HYDRAULIC FRACTURING SYSTEM AND METHOD (EMBODIMENTS) Russian patent published in 2025 - IPC E21B43/26 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to oil and gas industry. In particular, a method of hydraulic fracturing is disclosed, which includes dehydration of a mixture for hydraulic fracturing of a formation at a centralized facility, wherein dehydration includes removal of at least a portion of water from the mixture for hydraulic fracturing; use of a low-shear addition system at a centralized facility to add a friction-reducing additive to the mixture for hydraulic fracturing to obtain a mixture for hydraulic fracturing with reduced friction, wherein the low shear addition system comprises at least one ejector or at least one screw; transportation of the mixture for hydraulic fracturing with reduced friction from the centralized facility to at least one hydraulic fracturing site through at least one pipeline and injection of the mixture for hydraulic fracturing with reduced friction into the reservoir for intensification of at least one well at said at least one hydraulic fracturing site.

EFFECT: higher efficiency of hydraulic fracturing.
