Estimating Permeability of Vuggy-arrd-Fractured Carbonates by Modeling Mud-Filtrate-Invasion Effects on Resistivity Logs

摘要

A method was developed to diagnose and estimate secondary porosity and absolute permeability of vuggy-and-fractured carbonate formations by use of numerical simulation of mud-filtrate-invasion process. The method was used to interpret data acquired in a carbonate reservoir in the Barinas-Apure basin in southwestern Venezuela.
