abstract |
1482247 Lubricants &c CALGON CORP 16 July 1975 [26 July 1974] 29878/75 Heading C5F [Also in Division E1] Frictional losses in the flow of aqueous liquids through a conduit (in particular of a fracturing fluid in the hydraulic fracturing of subterranean formations) is reduced by maintaining in the fluid at least 1 p.p.m. of poly- (dimethylaminomethylacrylamide). The fluid to which the polymer is added may be fresh water, brine or an acidic fracturing fluid. |
