Barnett Shale Geological Area

Barnett Shale is a hydrocarbon-producing geological formation consisting of sedimentary rocks and stretching from the Dallas–Fort Worth metroplex west and south, covering 5,000 square miles.

Background

Since 2002, gas production activity in the area has experienced significant growth and the TCEQ has been improving emissions data from oil and gas production and is conducting in-depth measurements to fully evaluate potential health effects.

TCEQ is using state-of-the-art technology to address emissions from Barnett Shale activities and overall oil and gas operations. These initiatives will continue to reduce emissions through improved agency policies, guidance for regulated entities and possible enforcement if necessary.
