| Summary: | Seismic rock physics is a connector between seismic data and the in situ condition
of reservoir. It cans modeless the fluid on the rock and its effect to seismic wave
properties. Fluids substitution is an important thing to be done in seismic rock
physics studies. Fluid substitution represents a part of seismic modeling and
qualification of various fluid substitutions scenarios which can not only give clue
to AVO response but also to seismic post data for direct hydrocarbon indicator or
DHI. Fluid substation involves Gassmann equation (approximation of low
frequency). Problem in fluid substitutions predicting seismic velocity of rock are
affect of fluid saturated, effect of pore of matrix. Gassmann equation will estimate
fluid effect to bulk modulus properties. Prediction of bulk modulus properties can
used to analyze DHI like spot bright amplitude and AVO |
