairment charges if drilling results are unsuccessful. 

Our drilling results in undeveloped acreage in new or emerging plays are more uncertain than drilling results in areas that are developed 
and producing.  Since new or emerging plays have limited or no production history, we are unable to use past drilling results in those 
areas to help predict our future drilling results.  Therefore, our cost of drilling, completing and operating wells in these areas may be 
higher than initially expected, and the value of our undeveloped acreage will decline if drilling results are unsuccessful.  Furthermore, 
if drilling results are unsuccessful, we may be required to write down the carrying value of our undeveloped acreage in new or emerging 
plays.  For example, during 2018 we recorded an $8 million non-cash charge for the impairment of undeveloped oil and gas properties 
where we have no current or future plans to drill.  We may also incur such impairment charges in the future, which could have a material 
adverse effect on our results of operations in the period taken.  Additionally, our rights to develop a portion of our undeveloped acreage 
may  expire  if  not  successfully developed  or  renewed.   Refer  to “Acreage”  in  Item 2 of this  Annual  Report  on  Form 10-K  for  more 
information relating to the expiration of our rights to develop undeveloped acreage. 

We are subject to complex laws that can affect the cost, manner or feasibility of doing business. 

Exploration,  development,  production  and  sale  of  oil  and  natural  gas  are  subject  to  extensive  federal,  state,  local  and  international 
regulation.  We may be required to make large expenditures to comply with governmental regulations.  Matters subject to regulation 
include, but are not limited to: 

• 

• 

• 

discharge permits for drilling operations; 

drilling bonds; 

reports concerning operations; 

30 

• 

• 

• 

well spacing; 

unitization and pooling of properties; and 

taxation. 

Under these laws, we could be liable for personal injuries, property damage and other damages.  Failure to comply with these laws also 
may result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties and litigation.  
Moreover, these  laws could  change  in  ways  that  could  substantially increase  our  costs.   Any  such  liabilities, penalties, suspensions, 
terminations or regulatory changes could materially and adversely affect our business, financial condition, results of operations or cash 
flows.  Strict liability or joint and several liability may be imposed under certain laws, which could cause us to become liable for the 
conduct of others or for consequences of our own actions.  For instance, an accidental release from one of our wells could subject us to 
substantial liabilities arising from environmental cleanup and restoration costs, claims made by neighboring landowners and other third 
parties for personal injury and property damage and fines or penalties for related violations of environmental laws or regulations.   

Our operations may incur substantial costs and liabilities to comply with environmental laws and regulations. 

Our oil and gas operations are subject to stringent federal, state and local laws and regulations relating to the release or  discharge of 
materials into the environment or otherwise relating to environmental protection.  These laws and regulations may require the acquisition 
of  a  permit  before  drilling  commences;  restrict  the  types,  quantities  and  concentration  of  materials  that  can  be  released  into  the 
environment; limit or prohibit drilling activities on certain lands; and impose substantial liabilities for unauthorized discharges.  Failure 
to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, incurrence of 
investigatory or remedial obligations, the imposition of injunctive relief, or certain leases could be cancelled in the event that an agency 
refuses to issue or delays the issuance of a required permit.  Under these environmental laws and regulations, we could be held strictly 
liable  for  the  removal  or  remediation  of  previous contamination  regardless  of  whether  we  were responsible  for  the  release  or if  our 
operations were standard in the industry at the time they were performed.  Private parties, including the surface owners of properties 
upon which we drill, may also have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance 
with environmental laws.  We may not be able to recover some or any of these costs from insurance.  Moreover, federal law and some 
state laws allow the government to place a lien on real property for costs incurred by the government to address contamination on the 
property. 

Changes in environmental laws and regulations occur frequently and may have a materially adverse impact on our business.  Compliance 
with  any  enacted  rules  could  result  in  significant  costs,  including  increased  capital  expenditures  and  operating  costs,  which  may 
adversely impact our business.  Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-
compliance of environmental laws and regulations. 

For  example,  in  2012,  the EPA  published  final  rules under the  Federal Clean  Air  Act  (the “CAA”)  that  subject  oil  and  natural  gas 
production, processing, transmission and storage operations to regulation under the New Source Performance Standards and National 
Emission Standards for Hazardous Air Pollutants.  With regard to production activities, these  rules require, among other things, the 
reduction of volatile organic compound emissions from certain fractured and refractured gas wells for which well completion operations 
are conducted and, in particular, requiring some of these wells to use reduced emission completions, also known as “green completions”, 
after January 1, 2015.  These regulations also establish specific new requirements regarding emissions from production-related wet seal 
and reciprocating compressors, pneumatic controllers and storage vessels. 

The  requirements  were  further  expanded  again  in  2016  when  the  implementation  of  Subpart OOOOa  applied  limits  on  methane 
emissions to oil and gas facilities and required operators to address leaks, also known as “fugitive emissions.” 

However, in September 2019, the EPA proposed two alternative amendments to the Subpart OOOOa Rule.  Both amendments remove 
all methane-specific requirements from production and processing segments.  The first amendment would also remove transportation 
and storage facilities from the definition of covered facilities.  The comment period for proposed rule closed on November 25, 2019.  
The net effect of any of these amendments, if finalized, would significantly reduce compliance obligations and associated costs.

The enactment of Senate Bill 19-181 “Protect Public Welfare Oil And Gas Operations” increased the regulatory authority of local 
governments in Colorado over the surface impacts of oil and gas development, which could have a material adverse effect on our 
business, financial condition, results of operations or cash flows. 

In Colorado, on April 16, 2019, Governor Polis signed into law the final version of Senate Bill 19-181 (“SB 181”), known as the “Protect 
Public Welfare Oil and Gas Operations” legislation.  SB 181 amends the Oil and Gas Conservation Act and other statutes to change the 
manner in which oil and gas development is regulated in Colorado and provide the opportunity for greater control to local governments.  
The amendments include changes to expand the authority of local governments relating to oil and gas development, as well as rulemaking 
requirements  involving  the Colorado  Oil and  Gas  Conservation  Commission  (“COGCC”)  and  the  Air  Quality  Control Commission 
(“AQCC”) that could include more stringent air emission limits for pollutants such as methane and volatile organic carbons and more 
rigorous permitting requirements.  In December 2019, Colorado’s AQCC adopted new rules targeting air emissions from upstream oil 
and gas operations, and depending on the results of other ongoing and upcoming rulemakings and actions by COGCC, the Colorado 
Department of Public Health and Environment and local jurisdictions, SB 181 could result in greater restrictions with respect to oil and 
gas development in Colorado, which could have a material adverse effect on our business, financial condition, results of operations or 
cash flows.  Efforts similar to SB 181 are likely to continue in the future, which, if successful, could result in dramatically reducing the 
area available for future oil and gas development or outright banning oil and gas development in certain jurisdictions. We cannot predict 
the nature or outcome of future ballot initiatives, legislative actions or other similar efforts, or the effects of implementation of these 
efforts by local governments. If we are required to cease operating in any of the areas in which we now operate as the result of bans or 
moratoria on drilling or related oilfield services activities, it could have a material effect on our business, financial condition, and results 
of operations.  

Issues surrounding climate change and greenhouse gas emissions could result in increased operating costs and reduced demand for 
oil and gas that we produce. 

In  December 2009,  the  EPA  published  its  findings  that emissions  of carbon  dioxide, methane  and  other  greenhouse  gases  (“GHG”) 
present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing 
to the warming of the earth’s atmosphere and other climate changes.  Based on these findings, the EPA has adopted and implemented 
regulations that restrict emissions of GHG under existing provisions of the CAA. 

At present, the EPA may establish GHG permitting requirements for stationary sources already subject to the Prevention of Significant 
Deterioration (“PSD”)  and Title V requirements of the CAA.  Certain of our equipment and installations may currently be subject to 
PSD and Title V requirements and hence, under the Supreme Court’s ruling, may also be subject to the installation of controls to capture 
GHGs.  For any equipment or installation so subject, we may have to incur increased compliance costs to capture related GHG emissions. 

In October 2016, the EPA proposed revisions to the rule applicable to GHGs for PSD and Title V permitting requirements.  The public 
comment period for the rulemaking concluded on December 16, 2016.  However, although the rulemaking remains on the EPA’s long-
term regulatory agenda, no final rule has been published. 

In August 2015, the EPA issued a rule to reduce carbon emissions from electric generating units.  The rule, commonly called the “Clean 
Power Plan”, requires states to develop plans to reduce carbon emissions from fossil fuel-fired generating units commencing in 2022, 
with the reductions to be fully phased in by 2030.  However, in February 2016, the U.S. Supreme Court stayed the implementation of 
the Clean Power Plan while it was being challenged in court.  On October 16, 2017, the EPA published a proposed rule that would repeal 
the Clean Power Plan and on August 18, 2018, the EPA proposed the Affordable Clean Energy (“ACE”) rule as a replacement to the 
Clean Power Plan.  The EPA issued the final ACE rule in June 2019.  As expected, over 20 states and public health and environmental 
organizations have already challenged the rule.  The EPA has sought expedited review in the hopes that the cases will be resolved by 
the summer of 2020.  

In addition, both houses of Congress have actively considered legislation to reduce emissions of GHG, and many states have already 
taken  legal  measures  to  reduce emissions  of  GHG,  primarily through the  development  of  GHG  inventories,  GHG  permitting  and/or 
regional GHG “cap and trade” programs.  Most of these “cap and trade” programs work by requiring either major sources of emissions 
or major producers of fuels to acquire and surrender emission allowances, with the number of allowances available for purchase reduced 
each year until the overall GHG emission reduction goal is achieved.   

Also, in recent years, lawsuits have been brought against other energy companies for matters relating to climate change.  Multiple states 
and localities have also initiated investigations in climate-change related matters.  While the current suits focus on a variety of issues, 

32 

at  their  core  they  seek compensation for the effects  of  climate change  from companies  with ties to  GHG  emissions.   It  is  currently 
unknown what the outcome of these types of actions may be, but the costs of defending against such actions may rise.   Finally, many 
scientists have concluded that increasing concentrations of GHG in the atmosphere may produce climate changes that have significant 
physical effects, such as increased frequency and severity of storms, droughts, floods and other climatic events.  If any such effects were 
to occur, they could have an adverse effect on our assets and operations. 

Negative public perception regarding us and/or our industry could have an adverse effect on our operations. 

Negative public perception regarding us and/or our industry resulting from, among other things, concerns raised by advocacy groups 
about hydraulic fracturing, waste disposal, oil spills, seismic activity, climate change, explosions of natural gas transmission lines and 
the development and operation of pipelines and other midstream facilities may lead to increased regulatory scrutiny, which may, in turn, 
lead to  new  state and  federal  safety  and  environmental  laws,  regulations,  guidelines and enforcement  interpretations.  Additionally, 
environmental groups, landowners, local groups and other advocates may oppose our operations through organized protests, attempts to 
block  or  sabotage  our  operations  or  those  of  our  midstream  transportation  providers,  intervene  in  regulatory  or  administrative 
proceedings involving our assets or those of our midstream transportation providers, or file lawsuits or other actions designed to prevent, 
disrupt or delay the development or operation of our assets and business or those of our midstream transportation providers.   These 
actions  may  cause  operational  delays  or  restrictions,  increased  operating  costs,  additional  regulatory  burdens  and  increased  risk  of 
litigation.  Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public 
may engage in the permitting process, including through intervention in the courts. Negative public perception could cause the permits 
we require to conduct our operations to be withheld, delayed or burdened by requirements that restrict our ability to profitably conduct 
our business. 

Recently, activists concerned about the potential effects of climate change have directed their attention towards sources of funding for 
fossil-fuel  energy  companies,  which  has  resulted  in  certain  financial  institutions,  funds  and  other  sources  of  capital  restricting  or 
eliminating their investment in energy-related activities. Ultimately, this could make it more difficult to secure funding for exploration 
and production activities. 

A low ESG or sustainability score could result in the exclusion of our common shares from consideration by certain investment 
funds and a negative perception of us by certain investors. 

Certain  organizations  that  provide  corporate  governance  and  other  corporate  risk  information  to  investors  and  shareholders  have 
developed scores and ratings to evaluate companies and investment funds based upon environmental, social and governance (“ESG”) 
or  sustainability metrics.   Currently,  there are  no universal standards  for  such  scores  or ratings,  but the importance  of sustainability 
evaluations is becoming more broadly accepted by investors and shareholders.  Many investment funds focus on positive ESG business 
practices and sustainability scores when making investments.  In addition, investors, particularly institutional investors, use these scores 
to benchmark companies against their peers and if a company is perceived as lagging, these investors may engage with companies to 
require improved ESG disclosure or performance.  Moreover, certain members of the broader investment community may consider a 
company’s sustainability score as a reputational or other factor in making an investment decision.  Consequently, a low sustainability 
score could result in exclusion of our common shares from consideration by certain investment funds, engagement by investors seeking 
to improve such scores and a negative perception of us by certain investors. 

We may be negatively impacted by litigation and legal proceedings. 

We are subject from time to time, and in the future may become subject, to litigation claims.  These claims and legal proceedings are 
typically claims that arise in the normal course of business and include, without limitation, claims relating to environmental, safety and 
health  matters,  commercial  or  contractual  disputes  with  suppliers  and  customers,  claims  regarding  ownership  of  mineral  interests, 
including from royalty owners, claims regarding acquisitions and divestitures, regulatory matters and employment and labor matters.  
We may also become subject to governmental or regulatory proceedings.  The outcome of such claims and legal proceedings cannot be 
predicted  with  certainty  and  some  may  be  disposed  of  unfavorably  to  us.    Among  other  pending  litigation  claims,  the  Company  is 
involved with litigation related to a payment arrangement with a third party which currently claims damages up to $41 million, as well 
as  court  costs  and  interest.    We  also  may  not  have  insurance  that  covers  such  claims  and  legal  proceedings.    Successful  claims  or 
litigation against us for significant amounts could have a material adverse effect on our reputation, business, financial condition, results 
of operations and cash flows.  Further, even if successful in resolving a claim or legal proceeding, such process could require the attention 
of members of our senior management, reducing the time they have available to devote to managing  our business, and require us to 
incur substantial legal expenses. 

33 

The loss of senior management or technical personnel could adversely affect us. 

To a large extent, we depend on the services of our senior management and technical personnel.  The loss of the services of our senior 
management or technical personnel, including Bradley J. Holly, Chairman, President and Chief Executive Officer; Bruce DeBoer, Chief 
Administrative Officer, General Counsel and Corporate Secretary; Charles J. Rimer, Chief Operating Officer; Correne S. Loeffler, Chief 
Financial Officer; and Timothy M. Sulser, Chief Corporate Development and Strategy Officer, could have a material adverse effect on 
our  business,  financial condition, results  of  operations  or  cash  flows.  We  do  not maintain, nor  do  we  plan  to  obtain, any insurance 
against the loss of any of these individuals. 

We expect to consider from time to time further strategic opportunities that may involve acquisitions, dispositions, investments in 
joint ventures, partnerships, and other strategic alternatives that may enhance shareholder value, any of which may result in the use 
of a significant amount of our management resources or significant costs, and we may not be able to fully realize the potential benefit 
of such transactions. 

We expect to continue to consider acquisitions, dispositions, investments in joint ventures, partnerships, and other strategic alternatives 
with the objective of maximizing shareholder value.  The Board and our management may from time to time be engaged in evaluating 
potential transactions and other strategic alternatives.  In addition, from time to time, we may engage financial advisors, enter into non-
disclosure agreements, conduct discussions, and undertake other actions that may result in one or more transactions.  Although there 
would be uncertainty that any of these activities or discussions would result in definitive agreements or the completion of any transaction, 
we may devote a significant amount of our management resources to analyzing and pursuing such a transaction, which could negatively 
impact our operations, and may impair our ability to retain and motivate key personnel.  In addition, we may incur significant costs in 
connection with seeking such transactions or other strategic alternatives regardless of whether the transaction is completed.  In the event 
that we consummate an acquisition, disposition, partnership or other or strategic alternative in the future, we cannot be certain that we 
would fully realize the potential benefit of such a transaction and cannot predict the impact that such strategic transaction might have 
on  our  operations  or  stock  price.   Any  potential  transaction  would  be  dependent upon  a  number  of  factors  that  may  be  beyond  our 
control, including, among other factors, market conditions, industry trends, regulatory limitations and the interest of third parties in us 
and our assets.  There can be no assurance that the exploration of strategic alternatives will result in any specific action or transaction.  
Further, any such strategic alternative may not ultimately lead to increased shareholder value.  We do not undertake to provide updates 
or make further comments regarding the evaluation of strategic alternatives, unless otherwise required by law. 

Substantial  acquisitions  or  other  transactions  could  require  significant external capital  and  could change  our  risk and  property 
profile. 

In order to finance acquisitions of additional producing or undeveloped properties, we may need to alter or increase our capitalization 
substantially  through  the  issuance  of  debt  or  equity  securities,  the  sale  of  production  payments  or  other  means.    These  changes  in 
capitalization  may  significantly  affect  our  risk  profile.    Additionally,  significant  acquisitions  or  other  transactions  can  change  the 
character of our operations and business.  The character of the new properties may be substantially different in operating or geological 
characteristics or geographic location  than  our  existing  properties.   Furthermore,  we may  not  be able to  obtain  external  funding  for 
additional future acquisitions or other transactions on economically acceptable terms or at all. 

Competition in the oil and gas industry and from alternative energy sources is intense, which may adversely affect our ability to 
compete. 

We  operate  in  a  highly  competitive  environment  for  acquiring  properties,  obtaining  investment  capital,  securing  oilfield  goods  and 
services, marketing oil and natural gas products and attracting and retaining qualified personnel.  Many of our competitors possess and 
employ financial, technical and personnel resources substantially greater than ours, which can be particularly important in the areas in 
which we operate.  Those companies may be able to pay more for productive oil and gas properties and exploratory prospects and to 
evaluate, bid for and purchase a greater number of properties and prospects than our resources allow.  Our ability to acquire additional 
prospects and  to  find and  develop  reserves in  the  future  will depend  on  our  ability  to  evaluate  and  select  suitable  properties  and  to 
consummate transactions in a highly competitive environment.  We may not be able to compete successfully in the future in acquiring 
prospective reserves,  developing  reserves,  marketing hydrocarbons, attracting  and  retaining  quality  personnel and  raising  additional 
capital. 

34 

We also face indirect competition from alternative energy sources, including wind, solar, nuclear and electric power.  The proliferation 
of alternative energy sources and businesses that provide such alternative energy sources may decrease the demand for oil and natural 
gas products.  Decreased demand for our products could adversely affect our business, financial condition, results of operations or cash 
flows. 

In connection with the passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act, 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 manage 
our risks related to oil and gas commodity price volatility. 

On  July 21,  2010,  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  was  enacted  into  law.    This  financial  reform 
legislation includes  provisions that  require over-the-counter  derivative  transactions  to  be executed through an  exchange  or centrally 
cleared.  In addition, the legislation provides an exemption from mandatory clearing requirements based on regulations to be developed 
by the Commodity Futures Trading Commission (the “CFTC”) and the SEC for transactions by non-financial institutions, such as us, to 
hedge or mitigate commercial risk.  At the same time, the legislation includes provisions under which the CFTC may impose collateral 
requirements  for  transactions, including those  that  are  used  to  hedge commercial  risk.    However,  during  drafting  of the  legislation, 
members of Congress adopted report language and issued a public letter stating that it was not their intention to impose margin and 
collateral  requirements  on  counterparties  that  utilize  transactions  to  hedge  commercial  risk.    Final  rules on  major  provisions  in  the 
legislation, like new margin requirements, may be established through rulemakings.  Although we cannot predict the ultimate outcome 
of these rulemakings, 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 to otherwise manage our financial risks related to volatility in oil and gas commodity 
prices. 

We depend on computer and telecommunications systems, and failures in our systems or cybersecurity attacks could have an adverse 
effect on our business, financial condition, results of operations or cash flows. 

Our  business has become  increasingly  dependent  upon digital  technologies to conduct  day-to-day operations, including  information 
systems,  infrastructure  and  cloud  applications.    We  have  entered  into  agreements  with  third  parties  for  hardware,  software, 
telecommunications  and  other  information  technology  services  in  connection  with  our  business.    In  addition,  we  have  developed 
proprietary software systems, management techniques and other information technologies incorporating software licensed from third 
parties.    We  rely  on  such  systems  to  process,  transmit  and  store  electronic  information,  including  financial  records  and  personally 
identifiable information such as contractor, investor and payroll data, and to manage or support a variety of business processes, including 
our supply chain, pipeline operations, gathering and processing operations, financial transactions, banking and numerous other processes 
and transactions.   

As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, also have 
increased in frequency.  A cyber-attack could include unauthorized access to digital systems for purposes of misappropriating assets or 
sensitive information, corrupting data, or causing operational disruption, or result in denial-of-service on websites.  It is possible that 
we could incur interruptions from cybersecurity attacks, computer viruses or malware, or that third party service providers could cause 
a breach of our data.  We believe that we have positive relations with our related vendors and maintain adequate anti-virus and malware 
software and controls over personally identifiable information and contractor data; however, any interruptions to our arrangements with 
third parties for our computing and communications infrastructure or any other interruptions to, or breaches of, our information systems 
could lead to data corruption, communication interruption, loss of sensitive or confidential information or otherwise significantly disrupt 
our business operations.   

Strategic targets, such as energy-related assets and transportation assets, may be at greater risk of future cyber-attacks than other targets.  
The various procedures, facilities, infrastructure and controls we utilize to monitor these threats and mitigate our exposure to such threats 
are costly and labor intensive.  Moreover, there can be no assurance that such measures will be sufficient to prevent security breaches 
from occurring.  We do not expect to obtain or maintain specialized insurance for possible liability or loss resulting from a cyber-attack 
on our assets that may shut down all or part of our business.  However, as cyber threats continue to evolve, we may be required to expend 
significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information 
security vulnerabilities.  State and federal cybersecurity legislation could also impose new requirements, which could increase our cost 
of doing business.   

To our knowledge we have not experienced any material losses relating to cyber-attacks; however, there can be no assurance that we 
will not suffer material losses in the future either as a result of an interruption to or a breach of our systems or those of our third party 

35 

vendors and service providers.  A cyber incident involving our information systems and related infrastructure, or that of third parties, 
could disrupt our business plans and negatively impact our operations in the following ways, among others, any of which could have an 
adverse effect on our reputation, business, financial condition, results of operations or cash flows:  

• 

• 

• 

• 

• 

• 

unauthorized disclosure of sensitive or personally identifiable information, including by cyber-attacks or other security breaches, 
could cause loss of data, give rise to remediation or other expenses, expose us to liability under federal and state laws, reduce our 
customers’  willingness  to  do  business  with  us,  disrupt  the  services  we  provide  to  customers  and  subject  us  to  litigation  and 
investigations; 

a  cyber-attack  on  a  third  party  could  result  in  supply  chain  disruptions  which  could  delay  or  halt  development  of  additional 
infrastructure, effectively delaying the start of cash flow from the project;  

a cyber-attack on downstream or midstream pipelines could prevent us from delivering product, resulting in a loss of revenues;  

a cyber-attack on a communications network or power grid could cause operational disruption resulting in a loss of revenues;  

a deliberate corruption of our financial or operational data could result in events of non-compliance which could lead to regulatory 
fines or penalties; and 

business interruptions could result in expensive remediation efforts, distraction of management, damage to our reputation, or a 
negative impact on the price of our common shares.

