Heterogeneity quantification,fine-scale layering derived from image logs and cores

摘要

Most carbonate reservoirs offshore Abu Dhabi are characterized by complex textural heterogeneity that can be detected by high-resolution borehole image logs.This textural heterogeneity gives rise to extreme permeability variation that is the controlling factor in reservoir production.A study conducted by ZADCO and Schlumberger illustrates an approach to improve carbonate reservoir characterization of an offshore Abu Dhabi oil field,by quantifying fine-scale heterogeneity using borehole image logs and core measurements.
