ABSTRACT:
A method of determining the net volume of water and oil in a flow stream, including the steps of collecting the fluid in a vessel providing a quiescent zone, venting pressure from the vessel to permit at least a portion of dissolved gas to flush from the fluid, repressuring the fluid within the vessel to a superatmospheric pressure to force any remaining entrained gas bubbles back into solution, passing the fluid from the vessel while subjected to a superatmospheric pressure through a sonic apparatus having a sonic path disposed at an angle to the flow stream to measure the upstream and downstream speed of sound transmission of the fluid, calculating from the difference in the upstream and downstream speeds of sound transmission the volume of fluid flow and from the summation of the speeds of sound transmission the fluid composition, and from these calculations the net volume of oil and water flow.
