West Siberian Basin
The West Siberian
Basin accounts for over 65% of oil production and ~90% of gas
production in Russia, yet large parts of the basin are under
explored. This basin formed as a rift basin in the late
Permian-early Triassic between the East European and Siberian
cratons. The irregular nature of the basement resulted in
focused sediment deposition during syn-rift and early post-rift
phases. Many fundamental questions remain about aspects of the
basin evolution and of reservoir formation, distribution and
quality. Exposures of Mesozoic strata occur around the basin
allowing sedimentological and structural field investigations
and enabling sample collection for laboratory analysis.
