Abstract

The article presents a comparative analysis of the results obtained using the Dean-Stark method and the evaporation method for rock samples of the Bazhenov formation of the Nizhnevartovsk arch (West Siberia, Russia). The research results show that the Dean-Stark method is not effective for determining the residual water content of low-permeable (tight) Bazhenov reservoir rocks with low pore water content. The residual water content in the samples obtained by the evaporation method ranges from 0.11 to 1.63 wt.% and varies unevenly with the depth. The amount of free water according to the evaporation method falls in the range of 0–0.99 wt.%.
