CNX Resources Corp., Pittsburgh, said it remediated the Shaw 1G well in Washington Township, Westmoreland County, Pa., “to arrest a subsurface flow of gas.”
The operator responded to a pressure anomaly observed while it was hydraulically fracturing the Utica shale well during the last week of January.
It reported successful completion of the remediation on Feb. 5 and said the well had been contained with no injuries or environmental effects.
It suspended fracturing on the four-well pad from which the well was drilled and said it was monitoring the Shaw 1G and nearby wells.
“While we continue to evaluate the cause of the initial pressure anomaly, we believe it is isolated to this well,” the company said.
