Lithology density

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. SpectroLith* lithology processing of Webgamma rays have passed. This gives information about the density of the formation in the same way as for the conventional formation density tool. The count rate of the soft gamma rays in the lower energy shaded window in Fig. 14.2 is a measure of the density of the material (how many electrons there are available to take part in photo-absorption)

WebThe Lithology Density Tool (LDT) is used to measure the bulk density of the formation, which is then related to formation porosity. The tool also determines the Pe of the formation, allowing for lithology identification, and contains a motorized caliper that is used for borehole diameter information. 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.
