Abstract

Summary

The petrophysical characteristics determination of the Bazhenov formation rocks is very difficult. Previously used adsorption method to study the wettability, due to the large organic matter content in the mineral matrix, showed a high degree of hydrophilicity. There is proposed an alternative approach to determining the “wettability index” using the NMR method by direct spectra comparison of rock saturated with water and kerosene. This approach allows successfully solving the organic matter content problem and controlling the results obtained by the adsorption method correctness. As a result, the “wettability index” according to NMR of the Bazhenov formation varies from neutral (in the top and bottom) to hydrophobic wettability (in the middle of the section), which correlates well with the distribution of organic matter.
