The recent growth in unconventional oil production from the Bakken (North Dakota), Eagle Ford (Texas) and other tight oil plays has drawn attention to the potential of shale in California’s Monterey Formation. Commercial oil production from the Monterey Formation is not new—more than a billion barrels of oil and four trillion cubic feet of gas have been produced from it since 1977, largely from conventional reservoirs. However, completion techniques like hydraulic fracturing which have made tight oil production possible from shale deposits elsewhere have not yet been widely implemented in the shale source rocks of the Monterey Formation.
In 2011, the U.S. Energy Information Administration (EIA) published a report by INTEK Inc. which stated that the Monterey Formation contains 15.4 billion barrels of technically recoverable tight oil (therein referred to as "shale oil") —64 percent of the entire estimated tight oil resource in the Lower-48 United States at that time. This estimate was seized upon by industry groups intent on the development of the Monterey shale, and was used as the basis of a March 2013 University of Southern California (USC) economic analysis which projected as much as a $24.6 billion per year increase in tax revenue and 2.8 million additional jobs by 2020. It also raised alarm among groups concerned about the environmental and public health implications of hydraulic fracturing, acidization, and other advanced well stimulation technologies.
This report provides the first publicly available empirical analysis of oil production data from the Monterey Formation, utilizing the Drillinginfo database (widely used by the oil and gas industry as well as the EIA). It lays out some of the fundamental characteristics of the Monterey compared to other tight oil plays, including geological properties, current production, and production potential. The results of this analysis will be useful for informing public policy decisions surrounding the development of the Monterey shale.
