Stochastic Pore Fluid Modulus Inversion from Seismic and Rock Physics Data, a Case Study

C029 STOCHASTIC PORE FLUID MODULUS INVERSION FROM SEISMIC AND ROCK PHYSICS DATA A CASE STUDY Summary 1 This study involves a stochastic inversion from seismic data and well control to the fluid modulus and its probability within target layers of a hydrocarbon bearing field. The probabilistic inversion method based on Gassmann’s equation as described by White and Castagna (2002) is applied. The method deduces information about the type of fluid encountered in a particular rock by comparing its seismic response to that obtained when the rock is saturated with a fluid of known modulus. To perform this operation a synthetic
