UNIT ANNOUNCES COMPANY-RECORD 2007 CAPITAL EXPENDITURE BUDGET
AND PROVIDES OPERATIONS UPDATE

Tulsa, Oklahoma….Unit Corporation (NYSE - UNT), a diversified energy company with a
consistently growing exploration and production asset base, one of the largest onshore drilling fleet
operating in the U.S., and a rapidly expanding midstream business unit, today announced its planned 2007
operating capital budget of $482 million, the largest in the Company’s 45-year history, and certain 2006
operating results of its wholly owned subsidiaries.

Unit Petroleum Company
Unit Petroleum Company has budgeted capital expenditures of $326 million, excluding
acquisitions, for 2007, of which $280 million is planned for exploration and development drilling. This
budget represents a 37% increase over the company’s estimated 2006 capital expenditures, excluding
acquisitions. At the end of 2006, Unit Petroleum had spud 248 new wells and had completed drilling
operations on 233 of those wells. In addition, 11 wells were completed in 2006 that were spud in 2005
for a total of 244 completed wells. Of the 244 wells, 214 were completed as producing for a success rate
of 88%.

The company currently plans to participate in the drilling of 270 wells during 2007, an increase of
11% over 2006. Although the Company does not provide quarterly production forecasts, Unit’s
preliminary 2007 annual guidance is approximately 60.0 billion cubic feet equivalent. The Company’s
long-time stated goal is to replace each year a minimum 150% of its production through drilling and
strategic acquisitions, a goal which the Company has successfully met since 1984.

Unit Drilling Company
Unit Drilling Company has budgeted capital expenditures of $131 million for 2007, which
represents a decrease of 25% over estimated 2006 capital expenditures. Unit ended 2006 with a record
117 drilling rigs, having added six rigs to the fleet in 2006. The company recently completed the building
of its 117th drilling rig, a 750-horsepower, diesel electric rig, and is in the process of constructing two
additional drilling rigs that will be completed in the first quarter of 2007. Both of these new rigs will be
1,500 horsepower, diesel-electric drilling rigs and are already under contract. Of Unit’s current 117
drilling rigs, 110 are under contract. The company has enjoyed having its rigs at or above 90% utilization
for 12 consecutive quarters, which is above industry-average utilization rates for the drilling group.

Superior Pipeline Company
Superior Pipeline Company has budgeted capital expenditures of $25 million for 2007. During
2006, Superior completed the installation of a second natural gas treatment plant on the Panola gathering
system, acquired two natural gas processing plants to be installed on existing facilities, completed the
acquisition of an additional gathering system and processing plant and added an additional 100 miles of
pipeline. Currently, Superior's asset base consists of three natural gas treatment plants, six operated
natural gas processing plants, 37 active gathering systems and approximately 600 miles of pipeline. Also
during 2006, Superior connected an additional 58 wells to its gathering systems.

Management Comments
Larry Pinkston, President and Chief Executive Officer, said: “For the exploration and production
group, we have increased the number of wells we plan to drill this year by 11% and anticipate this to be a
positive impact to our operations. We are confident that our high-quality E&P asset base offers us
multiple ways to realize meaningful growth for our shareholders. During the period 2003 through 2005,
we increased our reserves 35% on a debt-adjusted per share basis, an excellent return when you consider
our third quarter 2006 debt-to-capitalization ratio of 12%. Our drilling operations remain very active,
despite the recent softening in commodity prices. We’re very pleased with how our drilling customers
continue to turn to Unit, which we believe is a testament to the quality of our rigs and people. We are
very excited about how Superior Pipeline continues to grow and add to its asset base. Superior is rapidly
establishing a significant operation in the Arkoma and Mid-Continent basins, two of America’s important
regional plays for meeting the growing need for natural gas. We look forward to announcing more 2006
results when they become available.”
