Patent ID: 8498177

Claim:
A method for determining a location of a geological layer in a subterranean formation from seismic data, comprising: receiving the seismic data representing an interaction of the geological layer with propagation of a seismic wave; identifying, from the seismic data, a source wavelet representing a portion of the seismic wave impinging on a boundary of the geological layer; providing a geological layer template of the geological layer comprising primary and secondary reflection interfaces associated with reflectivity based on material properties of the geological layer; generating, by a computer processor using a mathematical convolution operation, a plurality of modeled slope parameters by applying the source wavelet to the geological layer template; generating a wavelet response table comprising the plurality of modeled slope parameters to model a seismic wave interference caused by the primary and secondary reflection interfaces; calculating a slope associated with an extremum of the seismic data; and determining, by at least comparing the slope associated with the extremum of the seismic data to the plurality of modeled slope parameters, the location of the geological layer in the subterranean formation using the wavelet response table.
