Abstract
A method and composition for treating a subterranean formation penetrated by a wellbore including preparing an aqueous composition containing a source of boron, 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 composition, combining the composition with a mixture comprising a viscosifier and aqueous medium to form a treatment fluid, wherein the 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, and contacting the formation with the treatment fluid to treat the formation. The source of boron may be boric acid.
Claims8
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.
