Chaparral Energy Announces Year-End Reserves and Reaffirms 2009 EBITDA Guidance

OKLAHOMA CITY, February 8, 2010 – Chaparral Energy, Inc. (“Chaparral”) today announced year-end 2009 reserves and reaffirmed 2009 EBITDA* guidance.

Year-End 2009 Reserves

As of December 31, 2009, using new pricing methodology required by the U.S. Securities and Exchange Commission (the “SEC”), Chaparral reported total reserves of 141.9 million barrels of oil equivalent (MMBOE) with a PV-10 value of $1.3 billion. This compared with 113.3 MMBOE of reserves at the end of 2008, or about a 25% increase.

The Company’s proved reserves are summarized in the table below.

As of December 31, 2009

Classification of Reserves Oil (MMBbls) Gas (Bcf) Total (MMBOE) % Oil % of Total Proved PV-10 (In Millions)
Proved Developed Producing 40.8 183.1 71.3 57% 50% $813.4
Proved Developed Non-Producing 15.1 44.9 22.6 67% 16% $180.2
Total Proved Developed 55.9 228.0 93.9 60% 66% $993.6
Proved Undeveloped 33.6 86.4 48.0 70% 34% $329.9
Total Proved 89.5 314.4 141.9 63% 100% $1,323.5

In accordance with guidelines recently established by the SEC, our proved reserves as of December 31, 2009 were determined to be economically producible under existing economic conditions, which requires the use of the 12-month average price for each product, calculated as the unweighted arithmetic average of the first-day-of-the-month price for the period January 2009 through December 2009. Utilizing this approach, the present value of our total proved reserves discounted at 10% (PV-10) were based on average prices of $3.87 per Mcf for natural gas and $61.18 per Bbl for oil.

Previously, SEC guidelines required that reserves be valued at the market price on the last day of the reporting period. For comparative purposes, under the old pricing methodology which would have utilized December 31, 2009 prices of $5.79 per Mcf for natural gas and $79.36 per Bbl for oil, total reserves at the end of 2009 would have been 157.8 MMBOE, with a PV-10 value of $2.2 billion

2009 EBITDA – Chaparral continues to expect EBITDA for 2009 to be between $220 million and $225 million, as previously forecasted.

*EBITDA, or earnings before interest, taxes, depreciation and amortization, is a non-GAAP term. EBITDA is used as a supplemental financial measurement in the evaluation of our business and should not be considered as an alternative to net income, as an indicator of our operating performance, as an alternative to cash flows from operating activities, or as a measure of liquidity.
