The geological diversity of oil deposits is the basis for the technological development of the industry

A deep study of the mechanism and processes of development of the bitumen and heavy oil deposits, as well as oil in tight and shale reservoirs, was conducted in the special test facilities in North America. These studies served as the basis for a technological leap for the transfer of these resources to the category of recoverable reserves. Based on the development of new technologies for horizontal drilling, multi-stage hydraulic fracturing, and the SAGD method in various modifications, commercially attractive results have been achieved, which allow stable development of fields with unconventional reserves at low oil prices. Marginal reserves in a deep crisis environment are the main reason for the write-off of reserves and their transition to large diversified companies.
