...-specific petrophysical interpretations. Laboratory measurements provide key benchmarks for Monte Carlo modeling for validating liquid-saturated rock as well as gas-saturated rock models. This paper presents a very-low-porosity gas saturation evaluation example for two limestone formations in Oklahoma...

... predicted by the FSF-Fp method. Fig. 3 shows comparisons of MCNP and FSF-Fp methods in limestone formations. For the purpose of petrophysical interpretation, porosity differences in panel (c) across gas-saturated formations are calculated with the Gaymard-Poupon approximation (Gaymard and Poupon, 1968), i.e...

..., the ratio VP/Vs would be appropriate. Example 2 Our second example is from a thick shale section overlying a limestone formation. The limestone wavetrains (Figure 4a) show a clear S wave arrival while no S-wave is visible in the shale (Figure 4b). A binary plot of the shale data is shown in Figure 5. Again...

... spreading taken into account. For S wave attenuation the best method seems to be the analysis of the guided waves spectral amplitudes at two or more frequencies and then solve for the S wave attenuation using the partition coefficients. log analysis attenuation well logging Limestone Formation...
