WebLithology and porosity affect ∆t. Dense, consolidated formations characterized by compaction at depth generally result in a faster (shorter) twhile fluid-filled porosity ∆ results in a slower (longer) ∆t. Measurements are also … 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)
