Quick Reference
Absolute porosity is the total of all void spaces present within a rock, but not all these spaces will be interconnected and thus able to contain and transmit fluids. The effective porosity is thus defined as the proportion of the rock which consists of interconnected pores. Porosity is expressed as a percentage of the bulk volume of the rock. See also choquette and pray classification; fenestral porosity; fracture porosity; moldic porosity; and oomoldic porosity.
