USGS har återigen nedgraderat de tekniskt utvinningsbara skifferoljereserverna i Kaliforniens Montereyformation och anger nu att man alltså om man struntar i lönsamheten eller tillgängligheten kan utvinna 21 miljoner fat skifferolja i delstaten.
"These new estimates are for technically recoverable oil and gas resources, which are those quantities of oil and gas producible using available technology and industry practices, regardless of economic or accessibility considerations."Postcarbon Insitute konstaterar att de påstådda reserverna nu gått från tre års amerikansk oljekonsumtion till 28 timmar.
"To put this in perspective a resource which in 2011 the EIA estimated was 15.4 billion barrels—enough oil to meet all of U.S. needs for nearly 3 years—has been reduced to 21 million barrels, or enough oil to meet U.S. needs for 28 hours. The initial estimate caused wildly overblown optimism within industry and government on the energy and economic future of California and major concerns within environmental groups about the effects of fracking to recover these resources on the environment."
