Rex Energy Announces Warrior South Well Results

STATE COLLEGE, Pa., March 18, 2013 (GLOBE NEWSWIRE) -- Rex Energy Corporation (Nasdaq:REXX) today announced initial results from its first three Warrior South Prospect wells in the Ohio Utica.

The Guernsey 2H, located in Noble County, Ohio, tested at a peak 24-hour rate of 3,111 Boe/d (39% NGLs, 43% gas, 18% condensate), assuming full ethane recovery and a natural gas shrink of 20%. The well produced with an average casing pressure of 2,229 psi during the initial 24-hour test period on a 30/64 inch choke. The well was drilled to a total measured depth of approximately 12,097 feet with a lateral length of approximately 3,640 feet and was completed in 23 stages. Based on composition analysis, the gas being produced is approximately 1,207 BTU.

The Guernsey 1H, located in Noble County, Ohio, tested at a peak 24-hour rate of 2,968 Boe/d (39% NGLs, 43% gas, 18% condensate), assuming full ethane recovery and a natural gas shrink of 20%. The well produced with an average casing pressure of 2,682 psi during the initial 24-hour test period on a 24/64 inch choke. The well was drilled to a total measured depth of approximately 11,963 feet with a lateral length of approximately 3,587 feet and was completed in 23 stages. Based on composition analysis, the gas being produced is approximately 1,216 BTU.

The Noble 1H, located in Noble County, Ohio, tested at a peak 24-hour rate of 2,938 Boe/d (41% NGLs, 45% gas, 14% condensate), assuming full ethane recovery and a natural gas shrink of 20%. The well produced with an average casing pressure of 2,562 psi during the initial 24-hour test period on a 24/64 inch choke. The well was drilled to a total measured depth of approximately 11,740 feet with a lateral length of approximately 3,378 feet and was completed in 21 stages. Based on composition analysis, the gas being produced is approximately 1,216 BTU.
