Recent documents, upcoming meetings and activities related to the Barnett Shale area.
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.
Number of producing wells in the Barnett Shale 23 county area:
Barnett Shale Formation Only: 11,627
All Formations including Barnett Shale Formation: 59,541
More information: annual well count 
Barnett Shale Area Special Inventory
The TCEQ is requesting companies with Barnett Shale oil and gas operations to provide air emissions-related information for calendar year 2009.
Health Effects Evaluations
Review and analysis of health effects based on air monitoring data.
Barnett Shale Emissions Data Collection and Analysis
TCEQ is increasing the understanding of air quality data through ground based monitoring and flyover surveys using infrared camera technology. Oil and gas calculation methods are also being studied to improve data on upstream oil and gas operations.
