Assessment of Potential Impacts of Hydraulic Fracturing in California Released

On July 9, 2015, the California Council on Science and Technology (CCST) released the last two volumes of an independent assessment of well stimulation, including hydraulic fracturing, in California.. Volumes II and III are respectively entitled “An Examination of Hydraulic Fracturing and Acid Stimulations in the Oil and Gas Industry” and “Case Studies of Hydraulic Fracturing and Acid Stimulations in Select Regions: Offshore, Monterey Formation, Los Angeles Basin, and San Joaquin Basin.”

CCST previously published Volume I of the independent assessment, entitled “Well Stimulation Technologies and their Past, Present, and Potential Future in California”, in January 2015. This independent assessment was made pursuant to Senate Bill No. 4’s mandate to establish a legal framework for unconventional well stimulation techniques.

According to Volume II, most of the impacts related to hydraulic fracturing are caused by “indirect impacts”, meaning “not directly attributable to” hydraulic fracturing operations. The authors defined “indirect impacts” as “impacts caused by additional oil and gas development enabled by well stimulation.” The study also points out that hydraulic fracturing accounts for 90% of all well stimulation in California.
