Last week the U.S. Geological Survey (USGS) provided an update of oil and gas resources in the Bakken region. This was their first update since a 2008 report that estimated mean undiscovered volumes of 3.65 billion barrels of oil and 1.85 trillion cubic feet of natural gas in the region. The new estimate includes the Three Forks formation which largely lies underneath the Bakken in the Williston Basin that sprawls across North Dakota, South Dakota, Montana, and southern Saskatchewan.
The new USGS assessment stated that the Three Forks formation had not been previously assessed, but that an assessment was warranted based on a rise in drilling and production in the formation. Inclusion of the Three Forks formation added an estimated mean resource of 3.73 billion barrels of oil to the estimated 3.65 billion barrels of oil in the Bakken formation for a total estimated resource of 7.4 billion barrels of undiscovered, technically recoverable oil in the two formations. The two formations were also estimated to contain a mean of 6.7 trillion cubic feet (tcf) of undiscovered, technically recoverable natural gas and 0.53 billion barrels of undiscovered, technically recoverable natural gas liquids (NGLs).
