Exploring Horizontal Drilling and Its Controversies in the Eagle Ford Shale Region

This video delves into the complexities and controversies surrounding horizontal drilling in the Eagle Ford Shale. It covers critical issues such as methane contamination of water wells, water consumption, groundwater contamination from hydraulic fracturing (HF), emission impacts, and more. Additionally, we discuss community effects, traffic increases, health impacts, and economic repercussions stemming from the shale gas boom. This comprehensive overview aims to provide insights into the environmental and societal challenges posed by the oil and gas industry.

  2. Eagle Ford Shale

  3. (Hint: There Are a Few) Controversies

  4. Shale Gas & Oil Controversies • Methane in water wells • Water consumption • Groundwater contamination by HF • Fracture fluid additives • Surface spills at well pads • Well blowouts • Induced seismic effects • Flowback and produced water management • Deep injection well disposal • Atmospheric emissions • Health impacts • Methane emissions, greenhouse gas issues • Community impacts

  5. Community Impacts: A Partial List • Atmospheric emissions & health impacts • Increased traffic • Impacts on roads • Increased noise • Aesthetic effects – short and long term • Need for well pad setbacks • Economic impacts (beneficial) • “Energy boom” effects • Population growth - outpacing infrastructure • Home value & rent increases • Emergency services • Health care • School populations
