P301 Heavy Oil Reservoir Characterization Using Vp/Vs Ratios from Multicomponent Data C.C. Dumitrescu* (Sensor Geophysical Ltd) & L. Lines (CHORUS University of Calgary) SUMMARY Vp/Vs is a very good lithology discriminator especially for heavy oil projects. We provide two VpVs ratio volumes based on (i) simultaneous inversion on prestack PP data and (ii) joint inversion of PP and PS poststack data. The new results are compared with the previous results based on the traveltime measurements on the PP and PS components (Lines et al. 2005). The area for this project is a heavy oil field (oil sands of the Devonian-Mississippian