Summary of Oil and Gas Properties and Projects 

Northern Rocky Mountains 

Our Northern Rocky Mountains operations include  our properties in the Williston Basin of North Dakota and Montana targeting the 
Bakken and Three Forks formations and encompassing approximately 756,800 gross (476,300 net) developed and undeveloped acres as 
of December 31, 2019.  Our estimated proved reserves in the Northern Rocky Mountains as of December 31, 2019 were 453.5 MMBOE 
(54% oil), which represented 93% of our total estimated proved reserves and contributed 112.0 MBOE/d of average daily production in 
the fourth quarter of 2019. 

Across our acreage in the Williston Basin, we have implemented customized, right-sized completion designs which utilize the optimum 
volume of proppant, diversion, fluids and frac stages to increase well performance while reducing cost.  We plan to continue to use 
right-sized completion designs on wells we drill in 2020, while also utilizing state-of-the-art drilling rigs, high-torque mud motors and 
evolving 3-D bit cutter technology to reduce time-on-location and total well cost. Our engineers have worked with service providers to 
optimize fluid systems and bit designs to increase drill rate and hole cleaning resulting in higher capital efficiency in the drilling program. 
As of December 31, 2019, we had four rigs active in the Williston Basin. 

Central Rocky Mountains 

Our Central Rocky Mountains operations include properties at our Redtail field in the Denver-Julesburg Basin (“DJ Basin”) in Weld 
County, Colorado targeting the Niobrara and Codell/Fort Hays formations and encompassing approximately 96,400 gross (84,600 net) 
developed  and  undeveloped  acres  as  of  December 31,  2019.    Our  estimated  proved  reserves  in  the  Central  Rocky  Mountains  as  of 
December 31, 2019 were 23.1 MMBOE (61% oil), which represented 5% of our total estimated proved reserves and contributed 10.4 
MBOE/d of average daily production in the fourth quarter of 2019. 

36 

We have established production in the Niobrara “A”, “B” and “C” zones and the Codell/Fort Hays formations.  We completed 22 drilled 
uncompleted wells (“DUCs”) in our Redtail field during the first half of 2018, and no additional wells were drilled or completed in 
2019.  During 2019 we worked on maintaining base production in this area with improved artificial lift techniques and reductions in 
lease operating expenses.  

Our Redtail gas plant processes the associated gas produced from our wells in this area, and has a current inlet capacity of 50 MMcf/d.  
As of December 31, 2019, the plant was processing 22 MMcf/d. 

Other 

Our  other  operations  primarily  relate  to  non-core  assets  in  Colorado,  Mississippi,  North  Dakota,  Texas  and  Wyoming.    As  of 
December 31,  2019,  these  properties  contributed  8.8  MMBOE  (83%  oil)  of  proved  reserves  to  our  portfolio  of  operations,  which 
represented 2% of our total estimated proved reserves and contributed 0.6 MBOE/d of average daily production in the fourth quarter of 
2019. 

Reserves 

As of December 31, 2019 and 2018, all of our oil and gas reserves were attributable to properties within the United States.  A summary 
of our proved oil and gas reserves as of December 31, 2019 and 2018 based on average fiscal-year prices (calculated as the unweighted 
arithmetic average of the first-day-of-the-month price for each month within the 12-month period ended December 31, 2019 and 2018, 
respectively) is as follows:

Proved  reserves.    Estimates  of  proved  developed  and  undeveloped  reserves  are  inherently  imprecise  and  are  continually  subject  to 
revision based on production history, results of additional exploration and development, price changes and other factors. 

Total extensions and discoveries of 34.0 MMBOE in 2019 were primarily attributable to successful drilling in the Williston Basin.  Both 
the new wells drilled in this area as well as the PUD locations added as a result of drilling increased our proved reserves. 

Sales of minerals in place totaled 4.9 MMBOE during 2019 and were primarily attributable to the disposition of certain non-operated 
properties in North Dakota as further described in “Acquisitions and Divestitures” within Item 1 of this Annual Report on Form 10-K. 

In  2019,  revisions  to  previous  estimates  decreased  proved developed  and  undeveloped  reserves  by a  net amount  of  17.9  MMBOE.  
Included in this change were upward revisions of 48.0 MMBOE to proved undeveloped reserves primarily located in the Williston Basin 
in locations where we have significant development activity and past drilling success.  Offsetting these upward reserve revisions were: 
(i)  32.9  MMBOE  of  downward  adjustments  caused  by  lower  crude  oil,  NGL  and  natural  gas  prices  incorporated  into  our  reserve 
estimates at December 31, 2019 as compared to December 31, 2018, (ii) 19.3 MMBOE of downward adjustments primarily attributable 
to reservoir analysis and well performance across our Northern and Central Rockies assets and (iii) 13.7 MMBOE of proved undeveloped 
reserves no longer expected to be developed within five years from their initial recognition.

December 31, 2019.  The following table provides a reconciliation of our PUDs for the year ended December 31, 2019:

During 2019, we incurred $475 million in capital expenditures, or $11.10 per BOE, to drill and bring on-line 42.8 MMBOE of PUD 
reserves.  In addition, we added 19.4 MMBOE of PUDs from extensions and discoveries during the year primarily due to successful 
drilling in the Williston Basin.  We have made an investment decision and adopted a development plan to drill all of our individual PUD 
locations within five years of the date such PUDs were added.  In that regard, under our current 2020 development plan, we expect to 
convert approximately 48.1 MMBOE of PUDs to proved developed reserves during the year. 

Preparation of reserves estimates.  We maintain adequate and effective internal controls over the reserve estimation process as well as 
the underlying data upon which reserve estimates are based.  The primary inputs to the reserve estimation process are comprised of 
technical information, financial data, ownership interests and production data.  All field and reservoir technical information, which is 
updated annually, is assessed for validity when the reservoir engineers hold technical meetings with geoscientists, operations and land 
personnel to discuss field performance and to validate future development plans.  Current revenue and expense information is obtained 
from our accounting records, which are subject to our internal controls over financial reporting.  Internal controls over financial reporting 
are  assessed  for effectiveness  annually  using  the  criteria  set  forth in  Internal  Control –  Integrated  Framework  (2013)  issued  by  the 
Committee  of  Sponsoring  Organizations  of  the  Treadway Commission.    All current  financial  data  such as  commodity  prices,  lease 
operating expenses, transportation, gathering, compression and other expenses, production taxes and field commodity price differentials 
are updated in the reserve database and then analyzed to ensure that they have been entered accurately and that all updates are complete.  
Our current ownership in mineral interests and well production data are also subject to the aforementioned internal controls over financial 
reporting, and they are incorporated into the reserve database as well and verified to ensure their accuracy and completeness.  Once the 
reserve database has been entirely updated with current information, and all relevant technical support material has been assembled, our 
independent engineering firm Cawley, Gillespie & Associates, Inc. (“CG&A”) meets with our technical personnel in our Denver office 
to review field performance and future development plans.  Following this review, the reserve database and supporting data is furnished 
to CG&A so that they can prepare their independent reserve estimates and final report.  Access to our reserve database is restricted to 
specific members of the reservoir engineering department. 

CG&A is a Texas Registered Engineering Firm.  Our primary contact at CG&A is Mr. W. Todd Brooker, President.  Mr. Brooker is a 
State of Texas Licensed Professional Engineer.  Refer to Exhibit 99.2 of this Annual Report on Form 10-K for the Report of Cawley, 
Gillespie & Associates, Inc. and further information regarding the professional qualifications of Mr. Brooker. 

Trina Medina, our Director of Reservoir Engineering, is responsible for overseeing the preparation of the reserves estimates.  She has 
more than 25 years of broad reservoir engineering experience in the oil and gas industry, focused across conventional, unconventional 
and secondary recovery evaluation and development projects, including corporate reserves estimations.  Ms. Medina holds a Bachelor 
of  Science  degree  in  petroleum  engineering  from  the  Universidad  Central  de  Venezuela,  a  Master  of  Science  degree  in  reservoir 
engineering from Texas A&M University and a Master of Science degree in reservoir geoscience from the Institut Francais du Petrole.  
Ms. Medina is a member of the Society of Petroleum Engineers and the Society of Petroleum Evaluation Engineers.

Oil and Gas Drilling Activity 

We are engaged in numerous drilling activities on properties presently owned, and we intend to drill or develop other properties acquired 
in  the future.   The  following table  sets forth  our  oil  and  gas  drilling  activity  for  the last  three years.   A  dry  well 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.  A productive well is an exploratory, development or extension well that is not a dry well.  The information below 
should not be considered indicative of future performance, nor should it be assumed that there is necessarily any correlation between 
the number of productive wells drilled and quantities of reserves found.

As of December 31, 2019, we had four operated drilling rigs active on our properties in our Northern Rocky Mountains area.  As of 
December 31, 2019, we had 129 gross (57.1 net) operated and non-operated wells in the process of drilling, completing or waiting on 
completion. 

Hydraulic Fracturing 

Hydraulic fracturing is a common practice in the oil and gas industry that is used to stimulate production of hydrocarbons from tight oil 
and  gas  formations.   The  process  involves the injection of water,  sand and chemicals under pressure into formations  to  fracture the 
surrounding rock and stimulate production.  This process has typically been regulated by state oil and gas commissions.  However, as 
described in more detail in “Business – Regulation – Environmental Regulations – Hydraulic Fracturing” in Item 1 of this Annual Report 
on Form 10-K, the EPA has initiated the regulation of hydraulic fracturing, other federal agencies are examining hydraulic fracturing, 
and federal legislation is pending with respect to hydraulic fracturing.  We have utilized hydraulic fracturing in the completion of our 
wells  in  our  most active areas located  in  the  states  of  North  Dakota,  Montana  and Colorado  and  we  plan  to continue to  utilize  this 
completion methodology. 

Substantially all of our 126.6 MMBOE of proved undeveloped reserves are associated with hydraulic fracture treatments.

We are not aware of any environmental incidents, citations or suits that have occurred during the last three years related to hydraulic 
fracturing operations involving oil and gas properties that we operate or in which we own a non-operated interest. 

In order to minimize any potential environmental impact from hydraulic fracture treatments, we have taken the following steps: 

• 

• 

• 

• 

• 

• 

• 

we follow fracturing and flowback procedures that comply with or exceed North Dakota Industrial Commission or other state 
requirements; 

we train all company and contract personnel who are responsible for well preparation, fracture stimulation and flowback on our 
procedures; 

we  have  implemented  the  incremental  procedures  of  running  a  well  casing  caliper,  visually  inspecting  the  surface  joint  of 
intermediate  casing  and,  if  a  lighter  wall  joint  of  casing  or  drilling  wear  is  detected,  reducing  the  minimum  burst  pressure 
accordingly; 

for wells that are within one mile of major bodies of water or locations that lead to bodies of water, we construct berming around 
the well location prior to initiating fracturing operations; 

we run fracturing strings in certain situations when extra precaution is warranted, such as where the anticipated maximum treating 
pressure for the well is greater than the pressure rating of the intermediate casing or in areas located within one mile of major 
bodies of water; 

we conduct annual emergency incident response drills in our active areas; and 

we are a member of the Sakakawea Area Spill Response LLC (“SASR”), which is comprised of 17 oil and gas related companies 
operating in the Missouri River and Lake Sakakawea regions of North Dakota.  Members agreed to share spill response resources 
and maintain SASR-owned water response equipment that can be accessed quickly in the early stages of a spill. 

While we do not have insurance policies in effect that are intended to provide coverage for losses solely related to hydraulic fracturing 
operations, we do have general liability and excess liability insurance policies that we believe would cover third-party claims related to 
hydraulic fracturing operations and associated legal expenses in accordance with, and subject to, the terms of such policies. 

Delivery Commitments 

Our production sales agreements contain customary terms and conditions for the oil and natural gas industry, generally provide for sales 
based on prevailing market prices in the area, and generally have terms of one year or less. 

As of December 31, 2019, we have entered into three physical delivery contracts which require us to deliver fixed volumes of crude oil.  
One of these contracts is tied to crude oil production from the Williston Basin and requires delivery of 10 MBbl/d for a term of seven 
years.  The effective date of this contract is contingent upon the completion of certain related pipelines, which are currently expected to 
be brought online in 2021.  Under the terms of this contract, if we fail to deliver the committed volumes we will be required to pay a 
deficiency payment of $5.75 per undelivered Bbl, subject to upward adjustment, over the duration of the contract.  However, we believe 
that our production and reserves are sufficient to fulfill the delivery commitment in the Williston Basin, and we therefore expect to avoid 
any payments for deficiencies under this contract.

Our two remaining physical delivery contracts are effective as of December 31, 2019.  One of these contracts is tied to oil production at 
our Sanish field in Mountrail County, North Dakota and is effective for a term of seven years ending May 31, 2024.  The other contract 
is tied to oil production at our Redtail field in Weld County, Colorado and terminates in April 2020.  The following table summarizes 
our Sanish and Redtail delivery commitments as of December 31, 2019:

Under the terms of the Sanish contract, if we fail to deliver the committed volumes we will be required to pay a deficiency payment of 
$7.00 per undelivered Bbl, subject to upward adjustment, over the duration of the contract.  However, we believe that our production 
and reserves are sufficient to fulfill the delivery commitment at our Sanish field, and we therefore expect to avoid any payments for 
deficiencies under this contract. 

Under the terms of the Redtail contract, if we fail to deliver the committed volumes we are required to pay a deficiency payment that 
currently totals $5.24 per undelivered Bbl over the remaining term of the contract.  We have determined that it is not probable that future 
oil production from  our  Redtail  field  will  be  sufficient to meet  the minimum  volume  requirements  specified in the  related  physical 
delivery  contract, and as  a  result,  we  expect to  make  deficiency payments  for any  shortfalls  in  delivering the  minimum  committed 
volumes.  We recognize any monthly deficiency payments in the period in which the underdelivery takes place and the related liability 
has been incurred. During 2019, 2018 and 2017, total deficiency payments under this contract, as well as a second Redtail contract that 
we terminated in February 2018, amounted to $64 million, $39 million and $66 million, respectively. 

Item 3.       Legal Proceedings 

We are subject to litigation claims and governmental and regulatory proceedings arising in the ordinary course of business.  While the 
outcome  of these lawsuits and  claims  cannot  be  predicted with  certainty, it  is  management’s opinion  that  the  loss  for any  litigation 
matters and claims we are involved in that are reasonably possible to occur will not have a material adverse effect, individually or in the 
aggregate, on our consolidated financial position, cash flows or results of operations. 

We are involved in litigation related to a payment arrangement with a third party which currently claims damages up to $41 million, as 
well as court costs and interest, that is scheduled to go to trial in May 2020.  Certain amounts have been accrued in accrued liabilities 
and  other  in  the  consolidated  balance  sheet  as  of  December 31,  2019  and  general  and  administrative  expenses  in  the  consolidated 
statement of operations for the year ended December 31, 2019 based on the determination that it is probable that a loss has been incurred 
and can be reasonably estimated. 

Item 4.       Mine Safety Disclosures 

Not applicable.

PART II 

Item 5.        Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities 

Whiting Petroleum Corporation’s common stock is traded on the New York Stock Exchange under the symbol “WLL”.  On February 20, 
2020, there were 444 holders of record of our common stock. 

On  November 8,  2017, our Board  of  Directors approved  a reverse  stock  split  of  our common  stock  at a  ratio  of  one-for-four  and  a 
reduction in the number of authorized shares of our common stock from 600,000,000 shares to 225,000,000.  Our common stock began 
trading on a split-adjusted basis on November 9, 2017 upon opening of the markets.  All share and per share amounts in this Annual 
Report on Form 10-K for periods prior to November 2017 have been retroactively adjusted to reflect the reverse stock split. 

We have not paid any cash dividends on our common stock since we were incorporated in July 2003, and we do not anticipate paying 
any such dividends on our common stock in the foreseeable future.  We currently intend to retain future earnings, if any, to finance the 
expansion of our business.  Our future dividend policy is within the discretion of our board of directors and will depend upon various 
factors, including our financial position, cash flows, results of operations, capital requirements and investment opportunities.   

Information relating to compensation plans under which our equity securities are authorized for issuance is set forth in Part III, Item 12 
of this Annual Report on Form 10-K. 

The following information in this Item 5 of this Annual Report on Form 10-K is not deemed to be “soliciting material” or to be “filed” 
with the SEC or subject to Regulation 14A or 14C under the Securities Exchange Act of 1934 or to the liabilities of Section 18 of the 
Securities Exchange Act of  1934, and will not be deemed to be incorporated by reference into any filing under the Securities Act of 
1933 or the Securities Exchange Act of 1934, except to the extent we specifically incorporate it by reference into such a filing. 

The following graph compares on a cumulative basis changes since December 31, 2014 in (a) the total stockholder return on our common 
stock  with  (b) the  total  return  on  the  Standard &  Poor’s  Composite  500  Index  and  (c) the  total  return  on  the  Dow  Jones  U.S. 
Exploration & Production Index.  Such changes have been measured by dividing (a) the sum of (i) the cumulative amount of dividends 
for the measurement period, assuming dividend reinvestment, and (ii) the difference between the price per share at the end of and the 
beginning of the measurement period, by (b) the price per share at the beginning of the measurement period.  The graph assumes $100 
was  invested  on  December 31,  2014  in  our  common  stock,  the  Standard &  Poor’s  Composite  500  Index  and  the  Dow  Jones  U.S. 
Exploration & Production Index, respectively.

Unless  the  context  otherwise  requires,  the  terms  “Whiting”,  “we”,  “us”,  “our”  or  “ours”  when  used  in  this  Item refer  to  Whiting 
Petroleum Corporation, together with its consolidated subsidiaries, Whiting Oil and Gas Corporation (“Whiting Oil and Gas”), Whiting 
US Holding Company, Whiting Canadian Holding Company ULC, Whiting Resources Corporation and Whiting Programs, Inc.  When 
the context requires, we refer to these entities separately.  This document contains forward-looking statements, which give our current 
expectations or forecasts of future events.  Please refer to “Forward-Looking Statements” at the end of this Item for an explanation of 
these types of statements. 

Overview 

We are an independent oil and gas company engaged in development, production, acquisition and exploration activities primarily in the 
Rocky Mountains region of the United States.  Our current operations and capital programs are focused on organic drilling opportunities 
and  on the  development  of previously  acquired  properties, specifically  on projects that  we believe  provide  the  greatest  potential  for 
repeatable  success and  production  growth,  while  selectively  pursuing  acquisitions that complement  our existing core  properties  and 
exploring other basins where we can apply our existing knowledge and expertise to build production and add proved  reserves.  As a 
result of lower crude oil prices during 2017 and 2018, we significantly reduced our level of capital spending and focused our drilling 
activity on projects that provide the highest rate of return, while closely aligning our capital spending with cash flows generated from 
operations.  During 2019, we focused on developing our large resource play in the Williston Basin of North Dakota and Montana, while 
continuing  to  closely  align  our  capital  spending  with  cash  flows  generated  from  operations.    We  continually  evaluate  our  property 
portfolio  and  sell  properties  when  we  believe that the  sales  price  realized  will  provide  an  above  average  rate  of  return  or  when  the 
property no longer matches the profile of properties we desire to own, such as the asset sales discussed below under “Acquisition and 
Divestiture Highlights” and in the “Acquisitions and Divestitures” footnote in the notes to the consolidated financial statements. 

Our  revenue,  profitability  and future  growth  rate  depend  on many  factors  which  are  beyond  our  control,  such  as  oil  and  gas prices, 
economic, political and regulatory developments, competition from other sources of energy,  and the other items discussed under the 
caption “Risk Factors” in Item 1A of this Annual Report on Form 10-K.  Oil and gas prices historically have been volatile and may 
fluctuate widely in the future.  The following table highlights the quarterly average NYMEX price trends for crude oil and natural gas 
prices since the first quarter of 2018:

Lower oil, NGL and natural gas prices may not only decrease our revenues on a per unit basis, but may also reduce the amount of oil 
and natural gas that we can produce economically and therefore potentially lower our oil and gas reserve quantities.  Substantial and 
extended declines in oil, NGL and natural gas prices have resulted, and may result, in impairments of our proved oil and gas properties 
or undeveloped acreage (such as the impairments discussed below under “Results of Operations”) and may materially and adversely 
affect  our  future  business,  financial  condition,  cash  flows,  results  of  operations,  liquidity  or  ability  to  finance  planned  capital 
expenditures.  In addition, lower commodity prices may reduce the amount of our borrowing base under our credit agreement, which is 
determined at the discretion of our lenders and is based on the collateral value of our proved reserves that have been mortgaged to the 
lenders, as occurred with our most recent semi-annual redetermination where the borrowing base was lowered from $2.25 billion to 
$2.05 billion in October 2019.  Upon a redetermination, if total outstanding credit exposure exceeds the redetermined borrowing base, 
we will be required to prepay outstanding borrowings in an aggregate principal amount equal to such excess in six substantially equal 
monthly installments.  Alternatively, higher oil prices may result in significant mark-to-market losses being incurred on our commodity-
based derivatives. 

For a discussion of material changes to our proved reserves from December 31, 2018 to December 31, 2019 and our ability to convert 
PUDs to proved developed reserves, refer to “Reserves” in Item 2 of this Annual Report on Form 10-K.  Additionally, for a discussion 
relating to the minimum remaining terms of our leases, refer to “Acreage” in Item 2 of this Annual Report on Form 10-K.

2019 Highlights and Future Considerations 

Operational Highlights 

Northern Rocky Mountains – Williston Basin 

Our properties in the Williston Basin of North Dakota and Montana target the Bakken and Three Forks formations.  Net production 
from the Williston Basin averaged 112.0 MBOE/d for the fourth quarter of 2019, representing a 1% increase from 111.4 MBOE/d in 
the third quarter of 2019.  Across our acreage in the Williston Basin, we have implemented customized, right-sized completion designs 
which  utilize the  optimum  volume  of proppant, fluids,  and frac  stages  to  increase  well  performance  while  reducing  cost.  We  have 
increased stages pumped per day by focusing on new technologies such as quick-install wellhead connections and frac plug innovations.  
We plan to continue to use right-sized completion designs on wells we drill in 2020, while also utilizing state-of-the-art drilling rigs, 
high-torque mud motors and 3-D bit cutter technology to reduce time-on-location and total well cost.  As of December 31, 2019, we had 
four rigs active in the Williston Basin.  We drilled 31 wells and put 35 wells on production in this area during the fourth quarter of 2019.  
First quarter 2020 production has been impacted by severe weather conditions and associated electric submersible pump failures on 
multiple high value wells.  We estimate that this will impact first quarter 2020 production results by approximately 5 MBOE/d. 

