Abstract:
1. A method for estimating at least one elastic-wave-related property of a porous material from a sample thereof, comprising: making a three dimensional tomographic image of the sample of the material; segmenting the image into pixels each representing pore space or rock grain; determining bulk modulus and shear modulus of the porous material from the segmented image at a frequency corresponding to mobile fluid; determining bulk modulus and shear modulus of the porous material from the segmented image at a frequency corresponding to immobile fluid; determining the at least one elastic-wave-related property from the mobile fluid and immobile fluid moduli, wherein the at least one elastic-wave-related property comprises maximum inverse quality factor for shear elastic waves or maximum inverse quality factor for compressional elastic waves or both; and at least one of storing and displaying the at least one elastic-wave-related property.
