Summary:
For more origin criteria oilfield White Tiger analyzed the material composition of oil and organic matter surrounding rocks, including - the analysis of patterns of relative distribution of saturated hydrocarbons-biomarkers at the molecular level, as well as their group composition. The data obtained allow us to confirm at a qualitatively new level the conclusion about the organic nature of oil in the crystalline basement of the Vietnamese shelf. Lying in the base of hydrocarbon deposit White Tiger by its characteristics do not differ from oil in the sedimentary sequences of Oligocene-Miocene cheholnogo complex, and those, in turn, complementary to the organic matter contained in sediments. These data suggest quite confidently that the accumulation of hydrocarbons in the foundation Kyulongskogo pool are in the secondary occurrence, and that the source of their formation is a sedimentary organic matter of productive systems of the Oligocene age.
