Permeability (of A Reservoir Rock)
Permeability (of A Reservoir Rock) : The ability of a rock to transmit fluid through the pore spaces: A key influence in the rate of flow, movement and drainage of the fluid. There is no necessary relation between porosity and permeability. A rock may be highly porous and yet impermeable if there is no communication between pores. A highly porous sand is usually highly permeable. See: Effective Permeability. (ITOGP)
