Does the Bakken Formation contain more oil than Saudi Arabia?
Probably not. In 2000, the USGS assessed undiscovered, technically recoverable oil and gas in Saudi Arabia at 87 billion barrels (USGS 2000 World Petroleum Assessment ) compared to a mean estimate of undiscovered, technically recoverable oil in the Bakken formation of 7.4 billion barrels. In addition, Saudi Arabia contains even more oil that has already been found, which is reported by the U.S. Energy Information Administration as current proven oil reserves.
It is worth keeping in mind that there is no certain method to determine the exact volume of oil that is contained in the Bakken Formation or any formation. However, the estimate of technically recoverable oil in the Bakken Formation is larger than all other current USGS oil assessments of the lower 48 states and is the largest "continuous" oil accumulation ever assessed by the USGS. “Continuous” means that the oil is dispersed throughout a geologic formation rather than existing as a discrete, localized occurrence.

Characterization and origin of brines from the Bakken-Three Forks petroleum system in the Williston Basin, USA
Brine (also referred to as ‘produced water’) samples were collected from 28 wells producing oil from the Late Devonian-Early Mississippian Bakken and Three Forks Formations in the Williston Basin of eastern Montana and western North Dakota. The samples were analyzed for major ions, trace metals, stable isotopes, and strontium isotopes. The brines...

The U.S. Geological Survey (USGS) has completed an assessment of water and proppant requirements and water production associated with the possible future production of undiscovered oil and gas resources in the Three Forks and Bakken Formations (Late Devonian to Early Mississippian) of the Williston Basin Province in Montana and North Dakota. This...

Assessment of Undiscovered Technically Recoverable Oil and Gas Resources of the Bakken Formation, Williston Basin, Montana and North Dakota, 2008
The U.S. Geological Survey (USGS) has completed an assessment of the undiscovered oil and associated gas resources of the Upper Devonian to Lower Mississippian Bakken Formation in the U.S. portion of the Williston Basin of Montana and North Dakota and within the Williston Basin Province. The assessment is based on geologic elements of a total...

The Upper Devonian and Lower Mississippian Bakken Formation in the United States portion of the Williston Basin is both the source and the reservoir for a continuous oil accumulation - in effect a single very large field - underlying approximately 17,800 mi2 (46,100 km2) of North Dakota and Montana. Within this area, the Bakken Formation...

USGS Releases New Oil and Gas Assessment for Bakken and Three Forks Formations
On April 30, 2013, the United States Geological Survey (USGS) released an updated oil and gas resource assessment for the Bakken Formation and a new assessment for the Three Forks Formation in North Dakota, South Dakota and Montana. The assessments found that the formations contain an estimated mean of 7.4 billion barrels (BBO) of undiscovered, technically recoverable oil. The updated...

CRC, Core from Bakken Region
Researchers at the CRC can study cores from one area or compare cores from many different areas. This cross section is from the Bakken Formation, Williams, County, North Dakota. Since 2008 approximately 450 million barrels of oil have been produced from the Bakken and the underlying Three Forks Formation. In the 2013 assessment, the USGS estimated mean undiscovered volumes
