Latest Patents
James M Johnston holds a patent for a "Method and apparatus for evaluating flow characteristics of fluid behind." This invention provides a method and system for well logging that offers insights into the characteristics of fluid flow behind pipes. The system utilizes an acoustic listening device positioned within a pipe, close to suspected fluid flow. It detects acoustic energy resulting from the fluid flow and separates it into two frequency groups: one comprising relatively low-frequency acoustic energy and the other comprising relatively higher frequency. The relative distribution of this acoustic energy serves as an indicator of the nature of the fluid flow behind the pipe.
