A Discussion on the Shear-To Compressional-Mode (SP) – Theoretical, Practical and Economic

P023 A DISCUSSION ON THE SHEAR- TO COMPRESSIONAL-MODE (SP): THEORETICAL PRACTICAL AND ECONOMIC Abstract 1 While it is very common to acquire process and interpret compressional-mode (P) data that have been converted to the shear-mode (S) the reciprocal scenario S to P (SP) is very uncommon. We discuss some of the practical economic and theoretical issues associated with the SP mode. Since P-wave seismic is the standard within our industry SP will likely only be available when nine component data are being acquired. The two main advantages of SP over PS would be that we have a controlled source polarization
