Pursuant to Senate Bill 4 (Pavley 2013), the California Natural Resources Agency commissioned the California Council on Science and Technology (CCST) to conduct an independent scientific assessment of well stimulation treatments, including hydraulic fracturing, in California.
The purpose of the report is to synthesize and assess the available scientific information associated with well stimulation treatments (WST) in California. The review will survey hydraulic fracturing, matrix acidizing, and acid fracturing as they are applied both onshore and offshore for oil and gas production in the state. The study workscope is organized in three major areas, which are being documented in three separate report volumes.
Volume II discusses how well stimulation could affect water, atmosphere, seismic activity, wildlife and vegetation, and human health. Volume II reviews available data, and identifies knowledge gaps and alternative practices that could avoid or mitigate these possible impacts. For more information on this project, click here.
