The formation density log measures the bulk density of the formation. Its main use is to derive a value for the total porosity of the formation. It s also useful in the detection of gas-bearing …

Density logging is a well logging tool that can provide a continuous record of a formation's bulk density along the length of a borehole. In geology, bulk density is a function of the density of …

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: …

The density log measures electron density by detecting gamma rays that undergo Compton scattering. The intensity of scattered gamma rays is proportional to electron density. Electron …

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 …

Apr 24, 2013 · The density log measures electron density to derive porosity. The sonic log measures sound travel time to relate porosity using the Wyllie time-average equation. The …

Feb 27, 2025 · Gamma-gamma density (GGD) borehole logging is an active-nuclear method that is used to determine the bulk-formation densities of borehole-intersected formations. The GGD …

The density log, originally developed to aid in surface gravity data interpretation, has evolved as an independent log analysis device which provides another indirect means to measure porosity.

Density Logs. Learn density log basics for uncompensated, compensated, litho-density, and 90' Offset tools, bad hole effects, porosity scales, examples.

The formation density log measures the bulk density of the formation. Its main use is to derive a value for the total porosity of the formation. It is also useful in the detection of gas-bearing …