Central Rocky Mountains – Denver-Julesburg Basin 

Our Redtail field in the Denver-Julesburg Basin (“DJ Basin”) in Weld County, Colorado targets the Niobrara and Codell/Fort  Hays 
formations.  Net production from the Redtail field averaged  10.4 MBOE/d in the fourth quarter of 2019, representing a 7% decrease 
from  11.2  MBOE/d  in  the  third  quarter  of  2019.   We  have established  production  in the  Niobrara  “A”,  “B”  and  “C” zones and  the 
Codell/Fort Hays formations.  We completed 22 drilled uncompleted wells (“DUCs”) in our Redtail field during the first half of 2018, 
and no additional wells were drilled or completed in 2019.  During 2019 we worked on maintaining base production with  improved 
artificial lift techniques and reductions in lease operating expenses.   

Our Redtail gas plant processes the associated gas produced from our wells in this area, and has a current inlet capacity of 50 MMcf/d.  
As of December 31, 2019, the plant was processing 22 MMcf/d. 

Financing Highlights 

In  September 2019,  we  paid  $299 million to  complete  a cash  tender offer  for  $300  million aggregate  principal  amount  of  our  2020 
Convertible Senior Notes, which payment consisted of the 99.0% purchase price plus all accrued and unpaid interest on the notes. 

In September 2019, we paid $24 million to repurchase $25 million aggregate principal amount of our 2021 Senior Notes, which payment 
consisted of the average 94.708% purchase price plus all accrued and unpaid interest on the notes.  In October 2019, we paid an additional 
$72 million to repurchase $75 million aggregate principal amount of the 2021 Senior Notes, which payment consisted of the average 
95.467% purchase price plus all accrued and unpaid interest on the notes. 

We financed the tender offer and repurchases with borrowings under our credit agreement.  Refer to the “Long Term Debt” footnote in 
the notes to the consolidated financial statements for more information on the tender offer and repurchases.  

In October 2019, the borrowing base under our credit agreement was reduced from $2.25 billion to $2.05 billion in connection with the 
November 1, 2019 regular borrowing base redetermination, with no change to the aggregate commitments of $1.75 billion. 

2020 Exploration and Development Budget 

Our 2020 exploration and development (“E&D”) budget is a range of $585 million to $620 million, which we expect to fund substantially 
with net cash provided by our operating activities and cash on hand, and represents a decrease from the $778 million incurred on E&D 
expenditures during 2019.  This reduced spending is primarily attributable  to our commitment to closely align capital spending with 
cash  flows  generated  from  operations.    To  the  extent  net  cash  provided  by  operating  activities  is  higher  or  lower  than  currently 
anticipated, we would generate more or less free cash flow than we currently anticipate, and may adjust our E&D budget and attempt to 
enter into agreements with industry partners, divest certain oil and gas property interests, adjust borrowings outstanding under our credit 
facility or access the capital markets as necessary.  Approximately 90% of the midpoint of our 2020 E&D budget currently is allocated 

49 

to drilling and completion activity.  Of our existing development opportunities, we believe this allocation of our capital presents the 
opportunity for the highest return and most efficient use of our capital. 

Acquisition and Divestiture Highlights  

On July 29, 2019, we completed the divestiture of our interests in 137 non-operated, producing oil and gas wells located in McKenzie, 
Mountrail and Williams counties of North Dakota for aggregate sales proceeds of $27 million (before closing adjustments).   

On August 15, 2019, we completed the divestiture of our interests in 58 non-operated, producing oil and gas wells located in Richland 
County, Montana and Mountrail and Williams counties of North Dakota for aggregate sales proceeds of $26 million (before closing 
adjustments).   

On a combined basis, the divested properties consisted of less than 1% of our estimated proved reserves as of December 31, 2018 and 
our April 2019 average daily production. 

On  January 9,  2020,  we  completed  the  divestiture  of  our  interests  in  30  non-operated,  producing  oil  and  gas  wells  and  related 
undeveloped  acreage  located  in  McKenzie  County,  North  Dakota  for  aggregate  sales  proceeds  of  $25  million  (before  closing 
adjustments).  The divested properties consisted of less than 1% of our estimated proved reserves as of December 31, 2019 and 1% of 
our average daily production for the year ended December 31, 2019. 

Restructuring 

On July 31, 2019, we executed a workforce reduction as part of an organizational redesign and cost reduction strategy to better align 
our business with the current operating environment and drive long-term value.  We incurred a one-time net charge of $8 million to 
general and administrative expense during 2019 related to this restructuring.

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018 

Oil, NGL and Natural Gas Sales.  Our oil, NGL and natural gas sales revenue decreased $509 million to $1.6 billion when comparing 
2019 to 2018.  Changes in sales revenue between periods are due to changes in production sold and changes in average commodity 
prices realized (excluding the impacts of hedging).  For 2019, decreases in total production accounted for approximately $90 million of 
the change in revenue and decreases in commodity prices realized accounted for approximately $419 million of the change in revenue 
when comparing to 2018. 

Our oil volumes decreased 5% and our NGL and natural gas sales volumes increased 3% and 8%, respectively, during 2019 compared 
to 2018.  The oil volume decrease was mainly attributable to normal field production decline primarily in the DJ Basin, where we ceased 
our development activity during 2019, as well as the result of infrastructure constraints in the Williston Basin and the impact of severe 
weather  experienced  in  both  the  Williston  Basin  and  the  DJ  Basin  during  2019.    This  decrease  was  partially  offset  by  increased 
production from new wells drilled and completed in the Williston Basin.  The NGL and natural gas volume increases between periods 
generally relate to new wells drilled and completed in the Williston Basin over the last twelve months, as well as additional volumes 
processed as more wells were connected to gas processing plants in the Williston Basin in an effort to increase our overall gas capture 
rate in this area and reduce flared volumes.  Many of the new Williston Basin wells are in areas with higher gas-to-oil production ratios

than previously drilled areas.  These NGL and natural gas volume increases were partially offset by normal field production decline 
across several of our areas.   

Our average price for oil (before the effects of hedging), NGLs and natural gas decreased 15%, 67% and 66%, respectively, between 
periods.   Our average  sales  price  realized  for  oil  is  impacted  by deficiency payments  we  were making  under  two physical  delivery 
contracts at our Redtail field due to our inability to meet the minimum volume commitments under these contracts.  During 2019 and 
2018, our total average sales price realized for oil was $2.14 per Bbl lower and $1.25 per Bbl lower, respectively, as a result of these 
deficiency payments.  On February 1, 2018, we paid $61 million to the counterparty to one of these Redtail delivery contracts to settle 
all future minimum volume commitments under the agreement.  The remaining agreement will continue to negatively impact the price 
we  receive  for  oil  from  our  Redtail  field  through  April 2020,  when  the  contract  terminates.    Refer  to  the  “Commitments  and 
Contingencies” footnote in the notes to the consolidated financial statements for more information on these physical delivery contracts 
and  the  related  deficiency  payments.    Our  average  sales  price  realized  for  natural  gas  is  impacted  by  rising  market  differentials  as 
compared to NYMEX as well as high fixed third-party costs for transportation, gathering and compression services. 

Lease Operating Expenses.  Our lease operating expenses (“LOE”) during 2019 were $328 million, a $17 million increase over 2018.  
This increase was primarily due to new wells put on production in the Williston Basin during 2019 as well as rising costs of oilfield 
goods and services.  These increases were partially offset by cost savings as a result of our company restructuring in July 2019 and cost 
reduction initiatives implemented during 2019.  Refer to “Restructuring” for more information on this event. 

Our lease operating expenses on a BOE basis also increased when comparing 2019 to 2018.  LOE per BOE amounted to $7.17 during 
2019, which represents an increase of $0.49 per BOE (or 7%) from 2018.  This increase was mainly due to the overall increase in LOE 
expense discussed above, as well as lower overall production volumes between periods. 

Transportation, Gathering, Compression and Other.  Our transportation, gathering, compression and other expenses (“TGC”) during 
2019 were $42 million, a $6 million decrease over 2018. This decrease was primarily due to lower realized NGL prices during 2019, 
which led to lower gas processing fees under our percentage-of-proceeds contracts as compared to 2018. 

TGC on a BOE basis also decreased when comparing 2019 to 2018. TGC per BOE amounted to $0.93 during 2019, which represents a 
decrease of $0.10 per BOE (or 10%) from 2018.  This decrease was mainly due to the overall decrease in TGC expense discussed above, 
partially offset by lower overall production volumes between periods. 

Production  and  Ad  Valorem  Taxes.    Our  production  and  ad  valorem  taxes  during  2019  were  $138  million,  a  $34  million  decrease  
compared  to 2018,  which  was primarily due to  lower  sales revenue  between periods.  Our  production taxes, however, are  generally 
calculated as a percentage of net sales revenue before the effects of hedging, and this percentage on a company-wide basis was 8.6% 
and 7.8% for 2019 and 2018, respectively.  Our production tax rate for 2019 was higher than the rate for 2018 primarily due to our 
concentration of development over the last twelve months in the Williston Basin states of North Dakota and Montana, which have higher 
tax rates than Colorado where we have had limited development activity over the past twelve months.  This increase in rate was partially 
offset by certain North Dakota wells receiving stripper well status, which reduces the rate from 10% to 5%. 

Depreciation, Depletion and Amortization.  Our depreciation, depletion and amortization (“DD&A”) expense increased $35 million in 
2019 as compared to 2018.  The components of our DD&A expense were as follows (in thousands): 

Depletion  
Accretion of asset retirement obligations

DD&A increased between periods primarily due to $36 million in higher depletion expense, consisting of a $52 million increase related 
to a higher depletion rate between periods, partially offset by a $16 million decrease due to lower overall production volumes during 
2019.  On a BOE basis, our overall DD&A rate of $17.82 for 2019 was 7% higher than the rate of $16.73 in 2018.  The primary factors 
contributing to this higher DD&A rate were a recent shift in our development activity to areas with higher average historical DD&A 
rates and downward revisions to proved reserves over the last twelve months.

Exploration costs increased  $15  million between  periods  primarily  due  to increased  deficiency  fees  paid under  our  produced  water 
disposal agreement driven by reduced drilling and completions at our Redtail field during 2019 compared to 2018. 

Impairment expense in 2019 primarily related to the amortization of leasehold costs associated with individually insignificant unproved 
properties.  Impairment expense in 2018 primarily related to (i) $29 million of leasehold amortization costs associated with individually 
insignificant unproved properties and (ii) $8 million in impairment write-downs of undeveloped acreage costs for leases where we have 
no future plans to drill. 

General and Administrative Expenses.  We report general and administrative (“G&A”) expenses net of third-party reimbursements and 
internal allocations.  The components of our G&A expenses were as follows (in thousands):

G&A expense before reimbursements and allocations increased $5 million during 2019 as compared to 2018 primarily due to an $8 
million one-time net charge related to the company restructuring during 2019 as well as higher legal and litigation costs.  In addition, 
G&A expense for 2018 includes $5 million of credits to bad debt expense related to the collection of certain receivables that had been 
previously deemed uncollectible.  These factors resulting in increased G&A expense for 2019 were partially offset by lower employee 
compensation costs as a result of the restructuring.  The decrease in reimbursements and allocations in 2019 was primarily the result of 
lower  headcount  due  to  the  restructuring  as  well  as  lower  development  activity  during  the  fourth  quarter  of  2019.    Refer  to 
“Restructuring” for more information on the company restructuring. 

Our  G&A  expenses  on  a  BOE  basis  also  increased  between  periods.    G&A  expense  per  BOE  amounted  to  $2.89  in  2019,  which 
represents  an  increase  of  $0.25  per  BOE  (9%)  from  2018.    This  increase  was  mainly  due  to  the  overall  increase  in  G&A  expense 
discussed above, as well as lower overall production volumes between periods.  

Derivative Loss, Net.  Our commodity derivative contracts are marked to market each quarter with fair value gains and losses recognized 
immediately in earnings as derivative (gain) loss, net.  Cash flow, however, is only impacted to the extent that settlements under these 
contracts result in making or receiving a payment to or from the counterparty.  Derivative loss, net amounted to $54 million and $17 
million for 2019 and 2018, respectively.  These losses primarily related to our collar, swap and option commodity derivative contracts 
and resulted from the upward shift in the futures curve of forecasted commodity prices for crude oil during the respective periods.

The decrease in interest expense of $6 million between periods was mainly attributable to lower interest incurred on our notes in 2019 
compared to 2018 resulting from the redemption of the 2019 Notes in January 2018, the tender offer for the 2020 Convertible Senior 
Notes in September 2019 and the repurchases of the 2021 Senior Notes in September and October 2019.  Refer to the “Long-Term Debt” 
footnote in the notes to the consolidated financial statements for more information on these debt transactions. 

Our weighted average debt outstanding during 2019 was $2.9 billion versus $3.0 billion for 2018.  Our weighted average effective cash 
interest rate was 5.5% during both 2019 and 2018. 

Gain (Loss) on Extinguishment of Debt.  During 2019, we recognized a gain on extinguishment of debt of $8 million.  In September 
2019, we paid $299 million to purchase $300 million aggregate principal amount of the 2020 Convertible Senior Notes in a cash tender 
offer and recognized a $4 million gain on extinguishment of debt.  Additionally, in September and October 2019, we paid $96 million 
to repurchase $100 million aggregate principal amount of the 2021 Senior Notes and recognized a $4 million gain on extinguishment of 
debt.  During 2018, we redeemed all of the remaining $961 million aggregate principal amount of 2019 Senior Notes and recognized a 
$31 million loss on extinguishment of debt.  Refer to the “Long-Term Debt” footnote in the notes to the consolidated financial statements 
for more information on these debt transactions. 

Income Tax Expense (Benefit).  Income tax expense for 2019 totaled $72 million as compared to $1 million for 2018.  As a result of our 
positive  pre-tax  income  in  2018,  we  transitioned from  a net  deferred  tax asset  position to a  net  deferred  tax  liability  position  as  of 
December 31, 2018.  Accordingly, we released the valuation allowance related to our general net deferred tax assets that was established 
in 2017 and recognized $1 million in deferred tax expense related to U.S. income tax for the year ended December 31, 2018.  As a result 
of pre-tax losses in 2019, we transitioned from a net deferred tax liability position to a net deferred tax asset position for U.S. income 
taxes which resulted in the recognition of a full valuation allowance on our deferred tax assets again during the second quarter of 2019 
and recognition of a $1 million deferred U.S. tax benefit.  Additionally, during the fourth quarter of 2019, we recognized $74 million of 
Canadian deferred tax expense associated with the outside basis difference in Whiting Canadian Holding Company ULC pursuant to 
ASC 740-30-25-17.  Refer to the “Income Taxes” footnote in the notes to the consolidated financial statements for more information on 
this deferred tax liability. 

Our effective tax rates for 2019 and 2018 differ from the U.S. statutory income tax rate primarily due to the effects of state income taxes, 
permanent taxable differences and changes in the valuation allowance.  Our overall effective tax rate decreased from 0.4% for 2018 to 
(42.7)% for 2019 primarily due to the recognition of the outside basis difference in Whiting Canadian Holding Company ULC. 

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 

For  discussion  on  the  year  ended  December  31,  2018  compared  to  the  year  ended  December 31,  2017,  refer  to  Part  II,  Item  7 
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2018 Annual Report on Form 10-K 
filed with the SEC on February 28, 2019 under the subheading “Year Ended December 31, 2018 Compared to Year Ended December 31, 
2017.” 

Liquidity and Capital Resources 

Overview.  At December 31, 2019, we had $9 million of cash on hand and $4.0 billion of equity, while at December 31, 2018, we had 
$14 million of cash on hand and $4.3 billion of equity. 

One of the primary sources of variability in our cash flows from operating activities is commodity price volatility, which we partially 
mitigate through the use of commodity hedge contracts.  Oil accounted for 65% and 67% of our total production in 2019 and 2018, 

54 

 
 
 
 
 
 
 
 
 
 
     
     
 
 
 
 
 
 
 
 
 
 
 
 
respectively.  As a result, our operating cash flows are more sensitive to fluctuations in oil prices than they are to fluctuations in NGL 
or natural gas prices.  As of February 20, 2020, we had contracts covering the sale of  31 MMBbl of oil per day for the remainder of 
2020  and  6  MMBbl  of oil  per day for all  of  2021.    For  further information  on our  outstanding  derivatives  refer  to  the  “Derivative 
Financial Instruments” footnote in the notes to the consolidated financial statements. 

Cash Flows from 2019 Compared to 2018.  During 2019, we generated $756 million of cash provided by operating activities, a decrease 
of $336 million from 2018.  Cash provided by operating activities decreased primarily due to lower realized sales prices for oil, NGLs 
and  natural  gas,  lower  crude  oil  production  volumes,  as  well  as  higher  lease  operating  expenses,  exploration  costs  and  cash  G&A 
expenses.  These negative factors were partially offset by higher NGL and natural gas production volumes, a decrease in cash settlements 
paid on our derivative contracts, and lower production and ad valorem taxes, cash interest expense and TGC for 2019 compared to 2018.  
Refer to “Results of Operations” for more information on the impact of volumes and prices on revenues and for more information on 
increases and decreases in certain expenses during 2019. 

During 2019, cash flows from operating activities, $375 million of net borrowings under our credit agreement, proceeds from the sale 
of properties and cash on hand were used to finance $793 million of drilling and development expenditures, the  repurchase of $300 
million aggregate  principal  amount  of  2020  Convertible  Senior  Notes  and  $100  million  aggregate principal  amount  of  2021  Senior 
Notes, and $6 million of other property and equipment purchases. 

Cash Flows from 2018 Compared to 2017.  For discussion on cash flows for the year ended December 31, 2018 compared to the year

We continually evaluate our capital needs and compare them to our capital resources.  Our 2020 E&D budget is a range of $585 million 
to $620 million, which we expect to fund substantially with net cash provided by operating activities and cash on hand, and represents 
a decrease from the $778 million incurred on E&D expenditures during 2019.  We believe that should additional attractive acquisition 
opportunities arise, we will attempt to finance additional capital expenditures through agreements with industry partners, divestitures of 
certain oil and gas property interests, borrowings under our credit agreement or by accessing the capital markets.  Our level of E&D 
expenditures is largely discretionary, and the amount of funds we devote to any particular activity may increase or decrease significantly 
depending on commodity prices, cash flows, available opportunities and development results, among other factors.  We believe that we 
have sufficient liquidity and capital resources to execute our business plan over the next twelve months and for the foreseeable future.  
With  our  expected cash  flow  streams, commodity  price  hedging  strategies, current liquidity  levels  (including  availability under  our 
credit agreement), access to debt and equity markets and flexibility to modify future capital expenditure programs, we expect to be able 
to fund all planned capital programs and debt repayments, comply with our debt covenants, and meet other obligations that may arise 
from our oil and gas operations. 

Credit  Agreement.   Whiting  Oil and  Gas,  our  wholly  owned  subsidiary,  has a  credit  agreement  with a  syndicate  of  banks that  as  of 
December 31,  2019  had  a  borrowing  base  and  aggregate  commitments  of  $2.05  billion  and  $1.75  billion,  respectively.    As  of 
December 31, 2019, we had $1.4 billion of available borrowing capacity under the credit agreement, which was net of $375 million of 
borrowings outstanding and $2 million in letters of credit outstanding. 

The borrowing base under the credit agreement is determined at the discretion of our lenders, based on the collateral value of our proved 
reserves that have been mortgaged to such lenders, and is subject to regular redeterminations on May 1 and November 1 of each year, 

55 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
as well as special redeterminations described in the credit agreement, in each case which may reduce the amount of the borrowing base.  
Upon a redetermination of our borrowing base, either on a periodic or special redetermination date, if total outstanding credit exposure 
exceeds the redetermined borrowing base, we will be required to prepay outstanding borrowings in an aggregate principal amount equal 
to such excess in six substantially equal monthly installments.  In October 2019, the borrowing base under our credit agreement was 
reduced from $2.25 billion to $2.05 billion in connection with the November 1, 2019 regular borrowing base redetermination, with no 
change to the aggregate commitments of $1.75 billion. 

A portion of the revolving credit facility in an aggregate amount not to exceed $50 million may be used to issue letters of credit for the 
account  of Whiting  Oil and  Gas  or  other  designated  subsidiaries  of  ours.    As  of  December 31,  2019,  $48  million  was available  for 
additional letters of credit under the agreement. 

The  credit  agreement  provides  for  interest  only  payments  until  maturity,  when  the  credit  agreement  expires  and  all  outstanding 
borrowings are due.  Interest under the credit agreement accrues at our option at either (i) a base rate for a base rate loan plus a margin 
between 0.50% and 1.50% based on the ratio of outstanding borrowings to the borrowing base, where the base  rate is defined as the 
greatest of the prime rate, the federal funds rate plus 0.5% per annum, or an adjusted LIBOR rate plus 1.0% per annum, or (ii) an adjusted 
LIBOR rate for a Eurodollar loan plus a margin of 1.50% and 2.50% based on the ratio of outstanding borrowings to the borrowing 
base.  Additionally, we also incur commitment fees of 0.375% or 0.50% based on the ratio of outstanding borrowings to the borrowing 
base on the unused portion of the aggregate commitments of the lenders under the credit agreement. 

The credit agreement matures on April 12, 2023, provided that if at any time and for so long as any senior notes (other than the 2020 
Convertible Senior Notes) have a maturity date prior to 91 days after April 12, 2023, the maturity date shall be the date that is 91 days 
prior to the maturity of such senior notes.  On September 13, 2019, we amended the credit agreement to, among other things, permit the 
repurchase, redemption, prepayment or other acquisition or retirement for value of any senior notes (as defined in the credit agreement) 
if (i) such transaction is for a price not greater than an amount equal to par plus accrued and unpaid interest and fees and any applicable 
make-whole premium, (ii) immediately after giving effect to such transaction, there is unused availability under the facility of not less 
than the greater of $100 million or 15% of the then effective total commitments, and (iii) our ratio of consolidated total debt as of the 
date of such transaction (upon giving effect thereto) to EBITDAX (as defined in the credit agreement) during the last four quarters is 
not greater than 3.25 to 1.0.  Our business plan includes the intent to refinance certain senior notes, including our convertible senior 
notes  due  in  2020  and  our  senior  notes  due  in  2021,  as  permitted  by  the  September 13,  2019  amendment  to  the  credit  agreement.  
Consequently, we have classified the credit agreement as long-term debt. 

The credit agreement contains restrictive covenants that may limit our ability to, among other things, incur additional indebtedness, sell 
assets, make loans to others, make investments, enter into mergers, enter into hedging contracts, incur liens and engage in certain other 
transactions without the prior consent of our lenders.  Except for limited exceptions, the credit agreement also restricts our ability to 
make any dividend payments or distributions on our common stock.  These restrictions apply to all of our restricted subsidiaries (as 
defined in the credit agreement).  As of December 31, 2019, there were no retained earnings free from restrictions. 

The credit agreement requires us, as of the last day of any quarter, to maintain the following ratios (as defined in the credit agreement): 
(i) a consolidated current assets to consolidated current liabilities ratio (which includes an add back of the available borrowing capacity 
under the credit agreement) of not less than 1.0 to 1.0 and (ii) a total debt to the last four quarters’ EBITDAX ratio of not greater than 
4.0 to 1.0.  As of December 31, 2019, we were in compliance with the covenants under the credit agreement.  While not required to 
maintain compliance with covenants, our business plan may include property divestitures and utilizing our credit facility or  accessing 
capital markets to repay outstanding debt.  

