Abstract: Systems and methods that use far-field diverting agents and proppant pulsing to enhance fracture geometries in far field areas of a subterranean formation are provided. In one embodiment, the methods comprise: introducing into a well bore penetrating a portion of a subterranean formation alternating stages of a proppant-carrying fracturing fluid comprising a plurality of proppant particulates, and a clean fracturing fluid comprising a lesser concentration of proppant particulates than the proppant-carrying fracturing fluid, wherein the alternating stages of the proppant-carrying fracturing fluid and the clean fracturing fluid are introduced into the well bore at or above a pressure sufficient to create or enhance one or more fractures in the subterranean formation; and introducing a diverting agent into the well bore during one or more of the alternating stages of proppant-carrying fracturing fluid and clean fracturing fluid.

Abstract: Embodiments including methods comprising providing a treatment fluid comprising a first aqueous base fluid and a polymeric gelling agent, wherein the treatment fluid comprises a first surface tension; introducing a fluid mobility modifier into the treatment fluid, wherein the fluid mobility modifier comprises: a first surfactant selected from the group consisting of a non-ionic surfactant; a cationic surfactant; and any combination thereof, and a solvent-surfactant blend comprising a second aqueous base fluid, a second surfactant, a solvent, and a co-solvent, wherein the ratio of the first surfactant to the solvent-surfactant blend is in the range of between about 1:5 to about 5:1, wherein the fluid mobility modifier causes the treatment fluid to adopt a second surface tension that is less than the first surface tension; and introducing the treatment fluid into a subterranean formation.

Abstract: An oilwell treatment composition comprising (i) a solubilizing agent wherein the solubilizing agent comprises a saturated compound of the formula: H—(OCaH2a)x(OCbH2b)y—OCcH2c+1 where a and b are each independently 1, 3, or 4; c is 1, 2 or 3; x and y each independently, are numbers ranging from 1 to 5; (ii) a solid acid precursor and (iii) an aqueous fluid wherein the mass ratio of the solubilizing agent to the aqueous solution is within the range of about 1:3 to about 1:5 and the mass ratio of the solubilizing agent to the solid acid precursor is within the range of about 3:1 to about 2:1.

Abstract: Methods including providing resin double-coated proppant comprising proppant coated with a first resin and thereafter coated with a second resin atop of the first resin; wherein the first resin is curable by a first curing agent and wherein the second resin is curable by a second curing agent that is different than the first curing agent; curing the second resin by exposing it to the second curing agent; introducing the resin double-coated proppant into at least a portion of a fracture within a subterranean formation; breaking the cured second resin to expose the first resin; introducing the first curing agent into the portion of the fracture where the resin double-coated proppant was placed; and curing the first resin by exposing it to the first curing agent to form a proppant pack.
