A logging method for estimating permeability, velocity of second compressional wave, and electroacoustic constant in electrolyte-saturated porous formations

A new algorithm is suggested for 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.
