Petroleum Extraction Well (Oil Well)
Petroleum Extraction Well (Oil Well): A petroleum extraction well, or an oil well, is a deep borehole or shaft sunk into the Earth for the exploration of oil or gas. Additionally, injection wells are often drilled to inject fluids or gas for stimulating oil recovery, re-pressurizing or pressure maintenance of oil or gas, or for disposing of waste fluids from an oil or a gas field. Eagle Ford Shale, located in South Texas, is a significant oil well area, and it is one of the most actively drilled targets for oil, due to its rich supply of hydrocarbon resources.