For further information on the loan security related to our credit agreement, refer to the “Long-Term Debt” footnote in the notes to the 
consolidated financial statements. 

Under Whiting Oil and Gas’ credit agreement, a cross default provision provides that a default under certain other debt of the Company 
or certain of its subsidiaries in an aggregate principal amount exceeding $100 million may constitute an event of default under such 
credit agreement.  Additionally, under the indentures governing our senior notes and senior convertible notes, a cross-default provision 
provides that a default under certain other debt of the Company or certain of its subsidiaries in an aggregate principal amount exceeding 
$100 million (or $50 million in the case of the 2021 Senior Notes) may constitute an event of default under such indenture. 

Senior Notes.  In December 2017, we issued at par $1.0 billion of 6.625% Senior Notes due January 15, 2026 (the “2026 Senior Notes”).  
In March 2015, we issued at par $750 million of 6.25% Senior Notes due April 1, 2023 (the “2023 Senior Notes”).  In September 2013, 

56 

we issued at par $1.1 billion of 5.0% Senior Notes due March 15, 2019 (the “2019 Senior Notes”) and $800 million of 5.75% Senior 
Notes due  March 15,  2021,  and  issued  at  101%  of  par  an  additional  $400  million  of  5.75%  Senior  Notes due  March 15,  2021 
(collectively the “2021 Senior Notes” and together with the 2023 Senior Notes and the 2026 Senior Notes, the “Senior Notes”).   

During 2016, we exchanged (i) $139 million aggregate principal amount of our 2019 Senior Notes, (ii) $326 million aggregate principal 
amount of our 2021 Senior Notes, and (iii) $342 million aggregate principal amount of our 2023 Senior Notes, for the same aggregate 
principal  amount  of  convertible  notes.    Subsequently  during  2016, all  $807  million aggregate  principal  amount  of  these convertible 
notes was converted into approximately 19.8 million shares of our common stock pursuant to the terms of the notes. 

Redemption of 2019 Senior Notes.  In January 2018, we paid $1.0 billion to redeem all of the then outstanding $961 million aggregate 
principal amount of our 2019 Senior Notes, which payment consisted of the 102.976% redemption price plus all accrued and unpaid 
interest on the notes.  We financed the redemption with proceeds from the issuance of our 2026 Senior Notes and borrowings under our 
credit agreement.   

Repurchases of 2021 Senior Notes.  In September 2019, we paid $24 million to repurchase $25 million aggregate principal amount of 
the 2021 Senior Notes, which payment consisted of the average 94.708% purchase price plus all accrued and unpaid interest on the 
notes.  We financed the repurchases with cash and borrowings under our credit agreement. 

In October 2019, we paid an additional $72 million to repurchase $75 million aggregate principal  amount of the 2021 Senior Notes, 
which payment consisted of the average 95.467% purchase price plus all accrued and unpaid interest on the notes.  We financed the 
repurchases  with  borrowings  under  our  credit  agreement.    As  of  December 31,  2019,  $774  million  of  2021  Senior  Notes  remained 
outstanding.  

2020 Convertible Senior Notes.  In March 2015, we issued at par $1,250 million of 1.25% Convertible Senior Notes due April 1, 2020 
(the “2020 Convertible Senior Notes”).  During 2016, we exchanged $688 million aggregate principal amount of our 2020 Convertible 
Senior Notes for the same aggregate principal amount of new mandatory convertible senior notes.  Subsequently during 2016, all $688 
million aggregate principal amount of these mandatory convertible senior notes was converted into approximately 17.8 million shares 
of our common stock pursuant to the terms of the notes. 

In  September  2019,  we  paid  $299 million to  complete  a  cash  tender  offer  for  $300  million  aggregate  principal amount  of the  2020 
Convertible Senior Notes, which payment consisted of the 99.0% purchase price plus all accrued and unpaid interest on the notes and 
associated transaction costs.  We financed the tender offer with cash and borrowings under our credit agreement.  

The remaining $262 million aggregate principal amount of 2020 Convertible Senior Notes outstanding as of December 31, 2019 are 
convertible exclusively at the holder’s option.  Prior to January 1, 2020, the 2020 Convertible Senior Notes were convertible only upon 
the achievement of certain contingent market conditions.  As of December 31, 2019, none of the contingent market conditions allowing 
holders of the 2020 Convertible Senior Notes to convert these notes had been met.  On or after January 1, 2020, the 2020 Convertible 
Senior Notes are convertible at any time until the second scheduled trading day immediately preceding the April 1, 2020 maturity date 
of the notes.  The notes are convertible at a current conversion rate of 6.4102 shares of Whiting’s common stock per $1,000 principal 
amount  of the notes,  which is  equivalent to  a current conversion  price of  approximately  $156.00.  The  conversion  rate is  subject to 
adjustment in some events.  In addition, following certain corporate events that occur prior to the maturity date, we  will increase, in 
certain circumstances, the conversion rate for a holder who elects to convert its 2020 Convertible Senior Notes in connection with such 
corporate event.  We have the option to settle conversions of these notes with cash, shares of common  stock or a combination of cash 
and common  stock  at  our  election.    Our intent  is to  settle the  principal amount of  the  2020  Convertible  Senior  Notes in  cash  upon 
conversion.  At maturity, we must settle all outstanding 2020 Convertible Senior Notes in cash.  Our business plan includes the intent 
to settle the outstanding 2020 Convertible Senior Notes using borrowings under the credit agreement. 

Note  Covenants.    The  indentures  governing  the  Senior  Notes  restrict  us  from  incurring  additional  indebtedness,  subject  to  certain 
exceptions, unless  our  fixed  charge  coverage ratio  (as defined  in the indentures)  is  at  least 2.0 to  1.   If  we  were  in  violation  of this 
covenant,  then  we  may  not  be  able  to  incur  additional  indebtedness,  including  under  Whiting  Oil  and  Gas’  credit  agreement.  
Additionally, these indentures contain restrictive covenants that may limit our ability to, among other things, pay cash dividends, make 
certain  other  restricted  payments,  redeem  or  repurchase  our  capital  stock,  make  investments  or  issue  preferred  stock,  sell  assets, 
consolidate, merge or transfer all or substantially all of the assets of ours and our restricted subsidiaries taken as a whole, and enter into 
hedging contracts.  These covenants may potentially limit the discretion of our management in certain respects.  We were in compliance 

57 

with these  covenants as  of  December 31,  2019.    However, a  substantial  or extended  decline  in oil,  NGL  or  natural  gas  prices  may 
adversely affect our ability to comply with these covenants in the future. 

Shelf Registration Statement.  We have on file with the SEC a universal shelf-registration statement to allow us to offer an indeterminate 
amount of securities in the future.  Under the registration statement, we may periodically offer from time to time debt securities, common 
stock, preferred stock, warrants and other securities or any combination of such securities in amounts, prices and on terms announced 
when and if the securities are offered.  The specifics of any future offerings, along with the use  of proceeds of any securities offered, 
will be described in detail in a prospectus supplement at the time of any such offering. 

Contractual Obligations and Commitments 

Schedule of Contractual Obligations.  The following table summarizes our obligations and commitments as of December 31, 2019 to 
make future payments under certain contracts, aggregated by category of contractual obligation, for the time periods specified  below.  
This table does not include amounts payable under contracts where we cannot predict with accuracy the amount and timing of  such 
payments, including any amounts we may be obligated to pay under our derivative contracts, as such payments are dependent upon the 
price of crude oil in effect at the time of settlement, and any penalties that may be incurred for underdelivery under our physical delivery 
contracts.    For  further  information  on  these  contracts  refer  to  the  “Derivative  Financial  Instruments”  footnote  in  the  notes  to  the 
consolidated financial statements and “Delivery Commitments” in Item 2 of this Annual Report on Form 10-K.

(1)  Long-term debt consists of the outstanding principal amounts of the Senior Notes and the 2020 Convertible Senior Notes, as well 
as the outstanding borrowings under our credit agreement.  The credit agreement matures on April 12, 2023, provided that if at any 
time and for so long as any senior notes (other than the 2020 Convertible Senior Notes) have a maturity date prior to 91 days after 
April 12, 2023, the maturity date shall be the date that is 91 days prior to the maturity of such senior notes.  As of December 31, 
2019, we had $774 million aggregate principal amount of senior notes due March 15, 2021 and $408 million aggregate principal 
amount of senior notes due April 1, 2023.  Our business plan includes the intent to refinance certain senior notes, including our 
convertible senior notes due in 2020 and our senior notes due in 2021, as permitted by the September 13, 2019 amendment to the 
credit agreement.  Consequently, we have classified the credit agreement as long-term debt. 

(2)  Cash  interest  expense  on  the  Senior  Notes  is  estimated  assuming  no  further  principal  repayment  until  the  due  dates  of  the 
instruments.  Cash interest expense on the 2020 Convertible Senior Notes is estimated assuming no further principal repayments or 
conversions  prior to  maturity.  Cash interest  expense on  the credit agreement  is estimated  assuming  no  principal  borrowings  or 
repayments through the April 2023 instrument due date and a fixed interest rate of 3.9%.  Commitment fees on the credit agreement 
are estimated assuming no principal borrowings or repayments or changes to commitments through the April 2023 instrument due 
date. 

(3)  Asset  retirement  obligations  represent  the  present  value  of estimated amounts  expected  to  be  incurred  in the future  to plug  and 
abandon oil and gas wells, remediate oil and gas properties and dismantle their related plants, facilities and offshore platforms. 

(4)  We have a water disposal agreement which expires in 2024 under which we have contracted for the transportation and disposal of 
the produced water from our Redtail field.  Under the terms of the agreement, we are obligated to provide a minimum volume of 
produced  water  or else pay  for any  deficiencies at  the  price  stipulated  in the contract.   As  a  result of  our  reduced  development

operations at our Redtail field, we have made and expect to continue to make deficiency payments under this contract.  Refer to the 
“Commitments  and  Contingencies”  footnote  in  the  notes  to  the  consolidated  financial  statements  for  more  information  on  this 
contract and the related deficiency payments. 

(5)  We  have  operating  and  finance  leases  for  corporate  and  field  offices,  pipeline  and  midstream  facilities  and  automobiles.  The 
obligations reported above represent our minimum financial commitments pursuant to the terms of these contracts, however, our 
actual expenditures under these contracts may exceed the minimum commitments presented above.  Refer to the “Leases” footnote 
in the notes to the consolidated financial statements for more information on these leases.   

(6)  Our pipeline transportation agreements consist of contracts through 2024 with various third parties to facilitate the delivery of our 
produced oil, gas and NGLs to market.  These contracts require either fixed monthly reservation fees or commitments to deliver 
minimum volumes at fixed rates in exchange for dedicated pipeline capacity.  If minimum volume commitments are not met, we 
are required to pay any deficiencies at the prices stipulated in the contracts.  The obligations reported above represent our minimum 
financial commitments pursuant to the terms of these contracts, however, our actual expenditures under these contracts may exceed 
the minimum commitments presented above. 

(7)  We have one take-or-pay purchase agreement which expires in 2020, whereby we have committed to buy certain volumes of water 
for use in the fracture stimulation process on wells we complete in our Redtail field.  Under the terms of the agreement, we are 
obligated to purchase a minimum volume of water or else pay for any deficiencies at the prices stipulated in the contract.  As a 
result of our reduced development operations in this field, we have made and expect to continue to make deficiency payments under 
this contract.  Refer to the “Commitments and Contingencies” footnote in the notes to the consolidated financial statements for 
more information on this contract and the related deficiency payments. 

Based on current oil and natural gas prices and anticipated levels of production, we believe that the estimated net cash generated from 
operations,  together  with  cash  on hand and  amounts available  under  our  credit  agreement,  will be  adequate  to  meet  future  liquidity 
needs, including satisfying our financial obligations and funding our operating, development and exploration activities. 

New Accounting Pronouncements 

For  further  information  on  the  effects  of  recently  adopted  accounting  pronouncements  and  the  potential  effects  of  new  accounting 
pronouncements,  refer  to  the  “Summary  of  Significant  Accounting  Policies”  footnote  in  the  notes  to  the  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 statements in accordance with GAAP and SEC rules and regulations requires us to make certain 
assumptions and  estimates  that  affect the  reported amounts  of assets,  liabilities,  revenues  and expenses  as  well as  the disclosure of 
contingent assets and liabilities at the date of our financial statements.  We base our assumptions and estimates on historical experience 
and  other  sources  that  we  believe  to  be  reasonable  at  the  time.    Actual  results  may  vary  from  our  estimates  due  to  changes  in 
circumstances, weather, political environment, global economics, mechanical problems, general business conditions and other factors.  
A  summary  of  our  significant  accounting  policies  is  detailed  in  the  “Summary  of  Significant  Policies”  footnote  in  the  notes  to  the 
consolidated financial statements.  We have outlined below certain of these policies as being of particular importance to the portrayal 
of our financial position and results of operations and which require the application of significant judgment by our management. 

Successful Efforts Accounting.  We account for our oil and gas operations using the successful efforts method of accounting.  Under this 
method, the fair value of property acquired and all costs associated with successful exploratory wells and all development wells are 
capitalized.  Items charged to expense generally include geological and geophysical costs, costs of unsuccessful exploratory wells and 
oil and gas production costs.  All of our properties are located within the continental United States. 

Oil  and  Natural  Gas  Reserve  Quantities.    Reserve  quantities  and  the  related  estimates  of  future  net  cash  flows  affect  our  periodic 
calculations  of  depletion, impairment  of  our  oil  and natural  gas  properties and  our  asset  retirement  obligations.   Proved  oil  and  gas 
reserves are 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 

59 

evidence  indicates  that  renewal  is  reasonably  certain,  regardless  of  whether  deterministic  or  probabilistic  methods  are  used  for  the 
estimation.  Reserve quantities and future cash flows included in this report are prepared in accordance with guidelines established by 
the SEC and the FASB.  The accuracy of our reserve estimates is a function of  (i) the quality and quantity of available data,  (ii) the 
interpretation of that data, (iii) the accuracy of various mandated economic assumptions, and (iv) the judgments of the persons preparing 
the estimates. 

External petroleum engineers independently estimated all of the proved reserve quantities included in this Annual Report on Form 10-K.  
In  connection  with  our  external  petroleum  engineers  performing  their  independent  reserve  estimations,  we  furnish  them  with  the 
following  information  that  they  review:  (1) technical  support  data,  (2) technical  analysis  of  geologic  and  engineering  support 
information, (3) economic and  production  data,  (4) our  well  ownership  interests and  (5)  expected  future  development  activity.    The 
independent petroleum engineers, Cawley, Gillespie & Associates, Inc., evaluated 100% of our estimated proved reserve quantities and 
their related pre-tax future net cash flows as of  December 31, 2019.  Estimates prepared by others may be higher or lower than our 
estimates.   Because these estimates  depend  on  many  assumptions, all  of  which  may differ  substantially  from  actual  results,  reserve 
estimates may be different from the quantities of oil and gas that are ultimately recovered.  For example, if the crude oil and natural gas 
prices used in our year-end reserve estimates increased or decreased by 10%, our proved reserve quantities at December 31, 2019 would 
have increased by 9 MMBOE (2%) or decreased by 33 MMBOE (7%), respectively, and the pre-tax PV10% of our proved reserves 
would have increased by $0.9 billion (23%) or decreased by $0.8 billion (22%), respectively.  We continually make revisions to reserve 
estimates  throughout  the year  as  additional  information  becomes  available.    We  make  changes  to  depletion  rates  and  impairment 
calculations (when impairment indicators arise) in the same period that changes to reserve estimates are made. 

Depreciation, Depletion and Amortization.  Our rate of recording DD&A is dependent upon our estimates of total proved and proved 
developed reserves, which estimates incorporate various assumptions and future projections.  If our estimates of total proved or proved 
developed reserves decline, the rate at which we record DD&A expense increases, which in turn reduces our net income.  Such a decline 
in reserves may result from lower commodity prices or other changes to reserve estimates, as discussed above, and we are unable to 
predict  changes  in  reserve  quantity  estimates  as  such  quantities  are  dependent  on  the  success  of  our  exploration  and  development 
program, as well as future economic conditions. 

Impairment of Oil and Gas Properties.  We review the value of our oil and gas properties whenever management judges that events and 
circumstances indicate that the recorded carrying value of properties may not be recoverable.  Such events and circumstances include, 
but are not limited to, declines in commodity prices, increases in operating costs, unfavorable reserve revisions, poor well performance, 
changes in development plans and potential property divestitures.  Impairments of producing properties are determined by comparing 
their undiscounted future net cash flows to their net book values at the end of each period.  If a property’s net capitalized costs exceed 
undiscounted future net cash flows, the cost of the property is written down to “fair value,” which is determined using discounted future 
net  cash  flows  from  the  producing  property.    Different  pricing  assumptions  or  discount  rates  could  result  in  a  different  calculated 
impairment.  In addition to proved property impairments, we provide for impairments on significant undeveloped properties when we 
determine that the property will not be developed or a permanent impairment in value has occurred.  Individually insignificant unproved 
properties are amortized on a composite basis, based on past success, experience and average lease-term lives. 

Asset Retirement Obligation.  Our asset retirement obligations (“ARO”) consist of estimated future costs associated with the plugging 
and abandonment of oil and gas wells, removal of equipment and facilities from leased acreage and land restoration in accordance with 
applicable local, state and federal laws and the terms of our lease agreements.  The discounted fair value of an ARO liability is required 
to be recognized in the period in which it is incurred, with the associated asset retirement cost capitalized as part of the carrying cost of 
the oil and gas asset.  The recognition of an ARO requires that management make numerous assumptions regarding such factors as the 
estimated  probabilities,  amounts  and  timing  of  settlements;  the  credit-adjusted  risk-free  discount  rate;  the  inflation  rate;  and  future 
advances in technology.  In periods subsequent to the initial measurement of an ARO, we must recognize period-to-period changes in 
the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted 
cash flows.  Increases in the ARO liability due to the passage of time impact net income as accretion expense.  The related capitalized 
cost, including revisions thereto, is charged to expense through DD&A over the life of the oil and gas property. 

Derivative  Instruments.    All  derivative  instruments  are  recorded  in  the  consolidated  financial  statements  at  fair  value,  other  than 
derivative instruments that meet the “normal purchase normal sale” exclusion or other derivative scope exceptions.  We do not currently 
apply  hedge  accounting  to  any  of  our  outstanding  derivative  instruments,  and  as  a  result,  all  changes  in  derivative  fair  values  are 
recognized currently in earnings. 

60 

We determine the recorded amounts of our derivative instruments measured at fair value utilizing third-party valuation specialists.  We 
review these valuations, including the related model inputs and assumptions, and analyze changes in fair value measurements between 
periods.  We corroborate such inputs, calculations and fair value changes using various methodologies, and review unobservable inputs 
for reasonableness utilizing relevant information from other published sources.  When available, we utilize counterparty valuations to 
assess the reasonableness of our valuations.  The values we report in our financial statements change as the assumptions used in these 
valuations are revised to reflect changes in market conditions (particularly those for oil and natural gas futures) or other factors, many 
of which are beyond our control. 

We periodically enter into commodity derivative contracts to manage our exposure to oil and natural gas price volatility.  We primarily 
utilize costless collars and swaps which are generally placed with major financial institutions, as well as crude oil sales and delivery 
contracts.  We use hedging to help ensure that we have adequate funding for our capital programs and to manage returns on our drilling 
programs and acquisitions.  Our decision on the quantity and price at which we choose to hedge our production is based in part on our 
view of current and future market conditions.  While the use of these hedging arrangements limits the downside risk of adverse price 
movements, it may also limit future revenues from favorable price movements.  The use of hedging transactions also involves the risk 
that the counterparties will be unable to meet the financial terms of such transactions.  We evaluate the ability of our counterparties to 
perform at the inception of a hedging relationship and on a periodic basis as appropriate. 

We value our collars and swaps using industry-standard models that consider various assumptions, including quoted forward prices for 
commodities, time value, volatility factors and contractual prices for the underlying instruments, as well as  other relevant economic 
measures.    We  value  our  long-term  crude  oil  sales  and  delivery  contracts  based  on  a  probability-weighted  income  approach  which 
considers various assumptions, including quoted spot prices for commodities, market differentials for crude oil and U.S. Treasury rates.  
The discount rates used in the fair values of these instruments include a measure of nonperformance risk by the counterparty  or us, as 
appropriate. 

In  addition,  we  evaluate  the terms  of  our  convertible  debt and  other  contracts, if  any,  to  determine  whether  they  contain  embedded 
components that are required to be bifurcated and accounted for separately as derivative financial instruments. 

Income Taxes and Uncertain Tax Positions.  We provide for income taxes in accordance with FASB ASC Topic 740 – Income Taxes 
(“ASC 740”).  We record deferred tax assets and liabilities to account for the expected future tax consequences of events that have been 
recognized in our financial statements and our tax returns.  We routinely assess the realizability of our deferred tax assets.  If we conclude 
that it is more likely than not that some portion or all of our deferred tax assets will not be realized, the tax asset is reduced by a valuation 
allowance.  We consider future taxable income in making such assessments.  Numerous judgments and assumptions are inherent in the 
determination of future taxable income, including factors such as future operating conditions, particularly as they relate to prevailing oil 
and natural gas prices. 

On December 22, 2017, Congress passed the Tax Cuts and Jobs Act (the “TCJA”).  The new legislation significantly changed the U.S. 
corporate tax law by, among other things, lowering the U.S. corporate income tax rate from 35% to 21% beginning in  January 2018, 
implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries.  The SEC 
issued  Staff  Accounting Bulletin  No. 118 (“SAB 118”),  which allowed  registrants  to record provisional amounts  during  a  one-year 
“measurement period” similar to that used to account for business combinations, however, the measurement period was deemed to have 
ended earlier once the registrant had obtained, prepared and analyzed the information necessary to finalize its accounting.  During the 
measurement period, impacts of the law were to be recorded at the time a reasonable estimate for all or a portion of the effects could be 
made, and provisional amounts recognized and adjusted as information became available, prepared or analyzed.  As a result of the new 
legislation, we recognized the provisional impacts of the revaluation of our deferred tax assets and liabilities as of the date of enactment.  
We did not recognize any measurement period adjustments to these provisional amounts, and as of December 31, 2018, our accounting 
for the TCJA was complete.  

ASC 740 requires uncertain income tax positions to meet a more-likely-than-not realization threshold to be recognized in the financial 
statements.    Under  ASC  740,  uncertain  tax  positions  that  previously  failed  to  meet  the  more-likely-than-not  threshold  should  be 
recognized in the first subsequent financial reporting period in which that threshold is met.  Previously recognized uncertain tax positions 
that no longer meet the more-likely-than-not threshold should be derecognized in the first subsequent financial reporting period in which 
that threshold is no longer met. 

We  are  subject  to  taxation  in many  jurisdictions,  and the  calculation  of  our  tax liabilities  involves  dealing  with  uncertainties  in  the 
application of complex tax laws and regulations in various taxing jurisdictions.  If we ultimately determine that the payment of these 

61 

liabilities will be unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine the liability 
no longer applies.  Conversely, we record additional tax charges in a period in which we determine that a recorded tax liability is less 
than we expect the ultimate assessment to be. 

