Is the Eagle Ford moving to the east?
Most of the Eagle Ford Shale activity has been concentrated in a cluster of South Texas counties, particularly crude-oil-rich Gonzales, Karnes, DeWitt, La Salle and McMullen, with companies focused on drilling those highly profitable areas as quickly as possible.
But oil and gas companies have also leased acreage and started drilling wells on the eastern edge of the trend closer to Austin and Houston where the Eagle Ford Shale meets the Woodbine Sandstone.
The so-called “Eaglebine” is generally described as anything located below the Austin Chalk and above the Buda Limestone, said Thomas Bowman, vice president of evaluation geology and geophysics with the Houston-based ZaZa Energy Corp. Bowman spoke Wednesday at a technology workshop for the American Association of Petroleum Geologists at the Hotel Contessa.
“We have been drilling wells and other people have as well,” Bowman said. “It is the extension (of the Eagle Ford Shale). It is the next thing.”
The Eaglebine includes both the Eagle Ford Shale and the Woodbine Sandstone, the reservoir famously drilled in the 1930s during the discovery of the giant East Texas Field.
Activity appears to be concentrated primarily in Brazos, Madison, Walker and Grimes counties.
