Abstract
A process for achieving enhanced levels of friction reduction in high salinity conditions, particularly suited to slick-water hydraulic fracturing and coiled tubing applications, uses low charge and preferably uncharged water soluble high molecular weight polymers. A fracturing fluid is injected into a conduit. The fracturing fluid is an aqueous solution comprising at least one water soluble (co)polymer comprising less than 10 mol % ionic monomer(s), and the aqueous solution comprises total dissolved salts concentration ranging from 100,000 mg/L to up to the salt concentration at which the aqueous solution becomes saturated in salts.
