Definition of oil field in English English dictionary
An area under which are reserves of petroleum, especially one with productive oil wells
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
A productive oil or gas formation comprising one or more reservoirs, usually related to the same geological features
