Rex probing Utica shale, other Devonian formations

Rex Energy Corp., State College, Pa., is pursuing liquids potential of several Devonian-age formations in Ohio and Pennsylvania, including the Utica shale, Upper Devonian Burkett shale, and the Upper Devonian Rhinestreet shale.

Rex spudded its second Utica shale well, Hufnagel-1H, in Butler County, Pa., in the quarter ended June 30 and expects to complete it in the first half of 2013, the company said in its second quarter report. The well reached total depth in July.

The company’s first Utica well in Butler County, Cheeseman-1H, tested at an initial 9.2 MMcfd and a 30-day rate of 5.3 MMcfd of gas, a 60-day rate of 4.1 MMcfd, and a 120-day rate of 3.7 MMcfd. It was placed in service in the quarter ended Mar. 31.

Rex plans to spud its second Burkett well by the end of 2012. Its first Burkett well, Gilliland-11HB, in Butler County, Pa., has a 2,700-ft lateral and has been shut-in since its initial test. Following the shut-in, the well produced at a restricted rate of 3.2 MMcfd of gas equivalent, which included 117 b/d of natural gas liquids and 4 b/d of condensate, or 23% liquids content excluding ethane.

Gilliand-11HB, on the same pad with five Marcellus shale wells, yielded 16% more liquids than Marcellus wells in the same area, the company said. With ethane extracted, the well is estimated to yield 335 b/d of liquids, and when condensate production is included along with the ethane, the liquids share would be an estimated 43% of the production stream.

Rex also plans to frac one of its legacy vertical wells to test the gas quality and liquids potential of the Rhinestreet formation.

Meanwhile, Rex plans to turn its first Ohio Utica shale well to sales in September 2012. The Brace-1H, in Carroll County, went to 12,332 ft measured depth including a 4,170-ft lateral. It has been shut-in since fracture stimulation in June 2012.
