Reasons for low-resistant oil formations, criteria of their selection and productivity evaluation
Kh.I. ShakarovThe paper reviews the issues of low-resistivity of oil-saturated formations and analyzes the studies carried out in this direction as well. The definition of specific electric resistance plays a significant role in the selection of reservoir-beds and the evaluation of their productivity. The analysis of the complex of downhole geophysical surveys conducted in Azerbaijan territory justifies that in some cases the geological section consists of the layering of formations with anisotropic properties varying by their resistance and permeability. Neglecting such aspects in the data processing and interpretation leads to the distortions. In the definition of oil saturation of soil units consisting of sand-clay interlayers’ alternation, it is practical to consider the anisotropic nature and comparisons “resistance correlations”.
