METHOD OF PRODUCING MIXTURE FOR HYDRAULIC FRACTURING AT CENTRALIZED FACILITY (EMBODIMENTS) Russian patent published in 2025 - IPC E21B43/26 B01F23/50 B01F25/312 

FIELD: mining.

SUBSTANCE: group of inventions relates to a method of producing a mixture for hydraulic fracturing at a centralized facility for delivery to one or more hydraulic fracturing sites. Method involves receiving water at a centralized facility, receiving sand from one or more sand pits at the centralized facility, receiving one or more chemicals at the centralized facility. Process equipment of a centralized facility is used for treatment of water, sand and one or more chemicals to obtain a mixture for hydraulic fracturing. Process equipment includes dilution manifold, dehydration equipment, mixing equipment, or a low shear addition system for adding a friction reducing additive to the fracturing mixture, or a combination thereof. Dilution reservoir is intended for dilution of concentrations of sand, one or more chemical substances or both in the formation hydraulic fracturing site. Dehydration equipment is designed to remove water from the mixture for hydraulic fracturing. Mixing equipment is designed to add water to the mixture for hydraulic fracturing. Mixture is transported for hydraulic fracturing from centralized facility to one or more hydraulic fracturing sites.

EFFECT: increased efficiency of mix transfer for hydraulic fracturing from centralized facility to one or more hydraulic fracturing sites.
