Multiphase Flowmeter and Sampling System Yield Real-Time Wellsite Results

A new well testing technology allows fluid collection for analysis, determination of fluid properties at line conditions and pinpointing of dry gas properties, all at the wellsite

Multiphase well testing is recognized as state-of-the-art technology for metering oil, gas and water streams without needing to first separate phases. It is particularly effective when measuring transient and volume flows for condensate and heavier oils when traditional meters are less effective. An-other benefit is easier deployment to harsh, isolated regions, such as the Siberian gas-condensate field discussed here.

A past challenge of multiphase well testing has been an in-ability to collect representative fluid samples for real-time com-positional analysis. However, a new, highly portable system has been developed that allows collection of such samples and then determines fluid volumetric properties at line conditions along with dry gas properties. Combining these properties can minimize uncertainties that often arise when key fluid parameters are not correctly entered in a multiphase flowmeter’s computation algorithm. Basic Pressure, Volume and Temperature (PVT) measurements can be made at the wellsite. This improves the multiphase flowmeter’s ability to compute flowrates.
