FLOW SENSING APPARATUS AND METHODS FOR USE IN OIL AND GAS WELLS

摘要

The present invention is directed to methods for assessing flow-induced electrostatic energy in an oil and/or gas well wherein electric current or electrostatic potential or both are measured to produce data correlating to at least one flow characteristic of a tubular segment in the well. In some embodiments, electric current and electrostatic potential are produced separately for a plurality of segments, and measured. The system further may adjust at least one flow characteristic of a segment of the well to increase hydrocarbon production from the well.
