ABSTRACT:
High viscosity well treating fluids having low friction pressure loss when pumped through tubular goods and methods of treating wells using such treating fluids are provided. The treating fluids basically comprise an aqueous fluid, a graft copolymer of hydroxyalkylcellulose and vinyl phosphonic acid, a salt containing a divalent cation and a basic compound for crosslinking the graft copolymer and causing the resulting crosslinked aqueous gel to undergo syneresis.
