3 to 4.3 Billion Barrels of Technically Recoverable Oil Assessed in North Dakota and Montana’s Bakken Formation—25 Times More Than 1995 Estimate
Released: 4/10/2008
Reston, VA - North Dakota and Montana have an estimated 3.0 to 4.3 billion barrels of undiscovered, technically recoverable oil in an area known as the Bakken Formation.
A U.S. Geological Survey assessment, released April 10, shows a 25-fold increase in the amount of oil that can be recovered compared to the agency's 1995 estimate of 151 million barrels of oil.
Technically recoverable oil resources are those producible using currently available technology and industry practices. USGS is the only provider of publicly available estimates of undiscovered technically recoverable oil and gas resources.
New geologic models applied to the Bakken Formation, advances in drilling and production technologies, and recent oil discoveries have resulted in these substantially larger technically recoverable oil volumes. About 105 million barrels of oil were produced from the Bakken Formation by the end of 2007.
The USGS Bakken study was undertaken as part of a nationwide project assessing domestic petroleum basins using standardized methodology and protocol as required by the Energy Policy and Conservation Act of 2000.
The Bakken Formation estimate 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. A "continuous" oil accumulation means that the oil resource is dispersed throughout a geologic
formation rather than existing as discrete, localized occurrences. The next largest "continuous" oil accumulation in the U.S. is in the Austin Chalk of Texas and Louisiana, with an undiscovered estimate of 1.0 billions of barrels of technically recoverable oil.
"It is clear that the Bakken formation contains a significant amount of oil - the question is how much of that oil is recoverable using today's technology?" said Senator Byron Dorgan, of North Dakota. "To get an answer to this important question, I requested that the U.S. Geological Survey complete this study, which will provide an up-to-date estimate on the amount of technically recoverable oil resources in the Bakken Shale formation."
The USGS estimate of 3.0 to 4.3 billion barrels of technically recoverable oil has a mean value of 3.65 billion barrels. Scientists conducted detailed studies in stratigraphy and structural geology and the modeling of petroleum geochemistry. They also combined their findings with historical exploration and production analyses to determine the undiscovered, technically recoverable oil estimates.
USGS worked with the North Dakota Geological Survey, a number of petroleum industry companies and independents, universities and other experts to develop a geological understanding of the Bakken Formation. These groups provided critical information and feedback on geological and engineering concepts important to building the geologic and production models used in the assessment.
Five continuous assessment units (AU) were identified and assessed in the Bakken Formation of North Dakota and Montana - the Elm Coulee-Billings Nose AU, the Central Basin-Poplar Dome AU, the Nesson-Little Knife Structural AU, the Eastern Expulsion Threshold AU, and the Northwest Expulsion Threshold AU.
At the time of the assessment, a limited number of wells have produced oil from three of the assessments units in Central Basin-Poplar Dome, Eastern Expulsion Threshold, and Northwest Expulsion Threshold.
The Elm Coulee oil field in Montana, discovered in 2000, has produced about 65 million barrels of the 105 million barrels of oil recovered from the Bakken Formation.

An action thriller by Jock Miller
Fossil fuel has an ageless affinity with dinosaurs. To create oil, dinosaurs died.
The perfect energy storm is sweeping over the United States: Japan’s Fukushima nuclear plant meltdown has paralyzed nuclear expansion globally, BP’s Gulf of Mexico oil spill has stalled deep water drilling, Arab oil countries are in turmoil causing doubt about access to future oil, the intensity of hurricanes hitting the Gulf’s oil rigs and refineries has intensified due to global warming, and the nation’s Strategic Oil Supply is riding on empty.As the energy storm intensifies, the nation’s access to Arab oil, once supplying over sixty percent of our fossil fuel, is being threatened causing people to panic for lack of gas at the pumps, stranding cars across the country and inciting riots.
The U.S. Military is forced to cut back air, land, and sea operations sucking up 58% of every barrel of oil to protect the nation; U.S. commercial airlines are forced to limit flights for lack of jet fuel; and businesses are challenged to power up their factories, and offices as the U.S. Department of Energy desperately tries to provide a balance of electric power from the network of aged power plants and transmission lines that power up the nation.
The United States must find new sources of domestic fossil fuel urgently or face an energy crisis that will plunge the nation into a deep depression worse than 1929.The energy storm is very real and happening this very moment. But, at the last moment of desperation, the United States discovers the world’s largest fossil fuel deposit found in a remote inaccessible mountain range within Alaska’s Noatak National Preserve surrounding six and a half million acres.
Preventing access to the oil is a colony of living fossil dinosaurs that will protect its territory to the death.Nobody gets out alive; nobody can identify the predator--until Dr. Kimberly Fulton, Curator of Paleontology at New York’s Museum of Natural History, is flown into the inaccessible area by Scott Chandler, the Marine veteran helicopter pilot who’s the Park’s Manager of Wildlife. All hell breaks loose when Fulton’s teenage son and his girlfriend vanish into the Park.
Will the nation’s military be paralyzed for lack of mobility fuel, and will people across America run out of gas and be stranded, or will the U.S. Military succeed in penetrating this remote mountain range in northwestern Alaska to restore fossil fuel supplies in time to save the nation from the worst energy driven catastrophe in recorded history?
