Wellhead Production Measurement

A test separator is used for the separation of oil, water and gas to determine production volumes. If a two-phase separator is used, the combined liquids must be measured and reported for plant proration and royalty reporting. Water cut measurement can be challenging because the liquids being measured are comprised of an oil/water mix with the oil typically at the hydrocarbon vapour pressure. Measurement of live fluid is a complex process control problem. Production fluids change characteristics over the life of a well. Spartan’s NOC (Net Oil Computer) reports alarms and warnings when conditions affecting measurement occur. This information can help determine what is happening to the well at a given time and ensure accurate measurement. The Net Oil Computer can be integrated into a plant SCADA host system for remote operation and data analysis.


Production fluids must be accurately measured for plant proration, and government reporting compliance. In many cases, remote test separator control is a requirement because wells produce a mixture of oil, water and gas. 


Spartan’s Wellhead NOC (Net Oil Computer)  provide accurate measurement for volume and water cut in compliance with regulatory guidelines. Our NOC solution is expandable, providing customers with multiple options for their automation requirements. Specification time was reduced, saving our customer $25,000 in billable hours.
