Acoustic Flowmeter Field Test Results

Abstract

Summary The newly developed borehole acoustic flowmeter provides data to locate depth precisely and to quantify gas production from individual gas entries, even when they are spaced closely together, for low-flow-rate gas-producing zones in a typical Devonian shale well in the Appalachian basin. Data from a field test conducted in Aug. 1987 are presented, along with the measurement theory involved. A comparison to a conventional spinner flowmeter on the same well is also presented.
