    Abstract: The present invention involves coated proppant slurries and using such slurries in subterranean applications such as production enhancement and sand control. More particularly, the present invention relates to stable resin-coated proppant suspensions that need not be immediately used once they are formed. Some embodiments of the present invention provide methods of creating a stable slurry of coated particulates wherein the slurry is capable of being stored for at least 2 hours before use comprising the steps of: providing resin coated particulates wherein the resin comprises a resin that does not completely cure unless it is at least one of exposed to a temperature above about 175° F. or exposed to an external catalyst; and, substantially suspending the resin coated particulates in a servicing fluid to create a stable resin coated particulate slurry. Other embodiments of the present invention provide methods of creating a stable slurry of coated particulates wherein the slurry is capable of being stored for at least 2 hours before use comprising the steps of: providing tackifyer coated particulates; and, substantially suspending the tackifyer coated particulates in a servicing fluid to create a tackifyer coated particulate slurry.

    Abstract: Treating fluid production and subterranean formation treating methods as well as treating fluid compositions that reuse at least part of a prior treating fluid, particularly a fluid having one or more constituents that can be relinked. This includes conditioning a selected at least partially delinked flow-back fluid recovered from a first treating fluid pumped into a well, such that the conditioned selected at least partially delinked flow-back fluid provides a constituent for a second treating fluid. Also included are pricing considerations. A composition for a treating fluid includes a treating fluid residual recovered from a well, preferably a conditioned treating fluid residual. Examples of such compositions include fracturing fluids and gravel pack fluids.
