Latest Patents

One of Jyoti's latest patents focuses on noise mitigation for time-lapse surveys. This innovation discloses techniques for reducing noise when computing time-lapse differences between two or more geophysical surveys performed over the same region. In some computer-implemented embodiments, a time-lapse difference is determined between first and second data representing the first and second surveys, respectively. Based on geometry information corresponding to the second survey, first estimated data is generated representing how the first data would have looked if the second survey geometry had been used during the first survey. A noise model is generated based on differences between the first data and the first estimated data. The time-lapse difference is then adjusted using the noise model, thereby reducing noise in the time-lapse difference caused by differences between the geometries of the first and second surveys.

Another significant patent by Jyoti involves correcting time shifts. This method includes performing Normal MoveOut (NMO) correction on a first Common Depth Point (CDP) gather, based on a reference velocity of sound in water. The NMO correction creates first NMO data with a plurality of traces. Jyoti selects a first estimated velocity that makes travel time represented in the traces substantially the same. She calculates a zero-offset time shift that represents a difference in travel time as between the reference velocity and the first estimated velocity at a zero-offset trace. The process continues with performing NMO correction on the first CDP gather based on a final estimated velocity to create second NMO data. Finally, she adds the zero-offset time shift to each trace of the second NMO data and performs reverse NMO correction on the second NMO data to create corrected data.
