Abstract
A new algorithm is suggested for the joint calculation of three key parameters of reservoir rocks: permeability, electroacoustic constant, and velocity of second bulk compressional wave (slow wave). The algorithm is advantageous in the use of Stoneley waves which are most stable in acoustoelectric log waveform data.