Revenue  Recognition.    We  predominantly  derive  our  revenue  from  the  sale  of  produced  oil,  NGLs  and  natural  gas.    Revenue  is 
recognized when we meet our performance obligation to deliver  the product and control is transferred to the customer.   We receive 
payment  for  product  sales  from  one  to  three  months  after  delivery.    At  the  end  of  each  month  when  the  performance  obligation  is 
satisfied, the amount of production delivered and the price we will receive can be reasonably estimated and amounts due from customers 
are accrued in accounts receivable trade, net in the consolidated balance sheets.  Variances between our estimated revenue and actual 
payments are recorded in the month the payment is received.  However, differences have been and are insignificant. 

Accounting for Business Combinations.  We account for business combinations using the acquisition method, which is the only method 
permitted under FASB ASC Topic 805 – Business Combinations, and involves the use of significant judgment. 

Under the acquisition method of accounting, a business combination is accounted for at a purchase price based upon the fair value of 
the consideration given.  The assets and liabilities acquired are measured at their fair values, and the purchase price is allocated to the 
assets and liabilities based upon these fair values.  The excess, if any, of the consideration given to acquire an entity over the net amounts 
assigned to its assets acquired and liabilities assumed is recognized as goodwill.  The excess, if any, of the fair value of assets acquired 
and liabilities assumed over the cost of an acquired entity is recognized immediately to earnings as a gain from bargain purchase. 

Determining the fair values of the assets and liabilities acquired involves the use of judgment, since some of the assets and liabilities 
acquired do not have fair values that are readily determinable.  Different techniques may be used to determine fair values, including 
market prices (where available), appraisals, comparisons to transactions for similar assets and liabilities, and present values of estimated 
future cash flows, among others.  Since these estimates involve the use of significant judgment, they can change as new information 
becomes available. 

The business combinations completed during the prior three years consisted of oil and gas properties.  In general, the consideration we 
have paid to acquire these properties or companies was entirely allocated to the fair value of the assets acquired and liabilities assumed 
at  the  time  of  acquisition  and  consequently,  there  was  no  goodwill  nor  any  bargain  purchase  gains  recognized  on  our  business 
combinations. 

Leases.    We  have  operating  and  finance  leases  for  corporate  and  field  offices,  pipeline  and  midstream  facilities,  field  and  office 
equipment  and  automobiles.    Right-of-use  (“ROU”)  assets  and  liabilities  associated  with  these  leases  are  recognized  at  the  lease 
commencement date based on the present value of the lease payments over the lease term.   ROU assets represent our right to use an 
underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments.   

Operating lease cost is recognized on a straight-line basis over the lease term.  Finance lease cost is recognized based on the effective 
interest method for the lease liability and straight-line amortization of the ROU asset, resulting in more cost being recognized in earlier 
lease  periods.    All  payments  for  short-term  leases,  including  leases  with  a  term  of  one  month  or  less,  are  recognized  in  income  or 
capitalized to the cost of oil and gas properties on a straight-line basis over the lease term.  Additionally, any variable payments, which 
are generally related to the corresponding utilization of the asset, are recognized in the period in which the obligation was incurred.   

We adopted FASB ASC Topic 842 – Leases effective January 1, 2019 using the modified retrospective approach.  Refer to the “Summary 
of Significant Accounting Policies” and “Leases” footnotes in the notes to the consolidated financial statements for more information 
on this new accounting standard.  

Effects of Inflation and Pricing 

As commodity prices have begun to recover from previous lows during 2018 and 2019, the cost of oil field goods and services has also 
risen.  The oil and gas industry is very cyclical, and the demand for goods and services  of oil field companies, suppliers and others 
associated with the industry puts extreme pressure on the economic stability and pricing structure within the industry.  Typically, as 
prices for oil and natural gas increase, so do all associated costs.  Conversely, in a period of declining prices, associated cost declines 
are likely to lag and not adjust downward in proportion to prices.  Material changes in prices also impact our current revenue stream, 
estimates of future reserves, borrowing base calculations of our credit agreement, depletion expense, impairment assessments of oil and 
gas properties and values of properties in purchase and sale transactions.  Material changes in prices can impact the value of oil and gas 

62 

companies and their ability to raise capital, borrow money and retain personnel.  While we do not currently expect business costs to 
materially  increase  in  the  near  term,  higher  demand  in  the  industry  could  result  in  increases  in  the  costs  of  materials,  services  and 
personnel. 

Forward-Looking Statements 

This report contains statements that we believe to be “forward-looking statements” within the meaning of Section 27A of the Securities 
Act  of  1933  and  Section 21E  of the  Securities Exchange  Act  of  1934.   All  statements  other  than  historical  facts,  including,  without 
limitation, statements regarding our future financial position, business strategy, projected revenues, earnings, costs, capital expenditures

Item 7A.      Quantitative and Qualitative Disclosures about Market Risk 

Commodity Price Risk 

The price we receive for our oil and gas production heavily influences our revenue,  profitability, access to capital and future rate of 
growth.  Crude oil and natural gas are commodities, and therefore, their prices are subject to wide fluctuations in response to relatively 
minor changes in supply and demand.  Historically, the markets for oil and gas have been volatile, and these markets will likely continue 
to be volatile in the future.   

We periodically enter into derivative contracts to achieve a more predictable cash flow by reducing our exposure to oil and natural gas 
price volatility.  Our derivative contracts have traditionally been costless collars and swaps, although we evaluate and have entered into 
other forms of derivative instruments as well.  Currently, we do not apply hedge accounting, and therefore all changes in commodity 
derivative fair values are recorded immediately to earnings. 

Crude Oil Collars, Swaps and Options.  Our hedging portfolio currently consists of collars, swaps and options.  Refer to the “Derivative 
Financial  Instruments”  footnote  in  the  notes  to  the  consolidated  financial  statements  for  a  description  and  list  of  our  outstanding 
derivative contracts at December 31, 2019, as well as derivative contracts established subsequent to that date. 

Our collars and options have the effect of providing a protective floor while allowing us to share in upward pricing movements.  The 
fair value of our crude oil collars and options at December 31, 2019 was a net liability of $3 million.  A hypothetical upward or downward 
shift of 10% per Bbl in the NYMEX forward curve for crude oil as of December 31, 2019 would cause an increase of $26 million or a 
decrease of $19 million, respectively, in this fair value liability. 

Our  swap  contracts  entitle us  to  receive  settlement  from  the  counterparty in  amounts, if any,  by  which the  settlement  price  for the 
applicable calculation period is less than the fixed price, or to pay the counterparty if the settlement price for the applicable calculation 
period is more than the fixed price.  The fair value of our swaps at December 31, 2019 was a net liability of $7 million.  A hypothetical 
upward or downward shift of 10% per Bbl in the NYMEX forward curve for crude oil as of December 31, 2019 would cause an increase 
or decrease, respectively, of $29 million in this fair value liability. 

While these collars, options and fixed-price swaps are designed to decrease our exposure to downward price movements, they also have 
the effect of limiting the benefit of price increases above the ceiling with respect to the hedges and options and upward price movements 
generally with respect to the fixed-price swaps. 

Interest Rate Risk 

Market  risk is  estimated  as the change  in  fair value  resulting  from a  hypothetical  100  basis  point  change in the  interest  rate  on  the 
outstanding balance under our credit agreement.  Our credit agreement allows us to fix the interest rate for all or a portion of the principal 
balance for a period up to six months.  To the extent that the interest rate is fixed, interest rate changes affect the instrument’s fair market 
value but do not impact results of operations or cash flows.  Conversely, for the portion of the credit agreement that has a floating interest 
rate,  interest  rate  changes  will  not  affect  the  fair  market  value  but  will  impact  future  results  of  operations  and  cash  flows.    At 
December 31, 2019, our outstanding principal balance under our credit agreement was $375 million, and the weighted average interest 
rate  on  the  outstanding  principal  balance  was  3.3%.    At  December  31,  2019,  the  carrying  amount  approximated  fair  market  value.  
Assuming a constant debt level of $375 million, the cash flow impact resulting from a 100 basis point change in interest rates during 
periods when the interest rate is not fixed would be $4 million over a 12-month time period.  Changes in interest rates do not affect the 
amount of interest we pay on our fixed-rate senior notes, but changes in interest rates do affect the fair values of these notes. 

The interest rate on our 2020 Convertible Senior Notes is fixed at 1.25%, and as such, we are not subject to any direct risk of loss related 
to fluctuations in interest rates.  However, changes in interest rates do affect the fair value of this debt instrument, which could impact 
the amount of gain or loss that we recognize in earnings upon conversion of the notes.  Refer to the “Long-Term Debt” and “Fair Value 
Measurements” footnotes in the notes to the consolidated financial statements for more information on the material terms and fair values 
of the 2020 Convertible Senior Notes.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of 
Whiting Petroleum Corporation 
Denver, Colorado 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Whiting Petroleum Corporation and subsidiaries (the "Company") 
as of December 31, 2019 and 2018, the related consolidated statements of operations, cash flows and equity for each of the three years 
in the period ended December 31, 2019, and the related notes (collectively referred to as the "financial statements").  In our opinion, the 
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, 
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with 
accounting principles generally accepted in the United States of America. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), 
the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control — 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated 
February 27, 2020, expressed an unqualified opinion on the Company's internal control over financial reporting. 

Basis for Opinion 

These  financial  statements  are  the  responsibility  of  the  Company's  management.  Our  responsibility  is  to  express  an  opinion  on  the 
Company's financial statements based on our audits.  We are a public accounting firm registered with the PCAOB and are required to 
be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations 
of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.  
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error 
or fraud, and performing procedures that respond to those risks.  Such procedures included examining, on a test basis, evidence regarding 
the  amounts  and  disclosures  in  the  financial  statements.    Our  audits  also  included  evaluating  the  accounting  principles  used  and 
significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that 
our audits provide a reasonable basis for our opinion. 

Critical Audit Matter 

The  critical audit matter communicated below  is a matter arising from  the current-period audit of  the financial  statements that  was 
communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to 
the financial statements and (2) involved our especially challenging, subjective, or complex judgments.  The communication of critical 
audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the 
critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. 

Proved Oil and Natural Gas Property Depletion – Oil and Natural Gas Reserve Quantities – Refer to Notes 1, 2 and 8 to the financial 
statements 

Critical Audit Matter Description 

The Company’s proved oil and natural gas properties are depleted using the units of production method and are evaluated for impairment 
by comparison to the future net cash flows of the underlying oil and natural gas reserves.  The development of the Company’s oil and 
natural gas reserve quantities and the related future net cash flows requires management to make significant estimates and assumptions 
related to the five-year development rule for proved undeveloped reserves and future oil and natural gas prices.  The Company engages 
an independent reserve engineer to estimate oil and natural gas quantities using these estimates and assumptions and engineering data.  
Changes in these assumptions or engineering data could have a significant impact on the amount  of depletion and any proved oil and 
gas impairment.  The proved oil and gas properties balance was $7 billion, as of December 31, 2019, net of accumulated depreciation, 

66 

depletion and amortization.  Depreciation, depletion and amortization expense was $816 million for the year ended December 31, 2019.  
No impairment was recognized during 2019. 

Given  the  significant judgments made  by management,  performing audit  procedures  to  evaluate the  Company’s  oil and  natural  gas 
reserve quantities and the related net cash flows including management’s estimates and assumptions related to the five-year development 
rule and future oil and natural gas prices, required a high degree of auditor judgment and an increased extent of effort, including the 
need to involve our fair value specialists. 

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to management’s significant judgments and assumptions related to oil and natural gas reserves quantities 
and estimates of the future net cash flows included the following, among others: 

•  We tested the operating effectiveness of controls related to the Company’s estimation of oil and natural gas reserve quantities 
and the related future net cash flows, including controls relating to the five-year development plan and future oil and natural 
gas prices. 

•  We evaluated the reasonableness of management’s five-year development plan by comparing the forecasts to: 

-  Historical conversions of proved undeveloped oil and natural gas reserves into proved developed oil and natural gas 

reserves 

- 

Internal communications to management and the Board of Directors 

-  Permits and approval for expenditures  

-  Forecasted information by basin included in Company press releases as well as in analyst and industry reports for the 

Company and certain of its peer companies  

•  With the assistance of our fair value specialists, we evaluated management’s estimated future sales prices for oil and natural 

gas, by:  

-  Understanding  the  methodology  used  by  management  for  development  of  the  future  prices  and  comparing  the 

estimated prices to an independently determined range of prices 

-  Comparing management’s estimates to published forward pricing indices and third-party industry sources 

-  Evaluating the historical realized price differentials incorporated in the future oil and natural gas prices 

-  Evaluating  the  experience,  qualifications  and  objectivity  of  management’s  expert,  an  independent  reservoir 

engineering firm, including performing analytical procedures on the reserve quantities

WHITING PETROLEUM CORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.         SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Description of Operations—Whiting Petroleum Corporation, a Delaware corporation, is an independent oil and gas company engaged 
in the development, production, acquisition and exploration of crude oil, NGLs and natural gas primarily in the Rocky Mountains region 
of the United States.  Unless otherwise specified or the context otherwise requires, all references in these notes to “Whiting” or the 
“Company” are to Whiting Petroleum Corporation and its consolidated subsidiaries, Whiting Oil and Gas Corporation (“Whiting Oil 
and Gas”), Whiting US Holding Company, Whiting Canadian Holding Company ULC, Whiting Resources Corporation and Whiting 
Programs, Inc. 

Basis of Presentation of Consolidated Financial Statements—The consolidated financial statements have been prepared in accordance 
with GAAP and SEC rules and regulations and include the accounts of Whiting Petroleum Corporation and its consolidated subsidiaries.   
Investments in entities which give Whiting significant influence, but not control, over the investee are accounted for using  the equity 
method.  Under the equity method, investments are stated at cost plus the Company’s equity in undistributed earnings and losses.  All 
intercompany balances and transactions have been eliminated upon consolidation. 

Use  of  Estimates—The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and 
assumptions that affect the reported amounts of assets and liabilities, the 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.  Items subject to such estimates 
and  assumptions  include  (i) oil  and  natural  gas  reserves;  (ii) impairment  tests  of  long-lived  assets;  (iii) depreciation,  depletion  and 
amortization; (iv) asset retirement obligations; (v) assignment of fair value and allocation of purchase price in connection with business 
combinations,  including  the  determination  of  any  resulting  goodwill;  (vi) income  taxes;  (vii) accrued  liabilities;  (viii) valuation  of 
derivative instruments; and (ix) accrued revenue and related receivables.  Although management believes these estimates are reasonable, 
actual results could differ from these estimates.  Further, these estimates and other factors, including those outside of the Company’s 
control, such as the impact of lower commodity prices, may have a significant negative impact to the Company’s business, financial 
condition, results of operations and cash flows. 

Cash  and  Cash  Equivalents—Cash  equivalents  consist  of  demand  deposits  and  highly  liquid  investments  which  have  an  original 
maturity of three months or less. 

Accounts Receivable Trade—Whiting’s accounts receivable trade consist mainly of receivables from oil and gas purchasers and joint 
interest owners on properties the Company operates.  For receivables from joint interest owners, Whiting typically has the ability to 
withhold future revenue disbursements to recover any non-payment of joint interest billings.  Generally, the Company’s oil and gas 
receivables are collected within two months, and to date, the Company has had minimal bad debts. 

The  Company  routinely  assesses  the  recoverability  of  all  material  trade  and  other  receivables  to  determine  their  collectability.    At 
December 31, 2019 and 2018, the Company had an allowance for doubtful accounts of $9 million and $12 million, respectively. 

Inventories—Materials  and  supplies  inventories  consist  primarily  of  tubular  goods  and  production  equipment,  carried  at  weighted-
average  cost.    Materials  and  supplies  are  included  in  other  property  and  equipment  and  totaled  $39  million  and  $23  million  as  of 
December 31, 2019 and 2018, respectively.  Crude oil in tanks inventory is carried at the lower of the estimated cost to produce or net 
realizable value.  Oil in tanks is included in prepaid expenses and other and totaled $6 million and $5 million as of December 31, 2019 
and 2018, respectively. 

Oil and Gas Properties 

Proved.    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 development costs are capitalized when incurred and depleted on a unit-of-production 
basis over the remaining life of proved reserves and proved developed reserves, respectively.  Costs of drilling exploratory  wells are 
initially capitalized but are charged to expense if the well is determined to be unsuccessful. 

The Company assesses its proved oil and gas properties for impairment whenever events or circumstances indicate that the carrying 
value  of  the assets may  not  be  recoverable.   Such events  include,  but  are  not limited  to,  declines in commodity prices,  increases  in 

73 

operating costs, unfavorable reserve revisions, poor well performance, changes in development plans and potential property divestitures.  
The impairment test compares undiscounted future net cash flows to the assets’ net book value.   These undiscounted cash flows are 
driven by significant assumptions, including the Company’s expected future development activity, reserve estimates, forecasted pricing, 
future operating costs, capital expenditures and severance taxes.  If the net capitalized costs exceed undiscounted future net cash flows, 
then the cost of the property is written down to fair value utilizing a discounted future net cash flow analysis.   

Impairment expense for proved properties totaled $835 million for the year ended December 31, 2017, which is reported in exploration 
and impairment expense. 

Net carrying values of retired, sold or abandoned properties that constitute less than a complete unit of depreciable property are charged 
or credited, net of proceeds, to accumulated depreciation, depletion and amortization unless doing so significantly affects the unit-of-
production amortization rate, in which case a gain or loss is recognized in income.  Gains or losses from the disposal of complete units 
of depreciable property are recognized to earnings. 

Unproved.  Unproved properties consist of costs to acquire undeveloped leases as well as purchases of unproved reserves.  Undeveloped 
lease costs and  unproved  reserve  acquisitions are  capitalized, and individually  insignificant  unproved  properties  are amortized on a 
composite basis, based on average lease-term lives and the historical experience of developing acreage in a particular prospect.  The 
Company  evaluates  significant  unproved  properties  for  impairment  based  on  remaining  lease  term,  drilling  results,  reservoir 
performance, seismic interpretation or future plans to develop acreage.  When successful wells are drilled on undeveloped leaseholds, 
unproved  property  costs  are  reclassified  to  proved  properties  and  depleted  on  a  unit-of-production  basis.    Impairment  expense  for 
unproved  properties  totaled  $9  million,  $37  million  and  $59  million  for  the years  ended  December 31,  2019,  2018  and  2017, 
respectively, which is reported in exploration and impairment expense. 

Exploratory.  Geological and geophysical costs, including exploratory seismic studies, and the costs of carrying and retaining unproved 
acreage are expensed as incurred.  Costs of seismic studies that are utilized in development drilling within an area of proved reserves 
are capitalized as development costs.  Amounts of seismic costs capitalized are based on only those blocks of data used in determining 
development well locations.  To the extent that a seismic project covers areas of both developmental and exploratory drilling, those 
seismic costs are proportionately allocated between development costs and exploration expense. 

Costs of drilling exploratory wells are initially capitalized, pending determination of whether the well has found proved reserves.  If an 
exploratory well has not found proved reserves, the costs of drilling the well and other associated costs are charged to expense.  Costs 
incurred for exploratory wells that find reserves, which cannot yet be classified as proved, continue to be capitalized if (i) the well has 
found a sufficient quantity of reserves to justify completion as a producing well and (ii) the Company is making sufficient progress 
assessing the reserves and the economic and operating viability of the project.  If either condition is not met, or if the Company obtains 
information that raises substantial doubt about the economic or operational viability of the project, the exploratory well costs, net of any 
salvage value, are expensed. 

Other Property  and  Equipment—Other  property and  equipment consists  of materials and  supplies  inventories, carried  at  weighted-
average  cost,  and  furniture  and  fixtures,  buildings  and  leasehold  improvements,  which  are  stated  at  cost  and  depreciated  using  the 
straight-line method over their estimated useful lives ranging from 4 to 30 years.  Additionally, other property and equipment includes 
finance lease right-of-use assets for pipeline and midstream facilities, field and office equipment and automobiles, which are depreciated 
using the straight-line method over their estimated useful lives ranging from 5 to 30 years.  Refer to the “Leases” footnote for additional 
information on these lease assets. 

Debt Issuance Costs—Debt issuance costs related to the Company’s senior notes and convertible senior notes are included as a deduction 
from the carrying amount of long-term debt in the consolidated balance sheets and are amortized to interest expense using the effective 
interest method over the term of the related debt.  Debt issuance costs related to the credit facility are included in other long-term assets 
and are amortized to interest expense on a straight-line basis over the term of the agreement. 

Debt Discounts and Premiums—Debt discounts and premiums related to the Company’s senior notes and convertible senior notes are 
included  as  a  deduction  from  or  addition  to  the  carrying  amount  of  the  long-term  debt  in  the  consolidated  balance  sheets  and  are 
amortized to interest expense using the effective interest method over the term of the related notes. 

Derivative Instruments—The Company enters into derivative contracts, primarily collars, swaps and options, to manage its exposure 
to commodity price risk.  Whiting follows FASB ASC Topic 815  – Derivatives and Hedging, to account for its derivative financial 

74 

instruments.  All derivative instruments, other than those that meet the “normal purchase normal sale” exclusion, are recorded on the 
balance  sheet  as  either  an  asset  or  liability  measured  at  fair  value.    Gains  and  losses  from  changes  in  the  fair  value  of  derivative 
instruments are recognized immediately in earnings, unless the derivative meets specific hedge accounting criteria and the derivative 
has  been  designated  as  a  hedge.    The  Company  does  not  currently  apply  hedge  accounting  to  any  of  its  outstanding  derivative 
instruments, and as a result, all changes in derivative fair values are recognized currently in earnings. 

Cash flows from derivatives used to manage commodity price risk are classified in operating activities along with the cash flows of the 
underlying hedged transactions.  The Company does not enter into derivative instruments for speculative or trading purposes.  Refer to 
the “Derivative Financial Instruments” footnote for further information. 

Asset  Retirement  Obligations  and  Environmental  Costs—Asset  retirement  obligations  relate  to  future  costs  associated  with  the 
plugging and abandonment of oil and gas wells, removal of equipment and facilities from leased acreage and returning such land to its 
original condition.  The Company follows FASB ASC Topic 410 – Asset Retirement and Environmental Obligations, to determine its 
asset retirement obligation amounts by calculating the present value of the estimated future cash outflows associated with its plug and 
abandonment obligations.  The fair value of a liability for an asset retirement obligation is recorded in the period in which it is incurred 
(typically when a well is completed or acquired or when an asset is installed at the production location), and the cost of such liability 
increases the carrying amount of the related long-lived asset by the same amount.  The liability is accreted each period through charges 
to depreciation, depletion and amortization expense, and the capitalized cost is depleted on a unit-of-production basis over the proved 
developed reserves of the related asset.  Revisions typically 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,  and  such  revisions  result  in 
adjustments to the related capitalized asset and corresponding liability. 

Liabilities for environmental costs are recorded on an undiscounted basis when it is probable that obligations have been incurred and 
the amounts can be reasonably estimated.  These liabilities are not reduced by possible recoveries from third parties. 

