The pore spaces in rocks which form oil and gas reservoirs are always completely saturated with fluids. There are never any void spaces within the pores ...

Learning Objectives After completing this topic “Permeability Measurement“, you will be able to: Discuss the laboratory methods used to measure permeability. Describe permeameter measurements of formation permeability. Summarize the factors affecting a rock’s measured permeability values. State the accuracy of laboratory permeability measurements. Introduction to Formation Permeability and its Measurement …

Porosity is the volumetric void space within rocks, being that space not occupied by solid rock material. Porosity is thus a measure of a reservoir's storage ....
