Absolute Permeability

Chapter 3 addressed porosity or, basically, the storage capacity of reservoir rock. However, merely having a large enough porosity of reservoir rock is not sufficient because the petroleum reservoir fluids contained in the pore spaces of reservoir rock have to flow so that they can be produced or brought to the surface from the reservoir. This particular property of a reservoir rock, denoted by k, is called permeability, which is conceptually illustrated in Figure 4.1. Permeability of a petroleum reservoir rock is one of the most influential parameters in determining the production capabilities of a hydrocarbon accumulation.
