Energen Resources Closes Carracas Canyon Acquisition.

BIRMINGHAM, Ala. -- Energen Corporation (NYSE: EGN) announced today that its oil and gas exploration and production unit, Energen Resources Corporation, last week closed on its purchase of an estimated 30 billion cubic feet (Bcf) of proved and probable natural gas reserves in Carracas Canyon in the San Juan Basin from Dominion Resources Inc.

The San Juan Basin is home to Energen Resources' largest base of proved and unproved reserves, and this $30 million acquisition in the over-pressured Fruitland Coal is expected to contribute further to the Company's prospects in this region from the drilling of horizontal wells and sidetracks.

Approximately 22 percent of the acquired reserves are currently producing, approximately 51 percent are behind-pipe or proved undeveloped, and the remaining 27 percent are classified as probable reserves. Energen Resources estimates that future development costs will total approximately $23.5 million.

"This is a great 'tuck' acquisition for Energen Resources," said James McManus, president of Energen and Energen Resources. "We are very excited about the success we have had with horizontal drilling in the over-pressured Fruitland Coal; in addition, recent success with drilling sidetracks in this region proved up almost 3 Bcf of reserves in this acquisition in the weeks between the signing of the purchase-and-sale agreement and last week's close."

"This acquisition brings to a close a highly successful 2006, and we are looking forward to the start of what should be another record earnings year for Energen," said Mike Warren, Energen's chairman and chief executive officer. "Some 70 percent of our estimated production in 2007 is already hedged, and that factor alone removes a great deal of uncertainty associated with our earnings potential."

Average oil and gas revenues per unit of production for ERC's production associated with NYMEX contracts as well as for unhedged production will reflect the impact of basis differentials. Average NGL revenue per unit of production will be net of transportation and fractionation fees.

For production associated with basin-specific contracts, ERC will receive the contracted hedge price. Energen typically hedges basis differentials where applicable. In the tables above, the basin-specific contract prices were converted for comparability purposes to a NYMEX-equivalent price by adding to them ERC's assumed basis differentials.
