Emerson launches Roxar Salinity Measurement System

May 10, 2017 - Emerson Automation Solutions launched the Roxar Salinity Measurement System for the sensitive, real-time measurement of saline water in gas production well streams at the Offshore Technology Conference (OTC) in Houston.

Through the system, operators can identify changes in the flow stream and the smallest amounts of saline water at high levels of sensitivity. This enables the operator to take immediate remedial action to prevent threats to production, such as scaling, hydrate formation and corrosion. The onset of formation water and its salinity, if not controlled, can lead to well shutdowns and cost producers millions in unplanned shutdown time.

The system, which is a key element of the Roxar Subsea Wetgas Meter and is based on microwave (MW) resonance technology, provides quantitative and qualitative real-time salinity measurements in many types of field conditions but, particularly, in the high gas volume fraction (GVF)/wet gas flows that characterize wet gas fields.

The Roxar Salinity Measurement System has been designed as part of the Roxar Subsea Wetgas Meter, which provides individual flow rates of gas, condensate/oil and water. The salinity system consists of a salinity sensor mounted flush with the wall of the meter. The MW resonance technology ensures a response to changes to conductivity of the flow stream - in seconds not minutes - and the ability to measure water conductivity down to ± 0.1 S/m and up to 99.99% GVF and sensitivity in the range of ± 0,004 S/m. Small pockets of formation water leaking into the flow can therefore be detected instantaneously rather than in hours and days.

Emerson conducted extensive testing of the system internally and at the Colorado Experience Engineering Station (CEESI) in the United States based on an operator’s specifications. In all cases, the system was found to have the high levels of accuracy and sensitivity required.
