The use of newer oilfield technologies, including hydraulic fracturing and horizontal drilling, has single-handedly made the Bakken one of the largest oil developments in the United States. It has transformed North Dakota, this once sleepy state, into a hub-bub of activity that has brought economic development to the region, employment opportunities, and improved the lives of many people.

The Bakken is a large formation that is not going anywhere soon. The United States Geological Survey (USGS) estimates that there are still 4.4 to 11.4 billion barrels of undiscovered, recoverable oil in the Bakken Formation. They also estimate that there is an additional 6.7 trillion cubic feet of natural gas as well.


The Bakken is primarily composed of shale rock that geologists believe were deposited in the late Devonian and early Mississippian age, or about 360 to 320 million years ago. There are three layers in the Bakken Formation rock: a top and a bottom shale layer with a siltstone and sandstone layer in the middle. The shale layers serve to trap the oil in the middle layer, so you can think of the shale layers as the slices of bread of a sandwich with your meat in the middle.

Northern Oilfield Services in Williston notes that this layer where the oil lives has a very low permeability and low porosity, which is why it lay untapped for so long. Underneath the Bakken shale layers is another layer of shale known as the Three Forks. Hydraulic fracturing and horizontal drilling are used to access the oil in this layer as well. Scientists believe that this layer holds over half the undiscovered and recoverable petroleum resources in the Bakken Formation.


Oil is believed by scientists to be the remains of long dead plants, tiny marine organisms, and animals, which is fascinating when you think about how everything on earth is recycled.

Scientists believe petroleum is formed when dead organic matter settles on the bottom of riverbeds and oceans. Northern Oilfield Services in Williston notes that these remains mix with mud and sand. As more and more dead matter and material lay on top, the heat and pressure turns the organic material into a dark and waxy material, which scientists call kerogen.

Kerogen eventually turns into carbon and hydrogen atoms in a liquefied state. Depending on the amount of liquid or gas that is trapped in the organic matter determines whether petroleum or natural gas will form. It is estimated that this process takes hundreds of thousands of years, which is why oil and gas are considered nonrenewable resources.
