pdf Characterization of Bazhenov Formation productive interval: a case study of West-Kvenzer area, southeastern Western Siberia
The article discusses the concept of Bazhenov reservoir rocks exemplified by a oil productive interval of the Bazhenov Formation cross-section in the West-Kvenzer area, southeastern Western Siberia. Characteristics of the analyzed interval are derived from the interpretation of the results obtained by the geophysics, lithology, rock physics and organic geochemistry integrating methods. It has been shown that the studied oil saturated interval is represented by kerogen-siliceous and siliceous mixtites. The studied rocks are found to be identical in terms of the lithological composition, organic matter geochemistry, geophysical and petrophysical characteristics. Most of the mobile (allochthonous) bitumoids (chloroform extractable bitumens) generated by the Bazhenov Formation within the West-Kvenzer area are concentrated in open pore space, rather than being fracture-filling type.

Keywords: Bazhenov reservoir, Bazhenov Formation, organic matter, mobile bitumoid, West-Kvenzer area, southeastern Western Siberia.
