Bakken Formation |
Throughout history, most of the great oil and gas fields have been discovered. This one will be unlocked through innovation.
The Bakken Formation is one of the largest contiguous deposits of oil and natural gas in the
United States. It is an interbedded sequence of black shale, siltstone and sandstone that underlies
large areas of northwestern North Dakota, northeastern Montana, southern Saskatchewan and
southwestern Manitoba. The Bakken was deposited within the Williston Basin and is Late
Devonian to Early Mississippian in age.
The Bakken Formation consists of a lower shale member, a middle sandstone member and an upper shale member.
The shales are organic-rich and of marine origin. They are rich source rocks for oil and natural
gas. All three members of the Bakken Formation have been known to yield oil and natural gas.
Just a few years ago the Bakken was considered a marginal to submarginal resource because the oil and
gas are locked in a rock formation with a low permeability. However, advances
in drilling and recovery technology such as horizontal drilling and hydrofracturing have transformed it into a
viable resource. The formation is expected to provide a boost to our energy supply and economy. Much of the oil in the Bakken requires additional advances in technology or higher oil prices for profitable recovery.
The USGS Assessment for the Bakken Formation estimated mean undiscovered volumes of 3.65 billion barrels of oil, 1.85
trillion cubic feet of associated / dissolved natural gas, and 148 million barrels of natural gas liquids
in the United States portion of the Bakken Formation.
These resources are contained within both conventional and unconventional reservoirs. The Bakken Formation
in Canada contains additional resources and has been called one of the largest oil fields in Canada.
In early 2008 only a few wells had been drilled into the Bakken and its viability as a resource was uncertain.
However, through late-2008 several successful wells have been drilled with the new technologies and
an explosion of interest now surrounds the deposit.
Throughout history, most great oil and gas fields have been discovered. This one will be unlocked through innovation.

Bakken Formation Map |
| The Bakken Formation underlies large areas of northwestern North
Dakota, northeastern Montana, southern Saskatchewan and southwestern Manitoba. |
|
| The Bakken Formation became a viable resource because of advances in drilling and recovery methods.
Horizontal drilling enables wells to have a much longer "pay zone" than a traditional vertical well. Hydrofracturing
produces porosity in the rock unit that facilitates movement of oil or gas to the well. Together, these methods allow a single well
to drain a much larger volume of rock and more efficiently recover the oil and gas resource. |
