Abstract

Permeability is the indispensable parameter in oil and gas reservoir studies. In fact of researching and operating on oil and gas fields worldwide, there are many types of permeability. Each permeability type has a specific characteristic according to the study purpose. In this article, the specific characteristics of some typical permeability as gas permeability; water permeability, effective permeability; relative permeability … will be analyzed, especially concern to the role of each permeability type in oil reservoir study to assisting researchers has an overview to orient their study.
