ALEXANDRIA, Va., June 19 -- United States Patent no. 12,332,396, issued on June 17, was assigned to Halliburton Energy Services Inc. (Houston).

"Machine learning guided subsurface formation microseismic imaging" was invented by Benjamin Simon Schaeffer (Denver).

According to the abstract* released by the U.S. Patent & Trademark Office: "Some implementations relate to a computer-implemented method for creating digital acoustic sensing (DAS) related training data for a learning machine. The method may include moving a first optimal microseismic event location to a first perturbed microseismic event location in each of a plurality of first images. The method also may include modifying first shear waves and first compressional waves in each o...
