“…Samples in each class seem indistinguishable due to similar geological depositions and diagenetic alterations . Many methods have addressed rock typing, for example: - Based on mechanical properties, mineralogy, and organic geochemistry
- The use of permeability, porosity, and irreducible water saturation data either empirically ,− or with a hydraulic flow unit (HFU) approach; ,,
- Involvement of capillary pressure data and J -function − and combined with radius;
- Consideration of thin section descriptions and interpretations such as rock fabrics, depositional facies, and rock textures; ,
- Geostatistics and machine learning implementation such as clustering, , ANN, self-organizing map, , and fuzzy logic;
- Grouping based on the dimensionless form of absolute permeability, relative permeability, porosity, and phase viscosity, the so-called true effective mobility TEM function; ,
- The use of resistivity data and porosity to yield in electrical flow unit;
- Further development of analytical models, such as the pore geometry and structure (PGS) method. −
