STAVANGER, Norway -- Schlumberger is using ONS to launch its well site multiphase fluid sampling and analysis service called PhaseSampler.

The product operates at line pressure and temperature, using an optical phase detector to distinguish between oil, gas, and water. It has a full operating range from heavy oil to gas-condensate.

"Representative fluid and flow information, available at every stage of a well's life, helps operators reduce uncertainty during exploration, monitor treatment effects in development, and clarify production allocation," says Vlamir Bastos, Schlumberger's PhaseSampler product champion.

A Russian operator used the PhaseSampler service to conduct a comprehensive well testing campaign in a gas condensate field in Western Siberia. By using this service, the operator was able to accurately measure the reservoir fluid properties and rates to optimize production, according to Schlumberger.

It also enabled a better understanding of the transient nature of reservoir fluid composition during a multirate test and allocation of multiphase flow in commingled situations, Schlumberger says.
