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.
