Eagle Ford

Eagle Ford Shale Description ImageThe Eagle Ford shale formation in South Texas runs from the US-Mexico border north of Laredo in a narrow band extending northeast for several hundred miles to just north of Houston. It is located directly below the Austin Chalk. The average thickness of the Eagle Ford shale is about 475 feet. The more active part of the region is mainly in McMullen, Maverick, Dimmit, La Salle, Karnes, Live Oak, and Atascosa counties. The formation produces both natural gas and oil, but it is the oil-producing and gas condensate areas that are hottest right now.

Houston-based Apache Corp. and EOG Resources are two of the largest lease-holders in the Eagle Ford. Other major players include Petrohawk, Swift Energy, ExxonMobil, ConocoPhillips, Murphy Oil, Chesapeake, Cabot Oil & Gas, and Pioneer Natural Resources.

LOUISIANA HORIZONTAL WELL TAPS OIL IN AREA OF SALT RELATED FRACTURING

Jul 6, 1992 James H. Skelton Independent Geologist Houston The successful drilling and completion of the world's deepest horizontal well in Louisiana confirms seismic indications that the brittle Upper Cretaceous Austin chalk has been highly fractured by nearby halokinetics (salt movement). Cliffs Oil & Gas Co., Houston, 1-A Roy Martin in Avoyelles Parish flowed 2,566 b/d of oil from the chalk at a true vertical depth of 15,339 ft. Previous studies of fractured formations have identified two types of

New method of aerial and surface radiometric prospecting for oil, gas

Sep 20, 1993 Mean Natural Radioelement Content of Sedimentary Rocks [34,614 bytes] A new petroleum exploration method has been developed using surface and aerial gamma-ray spectral measurements. Formerly troublesome lithologic and environmental variables are suppressed by correcting potassium and uranium readings using a process of thorium normalization.
