Claim Text:
1. A method of treating a subterranean formation penetrated by a wellbore, the method comprising: preparing an aqueous crosslinker slurry composition comprising water and a solid source of boron as a crosslinker, whereby boron is present in the slurry in an amount of about 1.7% or greater, by weight, based upon a total weight of the crosslinker slurry composition; combining the crosslinker slurry composition with a mixture comprising a viscosifier and an aqueous medium to form a treatment fluid, wherein the crosslinker slurry composition is added to the mixture in an amount of about 0.5% or less, by volume, based upon a total volume of the treatment fluid; increasing a viscosity of the treatment fluid with the solid source of boron as the crosslinker; and, contacting the formation with the treatment fluid to treat the formation.
