Abstract
A method of servicing a wellbore within a subterranean formation comprising providing a first wellbore tubular positioned within a second wellbore tubular creating a tubular flowpath and an annular flowpath, wherein the tubular flowpath and the annular flowpath converge in a mixing zone within the wellbore, placing an annular fluid through the annular flowpath, placing a tubular fluid through the tubular flowpath, and contacting the annular fluid and the tubular fluid in the mixing zone to form a composite fluid, wherein the composite fluid comprises a base fluid component, a proppant component, a crosslinkable polymer component, a crosslinking agent component, and an optional buffering agent component and wherein the components of the composite fluid are apportioned between the annular fluid and the tubular fluid such that reaction of the components to form the composite fluid is inhibited until the components of the composite fluid mix within the mixing zone.
