Abstract

Summary

Recently unconventional reservoirs attract more and more attention in prospecting geophysics. Unconventional reservoirs often exhibit anisotropic physical properties due to specific features of their microstructure and texture. In the work a theoretical modeling of effective elastic properties of such a reservoir - fractured carbonate rock of low porosity - is considered. Commonly fractures in the reservoirs are sub-vertical which leads to HTI symmetry of the rock. Elastic constants of the carbonate reservoirs are calculated with the help of different approaches of the effective media theory: generalized singular approximation, Hudson’s model and Eshelby-Cheng model. The purpose of this work is estimation and analysis of small-anisotropy Thomsen’s parameters of fractured carbonate reservoir, examination of applicability of the parameters to predict elastic wave velocities in different directions and comparison of the results provided by different theoretical approaches.
