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:
The present invention provides methods of preparing and using viscous gelled well treating fluids devoid of insoluble gelling agent residue and compositions. A viscous gelled treating fluid composition devoid of insoluble gelling agent residue basically comprises water, a hydrated gelling agent and the water insoluble residue therefrom, a base for raising the pH of the water so that the water insoluble residue is dissolved therein, and additional water to lower the amount of the gelling agent in the treating fluid relative to the amount of water therein and to lower the pH thereof.

Abstract:
The invention is for a method of forming and delivering a treatment fluid into a wellbore. In one aspect, a method is provided for pumping a first fluid having a relatively high concentration of a particulate suspended therein and pumping a second fluid having either none of the particulate or a relatively low concentration of the particulate suspended therein, and then merging at least the first and second fluids to form a treatment fluid having a merged concentration of the particulate. According to this aspect, the first fluid has a relatively high concentration of a hydratable additive and the second fluid has either none or a relatively low concentration of the hydratable additive.
Abstract:
The inventions are for methods of forming and delivering a treatment fluid into a wellbore. In one aspect, methods are provided of using higher-quality water for one portion of the water for a treatment fluid and lower-quality water for another portion of the water for a treatment fluid, and merging the two portions to form the treatment fluid after pumping the fluid portions toward the wellbore. This allows the use of lower-quality water for some of the water required for making up the treatment fluid.
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.
