... in the matrix porosity is large compared with storage capacity in the fractures (Figure 1A). This is generally equivalent to a reservoir of type 3 in Nelson s classification (2001). For this case, it can be seen in the lower part of Figure 1A that a small percentage of the total porosity is made out...

... and cross plots. Once the electrofacies are determined for an area, cross plots can be used to determine lithology and volumetric lithological percentages. Log data should be corrected for possible gas and correct shale porosity effects which could lead to erroneous results from the cross plots...

... and recovery of hydrocarbons because it affects porosity, permeability, capillary pressure, particularly micro-inter-crystalline-framework and micro-fracture structures. As a result of this complexity, a Ruska Gas Permeameter was used at different pressures to measure the rock properties such as porosity...

... in underlying parameters such as porosity, permeability, structure, fault system, aquifer support, heterogeneous limit, etc. Thus, a detailed geological understanding of reservoirs will have a significant effect on history matching results. This paper describes the integration of mathematical models (SIMPLEX...

... to minimize SOR and maximize the COPrate. Numerical reservoir models of porosity, permeability, fluid saturation and facies that are required for flow simulation are generated using geostatistical techniques. One application of geostatistics is to characterize a potential SAGD reservoir and quantify...

.... This stochastic modelling is constrained by both horizontal and vertical wells. The geological model is defined at a very fine scale in order to preserve the description of heterogeneities near the well bores. Then, it is populated with lithofacies and initial petrophysical properties (porosity and permeability...

... body, porosity and permeability distribution. Then, the reservoir engineer can combine this geological model and dynamic data to construct a numerical simulation for whole field. The simulation will test the accurate level of geological model and reflect the performance of field in past times. Accurate...

The alteration of porosity and the impairment of permeability due to asphaltene deposition are also investigated. The case study reveals that the static surface deposition may...
