rock porosity

Course, we lose some through the rock porosity, but we manage to keep ahead of that."

Their results offer a more sophisticated picture of rock porosity and a resolution of the discrepancy between permeability and melt velocity.

The neutron porosity log is predominantly sensitive to the quantity of hydrogen atoms in a particular formation, which generally corresponds to rock porosity.

Nuclear magnetic resonance analysis of these boreholes is used to measure rock porosity, estimate permeability from pore size distribution and identify pore fluids (water, oil and gas).

Any change in rock porosity caused by the dissolution or precipitation of minerals when fluid flows through sedimentary or fractured basement rocks affects the rocks' permeability, and hence how fast fluid flows through the rocks and what volume is transmitted.
