Abstract
Allochthonous bitumens of the Abalak Formation and oils of the Shaim petroliferous area (PA) were studied in detail at the molecular level. They are similar in some geochemical parameters to autochthonous bitumens from mudstones and bazhenovites of the Bazhenov Horizon of the West Siberian megabasin.
The heterochronous reservoir beds of the Upper-Middle Jurassic deposits and weathering crusts in the Shaim PA form fluid-dynamic complexes related to each other and to the source of naphthides and thus combined into a single system.
