Latest Patents

One of Shah's latest patents is titled "Method for non-hyperbolic moveout analysis of seismic data." This method addresses the challenge of moveout-correcting Common Depth Point (CDP) gathers of seismic data by considering non-hyperbolic moveout at large offsets. The technique involves dividing the entire range of offsets into smaller segments, fitting curves to the reflection time versus offset data, and ensuring continuity at range boundaries. The curves can be hyperbolic or quartic, as available in commercial seismic data processing packages. The additional computation time required due to the absence of a single velocity function can be mitigated through interpolation techniques. This method is particularly useful for Amplitude Versus Offset (AVO) analysis.

Another significant patent by Shah is the "Method for deriving reservoir lithology and fluid content from pre-stack seismic reflection data." This innovative approach utilizes inversion of pre-stack seismic reflection data to derive subsurface lithology and fluid content at a target location. By comparing the results with a calibration location that has known subsurface characteristics, the method effectively determines the subsurface properties at the target site. The inversion process is preferably a viscoelastic inversion, which accounts for friction effects on seismic wave propagation.
