Development of system for semi-continuous monitoring of salinity in well streams to remove volume measurement errors and detect water breakthrough
SalinityScan will focus on developing a subsea sampling and analysis system capable of monitoring the salinity of the water fraction in the multiphase flow from oil and gas wells. Enabling sampling of the salinity will increase the accuracy in subsea flow measurements and consequently improve well management.
The SalinityScan sampling system will be integrated in the multiphase flow line, where it will sample the flow at user-defined intervals. The fluid will be separated into its single phases and the salinity of the water fraction will then be measured. The SalinityScan data will be used to update the flow meter calibration parameters, thereby removing the offset caused by the change in salinity. Additionally, by semi-continuously monitoring the salinity it becomes much easier to detect water breakthroughs.
