FIELD: oil and gas industry.
SUBSTANCE: in order to create limit depression on formation determined by Young 's modulus and porosity factor of reservoir bed, liquid is extracted from well. But oil involved in deposit development is in pores under original pressure. Under pressure differential between formation pressure and bottom-hole pressure equal to formation ultimate compression strength, liquid destroys interpore partitions and moves towards well. Additional micro cracks are produced, factors of porosity and permeability of formation are increased, well service life is prolonged.
EFFECT: increasing oil production of production wells and injection well water-intake capacity.
