FIELD: oil and gas industry.
SUBSTANCE: extraction method of oil and/or gas from an underground formation involves the following: the first well in the formation; a transfer mechanism to the first well of a mixed composition improving oil recovery; the second well in the formation; a mechanism for extraction from the second well of oil and/or gas; with that, the first well and the second well is an internal part of the system; a set of barrier wells outside the first well and the second well; and a mechanism for transfer to the barrier wells of a barrier agent for displacement of the mixed composition improving oil recovery and/or oil or gas in the formation to the second well for extraction of the product from the above second well.
EFFECT: improving efficiency of solutions based on use of a mixing displacement technology.
