Abstract
A well treatment fluid uses ingredients that include an aqueous base, a non-associative, ionic, synthetic polymer, and optionally, at least one metal crosslinker. The polymer contains a backbone and a functional group that hinders hydrolysis of the backbone. The functional group is distributed at intervals on the backbone. A well treatment method includes forming a well treatment fluid by combining ingredients including a non-associative, ionic, synthetic polymer and a first aqueous base. The first fluid exhibits a first viscosity greater than a viscosity of the first aqueous base. The method includes treating a well during a stage using the first fluid exhibiting the first viscosity. A second well treatment fluid is formed by combining ingredients including the polymer, a second aqueous base, and at least one crosslinker and by crosslinking the synthetic polymer. The method includes treating the well during another stage using the second fluid exhibiting the second viscosity.
