METHOD AND APPARATUS FOR DETERMINING THE WATER CONTENT OF AN OIL STREAM

摘要

At least the water content of an oil stream from a production oil well is determined by measuring the mass flow of the oil stream while the stream is under backpressure, diverting a known sample portion of the stream to a separator vessel, separating the sample into oil, gas and water fractions and measuring the relative flows of the fractions. The measured amounts are then used to calculate the oil, gas and water content of the main oil stream.
