Systems and method for down-hole phase monitoring

Abstract:

A measurement tool configured to be run through a bore of a hydrocarbon well. The measurement tool includes a dielectric core, a controller disposed at a first end of the dielectric core, a first wire helically disposed about the dielectric core and extending from the controller to a first location a first distance from the controller, and a second wire helically disposed about the dielectric core and extending from the controller to a second location a second distance from the controller. The controller provides first and second input signals to the first and second wires, and receives first and second reflected signals from the first and second wires.
