HOUSTON, Dec. 10 -- Pioneer Natural Resources Inc., Dallas, is drilling the horizontal leg in Cretaceous Eagle Ford shale at an exploratory well in DeWitt County, Tex.

This is about 90 miles east-northeast of where Petrohawk Energy Corp., Houston, gauged an Eagle Ford gas-condensate discovery in LaSalle County (OGJ Online, Oct. 21, 2008).

Petrohawk is completing its second well in LaSalle and is drilling in McMullen County, Pioneer said.

Pioneer has logs through Eagle Ford from the more than 150 wells it has drilled in the Cretaceous Edwards Trend along its 310,000-acre spread from LaSalle to Lavaca counties and chose to horizontally drill the Eagle Ford where it saw the best porosity. Permeability is the question, the company said Dec. 2.

Eagle Ford shale is the source rock for the Cretaceous Austin chalk and Edwards formations, Pioneer noted.

Meanwhile, the company's Edwards gas production is averaging 85 MMcfd.
