Abstract

​

With depletion of major gas reservoirs in West Siberia, survey of the Upper Cretaceous (the over-Cenomanian) sediments known for gas shows, inflows, and gas discoveries has assumed an increasing importance. In the sediments dated to the Coniacian, the Santonian, and the Campanian that overlie the Cenomanian formations, uncharacteristic for West Siberia silica clay rocks occur, including gaize sediments in the Upper Santonian and calcareous shales dated to the Maastrichtian age. Taking into account the fact that depending on the present-day conditions the same-genesis formations can act either as reservoirs or as caprocks, a non-conventional comprehensive approach should be applied to study the lithological-mineralogical structure of the Upper Cretaceous formations. The paper presents new results of studies obtained in 2019, including an integrated characteristic of dispersed organic matter in the Upper Cretaceous rocks and the objective estimate of its oil-generating potential, as well as the economic assessment.
