Web1 dec. 2024 · However, although gamma ray is a better lithology indicator than velocity ratio, in a case of ambiguity, velocity ratio is necessary to validate the result obtained from gamma ray analysis. Both Mu-rho and density are lithology discriminators but density has advantage over mu-rho when it comes to fluid prediction in reservoir. Web18 jan. 2024 · Measured density is the sum of the rock system density and the pore fluid system density. Density values can therefore be used directly to identify lithology only when the porosity is insignificant. In porous rocks, density must be interpreted in combination with neutron or other porosity logs. Lithological Responses (Nonporous rocks)

WebA common practice in log interpretation is to cross-plot various porosity log readings in order to determine formation lithology and compute porosity accurately. Crossplots of Sonic versus Density logs are widely used in the interpretation of shaly sands. For carbonates, Density versus Neutron cross-plots are commonly employed. Webbined with the measured bulk density to derive an accurate total porosity. In a similar way, the elemental concentra-tions of silicon, calcium, and iron are used to correct the neutron log for rock matrix effects, thereby yielding neutron porosity that is significantly closer to total porosity.
