Porosity from bulk density
The density log measures the electron density of a formation. The logging device is a contact tool that emits gamma rays from a source. Emitted gamma rays collide with formation electrons and scatter. A detector, located a fixed distance from the tool source, counts the number of returning gamma rays. The number … See more Formation bulk density is a function of matrix density, porosity, and fluids contained in the pore space. Formation bulk density measured by the log must be corrected for borehole … See more 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: 1. The matrix density used by the logging … See more The neutron logmainly measures hydrogen concentration in a formation. The logging device is a noncontact tool that emits neutrons from a … See more Lithology, porosity, fluid type, and tool type affect neutron log response. When interpreting neutron logs, use the specific log for the specific tool, i.e., the charts in logging chart books that are specific to the sidewall neutron log … See more WebSep 9, 2015 · The electron density for most minerals and fluids encountered in oil and gas wells is directly proportional to their bulk density, P bulk. The bulk density measured by the tool, P log, results from the combined effects of the fluid (porosity) and the rock (matrix) and is used to compute density porosity.
