Rational Rock Physics for Improved Velocity Prediction and Reservoir Properties Estimation for Granite Wash (Tight Sands) in Anadarko Basin, Texas
Figure 14
A composite log example from Granite Wash (Marmaton) section. Plots from left to right show logs of (a) , (b) Water saturation , (c) porosity, (d) density, (e) compressional velocity , and (f) Poisson ratio (PR). Fluid substitution is carried out for brine (blue) and gas (red) scenarios using dry rock data derived from logs.
