PREDICTION OF THE LITHOLOGICAL COMPOSITION OF THE BAZHENOV FORMATION BASED ON INTEGRATED INTERPRETATION OF GEOLOGICAL AND GEOPHYSICAL MATERIALS (ON THE EXAMPLE OF CROSS-SECTIONS IN THE NORTHERN REGIONS OF KHANTY-MANSI AUTONOMOUS AREA)

Abstract

The article presents a methodology developed by the authors for calculating the lithological composition of the Bazhenov Formation in Western Siberia. It is based on the identified relationships between the mineral-component composition and physical properties of rocks. The physical meaning of the identified connections has been substantiated. Satisfactory convergence of the calculated values and core data is shown. Possibilities of using the developed technique in wells not characterized by core material and limitations for its application are described.
