Integration of borehole image log enhances conventional electrofacies analysis in dual porosity carbonate reservoirs

Electrofacies based on conventional logs are found as strongly<br>correlated to core lithofacies, thin section microfacies, and<br>petrophysical measurements (φ/k and MICP) as long as the<br>carbonate pore system remains simple. Once dual porosity is<br>present, it is found that neural network using conventional<br>logs can not distinguish 2 rock types having the same range of<br>porosity but different porosity-permeability relation.
