    Abstract

    The paper presents data on water content separated into free, physically and chemically bound types for a collection of core samples from the Bazhenov formation. The rock samples came from 3 wells of Nizhnevartovsk arch, Western Siberia, Russian Federation. Each rock sample was a part of whole core with the maximum preserved natural water content. A suite of modern laboratory techniques includes evaporation method, derivatographic, and hygrometric studies. The results show that the content of chemically bound water (06.4 wt.%) exceeds that of free (01.87 wt.%) and physically bound (01.0 wt.%). For the first time, we present the water content of mono-, poly-, and capillary condensation water obtained from the interpretation of adsorption isotherm. These data made it possible to draw a meaningful conclusion on mixed wettability of Bazhenov formation rocks.
