ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,392,923, issued on Aug. 19, was assigned to Halliburton Energy Services Inc. (Houston).
"Resistivity logging in sliding mode" was invented by Hsu-Hsiang Wu (Sugar Land, Texas), Yi Jing Fan (Singapore) and Jin Ma (Houston).
According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for smoothing a resistivity log are disclosed. An azimuthal resistivity tool measures azimuthal impedances at multiple azimuthal angles around a wellbore axis at each depth. It is determined whether the drill string was in a drilling mode or a sliding mode at the depth. If the drill string was in the drilling mode, a co-axial component and a lateral component are determi...
