Abstract

According to geochemical hydrocarbon indicators (the concentration ratios for the composition of the C4-C9 hydrocarbons, n-alkanes, C10-C13 adamantanes and acyclic isoprenanes, steranes, terpanes and aromatic compounds) and carbon isotope composition, the condensates of the Maloyamalskoe deposit correspond to the terrigenous genotype. The hydrocarbon maturity indexes (the isomer ratios of steranes and terpanes, maturity indices calculated by aromatic composition) indicate the origination of the hydrocarbon fluids in the conditions of the “oil window”. The adamantan and its alkyl-substituted identified in the studied condensates.
