Abstract
A method for quantifying permeability of a vuggy reservoir includes determining a permeability modeled with matrix porosity (K0) of the reservoir, determining a vug porosity (&PHgr;vug) of the reservoir, and quantifying permeability (K) of the reservoir as follows:K=aK0·bc&PHgr;wg,where a, b, and c are constants.
