Simultaneous Inversion of PP and PS Seismic Data – A Case History from Western Canada

A10 SIMULTANEOUS INVERSION OF PP AND PS SEISMIC DATA – A CASE HISTORY FROM WESTERN CANADA Summary: 1 K. HIRSCHE D. HAMPSON J. PERON AND B. RUSSELL Hampson Russell Software 510 715 – 5 Ave SW Calgary Alta. Canada T2P-2X6 We have recently developed a new method for simultaneously inverting P-wave and converted wave (PS) seismic volumes. This new inversion approach accounts for the physical relationship that exists between P-wave and S-wave velocities and it provides a significant improvement over independent inversions of the two datasets; particularly for Vp/Vs ratio estimates. We applied this new inversion technique to a 3D
