METHOD FOR INCREASING EFFICIENCY OF OIL AND GAS PRODUCTION AT IMPLEMENTATION OF MULTI-STAGE HYDRAULIC FRACTURING Russian patent published in 2019 - IPC E21B43/26 E21B34/14

Abstract RU 2702037 C1

FIELD: oil and gas industry.

SUBSTANCE: invention relates to production of hydrocarbons and can be used in development of oil and/or gas reservoirs with multi-stage hydraulic fracturing of the formation. After multi-stage hydraulic fracturing, intervalwise pressure increase and proppant injection using coupling and/or ports with built-in inflow control devices and filter element, as well as built-in devices for fluid inflow monitoring are performed.

EFFECT: technical result achieved during implementation of the developed method consists in possibility to control influx during production, which will allow to increase oil production efficiency, reducing or eliminating problems with water and gas breakthroughs to the well after MSHF, as well as preventing proppant release after MSHF, which will increase efficiency of multi-stage hydraulic fracturing of the formation and increase oil production.
