Relationship Between Reservoir and Electrical Parameters of Different Types of Carbonate Reservoirs.

In identifying reservoirs in a section, evaluating their saturation, and determining quantitatively their capacitive and filtration properties, it is necessary to know the character of the relation between the porosity parameter (P//p) and saturation porosity (K//p) which is determined to a considerable degree, by the type of reservoir. Taking the example of Upper Devonian carbonate deposits of Pripet and Dnieper-Donets depressions, the character of these relations for rocks of the cavernous-porous-fissured and porous-fissured types is considered. Practical recommendations for application of these relations are given.
