The Bakken Formation: A basic explanation

This is a post by Piccolo, a petroleum engineer working in the petroleum industry.
The Bakken formation in North Dakota and Montana has generated a lot of buzz in the past year. Reserve numbers in the billions of barrels, even tens or hundreds of billions show up in press reports and blogs. Now the USGS has weighed in with a comprehensive assessment of the resource. So just how much will this oil accumulation help the world’s largest importer of oil? Is it time to relax or is this just another small blip in the long-term decline of domestic production? We’ll examine these questions and others below the fold, using data from the IHS database.

Overview of the Bakken

The Bakken is one of many hydrocarbon producing formations in the Williston Basin, a sedimentary basin covering parts of three states and two provinces. The total layer of sediments in the basin can be up to 15,000 ft thick, and within that, the Bakken itself reaches a maximum thickness of about 150 ft., but is thinner in most areas. The depth to the top of the Bakken can vary from a few thousand feet in Canada to more than 10,000 feet in the deeper areas in North Dakota. In terms of geologic age, it was deposited during the upper Devonian and Lower Mississippian periods about 360 million years ago. The entire stratigraphic column for the Williston Basin is shown below. Figure 2 indicates 15 primary producing formations in the basin, including the Bakken.

And what’s really “mindblowing” is that the lead in statement inre: Cruz Construction was taken word for word from an article dating from 2010. The Bakken oil boom has been a fact in western North Dakota for more than a decade, and has propelled ND to become one of the major oil producing states in the country.
