Scale-dependence of rock physics models and transforms
Abstract/Contents
- Abstract
- The subsurface is a heterogeneous mixture of porous rocks volumes. Treating a rock volume that is intrinsically heterogeneous as a homogeneous body requires characterizing it with certain "effective" attributes. Numerous rock physics models and transforms implicitly treat rocks as homogeneous bodies as they require a single value for each of the rock's attributes as input. The question is if such rock physics models and transforms were established for rock samples at a given scale of measurement and treated as homogeneous bodies, will rock samples measured at coarser scale, yet once again treated as homogeneous bodies, still obey the model? This dissertation aims to find how to adapt/apply rock physics models and transforms that treat rocks as homogeneous bodies to a composite that is inherently heterogeneous. The key contributions of this dissertation are (1) estimations of effective elastic properties of heterogeneous bodies to be used in fluid substitution operations, (2) analysis of applicability of rock-physics models established at one scale of measurement (e.g., well-log scale) to coarse-scale measurements (e.g., seismic scale), (3) introduction of the notion of elastic mineral facies concept, (4) estimations of coarse-scale relations between the effective bulk modulus of the fluid to fluid saturation in a rock volume where two fluid phases are present, and (5) estimation and prediction of effective elastic properties of digital rock samples.
