HOW MUCH WATER IS USED?
“An Independent Scientific Assessment of Well Stimulation in California”, January 2015 Could WST allow production of unconventional resources? Unconventional oil in deeper, low permeability source rocks – Monterey Formation – Soda Lake Shale, Vaqueros Formation – Tumey Formation – Kreyenhagen Formation – Moreno Formation San Joaquin Basin – Monterey data from Magoon et al., 2009
“An Independent Scientific Assessment of Well Stimulation in California”, January 2015 Current technology could add 4.9 to 15.6 billion barrels from just 19 giant San Joaquin and L.A. basin fields, with WST use much as it is today, i.e., mostly in SJV USGS Fact Sheet 2012–3120; USGS Fact Sheet 2012–3050
