The use of a multiphase meter for wellhead production has never been a realistic option for producers in the Western Canadian Sedimentary Basin. This has been due to the high cost of multiphase meters and their questionable performance in Canadian oil and gas fields. A UK-based company has recently developed a new multiphase measurement system and has tested the system on a conventional oil well in Alberta. The technology used by the company is based on known and proven metering instruments and combines them with sophisticated multiphase and gas void fraction calculations to give results for oil, water and gas volumes. This paper will describe the testing of the multiphase measurement system, and it will also show the results of the comparison data from the multiphase measurement system to the dedicated wellhead separator meters. The paper will show that the results are comparable and within regulatory volumetric uncertainty specifications.
