P-P and P-S inversion of 3-C seismic data: Blackfoot, Alberta

Robert J. Ferguson

ABSTRACT

P-P and P-S inversion was applied to the vertical and radial components of the Blackfoot 3-C survey, to yield P velocity, S velocity and Vp/Vs. This work was done as part of an ongoing inversion project which will compare the Velocity estimates from different frequency ranges. The results of the work to this point indicate that for the 10 Hz data, both the P-P and P-S inversion methods provide good velocity values. The resulting Vp/Vs estimates showed a Vp/Vs decrease over the zone of interest. Pre-inversion processing flows were developed for both the P-P and P-S data.
