ABSTRACT
Gas-water flows can be quantitatively profiled using data from a diverting flowmeter combined with a focused density tool. Characterizations of the flowmeter and the density tool are described based on flow loop evaluations of the instruments in gas-water flows in a pipe at a 45° deviation. An interpretive method is presented; it uses the characterizations to interpret instrument responses, yielding quantitative values of the gas-water total flow rate and water cut. A flow loop simulation is described for a gas-water production stream that flows in a pipe deviated at 45° and has five known gas and/or water additions. The simulation results demonstrate the accuracy with which the logs and interpretations can quantitatively determine the known additions.
