The Barnett Shale: from problem formulation to risk management

The Barnett Shale: from problem formulation to risk managementExit the TCEQ has been published in the Journal of Unconventional Oil and Gas Resources and is now available: the TCEQ.

This peer-reviewed publication describes in detail the problem formulation process used by the TCEQ to identify and quantify risks associated with air emissions from natural gas operations in the Barnett Shale area and the subsequent risk management strategies implemented. Our hope is that this manuscript may serve as a resource to others to identify and manage risks in other shale plays. For more information about this publication, you may e-mail us at
