FRISCO, Texas, Jan. 22, 2013 /PRNewswire/ -- Comstock Resources, Inc. ("Comstock" or the "Company") (NYSE:CRK) announced today that its proved oil and natural gas reserves as of December 31, 2012 were estimated at 39 million barrels of crude oil and 477 billion cubic feet ("Bcf") of natural gas or 712 billion cubic feet of natural gas equivalent ("Bcfe") as compared to total proved reserves as of December 31, 2011 of 1,311 Bcfe. The Company's proved oil reserves increased 22% in 2012 and now comprise 33% of total reserves as compared to 2011 when they represented only 15% of the total proved reserves. 62% of the proved reserves at December 31, 2012 were classified as proved developed, and 90% are operated by Comstock. The present value, using a 10% discount rate, of the future net cash flows before income taxes of the proved reserves (the "PV 10 Value") was approximately $1.0 billion, using average 2012 prices of $2.84 per Mcf for natural gas and $94.61 per barrel for oil. The average natural gas prices used to estimate the December 31, 2011 proved oil and natural gas reserves was $4.18 per Mcf. The substantially lower natural gas price in 2012 caused most of the Company's undeveloped Haynesville shale and Cotton Valley natural gas reserves to be uneconomic to drill and accordingly they are excluded from the yearend 2012 proved reserve estimates.
In 2012 Comstock produced 96.3 Bcfe or 263 million cubic feet equivalent ("MMcfe") per day. Production in 2012 increased by 1% from production in 2011. Oil production grew 175% in 2012 to 2.3 million barrels and natural gas production decreased by 9% to 82.5 Bcf. Oil made up 14% of 2012's total production as compared to only 5% in 2011. Production in the fourth quarter of 2012 was 21.3 Bcfe or 231 MMcfe per day. 16% of production in the fourth quarter of 2012 was crude oil and 84% was natural gas. Comstock's oil production in the fourth quarter of 6,099 barrels per day was negatively impacted by approximately 750 barrels per day. The short fall related to the shut-in of Eagle Ford shale wells during the quarter for fracing operations by Comstock and offset operators and for artificial lift installation. The Company's West Texas production was also negatively impacted by artificial lift issues. Horizontal drilling activity in West Texas and pad drilling in the Eagle Ford shale were already expected to limit oil production growth in the fourth quarter due to the small number of wells coming on line in the quarter.
Comstock's successful Eagle Ford shale drilling program in South Texas and its Wolfbone drilling program in West Texas were the primary drivers of the growth in crude oil production and crude oil proved reserves in 2012. Comstock's successful drilling program in the Eagle Ford shale in South Texas added 11.9 million barrels of oil and 7.5 Bcf of natural gas or 13.2 million barrels of oil equivalent to proved reserves in 2012. The West Texas drilling program contributed 5.4 million barrels of oil and 9.5 Bcf of natural gas or 6.9 million barrels of oil equivalent to proved reserves in 2012. Activity in the Haynesville shale and other regions added 14.0 Bcf of proved natural gas reserves in 2012.
With the continued low natural gas price environment, Comstock expects the fourth quarter 2012 financial results to include an impairment charge of approximately $78.6 million ($51.1 million after tax or $1.10 per share) related to unevaluated leases which are not expected to be developed prior to their expiration and certain developed natural gas properties.
