List of oil fields of Montana

There are at least 45 named oil fields in Montana according to the U.S. Geological Survey, Board of Geographic Names. The USGS defines oil field as: "Area where petroleum is or was removed from the Earth."^[1]

An oil field is a region with an abundance of oil wells extracting petroleum (crude oil) from below ground. Because the oil reservoirs typically extend over a large area, possibly several hundred kilometres across, full exploitation entails multiple wells scattered across the area. In addition, there may be exploratory wells probing the edges, pipelines to transport the oil elsewhere, and support facilities.

The Schlumberger Oilfield Glossary defines oil field as: "An accumulation, pool or group of pools of oil in the subsurface. An oil field consists of a reservoir in a shape that will trap hydrocarbons and that is covered by an impermeable or sealing rock. Typically, industry professionals use the term with an implied assumption of economic size."^[2]
