Wilson County, TX and the Eagle Ford Shale Play

Wilson County Eagle Ford Shale Map

Wilson County (809 sq miles) is in the liquids-rich Eagle Ford Shale Play of  South Texas. Generally, drilling activity targets the oil window of the Eagle Ford in the southeastern half of the county where well economics are enhanced by the production of oil. The formation is found at depths between 4,000 ft and 8,000 ft as you move southeast through the county.  The deeper portions of the county are considered more prospective as the formation is also thicker in this area of the play.

The county's oil and gas production previously exploited the Austin Chalk and conventional formations, but recent activity has shifted to the Eagle Ford Shale Oil Play.

County services of interest to oil and gas lease owners include the Wilson County Appraisal District (tax collector) office and the Wilson County Clerk (property records) office. The county is approximately 35 miles southeast of San Antonio, TX, and the county seat is the town of Floresville. Other towns in Wilson County include Carpenter, La Vernia, Nixon, Pandora, Poth, Saspamco, Stockdale, Sutherland Springs, Grass Pond Colony, Kicaster, Doseido Colony, and Sandy Hills.
