Subsurface engineer

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 (or Completions 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.
