Genetic Characteristics of Oils from the Orenburg and Saratov Deposits Based on the Results of Biomarker Studies

Abstract

SUMMARYBy results of researches the similarity of biomarker parameters of Saratov and Orenburg oils by origin and geological age is revealed. For most of the genetic parameters, the oil of the Orenburg field is of type A1, of marine origin, generated under reducing conditions; Oil is characterized by an elevated metal content. Petroleum of Saratov deposits is generated under sub-regenerative conditions in coastal-marine horizons; In them there are practically no metal-containing compounds.
