| Abstract | Different carbonate pore classes show large variation in petrophysics properties as well as in single- and two-phase flow properties. A few attempts have been recorded in the past to find correlation between petro-physics parameters and pore classes. Results showed that this approach gives improved correlations between porosity and permeability. However, the extension of the concept to integration of basic petrophysics properties and multiphase flow has not yet been extensively investigated. This paper represents an attempt to apply the pore class concept to multiphase flow properties. In order to address this issue, carbonate samples have been grouped into different pore classes, like intercrystalline, interparticle, moldic, and chalk material, with its subset of grouping for macro-, meso- or micro-porosity and further split into homogeneous or more heterogeneous / patchy material, all based on thin section analysis and porositypermeability cross plots. The cores representing different carbonate pore classes have earlier been used to measure both petrophysical parameters such as porosity, permeability, electrical properties, derived tortuosities, dispersion, and capillary pressure and pore size distribution. These results formed the background for the current multiphase flow analysis by water flooding. The results have shown that grouping carbonates with respect to different pore classes improves correlations between some of the petrophysics properties and oil recovery efficiency by waterflooding |
