Abstract
Formation permeability and its variations are very important parameters in estimating the recovery potential of a reservoir. Conventional calculations of formation permeability from wireline logs are based on theoretical models of porous rock and resistivity and porosity measurements (e.g. the Carman-Kozeny relati.onship). We present a more direct measurement of formation permeability from Stoneley wave data in full waveform acoustic using a new and robust algorithm.
