A detailed seismic modeling work has been carried out to identify the most appropriate Previous HitelasticNext Hit rock modulus (or Previous HitmoduliNext Hit) that are sensitive to reservoir pore fluid types. This work is being applied to both oil and gas bearing clastic and carbonate reservoirs from different fields within Saudi Arabia. The sensitivity of each modulus to the reservoir pore fluid saturation was also analyzed. Among those Previous HitmoduliNext Hit are Vp/Vs ratio, lambda-Rho, and bulk modulus. Modeling results ranked investigated Previous HitelasticNext Hit Previous HitmoduliTop with regards to their effectiveness as “fluid indicators”. These results also set rules of thumb as to which modulus is suitable for a given set of reservoir conditions.
