Abstract: Methods of enhancing well production, including enhancing fluid flow by conductivity enhancement, diversion, and fluid-loss control, are described. The method of enhancing fluid flow includes introducing a fracturing fluid including resin-coated proppant particles into the formation; introducing (i) a thermosetting composition including one or more di- or tricarboxylic acids and one or more epoxidized fatty acid esters or (ii) thermoset particulates comprising an anhydride network of one or more epoxidized fatty acid esters cross-linked with one or more di- or tricarboxylic acids, into the formation; allowing the resin-coated proppant particles and (i) the thermosetting composition or (ii) the thermoset particulates to form a proppant matrix in a fracture; and allowing voids to form in the proppant matrix.

Abstract: A persulfate compound activated by a strong base is used for low-temperature breaking of fluids viscosified with a multi-chain polysaccharide. The breaker system can be used in an oilfield or pipeline application where a multi-chain polysaccharide may be used in a fluid.

The breaker system can be used in an oilfield or pipeline application where a multi-chain polysaccharide may be used in a fluid. It is particularly useful at low temperatures of less than 100° F. Optionally, the water can be a brine.

Abstract: A method of treating a portion of a well of a well. The method includes the step of forming a treatment fluid comprising: (i) a continuous aqueous phase; (ii) a viscosity increasing agent selected from the group consisting of diutan, clarified diutan, water-soluble derivative of diutan, and any combination thereof, wherein the viscosity-increasing agent is dissolved in the aqueous phase; and (iii) a breaker comprising oxalic acid, wherein the oxalic acid is dissolved in the aqueous phase. The viscosity of the treatment fluid breaks to less than 3.0 cP in less than 72 hours when in a temperature range of 180° F. (82.2° C.) to 220° F. (104.4° C.). The method also includes the steps of introducing the treatment fluid into the portion of the well and flowing back from the portion of the well.

Abstract: A method of gravel packing a treatment zone of a well includes the steps of: (A) forming a treatment fluid including a continuous aqueous phase and gravel, wherein the aqueous phase includes: (i) water; (ii) diutan; (iii) oxidizer in the range of 0.1% to 2% by weight of the water; (iv) organic acid in the range of 0.5% to 5% by weight of the water; and (v) transition metal compound in the range of 0.001% to 0.25% by weight of the water; and (B) introducing the treatment fluid into the treatment zone; wherein the design temperature is less than 180° F.; wherein the continuous phase of the treatment fluid has a viscosity in the range of 10 cP to 75 cP at the design temperature; and wherein the concentration of the organic acid is less than would cause the diutan to salt out at the design temperature.
