ABOUT OIL-BEARING FORMATION OF ROMASHKINSKOE OIL FIELD – EVIDENCE FROM BEREZOVSKAYA AREA

Abstract

This paper is devoted to the geochemical study of the oils of the South Tatar arch and their possible generation sources. The connection between the OM of the Domanik formation and oils and bitumen from the same age-old sediments was found. The relationship between bitumen from the basement rocks and the oils of the productive Devonian terrigenous strata was determined on the basis of their close component and biomarker composition. The generality of the reducing conditions for their sedimentation indicate the presence of a deep fluid component in the formation of the oil-bearing capacity of the sedimentary strata in the Beryozovskaya area of the Romashkinskoye oil field.
