Abstract
A method includes steps of: providing a treatment fluid including an aqueous base fluid, a gelling agent, and a multifunctional boronic crosslinker, and introducing the treatment fluid into a subterranean formation. The multifunctional boronic crosslinker includes a dendritic polymer including a water-soluble monomer and a boronic acid group, and the ratio of the water-soluble monomer to the boronic acid group is in the range from about 1:210 to about 1:800.
