Subsequently, facies and seismic properties are used for the three-dimensional distribution of petrophysical properties such as: rock type, porosity, clay volume...

... permeability models have been questionable in carbonates due to inherent heterogeneity and complex pore systems. The main objective of this paper is to resolve the porosity-permeability relationships and evaluate existing models for predicting permeability in different carbonate rock types. Over 1000 core...

... For the cored-based rock type the main reference was the Integrated Reservoir Characterization Study (IRCS), which is a reference study of the field that had defined texture, depositional environment and diagenesis. Abstract Reservoir Rock Typing and saturation modeling need a two-sided...

... Abstract Permeability and rock typing are two of the main outputs generated from the petrophysical domain and are particularly contributors to the highest degree of uncertainty during the history matching process in reservoir modeling, with the subsequent high impact in field development...

Nine plugs were selected to represent the different rock types and wettability conditions encountered in the well. A digital rock analysis (DRA) program was established...

... of selected plugs for core analysis programs. In carbonates, it is likely to have large permeability variations for one porosity value. Such permeability variations could be attributed to textural changes that may be defined and confirmed at the micro-scale using thin-section photomicrographs. Rock Typing...

The relationship between those...

.... Heterogeneities at smaller length scales must be upscaled into larger scale volumes to better predict reservoir performance. The objective in this study is to define carbonate rock types at multiple scales and then upscale those rock types and associated properties to the whole core level. Representative core...
