·                  Williston Basin Oil-focused $200 Million CAPEX Budget

·                  4-Rig Drilling Program With 3 Operated Rigs

DENVER — December 6, 2010 /PRNewswire-FirstCall/ — Kodiak Oil & Gas Corp. (NYSE Amex: KOG), an oil and gas exploration and production company with assets in the Williston Basin of North Dakota and Montana and in the Green River Basin in southwestern Wyoming, today announced its preliminary 2011 capital expenditure budget (Capex) of $200 million.  The 2011 budget compares to Kodiak’s 2010 Capex budget of $75 million.

$200 Million 2011 Preliminary Capex Budget

Kodiak’s Board of Directors has approved a $200 million preliminary 2011 Capex budget allocated to oil and gas activities in the Bakken and Three Forks oil play in the Williston Basin of North Dakota.  The Company has allocated $150 million to the drilling of 28 gross (18.4 net wells) and completing of 26 gross (18.4 net) Kodiak-operated wells.  Kodiak has allocated $10 million to the building of infrastructure for gathering systems and facilities.

Gross per-well investment for a 10,000-foot horizontal lateral well drilled in either the Bakken or Three Forks is projected to be $8 million to $9 million to drill, complete, equip and connect to pipeline infrastructure.  The Company has scheduled delivery of its third operated rig for January 2011, which is expected to allow the Company to accelerate the development of its properties.  The 2011 Capex includes three Kodiak-operated drilling rigs with a 38% to 100% working interest range for the operated wells.  Kodiak’s 2011 drilling program, the largest in Company history, was designed to provide flexibility in identifying suitable well locations and in the timing and size of capital investment.

Also included in the 2011 Capex is an estimated $40 million allocated to non-operated drilling activity, primarily in the Company’s Area of Mutual Interest (AMI) with ExxonMobil Corporation located in Dunn County, N.D.  Based upon current information, Kodiak anticipates that approximately 10 gross (5.0 net) wells will be drilled in the AMI in 2011 utilizing one drilling rig.  Kodiak’s non-operated working interest in the AMI is expected to range from 40% to 50%.

The Company has not allocated any Capex for drilling and completion activity in the Vermillion Basin in Southwestern Wyoming.  Kodiak has a non-operated working interest in 40,600 gross acres (8,800 net acres) in this prospect area that is prospective for the Baxter Shale, a 3,000-foot-thick, condensate and gas-prone interval that is also referred to as the Niobrara Shale in other parts of Wyoming and Colorado.  During 2010, Kodiak participated in the drilling and completion of a well operated by Devon Energy in the Vermillion Basin.  The well has been turned to production facilities and is currently being evaluated.    Kodiak’s participation in future wells is subject to additional results from the recently completed well and to prevailing Rocky Mountain liquids and natural gas prices at time of election.

Kodiak’s preliminary 2011 Capex budget is subject to market conditions, oilfield services and equipment availability, commodity prices and drilling results.  Although potential leasehold acquisitions are not included in the preliminary Capex, the Company intends to continue to opportunistically add acreage in its core areas.

Kodiak expects to substantially fund the budget primarily from cash on hand, cash flow from operations and potential borrowings under its senior secured revolving credit facility, as well as from the anticipated proceeds from the offering of common shares announced today by the Company.  As the Company successfully drills and completes wells during 2011, it expects that the borrowing capacity available under its revolving credit facility will expand, subject to the results of the regularly scheduled redeterminations contemplated by the revolving credit facility.

Based on 2010 results and the 2011 Capex budget, Kodiak expects to average 5,500 to 6,500 BOE per day in production for 2011 and exit 2011 at a production rate of 9,000 BOE per day or more, assuming commodity prices and service costs remain consistent.

Management Comments

Commenting on the 2011 Capex, Lynn Peterson, Kodiak’s CEO and President said:  “The 2011 Capex represents the largest projected investment in Company history.  We believe that the Bakken program, characterized by low geological risk, remains a strong rate-of-return project for our invested capital with current commodity prices. The addition of the third operated drilling rig allows for the acceleration of our development drilling activity, including wells to be drilled on our recently acquired lands, which is expected to increase our operating cash flow with each new successful producer that we complete.  In addition, we anticipate steady activity from ExxonMobil in our Dunn County AMI with their drilling program.

“Our third quarter wells, which continue to reflect the benefits of improved completion techniques, gave us further reason to move ahead with the 2011 Capex.  The MC #13-34-28-1H and the MC #13-34-28-2H have demonstrated 90 day average production of 1,012 and 932 BOE per day, respectively, and continue to demonstrate the resource potential of our acreage.”

“Optimization of well bore density, maximizing completion results and containing well costs will continue to be our focus in 2011.  The wells that we are currently completing on our four-well pad should yield important results that will help us exploit the full potential of the Bakken and Three Forks reservoirs.  As noted earlier, we have not included capital expenditures for acreage acquisition.  However, as we move through the year, we will continue to look to acquire bolt-on leasehold that can help boost our drilling inventory, similar to our successful 2010 transactions.”
