ALEXANDRIA, Va., June 4 -- United States Patent no. 12,320,939, issued on June 3, was assigned to Landmark Graphics Corp. (Houston).

"Frequency-dependent machine learning model in seismic interpretation" was invented by Fan Jiang (Sugarland, Texas), Alejandro Jaramillo (Edinburgh, Great Britain) and Steven Roy Angelovich (Livermore, Colo.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Frequency-dependent machine-learning (ML) models can be used to interpret seismic data. A system can apply spectral decomposition to pre-processed training data to generate frequency-dependent training data of two or more frequencies. The system can train two or more ML models using the frequency-dependent training data. Subseq...
