Comparison of influence on the formation by secondary and tertiary methods for the production of hydrocarbon compounds from oil source rocks with high oil-generating potential

Abstract

The work presents the comparison results of the quantitative and qualitative composition of hydrocarbon compounds that can be obtained as a result of secondary and tertiary methods of influence on organic-rich rocks (on the example of the Bazhenov Formation rocks) with a high oil-generating potential. It is shown that as a result of extraction of bitumoids presented in open pores, realisation the generation potential and the production of synthetic oil, it is possible to produce hydrocarbon compounds, the amount of which reaches 35 kg and 20 kg per 1 m3 of rock, respectively. Products possess high maturity and are identical in composition to the oil extracted from these rocks by standard technology of development. It was found that with the development of appropriate technologies of subsequent influence on the formation by secondary and tertiary methods, oil production can be significantly increased in the future.
