Pittsburgh-based Mountaineer Keystone, a pure play natural gas operator in the Marcellus, has changed its name to Arsenal Resources effective Feb. 21.

Arsenal Resources is the fourth-largest contiguous pure play natural gas acreage holder in the West Virginia Core. It combines drilling and completion technologies with a fully integrated midstream development plan.

"It is our people and our assets that together are our greatest competitive strength, and our rebranding underscores this,” Dave Wood, chairman and CEO of Arsenal Resources, said in a statement. “We are strategically focused on pure play, dry natural gas assets in the Southern Appalachian Basin and have built a culture and acreage position that is poised for strong growth. Arsenal Resources, as a brand, reflects this strength and bright future."

The company will continue its full and complete transition to the name Arsenal Resources in the coming weeks. As part of the rebranding, the company has also changed its primary website URL to arsenalresources.com.
