Reserve Information

At December 31, 2001, we had an estimated net proved reserves of 53.4 Bcfe. We own approximately 73% of these reserves directly and 27% through our managed grilling programs. Based on average prices of $1.76 per Mcf of natural gas and $13.87 per Bbl of oil, the present value of estimated future net revenues (“PV-10”) was approximately $20 million. At December 31, 2001, our drilling programs had 59.2 Bcfe of estimated proved reserves with a PV-10 value of $35 million, excluding our interests in these programs. Based upon average realized prices on March 31, 2002 of $2.18 per Mcf of natural gas and $20.45 per Bbl of oil, the PV-10 of our proved reserves were approximately $49 million and our drilling programs were approximately $58 million.

At March 31, 2002, we had estimated net probable reserves of 128.5 Bcfe, which had a PV-10 value of $139 million. This was based on an evaluation of only 10% of our coalbed methane holdings in the Washakie Basin in Wyoming. In addition, we believe a significant number of natural gas and oil reserves potentially exist in our properties, which is based upon preliminary test data from the Atlantic Rim Project and Wilmington field in the Los Angeles Basin in California.

The following table sets forth summary data with respect to our proved, probable and possible natural gas and oil reserves and the combined reserves of Warren and our drilling programs as of December 31, 2001, using non-escalated pricing at March 31, 2002.

As of December 31, 2001, we had interests in 231 producing wells and were the operator of 64% of these wells. As of the same date, the daily gross production of these wells was 33.8 Mmcfe, of which 12.8 Mmcfe was attributable to Warren (38%) and its drilling programs (62%). Although Warren was entitled to a percentage of production, due to production subordination agreements with our drilling programs substantially all production was allocated to investors in our drilling programs. Commencing July 1, 2001, 25% of new production from interests in wells owned by the drilling programs formed in 1999 and subsequent years is being directly allocated to us pursuant to governing agreements with our drilling programs.

Our exploration and development is focused on:

  • coalbed methane in Wyoming and other Rocky Mountain areas; and
  • waterflood redevelopment with directional drilling in the Wilmington Field in California.
