EQT Corp. on Wednesday reported double-digit initial production (IP) results for two of its newest natural gas wells in the Pennsylvania portion of the Marcellus Shale.

The Cooper 590384 well in Greene County, PA, had an average IP rate of 22 MMcfe/d over 30 days, the Pittsburgh-based producer said. The well, completed in late July, has a total lateral length of 9,000 feet, with 8,411 feet of stimulated pay, and was completed with a 28-stage fracture.

The direct well cost was about $7.1 million, with a preliminary estimated ultimate recovery of 18 Bcf, according to EQT.

The Rosborough 590259 well in Armstrong County, PA, had a 24-hour IP of 15 MMcfe from 4,060 feet of stimulated pay.

"The success of the Greene County extended lateral well is an important step in our effort to decrease the development cost per Mcfe," said Steven Schlotterbeck, who is president of EQT Exploration & Production. "In addition to extending the lateral, we are experimenting with closer spacing intervals than our current 1,000-foot lateral spacing design in Greene County.

"The results in Armstrong County, where EQT holds nearly 34,000 acres, are especially encouraging as this well employed a new completion design resulting in initial flow rates significantly better than nearby wells completed conventionally."

EQT holds a 100% working interest and an 87.5% net revenue interest in both wells.