Deferred Gain on Sale—The deferred gain on sale relates to the sale of 18,400,000 Whiting USA Trust II (“Trust II”) units, and is 
amortized to income based on the unit-of-production method. 

Revenue  Recognition—Revenues  are  predominantly  derived  from  the  sale  of  produced  oil,  NGLs  and  natural  gas.    The  Company 
accounts for revenues in accordance with FASB ASC Topic 606 – Revenue from Contracts with Customers, and thus oil and gas revenues 
are recognized when the performance obligation to deliver the product is met and control is transferred to the customer.  Payments for 
product sales are received one to three months after delivery.  At the end of each month  when the performance obligation is satisfied 
and the amount of production delivered and the price received can be reasonably estimated, amounts due from customers are accrued in 
accounts receivable trade, net in the consolidated balance sheets.  Variances between estimated revenue and actual payments are recorded 
in the month the payment is received.  However, differences have been and are insignificant. 

Taxes collected and remitted to governmental agencies on behalf of customers are not included in revenues or costs and expenses. 

General and Administrative Expenses—General and administrative expenses are reported net of reimbursements of overhead costs that 
are allocated to the working interest owners that participate in oil and gas properties operated by Whiting. 

Stock-based Compensation Expense—The Company has share-based employee compensation plans that provide for the issuance of 
various types of stock-based awards, including shares of restricted stock, restricted stock units, performance shares, performance share 
units and stock options, to employees and non-employee directors.  The Company determines compensation expense for share-settled 
awards granted under these plans based on the grant date fair value, and such expense is recognized on a straight-line basis over the 
requisite  service  period  of  the  award.   The  Company determines compensation  expense  for  cash-settled awards  granted  under  these 
plans based on the fair value of such awards at the end of each reporting period.  Cash-settled awards are recorded as a liability in the 
consolidated balance sheets, and gains and losses from changes in fair value are recognized immediately in earnings.  The Company 
accounts for forfeitures of share-based awards as they occur.  Refer to the “Stock-Based Compensation” footnote for further information. 

401(k) Plan—The Company has a defined contribution retirement plan for all employees.  The plan is funded by employee contributions 
and discretionary  Company contributions.   The  Company’s  contributions for  2019, 2018  and  2017  were  $7 million,  $7  million and 
$8 million, respectively.  Employees vest in employer contributions at 20% per year of completed service up to five years. 

75 

Acquisition Costs—Acquisition related expenses, which consist of external costs directly related to the Company’s acquisitions, such 
as advisory, legal, accounting, valuation and other professional fees, are expensed as incurred. 

Maintenance and Repairs—Maintenance and repair costs that do not extend the useful lives of property and equipment are charged to 
expense as incurred.  Major replacements, renewals and betterments are capitalized. 

Income Taxes—Income taxes are recognized based on earnings reported for tax return purposes in addition to a provision for deferred 
income taxes.  Deferred income taxes are accounted for using the liability method.  Under this method, deferred tax assets and liabilities 
are  determined  by  applying  the  enacted  statutory  tax  rates  in  effect  at  the  end  of  a  reporting  period  to  the  cumulative  temporary 
differences between the tax bases of assets and liabilities and their reported amounts in the Company’s financial statements.  The effect 
on deferred taxes for a change in tax rates is recognized in income in the period that includes the enactment date.  A valuation allowance 
for deferred tax assets is established when it is more likely than not that some portion of the benefit from deferred tax assets will not be 
realized.   The  Company’s  uncertain tax  positions must  meet a more-likely-than-not  realization  threshold  to  be  recognized, and  any 
potential accrued interest and penalties related to unrecognized tax benefits are recognized within income tax expense. 

Earnings Per Share—Basic earnings per common share is calculated by dividing net income attributable to common shareholders by 
the weighted average number of common shares outstanding during each period.  Diluted earnings per common share is calculated by 
dividing  adjusted  net  income  attributable  to  common  shareholders  by  the  weighted  average  number  of  diluted  common  shares 
outstanding, which includes the effect of potentially dilutive securities.  Potentially dilutive securities for the diluted earnings per share 
calculations consist of unvested restricted and performance stock awards and units, outstanding stock options and contingently issuable 
shares of convertible debt to be settled in cash, all using the treasury stock method.  When a loss from continuing operations exists, all 
dilutive securities and potentially dilutive securities are anti-dilutive and are therefore excluded from the computation of diluted earnings 
per share. 

Industry Segment and Geographic Information—The Company has evaluated how it is organized and managed and has identified only 
one  operating  segment,  which  is  the  exploration  and  production  of  crude  oil,  NGLs  and  natural  gas.    The  Company  considers  its 
gathering, processing and marketing functions as ancillary to its oil and gas producing activities.  All of the Company’s operations and 
assets are located in the United States, and substantially all of its revenues are attributable to United States customers. 

Concentration of Credit Risk—Whiting is exposed to credit risk in the event of nonpayment by counterparties, a significant portion of 
which are concentrated in energy related industries.  The creditworthiness of customers and other counterparties is subject to continuing 
review.  The following tables present the percentages by purchaser that accounted for 10% or more of the Company’s total oil, NGL 
and natural gas sales for the years ended December 31, 2019, 2018 and 2017.

Adopted and Recently Issued Accounting Pronouncements—In February 2016, the FASB issued Accounting Standards Update No. 
2016-02, Leases (“ASU 2016-02”).  The objective of this ASU is to increase transparency and comparability among organizations by 
recognizing lease assets  and  liabilities  on the  balance  sheet and  disclosing  key  information about  leasing  arrangements.   The  FASB 
subsequently issued various ASUs which provided additional implementation guidance, and these ASUs collectively make up FASB

ASC Topic 842 – Leases (“ASC 842”).  ASC 842 is effective for fiscal years, and interim periods within those fiscal years, beginning 
after December 15, 2018.  The standard permits retrospective application through recognition of a cumulative-effect adjustment at the 
beginning of either the earliest reporting period presented or the period of adoption.  The Company adopted ASC 842 effective January 1, 
2019 using the modified retrospective method as of the adoption date.  Whiting has completed the assessment of its existing accounting 
policies and documentation, implementation of lease accounting software and enhancement of its internal controls.  Adoption of the 
standard resulted in the recognition of additional lease assets and liabilities on Whiting’s consolidated balance sheet as well as additional 
disclosures.  The adoption did not have a material impact to the Company’s consolidated statement of operations.  Refer to the “Leases” 
footnote for further information on the Company’s implementation of this standard.

County, North Dakota and its 50% interest in the Belfield gas processing plant located in Stark County, North Dakota, as well as the 
associated natural gas, crude oil and water gathering systems, effective January 1, 2017, for aggregate sales proceeds of $375 million 
(before closing adjustments).  The Company used the net proceeds from this transaction to repay a portion of the debt outstanding under 
its credit agreement. 

On September 1, 2017, the Company completed the sale of its interests in certain producing oil and gas properties located in the Fort 
Berthold Indian Reservation area in Dunn and McLean counties of North Dakota, as well as other related assets and liabilities, (the

and resulted in a pre-tax loss on sale of $402 million.  The Company used the net proceeds from the sale to repay a portion of the debt 
outstanding under its credit agreement. 

There were no significant acquisitions during the year ended December 31, 2017. 

4.        LEASES  

The Company adopted ASC 842 effective January 1, 2019, which replaces previous lease accounting requirements under FASB ASC 
Topic 840 – Leases (“ASC 840”).  The standard was adopted using the modified retrospective approach which resulted in the recognition 
of approximately $30 million and $36 million of additional lease assets and liabilities, respectively, on the consolidated balance sheet 
upon adoption.  The Company has elected certain practical expedients available under ASC 842 including those that permit the Company 
to  not  (i)  reassess  prior conclusions  reached  under  ASC  840  for  lease  identification,  lease  classification and initial  direct  costs,  (ii) 
evaluate existing or expired land easements under the new standard and (iii) separate lease and non-lease components contained within 
a  single  agreement  for  all  classes  of  underlying  assets.    Accordingly,  the  adoption  of  the  standard  did  not  result  in  the  Company 
recognizing a cumulative-effect adjustment to retained earnings.  Additionally, the Company has elected the short-term lease recognition 
exemption for all classes of underlying assets, and therefore, leases with a term of one year or less have not and will not be recognized 
on the consolidated balance sheets.   

The Company has operating and finance leases for corporate and field offices, pipeline and midstream facilities and automobiles.  Right-
of-use (“ROU”) assets and liabilities associated with these leases are recognized at the lease commencement date based on the present 
value of the lease payments over the lease term.  ROU assets represent the Company’s right to use an underlying asset for the lease term, 
and lease liabilities represent the Company’s obligation to make lease payments.

The Company’s leases have remaining terms of less than one year to 10 years.  Most of the Company’s leases do not state or imply a 
discount rate.  Accordingly, the Company uses its incremental borrowing rate based on information available at lease commencement 
to  determine  the  present  value  of  the  lease  payments.    Information  regarding  the  Company’s  lease  terms  and  discount  rates  as  of 
December 31, 2019 is as follows:

Operating lease cost is recognized on a straight-line basis over the lease term.  Finance lease cost is recognized based on the effective 
interest method for the lease liability and straight-line amortization of the ROU asset, resulting in more cost being recognized in earlier 
lease  periods.    All  payments  for  short-term  leases,  including  leases  with  a  term  of  one  month  or  less,  are  recognized  in  income  or 
capitalized to the cost of oil and gas properties on a straight-line basis over the lease term.  Additionally, any variable payments, which 
are generally related to the corresponding utilization of the asset, are recognized in the period in which the obligation was incurred.

Whiting Oil and Gas, the Company’s wholly owned subsidiary, has a credit agreement with a syndicate of banks that as of December 31, 
2019 had a borrowing base of $2.05 billion and aggregate commitments of $1.75 billion.  As of December 31, 2019, the Company had 
$1.4 billion of available borrowing capacity under the credit agreement, which was net of $375 million of borrowings outstanding and 
$2 million in letters of credit outstanding. 

The  borrowing  base  under  the  credit  agreement  is  determined  at  the  discretion  of  the  lenders,  based  on  the  collateral  value  of  the 
Company’s  proved  reserves  that  have  been  mortgaged  to  such  lenders,  and  is  subject  to  regular  redeterminations  on  May 1  and 
November 1 of each year, as well as special redeterminations described in the credit agreement, in each case which may reduce the 
amount of the borrowing base.  Upon a redetermination of the borrowing base, either on a periodic or special redetermination date, if 
total  outstanding  credit  exposure  exceeds  the  redetermined  borrowing  base,  the  Company  will  be  required  to  prepay  outstanding 
borrowings in an aggregate principal amount equal to such excess in six substantially equal monthly installments.  In October 2019, the 
borrowing base under the credit agreement was reduced from $2.25 billion to $2.05 billion in connection with the semi-annual regular 
borrowing base redetermination, with no change to the aggregate commitments of $1.75 billion. 

A portion of the revolving credit facility in an aggregate amount not to exceed $50 million may be used to issue letters of credit for the 
account of Whiting Oil and Gas or other designated subsidiaries of the Company.  As of December 31, 2019, $48 million was available 
for additional letters of credit under the agreement. 

The  credit  agreement  provides  for  interest  only  payments  until  maturity,  when  the  credit  agreement  expires  and  all  outstanding 
borrowings are due.  Interest under the credit agreement accrues at the Company’s option at either (i) a base rate for a base rate loan 
plus a margin between 0.50% and 1.50% based on the ratio of outstanding borrowings to the borrowing base, where the base rate is 
defined as the greatest of the prime rate, the federal funds rate plus 0.5% per annum, or an adjusted LIBOR rate plus 1.0% per annum, 
or  (ii) an  adjusted  LIBOR  rate  for  a  Eurodollar  loan  plus  a  margin  between  1.50%  and  2.50%  based  on  the  ratio  of  outstanding 
borrowings  to  the  borrowing  base.    Additionally,  the  Company  incurs  commitment  fees  of  0.375%  or  0.50%  based  on  the  ratio  of 
outstanding  borrowings  to  the  borrowing  base  on  the  unused  portion  of  the aggregate commitments  of the lenders  under  the credit 
agreement, which are included as a component of interest expense.  At December 31, 2019, the weighted average interest rate on the 
outstanding principal balance under the credit agreement was 3.3%. 

The credit agreement matures on April 12, 2023, provided that if at any time and for so long as any senior notes (other than the 2020 
Convertible Senior Notes) have a maturity date prior to 91 days after April 12, 2023, the maturity date shall be the date that is 91 days 
prior to the maturity of such senior notes.  On September 13, 2019, the Company amended the credit agreement to, among other things, 
permit the repurchase, redemption, prepayment or other acquisition or retirement for value of any senior notes (as defined in the credit 
agreement) if: (i) such transaction is for a price not greater than an amount equal to par plus accrued and unpaid interest and fees and 
any applicable make-whole  premium,  (ii) immediately after  giving effect to  such transaction, there is  unused  availability  under the 
facility of not less than the greater of $100 million or 15% of the then effective total commitments, and  (iii) the Company’s ratio of 
consolidated total debt as of the date of such transaction (upon giving effect thereto) to EBITDAX (as defined in the credit agreement) 
during the last four quarters is not greater than 3.25 to 1.0.  The Company’s business plan includes the intent to refinance certain senior

notes, including the convertible senior notes due in 2020 and the senior notes due in 2021, as permitted by the September 13, 2019 
amendment to the credit agreement.  Consequently, the Company has classified the credit agreement as long-term debt. 

The  credit  agreement  contains  restrictive  covenants  that  may  limit  the  Company’s  ability  to,  among  other  things,  incur  additional 
indebtedness, sell assets, make loans to others, make investments, enter into mergers, enter into hedging contracts, incur liens and engage 
in certain other transactions without the prior consent of its lenders.  Except for limited exceptions, the credit agreement also restricts 
the Company’s  ability  to  make  any  dividend  payments or distributions  on  its  common  stock.   These  restrictions  apply  to  all  of  the 
Company’s restricted subsidiaries (as defined in the credit agreement).  As of December 31, 2019, there were no retained earnings free 
from restrictions.  The credit agreement requires the Company, as of the last day of any quarter, to maintain the following ratios (as 
defined in the credit agreement): (i) a consolidated current assets to consolidated current liabilities ratio (which includes an add back of 
the  available  borrowing  capacity  under  the  credit  agreement)  of  not  less  than  1.0  to  1.0  and  (ii) a  total  debt  to  last  four  quarters’ 
EBITDAX ratio of not greater than 4.0 to 1.0.  As of December 31, 2019, the Company was in compliance with its covenants under the 
credit agreement. 

Under Whiting Oil and Gas’ credit agreement, a cross default provision provides that a default under certain other debt of the Company 
or certain of its subsidiaries in an aggregate principal amount exceeding  $100 million may constitute an event of default under such 
credit agreement.  Additionally, under the indentures governing our senior notes and senior convertible notes, a cross-default provision 
provides that a default under certain other debt of the Company or certain of its subsidiaries in an aggregate principal amount exceeding 
$100 million (or $50 million in the case of the 2021 Senior Notes) may constitute an event of default under such indenture. 

The obligations of Whiting Oil and Gas under the credit agreement are collateralized by a first lien on substantially all of Whiting Oil 
and Gas’ and Whiting Resource Corporation’s properties.  The Company has guaranteed the obligations of Whiting Oil and Gas under 
the credit agreement and has pledged the stock of its subsidiaries as security for its guarantee. 

Senior Notes, Convertible Senior Notes and Senior Subordinated Notes 

Senior  Notes  and  Senior  Subordinated  Notes—In  September 2010,  the  Company  issued  at  par  $350  million  of  6.5%  Senior 
Subordinated Notes due October 2018 (the “2018 Senior Subordinated Notes”). 

In September 2013, the Company issued at par $1.1 billion of 5.0% Senior Notes due March 15, 2019 (the “2019 Senior Notes”) and 
$800 million of 5.75% Senior Notes due March 15, 2021, and issued at 101% of par an additional $400 million of 5.75% Senior Notes 
due March 15, 2021 (collectively, the “2021 Senior Notes”).  The debt premium recorded in connection with the issuance of the 2021 
Senior Notes is being amortized to interest expense over the term of the notes using the effective interest method,  with an effective 
interest rate of 5.5% per annum. 

In March 2015, the Company issued at par $750 million of 6.25% Senior Notes due April 1, 2023 (the “2023 Senior Notes”). 

In December 2017, the Company issued at par $1.0 billion of 6.625% Senior Notes due January 15, 2026 (the “2026 Senior Notes” and 
together with the 2021 Senior Notes and the 2023 Senior Notes, the “Senior Notes”).  The Company used the net proceeds from this 
offering to redeem in January 2018 all of the then outstanding 2019 Senior Notes.  Refer to “Redemption of 2019 Senior Notes” below 
for more information on the redemption of the 2019 Senior Notes. 

During  2016,  the  Company  exchanged  (i) $75  million  aggregate  principal  amount  of  its  2018  Senior  Subordinated  Notes,  (ii) $139 
million aggregate principal amount of its 2019 Senior Notes, (iii) $326 million aggregate principal amount of its 2021 Senior Notes, and 
(iv) $342 million aggregate principal amount of its 2023 Senior Notes, for the same aggregate principal amount of convertible notes.  
Subsequently during 2016, all $882 million aggregate principal amount of these convertible notes was converted into approximately 
21.6 million shares of the Company’s common stock pursuant to the terms of the notes. 

Redemption of 2018 Senior Subordinated Notes.  In February 2017, the Company paid $281 million to redeem all of the then outstanding 
$275 million aggregate principal amount of 2018 Senior Subordinated Notes, which payment consisted of the 100% redemption price 
plus all accrued and unpaid interest on the notes.  The Company financed the redemption with borrowings under its credit agreement.  
As a result of the redemption, Whiting recognized a $2 million loss on extinguishment of debt. 

Redemption of 2019 Senior Notes.  In January 2018, the Company paid $1.0 billion to redeem all of the remaining $961 million aggregate 
principal amount of the 2019 Senior Notes, which payment consisted of the  102.976% redemption price plus all accrued and unpaid 

82 

interest on the notes. The Company financed the redemption with proceeds from the issuance of the 2026 Senior Notes and borrowings 
under its credit agreement. As a result of the redemption, the Company recognized a $31 million loss on extinguishment of debt. 

Repurchases of 2021 Senior Notes.  In September 2019, the Company paid $24 million to repurchase $25 million aggregate principal 
amount of the 2021 Senior Notes, which payment consisted of the average 94.708% purchase price plus all accrued and unpaid interest 
on the notes.  The Company financed the repurchases with borrowings under its credit agreement.  As a result of the repurchases, the 
Company recognized a $1 million gain on extinguishment of debt, which included a non-cash charge for the acceleration of unamortized 
debt issuance costs and debt premium on the notes. 

In October 2019, the Company paid an additional $72 million to repurchase $75 million aggregate principal amount of the 2021 Senior 
Notes, which payment consisted of the average 95.467% purchase price plus all accrued and unpaid interest on the notes.  The Company 
financed the repurchases with borrowings under its credit agreement.  As a result of the repurchases, the Company recognized  a $3 
million gain on extinguishment of debt, which included a noncash charge for the acceleration of unamortized debt issuance costs and 
debt premium on the notes.  As of December 31, 2019, $774 million of 2021 Senior Notes remained outstanding.  

2020 Convertible Senior Notes—In March 2015, the Company issued at par $1,250 million of 1.25% Convertible Senior Notes due 
April 1,  2020  (the  “2020 Convertible  Senior  Notes”)  for  net  proceeds  of  $1.2  billion,  net of initial purchasers’  fees  of $25 million.  
During  2016,  the  Company  exchanged  $688  million aggregate  principal  amount  of its  2020  Convertible  Senior  Notes for the  same 
aggregate principal amount of new mandatory convertible senior notes.  Subsequently during 2016, all $688 million aggregate principal 
amount of these mandatory convertible notes was converted into approximately 17.8 million shares of the Company’s common stock 
pursuant to the terms of the notes. 

In September 2019, the Company paid $299 million to complete a cash tender offer for $300 million aggregate principal amount of the 
2020 Convertible Senior Notes, which payment consisted of the 99.0% purchase price plus all accrued and unpaid interest on the notes, 
which were allocated to the liability and equity components based on their relative fair values.  The Company financed the tender offer 
with borrowings under its credit agreement.  As a result of the tender offer, the Company recognized a $4 million gain on extinguishment 
of debt, which was net of a  $7 million charge for the non-cash write-off of unamortized debt issuance costs and debt discount and a 
$1 million charge for transaction costs.  In addition, the Company recorded an $8 million reduction to the equity component of the 2020 
Convertible Senior Notes.  There was no deferred tax impact associated with this reduction due to the full valuation allowance in effect 
as of September 30, 2019. 

The remaining $262 million aggregate principal amount of 2020 Convertible Senior Notes outstanding as of December 31, 2019 are 
convertible exclusively at the holder’s option.  Prior to January 1, 2020, the 2020 Convertible Senior Notes  were convertible only upon 
the achievement of certain contingent market conditions.  As of December 31, 2019, none of the contingent market conditions allowing 
holders of the 2020 Convertible Senior Notes to convert these notes had been met.  On or after January 1, 2020, the 2020 Convertible 
Senior Notes are convertible at any time until the second scheduled trading day immediately preceding the April 1, 2020 maturity date 
of the notes.  The notes are convertible at a current conversion rate of 6.4102 shares of Whiting’s common stock per $1,000 principal 
amount of the notes, which is equivalent to a current conversion price of approximately $156.00.  The conversion rate will be subject to 
adjustment  in  some events.    In  addition, following  certain corporate events that  occur  prior  to  the maturity date, the Company  will 
increase, in certain circumstances, the conversion rate for a holder who elects to convert its 2020 Convertible Senior Notes in connection 
with such corporate event.  The Company has the option to settle conversions of these notes with cash, shares of common stock or a 
combination of cash and common stock at its election.  The Company’s intent is to settle the principal amount of the 2020 Convertible 
Senior Notes in cash upon conversion.  At maturity, the Company must settle all outstanding 2020 Convertible Senior Notes in cash.  
The Company’s business plan includes the intent to settle the outstanding 2020 Convertible Senior Notes using borrowings under its 
credit agreement.  Accordingly, the outstanding balance has been classified as long-term debt in the consolidated balance sheet as of 
December 31, 2019. 

Upon issuance, the Company separately accounted for the liability and equity components of the 2020 Convertible Senior Notes.  The 
liability component was recorded at the estimated fair value of a similar debt instrument without the conversion feature.  The difference 
between the principal amount of the 2020 Convertible Senior Notes and the estimated fair value of the liability component was recorded 
as a debt discount and is being amortized to interest expense over the term of the notes using the effective interest method, with an 
effective interest rate of 5.6% per annum.  The fair value of the liability component of the 2020 Convertible Senior  Notes as of the 
issuance date was estimated at $1.0 billion, resulting in a debt discount at inception of $238 million.  The equity component, representing 
the value of the conversion option, was computed by deducting the fair value of the liability component from the initial proceeds of the 
2020 Convertible Senior Notes issuance.  This equity component was recorded, net of deferred taxes and issuance costs, in additional 

83 

paid-in  capital  within  shareholders’  equity,  and  will  not  be  remeasured  as  long  as  it  continues  to  meet  the  conditions  for  equity 
classification. 

