A. W. Gregg v. Delhi-Taylor Oil Corporation

A. W. Gregg is the owner of an oil and gas lease on .42 acres in the City of Pharr, Hidalgo Colnty, Texas. The tract is approximately 75 feet wide. Delhi-Taylor Oil Corporation and Mayfair Minerals, Inc., (herein called Delhi-Taylor) own the mineral estates in lands surrounding Greggs lease. Gregg is drilling a well 37-1/2 feet from Delhi-Taylors lease on the east and 80 feet from its south line. He plans to increase the productivity of his well by fracturing the gas-producing formation, a process by which sand is mixed with liquid and forced into the structure under great hydraulic pressure. Veins or cracks are thus opened so that the gas may flow from the producing rock or sand into Greggs well. Delhi-Taylor brought this suit to enjoin Gregg from fracturing the common formation beyond Greggs own property lines and into Delhi-Taylors lease. It is a suit by Delhi-Taylor to enjoin a subsurface trespass by Gregg.
