Abstract
Official abstract text for this publication.
Pairs of acoustic transducers positioned at different radial distances in a conduit are used to measure travel times of acoustic signals in opposite directions and inclined to the direction of a fluid flow in the borehole. These contrapropagation measurements are used to estimate fluid velocity and volumetric flow rates of the fluid components in the conduit.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus configured to estimate a volumetric flow rate of each fluid in a mixture of a plurality of fluids in a conduit, the plurality of fluids having a stratified flow, the apparatus comprising: a plurality of contrapropagation detectors arranged in the stratified flow at a plurality of radial distances from a center of the conduit; and a first support member configured to support a first subset of the plurality of contrapropagation detectors; the…
