THE DEVELOPMENT OF A NEW WATER/OIL MIXTURE FACILITY FOR TESTING SAMPLING TECHNIQUES AND FLOW METERS

摘要

From a recent investigation by CEESI, it is clear that the independent data available on the performance of custody transfer metering systems to operate with high water content, 5-90%, is both scattered and sparse. As a result of the investigation, CEESI were commissioned to produce a water in oil test facility, aimed at carrying out experimental work on both the direct metering and sampling of high water cuts. It is designed to be able to change the oil viscosity, to look at the effect of viscosity variation on the performance of the measuring instruments. The paper describes the design of the flow facility, which has individually measured oil and water inputs, pipe sizes from 2" up to 8" capability, clear viewing sections in horizontal and vertical piping, a flexible working section for testing the instruments in different orientations, and sampling section to determine the distribution of mixing across the pipe cross sections.
