Lithology density
Web28 jul. 2016 · Lithology and porosity affect ∆t. Dense, consolidated formations characterized by compaction at depth generally result in a faster (shorter) ∆t while fluid-filled porosity results in a slower (longer) ∆t. Measurements are also uniquely affected by formation and borehole conditions. WebThe Lithology Density Tool measures the bulk density of the formation, which is related …
