Method for Estimating Permeability of Fractured Rock Formations from Induced Slow Fluid Pressure Waves

Case ID:
C13729
Disclosure Date:
7/9/2015
The present invention relates generally to geophysical exploration. The invention relates to a method for estimating the permeability of fractured rock formations from the analysis of a slow fluid pressure wave, which is generated by pressurization of a borehole. Wave propagation in the rock is recorded with TFITM although other imaging or pressure monitoring techniques could be used. Poroelastic theory is then employed to estimate the permeability from the measured wave speed.
