Assessment of Rock Mechanics Properties Starting From Geophysics Logs with the Garcia-Garcia: A General Model For Calculating Total Compressibility and Formation

摘要

This paper uses the effective media theory to estimate the heterogeneous distribution, the bulk and formation compressibility in the reservoir, in function of rock elastic properties, such as, the volumetric moduli (K) and shear (μ) vs. depth, by means of field available data, such as geophysical logs (density and sonic).rnResults from four (4) naturally fractured carbonated reservoir are shown and from one sand reservoir counting on log information for validation.
