Apr 5, 2022 · The density–neutron log is a combination log that simultaneously records neutron and density porosity. In some zones, porosities recorded on the logs differ for three reasons: …

As an industry standard the Neutron Porosity log is recorded in Limestone Porosity Units and displayed in either V/V units, P.U. (Porosity Units), % (percentage) or decimal units (dec.). The …

Combination Neutron-Density Log The combination of the neutron and density measurements is the most widely used. It displays neutron porosity (NPHI) and density porosity (DPHI) in tracks …

Researchers performed a log-based assessment of key geological parameters influencing production.2 Digitized logs were deep enough to reach the base of the Haynesville, including …

The overlay of the density-neutron porosity log overlay was introduced by logging companies as a means to evaluate volumetric porosity free from lithology effects. However, the overlay …

May 26, 1998 · A new well logging method for evaluating gas-bearing reservoirs has been developed. The method combines total porosity from the CMR Combinable Magnetic …
