EQT Corporation has reported an average 30-day production rate of 22mmcfe per day from the Cooper 590384, a Marcellus shale well in Greene County, Pennsylvania.

The direct well, which has a total lateral length of 9,000ft, with 8,411ft of stimulated pay, cost approximately $7.1m, with a preliminary estimated ultimate recovery of 18bcf. The well was completed using a 28-stage frac.

EQT also provided the successful results of the Rosborough 590259 well in Armstrong County, Pennsylvania, which reported a 24-hour IP of 15mmcfe from 4,060ft of stimulated pay.

EQT Exploration & Production president Steven Schlotterbeck said that 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.
