FRACTURE WATER TREATMENT METHOD AND SYSTEM Russian patent published in 2017 - IPC E21B43/34 B01D21/34 C02F1/00 

FIELD: hydraulic engineering.

SUBSTANCE: group of inventions relates to fracture water treatment methods, systems and multiphase separators. Method of treating fracture water from a hydrocarbon well, comprises separating solids, liquid hydrocarbons and gaseous hydrocarbons from fracture water, wherein a flow of water with suspended solid particles results; separating the flow of water into a plurality of flows of water; generating positive charge in each of the plurality the flows of water by treating each of the plurality of flows of water with electromagnetic flux, wherein a plurality of flows of positively-charged water results; Slowing the flow rate in the plurality of separate flows of water; comingling the plurality of flows of positively-charged water after said generating; comingling the flow of positively-charged water with proppant and its returning it in the hydrocarbon well. Majority of the suspended solids are less than about 100 microns. Slow flow rate is less than the flow rate of the flow of water with suspended solids.

EFFECT: technical is safety of hydraulic fracturing process.
