Abstract
Summary
The Bazhenov formation rocks research by standard petrophysical methods gives distorted or incorrect result, so it requires some innovative approaches. This work presents the cation exchange capacity (CAC), oxidation-reduction (ORP) and diffusion-adsorption (DAP) potentials determination. As well as wettability by adsorption method. The main methodogical feautures of experiments with Bazhenov rocks were identified. It was found high values of ORP and hydrophobicity coefficient in couple with low values of CAC in oil-saturated intervals. The DAP value depends on clay content and carbonate inclusions presence
