Abstract

See full text

Aqueous suspensions are presented that are stable against settling without additional mixing in which the suspensions comprise a water soluble polymer that is anionic or non-ionic comprising a blend of water with at least about 32 weight percent chloride salt with a counter ion A+a with 2≤a, from about 1 wt % to about 10 wt % particulate polyethylene glycol having an average molecular weight from about 1600 g/mol to about 50,000 g/mol, and from about 10 wt % to about 50 wt % of the water soluble polymer that is not a poly ether. The suspension has chlorides in a sufficient amount to inhibit hydration of the suspended water soluble polymer and the particulate polyethylene glycol. The aqueous suspension can be formed by adding a powder of polyethylene glycol to a high salt solution and then adding the high molecular weight polymer. The aqueous suspensions can be useful as friction reducing agents in flowing liquids, such as for hydraulic fracture.
