Sensitivity of P-P and P-SV AVO Reflectivity to Fluid Properties in Porous Media – Extension of P-P Results and P-SV Investigation

P06 SENSITIVITY OF P-P AND P-SV AVO REFLECTIVITY TO FLUID PROPERTIES IN POROUS MEDIA: EXTENSION OF P-P RESULTS AND P-SV INVESTIGATION Abstract 1 The objectives of this investigation is two-fold: First to extend the examination of the dynamic effects of variations in relevant fluid properties (permeability and fluid viscosity) on the total P-P wave reflectivity variations with angle of incidence. The reflecting boundaries considered are limited to the interface between two different fluids within a common reservoir sand extending a previous preliminary study but including a realistic description of the fluid models. For fluid-fluid reservoir contacts the AVO effects were
