Well Performance
Although there are several techniques for measuring net oil and water cut from a producing oil well, each method has its particular requirements and limitations. Various technologies have been used in this application and their characteristics are briefly discussed in various sources.
Net oil is the volume of oil, corrected to a reference temperature that is contained within a gross volume of produced fluid. In order to determine net oil, it is necessary to determine the water cut of the produced fluid. Water cut is the volume fraction of production fluid that is produced water.
Oil well performance was first measured by flowing into tanks. Although simple in concept, tank testing does not lend itself to accurate water cut measurement, temperature compensation for volume, or compensation for evaporation and backpressure. Test times can also be unreasonably long for low producers.
To overcome these limitations, vessel type separators were introduced. These test separators are connected to a manifold where all of the wells in a nearby area are tied in. The wells are tested one at a time, while the other wells in the manifold flow to the production separator.
