Subsurface engineer

From Wikipedia, the free encyclopedia

Subsurface engineers (also known as completion engineers) are a subset within Petroleum Engineering. The typical job duties of a Subsurface Engineer include managing the interface between the reservoir and the well, including perforations, sand control, artificial lift, downhole flow control, and downhole monitoring equipment. The job of a Subsurface Engineer is effectively to select equipment that will best suit the subsurface environment in order to best produce the hydrocarbon reserves. Once the hardware has been selected, a Subsurface Engineer will monitor and adjust the equipment to ensure the well produces under ideal circumstances.
