Modeling of Bazhenov formation of Western Siberia as an unconventional hydrocarbon source

Authors: S.V. Malysheva, V.E. Vasilyev, D.K. Komissarov (Gazpromneft NTC LLC, RF, Saint-Petersburg), M. Saint-Germes, J.-M. Laigle (Beicip Franlab, France, Rueil-Malmaison), M. V. Pereslegin (Salym Petroleum Development LLC, RF, Moscow), S.F. Khafizov (Gazprom Neft JSC; RF, Saint-Petersburg, Gubkin Russian State University of Oil and Gas, RF, Moscow)

Key words: Bazhenov formation, basin modeling, unconventional resources, organic porosity.

The case study of Bazhenov formation of Western Siberia shows methodological approach for unconventional hydrocarbon potential assessment with basin modeling tools. The study results include maturity schemes of Bazhenov formation in the study area, volumes of generated hydrocarbons and Bazhenov formation self-sourced potential estimates. A lot of attention paid for creating present day TOC maps and initial TOC restoration as well as calculation of “organic” porosity which is formed when kerogen transforms into hydrocarbons.