Transaction costs related to the 2020 Convertible Senior Notes issuance were allocated to the liability and equity components based on 
their relative fair values.  Issuance costs attributable to the liability component were recorded as a reduction to the carrying value of 
long-term debt on the consolidated balance sheet and are being amortized to interest expense over the term of the notes using the effective 
interest  method.    Issuance costs attributable  to  the equity  component  were  recorded  as  a  charge  to  additional  paid-in capital  within 
shareholders’ equity. 

The 2020 Convertible Senior Notes consisted of the following at December 31, 2019 and 2018 (in thousands):

totaled $26 million, $29 million and $28 million for the years ended December 31, 2019, 2018 and 2017, respectively. 

Security and Guarantees 

The  Senior  Notes  and  the  2020  Convertible  Senior  Notes  are  unsecured  obligations  of  Whiting  Petroleum  Corporation  and  these 
unsecured obligations are subordinated to all of the Company’s secured indebtedness, which consists of Whiting Oil and Gas’ credit 
agreement. 

The  Company’s  obligations  under  the  Senior  Notes  and  the  2020  Convertible  Senior  Notes  are  guaranteed  by  the  Company’s 
100%-owned  subsidiaries,  Whiting  Oil  and  Gas,  Whiting  US  Holding  Company,  Whiting  Canadian  Holding  Company  ULC  and 
Whiting  Resources  Corporation  (the  “Guarantors”).    These  guarantees  are  full  and  unconditional  and  joint  and  several  among  the 
Guarantors.  Any subsidiaries other than these Guarantors are minor subsidiaries as defined by Rule 3-10(h)(6) of Regulation S-X of 
the SEC.  Whiting Petroleum Corporation has no assets or operations independent of this debt and its investments in its consolidated 
subsidiaries. 

6.        ASSET RETIREMENT OBLIGATIONS 

The  Company’s  asset  retirement  obligations  represent  the  present  value  of  estimated  future  costs  associated  with  the  plugging  and 
abandonment of oil and gas wells, removal of equipment and facilities from leased acreage, and land restoration (including removal of 
certain onshore and offshore facilities in California) in accordance with applicable local, state and federal laws and the terms of the 
Company’s lease  agreements.   The  current  portions as  of December 31,  2019 and  2018  were $4 million  and  have  been included in

The Company is exposed to certain risks relating to its ongoing business operations, and it uses derivative instruments to manage its 
commodity price risk.  In addition, the Company periodically enters into contracts that contain embedded features which are required to 
be bifurcated and accounted for separately as derivatives. 

Commodity Derivative Contracts—Historically, prices received for crude oil and natural gas production have been volatile because of 
supply and demand factors, worldwide political factors, general economic conditions and seasonal weather patterns.  Whiting primarily 
enters into derivative contracts such as crude oil collars, swaps and options, as well as sales and delivery contracts, to achieve a more 
predictable cash flow by reducing its exposure to commodity price volatility, thereby ensuring adequate funding for the Company’s 
capital programs and facilitating the management of returns on drilling programs and acquisitions.  The Company does not enter into 
derivative contracts for speculative or trading purposes. 

Crude  Oil  Collars,  Swaps  and  Options.    Collars  are  designed  to  establish  floor  and  ceiling  prices  on  anticipated  future  oil  or  gas 
production, while swaps and options establish a fixed price for anticipated future oil or gas production.  While the use of these derivative 
instruments limits the downside risk of adverse price movements, they may also limit future revenues from favorable price movements. 

The table below details the Company’s collar, swap and option derivatives entered into to hedge forecasted crude oil production revenues 
as of December 31, 2019.

Crude Oil Sales and Delivery Contract.  The Company had a long-term crude oil sales and delivery contract for oil volumes produced 
from its Redtail  field in  Colorado.   Whiting  determined that  this  contract  would  not qualify  for the  “normal  purchase normal  sale” 
exclusion and therefore reflected the contract at fair value in the consolidated financial statements prior to settlement.  On February 1, 
2018,  Whiting  paid  $61  million  to  the  counterparty  to  settle  all  future  minimum  volume  commitments  under  this  agreement.  
Accordingly,  this  crude  oil  sales  and  delivery  contract  was  fully  terminated  and  the  fair  value  of  the  corresponding  derivative  was 
therefore zero as of that date. 

Embedded Derivatives—In July 2016, the Company entered into a purchase and sale agreement with the buyer of its North Ward Estes 
Properties, whereby the buyer agreed to pay Whiting additional proceeds of  $100,000 for every $0.01 that, as of June 28, 2018, the 
average  NYMEX crude  oil  futures  contract price  for  each month  from  August 2018 through July 2021  is  above  $50.00/Bbl  up  to a 
maximum amount of $100 million.  The Company determined that this NYMEX-linked contingent payment was not clearly and closely 
related to the host contract, and the Company therefore bifurcated this embedded feature and reflected it at its estimated fair value in the 
consolidated financial statements.  On July 19, 2017, the buyer paid $35 million to Whiting to settle this NYMEX-linked contingent 
payment, and accordingly, the embedded derivative’s fair value was zero as of December 31, 2019 and 2018. 

Derivative Instrument Reporting—All derivative instruments are recorded in the consolidated financial statements at fair value, other 
than derivative instruments that meet the “normal purchase normal sale” exclusion or other derivative scope exceptions.  The following 
table summarizes the effects of derivative instruments on the consolidated statements of operations for the years ended December 31,

(1)  Because counterparties to the Company’s financial derivative contracts subject to master netting arrangements are lenders under 
Whiting Oil and Gas’ credit agreement, which eliminates its need to post or receive collateral associated with its derivative positions, 
columns for cash collateral pledged or received have not been presented in these tables. 

Contingent Features in Financial Derivative Instruments.  None of the Company’s derivative instruments contain credit-risk-related 
contingent features.  Counterparties to the Company’s financial derivative contracts are high credit-quality financial institutions that are 
lenders under Whiting’s credit agreement.  The Company uses only credit agreement participants to hedge with, since these institutions 
are secured equally with the holders of Whiting’s bank debt, which eliminates the potential need to post collateral when Whiting is in a 
derivative liability position.  As a result, the Company is not required to post letters of credit or corporate guarantees for its derivative 
counterparties in order to secure contract performance obligations. 

8.        FAIR VALUE MEASUREMENTS 

The  Company  follows  FASB  ASC  Topic  820 – Fair  Value  Measurement  and  Disclosure  which  establishes  a  three-level  valuation 
hierarchy for disclosure of fair value measurements.  The valuation hierarchy categorizes assets and liabilities measured at fair value 
into one of three different levels depending on the observability of the inputs employed in the measurement.  The three levels are defined 
as follows: 

• 

• 

• 

Level  1:  Quoted  Prices  in  Active  Markets  for  Identical  Assets –  inputs  to  the  valuation  methodology  are  quoted  prices 
(unadjusted) for identical assets or liabilities in active markets. 

Level 2:  Significant Other Observable Inputs – inputs to the valuation methodology include quoted prices for similar assets and 
liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially 
the full term of the financial instrument. 

Level 3:  Significant Unobservable Inputs – inputs to the valuation methodology are unobservable and significant to the fair value 
measurement. 

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the 
fair value measurement.  The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety 
requires judgment and considers factors specific to the asset or liability.   

Cash, cash equivalents, accounts receivable and accounts payable are carried at cost, which approximates their fair value because of the 
short-term maturity of these instruments.  The Company’s credit agreement has a recorded value that approximates its fair value since 
its variable interest rate is tied to current market rates and the applicable margins represent market rates.

The following methods and assumptions were used to estimate the fair values of the Company’s financial assets and liabilities that are 
measured on a recurring basis: 

Commodity Derivatives.  Commodity derivative instruments consist mainly of collars, swaps and options for crude oil.  The Company’s 
collars, swaps and options are valued based on an income approach.  Both the option and swap models consider various assumptions, 
such as quoted forward prices for commodities, time value and volatility factors.  These assumptions are observable in the marketplace 
throughout the full term of the contract, can be derived from observable data or are supported by observable levels at which transactions 
are executed in the marketplace, and are therefore designated as Level 2 within the valuation hierarchy.  The discount rates used in the 
fair values of these instruments include a measure of either the Company’s or the counterparty’s nonperformance risk, as appropriate.  
The Company utilizes its counterparties’ valuations to assess the reasonableness of its own valuations. 

In  addition,  the  Company  had  a  long-term  crude  oil  sales  and  delivery  contract,  whereby  it  had  committed  to  deliver  certain  fixed 
volumes  of  crude  oil  produced  from  its  Redtail  field  in  Colorado.    Whiting  determined  that  the  contract  did  not  meet  the  “normal 
purchase  normal  sale”  exclusion,  and  therefore  reflected  this  contract  at  fair  value  in  its  consolidated  financial  statements  prior  to 
settlement.    This  commodity  derivative  was  valued  based  on  a  probability-weighted  income  approach  which  considered  various 
assumptions,  including  quoted  spot  prices  for  commodities,  market  differentials  for  crude  oil,  U.S.  Treasury  rates  and  either  the

Company’s or the counterparty’s nonperformance risk, as appropriate.  The assumptions used in the valuation of the crude oil sales and 
delivery contract included certain market differential metrics that were unobservable during the term of the contract.  Such unobservable 
inputs were significant to the contract valuation methodology, and the contract’s fair value was therefore designated as Level 3 within 
the  valuation  hierarchy.    On  February 1,  2018,  Whiting  paid  $61  million  to  the  counterparty  to  settle  all  future  minimum  volume 
commitments under this agreement.  Accordingly, this derivative was settled in its entirety as of that date. 

Level 3 Fair Value Measurements—The Company did not have any amounts designated as Level 3 in the valuation hierarchy as of and

Non-recurring Fair  Value  Measurements—The  Company applies  the  provisions  of  the  fair  value  measurement  standard  on a  non-
recurring basis to its non-financial assets and liabilities, including proved property.  These assets and liabilities are not measured at fair 
value on an ongoing basis but are subject to fair value adjustments only in certain circumstances.  The Company did not recognize any 
impairment write-downs with respect to its proved property during the years ended December 31, 2019 and 2018.  The following table 
presents  information  about  the  Company’s  non-financial  assets  measured  at  fair  value  on  a  non-recurring  basis  for  the  year  ended

(1)  During the fourth quarter of 2017, proved oil and gas properties at the Redtail field in the Denver-Julesburg Basin (the “DJ Basin”) 
in Weld County, Colorado, with a previous carrying amount of $1.2 billion were written down to their fair value as of December 31, 
2017  of  $389  million,  resulting  in  a  non-cash  impairment  charge  of  $835  million  which  was  recorded  within  exploration  and 
impairment expense. 

The following methods and assumptions were used to estimate the fair values of the non-financial assets in the table above: 

Proved  Property  Impairments.    The  Company  tests  proved  property  for  impairment  whenever  events  or  changes  in  circumstances 
indicate that the fair value of these assets may be reduced below their carrying value.  Based on well performance results in the DJ 
Basin,  the  Company  reduced  its  reserves  at  its  Redtail  field  during  the  fourth  quarter  of  2017,  and  performed  a  proved  property 
impairment test as of December 31, 2017.  The fair value was ascribed using income approach analyses based on the net discounted 
future cash flows from the producing property and related assets.  The discounted cash flows were based on management’s expectations 
for the future.  Unobservable inputs included estimates of future oil and gas production from the Company’s reserve reports, commodity 
prices based on sales contract terms or forward price curves (adjusted for basis differentials), operating and development costs, and a 
discount rate based on the Company’s weighted-average cost of capital (all of which were designated as Level 3 inputs within the fair 
value hierarchy).  The impairment test indicated that a proved property impairment had occurred, and the Company therefore recorded 
a non-cash impairment charge to reduce the carrying value of the impaired property to its fair value at December 31, 2017.

Common Stock 

Reverse Stock Split.  On November 8, 2017 and following approval by the Company’s stockholders of an amendment to its certificate 
of incorporation to effect a reverse stock split, the Company’s Board of Directors approved a reverse stock split of Whiting’s common 
stock at a ratio of one-for-four and a reduction in the number of authorized shares of the Company’s common stock from 600,000,000 
shares to 225,000,000.  Whiting’s common stock began trading on a split-adjusted basis on November 9, 2017 upon opening of the New 
York Stock Exchange trading day.  All share and per share amounts in these consolidated financial statements and related notes for 
periods prior to November 2017 have been retroactively adjusted to reflect the reverse stock split. 

Noncontrolling  Interest—The  Company’s  noncontrolling  interest  represented  an  unrelated  third  party’s  25%  ownership  interest  in 
Sustainable Water Resources, LLC (“SWR”).  During the third quarter of 2017, the third party’s ownership interest in SWR was assigned 
back to SWR.  The table below summarizes the activity for the equity attributable to the noncontrolling interest (in thousands):

The Company recognizes revenue in accordance with FASB ASC Topic 606 – Revenue from Contracts with Customers (“ASC 606”).  
Revenue is recognized at the point in time at which the Company’s performance obligations under its commodity sales contracts are 
satisfied and control of the commodity is transferred to the customer.  The Company has determined that its contracts for the sale of 
crude  oil,  unprocessed  natural  gas,  residue  gas  and  NGLs  contain  monthly  performance  obligations  to  deliver  product  at  locations 
specified in the contract.  Control is transferred at the delivery location, at which point the performance obligation has been satisfied 
and  revenue  is  recognized.    Fees  included  in  the  contract  that  are  incurred  prior  to  control  transfer  are  classified  as  transportation, 
gathering, compression and  other, and  fees  incurred  after control transfers  are  included as  a  reduction  to  the  transaction  price.  The 
transaction price at which revenue is recognized consists entirely of variable consideration based on quoted market prices less various 
fees and the quantity of volumes delivered.  The table below presents the disaggregation of revenue by product type for the years ended 
December 31, 2019 and 2018 (in thousands):

Whiting receives payment for product sales from one to three months after delivery.  At the end of each month when the performance 
obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from customers are accrued in accounts 
receivable trade, net in the consolidated balance sheets.  As of December 31, 2019 and 2018, such receivable balances were $161 million 
and $165 million, respectively.  Variances between the Company’s estimated revenue and actual payments are recorded in the month 
the  payment  is  received,  however,  differences  have  been  and  are  insignificant.   Accordingly,  the  variable  consideration  is  not 
constrained. 

The Company has elected to utilize the practical expedient in ASC 606 that states the Company is not required to disclose the transaction 
price  allocated  to  remaining  performance  obligations  if  the  variable  consideration  is  allocated  entirely  to  a  wholly  unsatisfied 
performance  obligation.   Under  the  Company’s  contracts,  each  monthly  delivery  of  product  represents  a  separate  performance 
obligation, therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance 
obligations is not required.

11.        STOCK-BASED COMPENSATION 

Equity  Incentive  Plan—The  Company  maintains  the  Whiting  Petroleum  Corporation  2013  Equity  Incentive  Plan,  as  amended  and 
restated (the “2013 Equity Plan”), which replaced the Whiting Petroleum Corporation 2003 Equity Incentive Plan (the “2003 Equity 
Plan”)  and  originally granted  the authority to  issue  1,325,000  shares  of the  Company’s common  stock.    During  2016,  shareholders 
approved  an  amendment  to  the  2013  Equity  Plan  granting  the  authority  to  issue  an  additional  1,375,000  shares  of  the  Company’s 
common stock.  In May 2019, shareholders approved an additional amendment to the 2013 Equity Plan granting the authority to issue 
an additional 3,000,000 shares of the Company’s common stock.  Upon shareholder approval of the 2013 Equity Plan, the 2003 Equity 
Plan was terminated.  The 2003 Equity Plan continues to govern awards that were outstanding as of the date of its termination, which 
awards remain in effect pursuant to their terms.  Any shares netted or forfeited under the 2003 Equity Plan and any shares forfeited 
under the 2013 Equity Plan will be available for future issuance under the 2013 Equity Plan.  However, shares netted for tax withholding 
under the 2013 Equity Plan will be cancelled and will not be available for future issuance.  Under the amended and restated 2013 Equity 
Plan, during any calendar year, no officer or other key employee participant may be granted options or stock appreciation rights for 
more than 500,000 shares of common stock or more than 500,000 shares of restricted stock (“RSAs”), restricted stock units (“RSUs”), 
performance shares (“PSAs”) or performance share units (“PSUs”), the value of which is based on the fair market value of a share of 
common stock.  In addition, no non-employee director participant may be granted during any calendar year options or stock appreciation 
rights for more than 25,000 shares of common stock, or more than 25,000 shares of RSAs or RSUs.  As of December 31, 2019, 3,698,933 
shares of common stock remained available for grant under the 2013 Equity Plan. 

The Company grants service-based RSAs and RSUs to executive officers and employees, which generally vest ratably over a three-year 
service period.  The Company also grants service-based RSAs to directors, which generally vest over a  one-year service period.  In 
addition, the Company grants PSAs and PSUs to executive officers that are subject to market-based vesting criteria, which generally 
vest  over  a  three-year  service  period.    The  Company  accounts  for  forfeitures  of  awards  granted  under  these  plans  as  they  occur  in 
determining  compensation  expense.    The  Company  recognizes  compensation  expense  for  awards  subject  to  market-based  vesting 
conditions regardless of whether it becomes probable that these conditions will be achieved or not, and compensation expense for share-
settled awards is not reversed if vesting does not actually occur. 

During 2019, 2018 and 2017, 467,055, 249,983 and 538,194 shares, respectively, of service-based RSAs and RSUs were granted to 
employees, executive officers and directors under the 2013 Equity Plan.  The Company determines compensation expense for these 
share-settled awards using their fair value at the grant date, which is based on the closing bid price of the Company’s common stock on 
such date.  The weighted average grant date fair value of service-based RSAs and RSUs was $24.65 per share, $32.34 per share and 
$40.66 per share for the years ended December 31, 2019, 2018, and 2017, respectively. 

During 2019 and 2018, 774,665 and 308,432 shares, respectively, of service-based RSUs were granted to employees under the 2013 
Equity  Plan.  These  awards  will  be  settled  in cash  and are  recorded  as  a  liability  in  the consolidated balance  sheets.   The  Company 
determines compensation expense for cash-settled RSUs using the fair value at the end of each reporting period, which is based on the 
closing bid price of the Company’s common stock on such date.  

During 2019 and 2018, 347,493 and 230,932 shares, respectively, of PSAs and PSUs subject to certain market-based vesting criteria 
were granted to executive officers under the 2013 Equity Plan.  The market-based awards cliff vest on the third anniversary of the grant 
date, and the number of shares that will vest at the end of that three-year performance period is determined based on the rank of Whiting’s 
cumulative stockholder return compared to the stockholder return of a peer group of companies on each anniversary of the grant date 
over the three-year performance period.  The number of awards earned could range from zero up to two times the number of shares 
initially granted.  However, awards earned up to the target shares granted (or  100%) will be settled in shares, while awards earned in 
excess of the target shares granted will be settled in cash.  The cash-settled component of such awards is recorded as a liability in the 
consolidated  balance  sheets and  will  be  remeasured  at  fair value using  a  Monte  Carlo  valuation model  at  the end  of  each  reporting 
period.   

During 2017, 168,466 PSAs subject to certain market-based vesting criteria were granted to executive officers under the 2013 Equity 
Plan.  These market-based awards cliff vest on the third anniversary of the grant date, and the number of shares that will vest at the end 
of  that  three-year  performance  period is  determined  based on  the  rank  of Whiting’s cumulative  stockholder  return  compared  to  the 
stockholder return of a peer group of companies over the same three-year period.  The number of shares earned could range from zero 
up to two times the number of shares initially granted and will be settled entirely in shares. 

91 

For awards subject to market conditions, the grant date fair value is estimated using a Monte Carlo valuation model.  The Monte Carlo 
model is based on random projections of stock price paths and must be repeated numerous times to achieve a probabilistic assessment.  
Expected volatility is calculated based on the historical volatility and implied volatility of Whiting’s common stock, and the risk-free 
interest  rate  is  based  on  U.S.  Treasury  yield  curve  rates  with  maturities  consistent  with  the  three-year  vesting  period.    The  key 
assumptions used in valuing these market-based awards were as follows:

The weighted average grant date fair value of the market-based awards that will be settled in shares as determined by the Monte Carlo 
valuation model was $25.97 per share, $27.28 per share and $63.04 per share in 2019, 2018 and 2017, respectively.

As of December 31, 2019, there was $13 million of total unrecognized compensation cost related to unvested awards granted under the 
stock  incentive  plans.    That  cost  is  expected  to  be  recognized  over  a  weighted  average  period  of  2.0  years.  For  the  years  ended 
December 31,  2019,  2018  and  2017,  the  total  fair  value  of  the  Company’s  service-based  and  market-based  awards  vested  was  $12 
million, $16 million and $15 million, respectively. 

Stock Options—Stock options may be granted to certain executive officers of the Company with exercise prices equal to the closing 
market price of the Company’s common stock on the grant date.  There were no stock options granted under the 2013 Equity Plan during 
2019, 2018 or 2017.  The Company’s stock options vest ratably over a three-year service period from the grant date and are exercisable 
immediately upon vesting through the tenth anniversary of the grant date.

The Company’s July 1, 2016 note exchange transactions triggered an ownership shift within the meaning of Section 382 of the Internal 
Revenue  Code  (“IRC”)  due  to  the  “deemed  share  issuance”  that  resulted  from  the  note  exchanges.    The  ownership  shift  will  limit 
Whiting’s usage of certain of its net operating losses (“NOLs”) and tax credits in the future.  Accordingly, the Company recognized 
valuation allowances on its deferred tax assets totaling  $259 million.  In the third quarter of 2017 there was a partial release of this 
valuation allowance in the amount of $41 million associated with built-on gains on the sale of the FBIR Assets. 

As of December 31, 2019, the Company had federal NOL carryforwards of $3.4 billion, which is net of the IRC Section 382 limitation.  
The  Company  also  has  various  state  NOL  carryforwards.    The  determination  of  the  state  NOL  carryforwards  is  dependent  upon 
apportionment  percentages  and  state  laws  that  can  change  from  year  to  year  and  that  can  thereby  impact  the  amount  of  such 
carryforwards.    If unutilized,  the  majority  of  the  federal  NOLs  will  expire  between  2023  and  2037 and the  state  NOLs  will  expire 
between 2020 and 2037.  Any federal NOLs generated in 2018 or subsequent do not expire.  

EOR credits are a credit  against federal income taxes for certain costs related to extracting high-cost oil, utilizing certain prescribed 
enhanced tertiary recovery methods.  As of December 31, 2019, the Company had recognized aggregate EOR credits of $8 million.  As 
a result of the IRC Section 382 limitation in July 2016, the Company recorded a full valuation allowance on these credits. 

