The method of determination of the kerogen and bitumoids content in the Artinskian sediments of an oil and gas field of the Orenburg region by well logging data

Abstract

The lithological and geochemical studies of the Artinskian carbonate sediments of one of the gas and oil fields in the southwest of the Orenburg region revealed a significant amount of indigenous organic matter in the productive intervals of the section. The study of thin sections established that the organic matter content in the examined rocks reaches 3.75 wt%, with the average value of this parameter being 1.05 wt%. The article is devoted to the development of methods for estimating the content of kerogen and bitumens in rocks according to well logging data.
