Abstract

Relevance Development of shale-oil as a potential crude hydrocarbon source is the most pressing issue for production depression areas with well-developed infrastructure. This regards West Siberian petroleum province, where «shale oil» is associated with Bazhenov suite bituminous shale, indicating proven commercial productivity within several areas. The aim of the research is to estimate the role of planetary fracturing in Bazhenov suite bituminous shale deposits for enhancing shaleoil development efficiency and to identify auto-generation conditions of planetary fracturing based on Bazhenov suite sampling results. Research target: Jurassic-Cretaceous bituminous shale in Bazhenov suite, southeast West Siberian Plate. Research methodology is based on the following correlation: abstract theorem of planetary fracturing to both surveys of fractured Bazhenov suite deposits, sampling results from Glukhovsky well 2 and fundamental features of shale formation Bakken end Barnet development in North America. Results: The analysis performed, being based on published sources and core data, indicated a significant development of vertical rupture within Bazhenov suite formation section. The geological age correlation between the identified fracture systems and global rotation stress field traces within Eurasia territories was revealed. Identical oil inflow dynamics was determined on the basis of Bazhenov suite sampling data via both powder generator of pressure in Glukhovsky area and shale formation hydrofracturing in USA 42-24A well within Bakken formation (North America).
