EIA Cuts Monterey Shale Estimates on Extraction Challenges

The Energy Information Administration slashed its estimate of recoverable reserves from California’s Monterey Shale by 96 percent, saying oil from the largest U.S. formation will be harder to extract than previously anticipated.

“Not all reserves are created equal,” EIA Administrator Adam Sieminski told reporters at the Financial Times and Energy Intelligence Oil & Gas Summit in New York today. “It just turned out it’s harder to frack that reserve and get it out of the ground.”
