Houston-based Enervest paid Range Resources $876 million cash for the Nora, located along the border between West Virginia and Virginia.

The asset package includes 105 million cubic feet per day of dry gas production from more than 3900 wells spread across 365,000 net acres with a gathering system that stretches 1500 miles.

"This acquisition adds to EnerVest's significant position in Appalachia, and includes additional drilling opportunities at today's commodity prices," chief executive John Walker said.
