Storage, processing and transportation of oil and gas to refineries and end users are all part of midstream oil and gas activities. Water cut measurement is needed at a number of points within this process. It is typical that oil and gas will change hands, with midstream companies taking responsibility for transportation to refineries for processing, for example. Custody transfer measurement is required, as well as measurement at onloading for transportation, with water cut measurement being a required and key control point. The Roxar Watercut meter provides the measurement needed with reliability and accuracy in the forefront.
