The Western Siberian Basin is one of the largest in Russia and covers territories nine federal provinces; the basin’s area is close to 3.5 million square kilometers. If the basin alone was a nation, it would be 7 th largest in the world, after Australia and before India. The majority of oil deposits here are at depths of 2 to 3 thousand meters. The local oil is famous for its low sulfur and paraffin content, high gasoline volatiles ratio.
“The main goal was to assess the characteristics of source rocks, including the origin, redox depositional conditions and the degree of thermal maturity of these types of hydrocarbons to facilitate their development. Samples were analyzed using traditional geochemical and physical methods,” says co-author, Junior Research Associate Ameen A. Al-Muntaser .
The research team found that the studied oils are paraffinic. The result is confirmed by a high value of the fraction of saturated hydrocarbons in excess of seventy percent by volume. The samples are also low in sulfur.