On  December 22,  2017,  Congress  passed the Tax  Cuts  and  Jobs  Act  (the “TCJA”).    The legislation  significantly  changed  the  U.S. 
corporate tax law by, among other things, lowering the U.S. corporate income tax rate from 35% to 21% beginning in January 2018, 
implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries.  FASB 
ASC Topic 740 – Income Taxes requires companies to recognize the impact of the changes in tax law in the period of enactment.  The 
SEC subsequently issued Staff Accounting Bulletin No. 118, which allowed registrants to record provisional amounts during a one-year 
“measurement period” similar to that used to account for business combinations.  The Company did not recognize any measurement 
period adjustments during 2018 and its accounting for the TCJA was complete as of December 31, 2018. 

Amounts recorded during the year ended December 31, 2017 related to the TCJA principally relate to the reduction in the U.S. corporate 
income tax rate to 21%, which resulted in (i) income tax expense of $51 million from the revaluation of the Company’s deferred tax 
assets and liabilities as of the date of enactment and (ii) an income tax benefit totaling $93 million related to a reduction in the Company’s 
existing valuation allowances.

Other elements of the TCJA that did not have an impact on the Company’s financial statements upon enactment of the TCJA, but may 
impact the Company’s income taxes in future periods include: (i) IRC Section 168(k) first-year optional bonus depreciation, (ii) repeal 
of the corporate alternative minimum tax, (iii) limitation on the usage of NOLs generated after 2017 to  80% of taxable income, (iv) 
additional  limitations  on  certain  meals  and  entertainment  expenses,  (v)  repeal  of  the  deduction  for  income  attributable  to  domestic 
production activities, (vi) like-kind exchange limitations for property other than real property, (vii) ability to capitalize and amortize 
intangible drilling costs under IRC Section 59(e), and (viii) interest deduction limitations under IRC Section 163(j).   

In assessing the realizability of deferred tax assets (“DTAs”), management considers whether it is more likely than not that some portion, 
or all, of the Company’s DTAs will not be realized.  In making such determination, the Company considers all available positive and 
negative evidence, including future reversals of temporary differences, tax-planning strategies and projected future taxable income and 
results of operations.  If the Company concludes that it is more likely than not that some portion, or all, of its DTAs will not be realized, 
the tax asset is reduced by a valuation allowance.  At December 31, 2019, the Company had a valuation allowance totaling $188 million, 
comprised of $138 million of NOL carryforward limitations under Section 382 of the IRC, $8 million of EOR credits, which will expire 
between 2023 and 2025, $1 million of short-term capital loss carryforwards that are not expected to be realized and a $41 million general 
valuation allowance against the Company’s net U.S. deferred tax assets. 

During the fourth quarter of 2019, the Company determined it no longer had the ability to indefinitely prevent the reversal of the outside 
basis difference related to Whiting Canadian Holding Company ULC, Whiting’s wholly owned subsidiary, which owns a  portion of 
Whiting’s U.S. assets obtained through the acquisition of Kodiak Oil and Gas Corporation during 2014.  Accordingly, the Company 
revised  its  assessment  related  to  noncurrent  Canadian  deferred  taxes  pursuant  to  ASC  740-30-25-17  and  recognized  a  $74  million 
deferred tax  liability as  well as  the  same  amount  of  deferred  income  tax expense as  of and for the year  ended  December  31,  2019 
associated with the outside basis difference related to Whiting Canadian Holding Company ULC. 

During 2018, the Company recorded an adjustment to its valuation allowance on DTAs totaling $30 million.  At December 31, 2018, 
the  Company  had  a  valuation  allowance  totaling  $152  million,  comprised  of  $138  million  of  NOL  carryforward  limitations  under 
Section 382  of  the  IRC,  $8  million  of  EOR  credits,  which  will  expire  between  2023  and  2025,  $5  million  of  Canadian  NOL 
carryforwards, which will expire between 2034 and 2035, and $1 million of short-term capital loss carryforwards that are not expected 
to be realized. 

As of December 31, 2019 and 2018, the Company did not have any uncertain tax positions.  For the years ended December 31, 2019, 
2018 and 2017, the Company did not recognize any interest or penalties with respect to unrecognized tax benefits, nor did the Company 
have  any  such  interest  or  penalties  previously  accrued.    The  Company  believes  that  it  is  reasonably  possible  that  no  increases  to 
unrecognized tax benefits will occur in the next twelve months. 

The Company files income tax returns in the U.S. federal jurisdiction and in various states, each with varying statutes of limitations.  
The 2015 through 2019 tax years generally remain subject to examination by federal and state tax authorities.  Additionally, the Company 
has Canadian income tax filings which remain subject to examination by the related tax authorities for the 2014 through 2019 tax years.

For the year  ended  December 31,  2019 the  Company  had  a  net loss  and therefore the diluted  earnings  per  share  calculation  for that 
period excludes the anti-dilutive effect of 344,671 shares of service-based awards and 3,511 shares of market-based awards.  In addition, 
the diluted earnings per share calculation for the year ended December 31, 2019 excludes the effect of 45,588 common shares for stock 
options that were out of the money as of December 31, 2019. 

For the year ended December 31, 2018, the diluted earnings per share calculation excludes the effect of 100,708 common shares for 
stock options that were out of the money as of December 31, 2018. 

For the year ended December 31, 2017, the Company had a net loss and therefore the diluted earnings per share  calculation for that 
period excludes the anti-dilutive effect of 509,744 shares of service-based awards, 22,946 shares of market-based awards and 1,083 
stock  options.    In  addition,  the  diluted  earnings  per  share  calculation  for  the year  ended  December 31,  2017  excludes  the  effect  of 
123,775 common shares for stock options that were out-of-the-money and 345,071 shares of market-based awards that did not meet the 
market-based vesting criteria as of December 31, 2017. 

Refer  to  the  “Stock-Based  Compensation”  footnote  for  further  information  on  the  Company’s  service-based  awards,  market-based 
awards and stock options. 

As discussed in the “Long-Term Debt” footnote, the Company has the option to settle conversions of the 2020 Convertible Senior Notes 
with cash, shares of common stock or any combination thereof.  Based on the current conversion price, the entire outstanding principal 
amount of the 2020 Convertible Senior Notes as of December 31, 2019 would be convertible into approximately 1.7 million shares of 
the Company’s common stock.  However, the Company’s intent is to settle the principal amount of the notes in cash upon conversion.  
As  a  result,  only  the  amount  by  which  the  conversion  value  exceeds  the  aggregate  principal  amount  of  the  notes  (the  “conversion 
spread”) is considered in the diluted earnings per share computation under the treasury stock method.  As of December 31, 2019, 2018 
and 2017, the conversion value did not exceed the principal amount of the notes.  Accordingly, there was no impact to diluted earnings 
per share or the related disclosures for those periods.

Pipeline Transportation Agreements—The Company has two effective agreements through 2024 with various third parties to facilitate 
the  delivery  of  its  produced  oil, gas and  NGLs to  market.   Under one  of  these  contracts, the  Company  has  committed to  pay  fixed 
monthly reservation fees on dedicated pipelines for natural gas and NGL transportation capacity, plus additional variable charges based 
on actual transportation volumes.  These fixed monthly reservation fees totaling approximately  $9 million have been included in the 
table above. 

The remaining contract contains a commitment to transport a minimum volume of crude oil or else pay for any deficiencies at a price 
stipulated in the contract.  Although minimum annual quantities are specified in the agreement, the actual oil volumes transported and 
their corresponding unit prices are variable over the term of the contract.  As a result, the future minimum payments for each of the five 
succeeding fiscal years are not fixed and determinable and are not therefore included in the table above.  As of December 31, 2019, the 
Company estimated the minimum future commitments under this transportation agreement to approximate $9 million through 2022. 

During 2019, 2018 and 2017, the cost of transportation of crude oil, natural gas and NGLs under these contracts amounted to $2 million, 
$2 million and $2 million, respectively. 

Purchase Contracts—The Company’s purchase obligation consists of a take-or-pay arrangement to buy volumes of water for use in the 
fracture stimulation process.  Under the terms of the agreement, the Company is obligated to purchase a minimum volume of water or 
else pay for any deficiencies at the price stipulated in the contract.  Although minimum daily quantities are specified in the agreement, 
the actual water volumes purchased and their corresponding unit prices are variable over the term of the contract.  As a result, the future 
minimum payments for each of the five succeeding fiscal years are not fixed and determinable and are not therefore included in the table 
above.    As  of  December 31,  2019,  the  Company  estimated  the  minimum  future  commitments  under  this  purchase  agreement  to 
approximate $8 million through 2020. 

As  a  result of the  Company’s  reduced  development operations  in  its  Redtail  field, Whiting  has made and  expects  to make periodic 
deficiency payments  under  this  purchase  contract during  the remaining  term,  which  expires  in  2020.   During  2019, 2018 and  2017, 
purchases of water under the Company’s take-or-pay arrangement amounted to $8 million, $8 million and $22 million, respectively, 
which included $8 million and $2 million of deficiency payments for the years ended December 31, 2019 and 2018, respectively, and 
insignificant deficiency payments for the year ended December 31, 2017.  

Water  Disposal  Agreement—The  Company  has a  water disposal agreement expiring  in  2024  under  which it  has contracted  for  the 
transportation and disposal of the produced water from its Redtail field.  Under the terms of the agreement, the Company is obligated to 
provide a minimum volume of produced water or else pay for any deficiencies at the price stipulated in the contract.  Although minimum 
monthly quantities are specified in the agreement, the actual water volumes disposed of and their corresponding unit prices are variable 
over the term of the contract.  As a result, the future minimum payments for each of the five succeeding fiscal years are not fixed and 
determinable and are therefore not included in the table above.  As of December 31, 2019, the Company estimated the minimum future 
commitments  under  this  disposal  agreement  to  approximate  $83  million  through  2024.    As  a  result  of  the  Company’s  reduced 
development operations at its Redtail field, Whiting has made and expects to make periodic deficiency payments under this contract.  
During 2019, 2018 and 2017, transportation and disposal of produced water amounted to $20 million, $19 million and $16 million, 
respectively, which includes $14 million, $5 million and $4 million of deficiency payments, respectively.   

97 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Delivery Commitments—The Company has three physical delivery contracts which require the Company to deliver fixed volumes of 
crude oil.  One of these delivery commitments became effective on June 1, 2017 upon completion of the Dakota Access Pipeline, and it 
is  tied to  crude  oil  production  from Whiting’s  Sanish  field in  Mountrail  County,  North  Dakota.   Under  the terms  of  the agreement, 
Whiting has committed to deliver 15 MBbl/d for a term of seven years.  The Company believes its production and reserves at the Sanish 
field are sufficient to fulfill this delivery commitment, and therefore expects to avoid any payments for deficiencies under this contract. 

The second delivery contract is tied to oil production in the Williston Basin.  The effective date of this contract is contingent upon the 
completion of certain related pipelines, which are currently expected to be brought online in 2021.  Under the terms of the agreement, 
Whiting  has committed to  deliver  10  MBbl/d  for a term  of  seven  years.   The  Company  believes  its  production and  reserves in  the 
Williston Basin are sufficient to fulfill this delivery commitment, and therefore expects to avoid any payments for deficiencies under 
this contract. 

The third delivery contract is tied to crude oil production at Whiting’s Redtail field in Weld County, Colorado.  As of December 31, 
2019, this contract contains remaining delivery commitments of 4.1 MMBbl of crude oil through the end of the contract’s term in April 
2020.  The Company has determined that it is not probable that future oil production from its Redtail field will be sufficient to meet the 
minimum volume requirements specified in these physical delivery contracts, and as a result, the Company expects to make periodic 
deficiency payments for any shortfalls in delivering the minimum committed volumes. 

During 2019, 2018 and 2017, total deficiency payments under these contracts, as well as a previous Redtail contract that was terminated 
in February 2018, amounted to $64 million, $39 million and $66 million, respectively.  The Company recognizes any monthly deficiency 
payments in the period in which the underdelivery takes place and the related liability has been incurred.  The table above does not 
include any such deficiency payments that may be incurred under the Company’s physical delivery contracts, since it cannot be predicted 
with accuracy the amount and timing of any such penalties incurred. 

Litigation—The Company is subject to litigation, claims and governmental and regulatory proceedings arising in the ordinary course 
of business.  The Company accrues a loss contingency for these lawsuits and claims when it is probable that a loss has been incurred 
and  the amount  of the  loss  can  be  reasonably estimated.  While  the  outcome  of  these lawsuits and  claims  cannot  be predicted  with 
certainty, it is the opinion of the Company’s management that the loss for any litigation matters and claims that are reasonably possible 
to occur will not have a material adverse effect, individually or in the aggregate, on its consolidated financial position, cash flows or 
results of operations.  The Company is involved in litigation related to a payment arrangement with a third party which currently claims 
damages up to $41 million, as well as court costs and interest, that is scheduled to go to trial in May 2020.  Certain amounts have been 
accrued  in  accrued  liabilities  and  other  in  the  consolidated  balance  sheet  as  of  December 31,  2019  and  general  and  administrative 
expenses in the consolidated statement of operations for the year ended December 31, 2019 based on the determination that it is probable 
that a loss has been incurred and can be reasonably estimated. 

15.       CAPITALIZED EXPLORATORY WELL COSTS

16.       RESTRUCTURING 

On July 31, 2019, the Company executed a workforce reduction as part of an organizational redesign and cost reduction strategy to 
better align its  business  with the  current  operating  environment  and  drive  long-term  value.   In  connection  with  these activities, the 
Company incurred $8 million in net restructuring costs associated with one-time employee termination benefits.  These restructuring 
costs are included in general and administrative expenses in the consolidated statements of operations. 

17.       SUBSEQUENT EVENTS 

On January 9, 2020, the Company completed the divestiture of its interests in 30 non-operated, producing oil and gas wells and related 
undeveloped  acreage  located  in  McKenzie  County,  North  Dakota  for  aggregate  sales  proceeds  of  $25  million  (before  closing 
adjustments).

wells. 

Oil and Gas Reserve Quantities 

For all years presented, the Company’s independent petroleum engineers independently estimated all of the proved reserve quantities 
included in this Annual Report on Form 10-K.  In connection with the external petroleum engineers performing their independent reserve 
estimations, Whiting furnishes them with the following information for their review: (i) technical support data, (ii) technical analysis of 
geologic and engineering support information, (iii) economic and production data, and  (iv) the Company’s well ownership interests.  
The  independent  petroleum  engineers,  Cawley,  Gillespie &  Associates, Inc.,  evaluated  100%  of  the  Company’s  estimated  proved 
reserve quantities and their related pre-tax future net cash flows as of December 31, 2019.  Proved reserve estimates included herein 
conform to the definitions prescribed by the SEC.  Estimates of proved reserves are inherently imprecise and are continually subject to 
revision based on production history, results of additional exploration and development, price changes and other factors.

Notable changes in proved reserves for the year ended December 31, 2019 included the following: 

•  Extensions and discoveries.  In 2019, total extensions and discoveries of 34.0 MMBOE were primarily attributable to successful 
drilling in the Williston Basin.  Both the new wells drilled in this area as well as the PUD locations added as a result of drilling 
increased the Company’s proved reserves. 

• 

Sales  of  minerals in place.    Sales  of minerals  in  place  totaled  4.9  MMBOE  during  2019 and  were primarily  attributable to the 
disposition of certain non-operated properties in North Dakota as further described in the “Acquisitions and Divestitures” footnote 
in the notes to the consolidated financial statements. 

•  Revisions to previous estimates.  In 2019, revisions to previous estimates decreased proved developed and undeveloped reserves by 
a net amount of 17.9 MMBOE.  Included in this change were upward revisions of 48.0 MMBOE to proved undeveloped reserves 
primarily located  in  the Williston  Basin in  locations  where  we  have  significant development activity  and past drilling  success.  
Offsetting these upward revisions were: (i) 32.9 MMBOE of downward adjustments caused by lower crude oil, NGL and natural 
gas prices incorporated into our reserve estimates at December 31, 2019 as compared to December 31, 2018, (ii) 19.3 MMBOE of 
downward adjustments primarily attributable to reservoir analysis and well performance across our Northern and Central Rockies

assets and (iii) 13.7 MMBOE of proved undeveloped reserves no longer expected to be developed within five years from their initial 
recognition.   

Notable changes in proved reserves for the year ended December 31, 2018 included the following: 

• 

• 

• 

Extensions and discoveries.  In 2018, total extensions and discoveries of 34.2 MMBOE were primarily attributable to successful 
drilling in the Williston Basin.  Both the new wells drilled in this area as well as the PUD locations added as a result of drilling 
increased the Company’s proved reserves. 

Purchases of minerals in place.  In 2018, total purchases of minerals in place of 25.7 MMBOE were primarily attributable to the 
acquisition  of  117  producing  oil  and  gas  wells  and  undeveloped  acreage  in  the  Williston  Basin,  further  described  in  the 
“Acquisitions and Divestitures” footnote in the notes to the consolidated financial statements, which increased the Company’s 
proved reserves. 

Revisions to previous estimates.  In 2018, revisions to previous estimates decreased proved developed and undeveloped reserves 
by a net amount of 110.7 MMBOE.  Included in these revisions were 99.9 MMBOE of proved undeveloped reserves no longer 
expected to be developed within five years from their initial recognition.  As a result of sustained lower crude oil prices in recent 
years, the Company has moved toward a more disciplined capital development program focused on the highest-return projects and 
the generation of free cash flow.  This shift in strategy resulted in a change in the timing of the Company’s development plans 
related to PUD reserves in certain areas.  These revisions do not represent the elimination of recoverable hydrocarbons physically 
in  place,  however,  as  they  may  be  developed  in  the  future.    In  addition,  there  were  38.1  MMBOE  of  downward  adjustments 
primarily attributable to reservoir analysis and well performance across the Company’s Northern and Central Rockies assets and 
27.3 MMBOE of upward adjustments caused by higher crude oil, NGL and natural gas prices incorporated into the Company’s 
reserve estimates at December 31, 2018 as compared to December 31, 2017. 

Notable changes in proved reserves for the year ended December 31, 2017 included the following: 

• 

• 

• 

Extensions and discoveries.  In 2017, total extensions and discoveries of 58.3 MMBOE were primarily attributable to successful 
drilling in the Williston Basin.  Both the new wells drilled in this area as well as the PUD locations added as a result of drilling 
increased the Company’s proved reserves. 

Sales of minerals in place.  Sales of minerals in place totaled 50.4 MMBOE during 2017 and were primarily attributable to the 
disposition of the FBIR Assets as further described in the “Acquisitions and Divestitures” footnote in the notes to the consolidated 
financial statements. 

Revisions to previous estimates.  In 2017, revisions to previous estimates increased proved developed and undeveloped reserves 
by a net amount of 37.1 MMBOE.  Included in these revisions were (i) 88.7 MMBOE of upward adjustments caused by higher 
crude oil, NGL and natural gas prices incorporated into the Company’s reserve estimates at December 31, 2017 as compared to 
December 31,  2016  and  (ii) 51.6  MMBOE  of  downward  adjustments  primarily  attributable  to  reservoir  analysis  and  well 
performance in the Redtail field. 

Standardized Measure of Discounted Future Net Cash Flows 

The Standardized Measure relating to proved oil and gas reserves and changes in the Standardized Measure relating to proved oil and 
natural gas reserves were prepared in accordance with the provisions of FASB ASC Topic 932,  Extractive Activities—Oil and Gas.  
Future cash inflows as of December 31, 2019, 2018 and 2017 were computed by applying average fiscal-year prices (calculated as the 
unweighted  arithmetic  average  of  the  first-day-of-the-month  price  for  each month  within  the  12-month  period  ended  December 31, 
2019, 2018 and 2017, respectively) to estimated future production.  Future production and development costs are computed by estimating 
the expenditures to be incurred in developing and producing the proved oil and natural gas reserves at year end, based on year-end costs 
and assuming the continuation of existing economic conditions. 

Future income tax expenses are calculated by applying appropriate year-end tax rates to future pretax net cash flows relating to proved 
oil and natural gas reserves, less the tax basis of properties involved.  Future income tax expenses give effect to permanent differences, 
tax credits and loss carryforwards relating to the proved oil and natural gas reserves.  Future net cash flows are discounted at a rate of 

102 

10% annually to derive the Standardized Measure.  This calculation does not necessarily result in an estimate of the fair value of the 
Company’s oil and gas properties. 

The Standardized Measure relating to proved oil and natural gas reserves is as follows (in thousands): 

Future cash flows  
Future production costs  
Future development costs  
Future income tax expense 
Future net cash flows  
10% annual discount for estimated timing of cash flows

Item 9A.      Controls and Procedures 

Evaluation of disclosure controls and procedures.  In accordance with Rule 13a-15(b) of the Securities Exchange Act of 1934 (the 
“Exchange Act”), our management evaluated, with the participation of our  Chairman, President and Chief Executive Officer and our 
Chief  Financial  Officer,  the  effectiveness  of  the  design  and  operation  of  our  disclosure  controls  and  procedures  (as  defined  in 
Rule 13a-15(e) under the Exchange  Act)  as  of  the  end of the  year ended  December 31,  2019.   Based  upon their  evaluation  of  these 
disclosure controls and procedures, the Chairman, President and Chief Executive Officer and the Chief Financial Officer concluded that 
the disclosure controls and procedures were effective as of December 31, 2019 to ensure that information required to be disclosed by us 
in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time  periods 
specified in the rules and forms of the Securities and Exchange Commission, and to ensure that information required to be disclosed by 
us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal 
executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. 

Management’s Annual Report on Internal Control over Financial Reporting.  The management of Whiting Petroleum Corporation 
and subsidiaries is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined 
in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934.  Our 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. 

Because of the inherent limitations of internal control over financial reporting, misstatements 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 the controls may become inadequate because of changes in conditions, or that the degree of compliance with 
the policies or procedures may deteriorate. 

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019 using the criteria 
set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission.  Based on this assessment, our management believes that, as of  December 31, 2019, our internal control over financial 
reporting was effective based on those criteria. 

The effectiveness of our internal control over financial reporting as of December 31, 2019 has been audited by Deloitte & Touche LLP, 
an independent registered public accounting firm, as stated in their report which is included herein on the following page. 

Changes in internal control over financial reporting.  There was no change in our internal control over financial reporting that occurred 
during the quarter ended December 31, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control 
over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of 
Whiting Petroleum Corporation 
Denver, Colorado 

Opinion on Internal Control over Financial Reporting 

We have audited the internal control over financial reporting of Whiting Petroleum Corporation and subsidiaries (the “Company”) as of 
December 31,  2019,  based  on  criteria  established  in  Internal  Control —  Integrated  Framework  (2013)  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (“COSO”).  In our opinion, the Company maintained, in all material respects, 
effective  internal  control  over  financial  reporting  as  of  December 31,  2019,  based  on  criteria  established  in  Internal  Control — 
Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), 
the consolidated financial statements as of and for the year ended December 31, 2019 of the Company and our report dated February 27, 
2020 expressed an unqualified opinion on those financial statements. 

Basis for Opinion 

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 Annual 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 are a public accounting firm registered with the PCAOB and are required to be independent with respect to the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB.  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. 

Definition and Limitations of Internal Control over Financial Reporting 

A company’s internal control over financial reporting is a process 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.    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 its inherent limitations, internal control 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 changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.
