What are the environmental considerations of drilling for oil?

Environmental issues include:

  • land surface disturbance
  • the amount of water initially required to hydraulically fracture (or “frack”) the well
  • disposal of the poor-quality water produced with the oil
  • air pollution
  • groundwater contamination
  • oil spills
  • disruption of wildlife corridors

In many cases, particularly on private land, it is the state government that regulates the extraction of oil and the remediation of sites after production is no longer economic.

What are the oil reserves in the Bakken Formation?

The USGS provides estimates of undiscovered, technically recoverable resources that have yet to be found (drilled), but if found, could be produced using currently available technology and industry practices. These estimates are based on knowledge about the geology of the area. In contrast, reserves are oil resources that are already discovered,...

How much oil and gas are actually in the Bakken Formation?

The USGS estimates that there may be 4.4 to 11.4 billion barrels of undiscovered, technically recoverable oil in the Bakken Formation (with a mean estimate of 7.4 billion barrels). These are estimates of oil that has yet to be found, but if found, could be produced using currently available technology and industry practices. Estimates are based on...

What are some of the difficulties of drilling in the Bakken Formation?

Traditional oil fields extract oil from rocks with relatively high porosity and permeability, so the oil flows out fairly easily. In contrast, the Bakken Formation is a relatively tight formation with low porosity and low permeability rock, from which oil flows with difficulty. To overcome this problem, wells in the Bakken Formation use a method...

What are "technically recoverable" oil and gas resources?

“Technically recoverable” means that the oil and/or gas can be produced using currently available technology and industry practices. This is regardless of any economic or accessibility considerations. For example, the technology required to produce oil from a location might exist, but it costs more than the oil is worth. The oil is still...

How much oil does the Bakken Formation produce and how does this compare to what the United States uses?

The USGS does not maintain statistics on oil production or oil consumption. Production information can be obtained from publicly available sources like the North Dakota Department of Mineral Resources , and/or the Montana Department of Natural Resources and Conservation . The U.S. Energy Information Administration provides information on oil...

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...

Vegetation Recovery on Abandoned Oil and Gas Well Sites is Variable on Colorado Plateau

Recovery of vegetation on plugged and abandoned oil and gas well sites on the Colorado Plateau is influenced by time, moisture, nonnative plants and the type of plant community that was originally in place before well sites were constructed, according to a recently published study by the U.S. Geological Survey.

Oil Spill Samples

On April 20, 2010, the Deepwater Horizon Drilling Platform exploded and sank, causing the largest oil spill yet recorded. Samples from the oil spill were collected by Louisiana USGS scientists Greg Swayze and Charlie Demas and sent for analysis in Menlo Park, CA. Each sample was placed in a glass jar detailing the date, time, and location it was discovered.
