    Abstract: The present invention provides a method of reducing the viscosity of a viscosified treatment fluid comprising the steps of: providing a viscosified treatment fluid that comprises water, a crosslinked gelling agent, and a delinking composition capable of delinking at least a portion of the crosslinked gelling agent wherein the delinking composition comprises a delinking agent; and allowing the crosslinked gelling agent and the delinking composition to interact so as to delink at least a portion of the crosslinked gelling agent. The present invention also provides methods of reusing viscosified treatment fluids, methods of fracturing subterranean formations, and methods of gravel packing subterranean formations. The present invention also provides delinking compositions capable of delinking at least a portion of a crosslinked gelling agent; and a viscosified treatment fluid comprising water, a crosslinked gelling agent, and a delinking composition capable of delinking at least a portion of the crosslinked gelling agent wherein the delinking composition comprises a delinking agent.

    Abstract: The present invention involves methods of using particulates coated with a tackifying agent that need not be used immediately once they are prepared and that provide increased viscosity when placed into an aqueous fluid. The described methods include the steps of contacting particulates with a tackifying agent to create tackified particulates; contacting the tackifϊed particulates with a partitioning agent to form coated particulates that are capable of being stored for a time period, wherein the partitioning agent comprises a hydratable polymeric material; and, placing the coated particulates in an aqueous treatment fluid whereby the partitioning agent hydrates and increases the viscosity of the treatment fluid.
