High water cut well measurements using heuristic salinity determination |
摘要 |
Methods and systems for determining the amount of water in a high water cut crude petroleum flow stream exiting from a hydrocarbon well. Electrical property measurements such as permittivity measurements are collected with a microwave analyzer system as high water cut oil exits from a well. Collection is continued until the span of the measurements of at least one property reaches at least a characteristic pre-determined value. A heuristic salinity of the water phase of the crude oil can then be determined based on the span statistics and reference equations and/or reference data. The flow-weighted average water content of the oil can then be determined using the heuristic salinity to correct for salinity variation as the output of the well changes over time.
