Energen Corporation (NYSE: EGN) today said the 54-day performances of its first two Lower Spraberry wells in Martin County (results disclosed May 6, 2015) -- the Campbell #501H and the Wilbanks SN 16-15 #501H -- are tracking above a 900 MBOE EUR type curve and a 1,200 MBOE EUR type curve, respectively. The 1,200 MBOE curve supports an internal rate of return of 110 percent and a PV10 value of $13.3 million; the 900 MBOE curve supports an IRR of 60 percent and a PV10 value of $8.3 million.

This information is shown in a graph included in the company’s new May 2015 investor slide presentation that has been posted to its website (see www.energen.com, Webcasts and Presentations).

The graph plots the oil portion of the 54-day, 3-stream production history (from first oil) of its first two Martin County Lower Spraberry appraisal wells relative to potential type curves representing EURs of 770 MBOE, 900 MBOE, and 1,200 MBOE. The potential, three-stream type curves and production history have been normalized to a 7,500’ lateral length; actual lateral lengths will vary. The economics of the type curves are based on flat oil, natural gas liquids, and natural gas prices of $60/barrel WTI, $22.20/barrel, and $4/Mcf NYMEX, respectively, and assume drill-and-complete costs of $6 million per well.

Energen Corporation is an oil and gas exploration and production company with headquarters in Birmingham, Alabama. The company has 1.1 billion barrels of oil-equivalent proved, probable, and possible reserves at year-end 2014 and another 2.2 billion barrels of oil-equivalent contingent resources.
