Abstract
A method comprises obtaining or providing a treatment fluid comprising a viscosifier polymer; an aqueous carrier fluid comprising high total dissolved solids; and a polymer composition comprising at least one of polyvinyl alcohol and polylactic acid. In some embodiments, the treatment fluid has a viscosity at 140C and at a shear rate of about 0.1 s−1 to about 1 s−1 of about 1,500 cP to about 10,000 cP. The method includes placing the treatment fluid in a subterranean formation.
