WebPorosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to … Data: Porosity and density measurements.

Furthermore, microstructure observations of the sea urchin spine present a porous characteristic and gradually varying porosity from the center to the outer edge ( Fig ... WebThe porosity reflects "free" water in the sandstones, but bound water in the shales. The density log is a measure of apparent density of the rock and is computed from the absorption of gamma rays emitted from a tool radioactive source by the formation.

WebJun 24, 2015 · This is the source of "gas crossover" on neutron density-log displays (see Fig. 3). Moreover, the shallow-reading density log frequently is an invaded-zone measurement, completely masking the gas effect on it. Because the neutron porosity is deeper reading, it is often the only log that can be used for gas detection.
