A geographical area under which an oil reservoir lies.
A geographic area under which an oil reservoir lies.
The surface area overlying an oil reservoir or reservoirs. Commonly, the term includes not only the surface area but may include the reservoir, the wells, and production equipment as well.
An oil field is a region with an abundance of oil wells extracting petroleum (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.
