Paper: Net Oil Meters A Means Of Improved Productivity And Precision

A net oil meter has been developed that provides accurate measurement of the water and oil fractions and production rates of oil/water emulsions. The net oil meter incorporates integral mass flow rate, density and temperature measurements in a single package, coupled to a powerful microprocessor based transmitter. This transmitter is designed for easy installation in the oil field and on off-shore platforms. The net oil meter provides both improved productivity and precision. The equipment simplifies net oil measurement with more results, and includes automatic well testing. Calculations are obtained for the following: % water cut emulsion flow rate water flow rate oil flow rate total oil production total water production test time total emulsion emulsion density temperature The net oil meter operates on the basis of the Coriolis principle. The basic flowmeter and theory of operation is discussed below.
