The Barnett Shale: From problem formulation to risk management

摘要: Abstract There is a nationwide trend to develop shale formations due advances in horizontal drilling and hydraulic fracturing technology. The Barnett Shale north Texas one of the largest onshore natural gas fields US, has experienced exponential growth since 1990’s. This immense amount well development production occurred near heavily populated, urban areas, leading increased public concern regarding impacts these activities on human health welfare. Commission Environmental Quality (TCEQ) charged with regulating sources air emissions from operations (NGOs) unique position evaluate any associated risks. goal this manuscript describe problem formulation process used by TCEQ characterize risks NGOs, subsequent risk management strategies implemented. Details how potential were identified quantified are provided. Initial assessments volatile organic compounds (VOCs) as chemicals concern. Over 4.7 million data points for VOCs assessment both short-term long-term basis. Only three samples measured above health-based monitoring comparison values (AMCVs). Several odor-based AMCVs. Long-term VOC levels below We efforts engage stakeholders early outreach programs used. Finally, details new rules regulations that being more efficiently manage Given resources experience possesses environmental may be caused production, it our hope serve resource others identify oil their area.
