  • Prediction and subtraction of multiple diffractions
    Patent number: 10877172
    Abstract: Prediction and subtraction of multiple diffractions may include transforming previously acquired seismic data from a time-space domain to a transformed domain using a dictionary of compressive basis functions and separating, within the transformed previously acquired seismic data, a first portion and a second portion of the transformed previously acquired seismic data. Prediction and subtraction of multiple diffractions may also include predicting a plurality of multiple diffractions based on the separated first and second portions and adaptively subtracting the predicted multiple diffractions from the previously acquired seismic data. Prediction and subtraction of multiple diffractions may also include inverse transforming a particular seismic data set from the transformed domain to the time-space domain.
    Type: Grant
    Filed: April 25, 2019
    Date of Patent: December 29, 2020
    Assignee: PGS Geophysical AS
    Inventors: Robertus Franciscus Hegge, Paolo Terenghi, Andreas Klaedtke, Amr Ahmed Mahmoud Ibrahim
