NEW PERMIAN ACQUISITIONS BOOST ENERGEN’S 2011 CAPITAL SPENDING PLANS

Oil, NGL Production Estimated to Grow 20% in 2011

2011 Earnings Guidance Increased

BIRMINGHAM, Alabama – Energen Corporation (NYSE: EGN) announced today that it has increased its 2011 capital spending plans, production estimates, and earnings guidance range to reflect the first-year impact of its two latest Permian Basin acquisitions: (1) a Wolfberry package expected to close this month and (2) a Bone Spring acreage package that closed today.

The diversified energy company is increasing its capital spending plans at Energen Resources Corporation, its oil and gas exploration and production business, to a record $667 million (prior 2011 guidance was for $510 million). Of this amount, more than 80 percent will be deployed in the oil-rich Permian Basin. Reflected in the company’s new capital budget are an additional 56 Wolfberry wells and another 8 Bone Spring wells. Energen Resources also has added capital for additional drilling rigs in the Permian Basin; the company expects to run 14-15 rigs in 2011, up from approximately 6-8 rigs in the prior guidance.

The company’s production forecast for 2011 is now 123 billion cubic feet equivalent (Bcfe), reflecting 9 percent growth over its 2010 estimated production (prior 2011 production guidance was 120 Bcfe). Oil and natural gas liquids (NGL) production is expected to jump 20 percent from 2010 to 2011 and comprise more than 40 percent of total estimated production.

Given the significant drilling inventory and limited current production of Energen Resources’ latest Permian Basin acquisitions, associated production in 2011 will be relatively modest; however, Permian production is expected to grow substantially over the next 4-5 years. Based on the pace of development drilling and the risking incorporated into its acquisition models, Energen Resources’ oil and NGL production could increase approximately 60 percent from 2010 to 2013.

As a result of changes to its 2011 production estimates, Energen is revising upward its earnings guidance by 5 cents to $3.25-$3.65 per diluted share; this guidance also reflects an expected increase in interest expense associated with the potential issuance of long-term debt to help finance recent acquisitions.

CAPITAL SPENDING IN 2011

Oil and natural gas liquids in the Permian Basin will, once again, be the focus of Energen Resources’ capital plans given the strength of oil prices relative to natural gas.

Development Drilling: Net Wells by Area

Energen Resources also plans to invest $25 million for exploratory drilling in the Permian Basin in 2011.

2011 EARNINGS GUIDANCE

Energen’s new earnings guidance range for 2011 is $3.25-$3.65 per diluted share. The company also increased its 2011 after-tax cash flow estimate to $643-$672 million. Energen’s guidance assumptions for commodity prices remained unchanged at $4.25 per thousand cubic feet (Mcf) for natural gas, $80 per barrel for oil, and $0.83 per gallon for NGL. Energen also has added oil and natural gas hedges for 2011. Approximately 63 percent of the company’s 2011 estimated production is now hedged at an average NYMEX-equivalent price of $8.72 per Mcfe.

Other key assumptions in Energen’s 2011 guidance include:

Sensitivity of 2011 Earnings, Cash Flows to Changes in Commodity Prices

Given Energen Resources’ current hedge position for 2011, changes in commodity prices are estimated to have the following impact on Energen’s 2011 earnings and cash flows:

Price-related events such as substantial basis differential changes could cause earnings sensitivities to be materially different from those outlined above.

HEDGE POSITIONS STRENGTHENED IN 2012-2014

In recent weeks, Energen Resources has sold additional swaps for a portion of its oil production in 2012, 2013, and 2014.

Energen Resources’ hedge position for 2012 is as follows:

Energen Resources’ oil hedge position by hedge type for 2012 is as follows:

Energen Resources’ oil hedge positions in 2013 and 2014 are as follows:

Average realized oil and gas prices for Energen Resources’ production associated with NYMEX contracts as well as for unhedged production will reflect the impact of basis differentials. Average realized NGL prices will be net of transportation and fractionation fees. For production associated with basin-specific contracts, Energen Resources 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 Energen Resources’ assumed basis differentials.
