Abstract:
1. A method of measuring radial fluid flow in a casing having an interior wall, the method comprising: inserting a tool body into the casing, wherein the tool body comprises an arm with an electromagnetic sensing device attached to a distal end thereof, and wherein an electrical line is coupled to the tool body; transmitting electrical power to the tool body via the electrical line; axially traversing the casing with the tool body; azimuthally rotating the arm to sweep the electromagnetic sensing device around the casing interior wall; sensing for a radial flow of conductive fluid through the casing interior wall with the electromagnetic sensing device; receiving and recording information regarding the radial flow of conductive fluid, from the electromagnetic sensing device via the electrical line; determining an azimuthal orientation of the radial flow of conductive fluid in the casing; and generating a logging graph of a casing depth versus an amount of the radial flow of conductive fluid, from the information.
