P-WAVE AND S-WAVE SEPARATION OF SEISMIC DATA IN THE PRESENCE OF STATICS AND IRREGULAR GEOMETRY

摘要

Methods and systems for separating P-S wave field data are described. Slowness values for the PP mode and the PS mode are estimated and are, typically, unequal based on aliased and/or irregularly sampled data. A calculation, in the space-time domain, based on a matrix of equations, generates separated P-wave and S-wave data. The separated P-wave data and S-wave data are output for further imaging.

1. A method, stored in a memory and executing on a processor, for separating P-wave data and S-wave data in acquired seismic data said method comprising:
estimating, in a space-time domain, a P-wave slowness value and an S-wave slowness value; separating the P-wave data and the S-wave data using the estimated P-wave slowness value and S-wave slowness value; and outputting the separated P-wave data and the separated S-wave data.
