Technical Note


Absolute permeability is a key reservoir parameter and is particularly vital for reservoir management during the reservoir life cycle. The basic law of fluid flow in porous media is Darcy’s Law. The Darcy equation demonstrates that the velocity of a fluid in a porous medium is inversely proportional to the fluid viscosity and proportional to the pressure gradient (Ahmed and McKinney 2005):
$$Q= - \frac{{KA}}{\mu }\frac{{{\text{d}}P}}{{{\text{d}}L}},$$
