Abstract

The experience of studying Artinskian sediments in a number of oil and gas fields in the Timan-Pechora Province showed that the solution of the problem of reservoir delineation, petrophysical properties evaluation and saturation character determination is an extremely difficult task. Building petrophysical models of reservoirs presents some difficulties due to low porosity and permeability of the rock matrix, multi-component composition and significant lithophysical heterogeneity of the rocks. Using a standard set of laboratory core analysis and well logs does not allow to reliably determine the mineralogical composition and total porosity of the rocks studied, which ultimately leads to an incorrect evaluation of secondary porosity and, as a consequence, types of reservoir rocks. Identification of permeable intervals in the Artinskian section without the use of modern set of well logs is almost impossible.
