However when samples are water saturated the bulk modulus of the rock is frequency dependent Modeling with Gassmann s equations predicts the measured saturated rock bulk modulus for all fluids for frequencies below 20 Hz but underpredicts the water saturated basalt bulk modulus for frequencies greater than 20 Hz The most likely reason is that the pore fluid pressures are unrelaxed Instead
