Our research work delivered rock typing model that honors static properties all together, through changing classification to resolve the gaps of traditional methods. The goal of reservoir characterization and rock typing is to enable building geological and simulation models, that best honor properties. To achieve target, we build framework that focused on analyzing effects of each rock property on another, adding to the model's most critical boundaries. This technique resolved the gap of pore and pore-throat network through Multiple Properties Intersection.

This Integrated Carbonate Rock Typing technique starts with capturing the heterogeneity of carbonate rock by creating a matrix of core permeability, capillary pressure (end point, threshold pressure, and Plateau), pore-throat size distribution and porosity. Then intersecting matrix properties to compose weighted links between properties and to identify unique groups. Resulted classes are new carbonate rock type classes that entered to feedback analysis node to explore and confirm linked physics to tune classes’ thresholds and ensure no overlap between groups. Finally, for using this technique in non-cored wells, we built an analogue with logging data through innovative permeability, capillary pressure, and saturation function technique. The novel function names are, CROPC-1, CROPC-2, (CROPC: Conjunction of Rock Properties Convergence) and RocMate C-Function (RocMate: Rock Type Matrix), while the novel permeability estimation technique is called MPTE, (MPTE: Multi Property Threshold Environment).
