Abstract: A method is provided for treating at least a portion of a subterranean formation. The method includes introducing a treatment fluid including a composite particle, which includes proppant incorporated into or attached to a swellable material and/or swellable materials, into a subterranean formation via a wellbore; and increasing the buoyancy of the composite particle including proppant by either mixing it with a treatment fluid or mixing it with a treatment fluid and triggering the swellable material and/or swellable materials to swell.

Abstract: A method and system for delivering materials downhole employing a shear thickening treatment fluid. The viscosity of the shear thickening treatment fluid increases with increasing shear rate. The shear thickening fluid may inhibit particulate dispersion, settling or a combination thereof at high shear rates and facilitate dispersion and/or settling of the particulates and/or formation of pillars or clusters in the fracture at low shear rates.

Abstract: Methods include combining an amount of water and an acid retarding agent (RA), where the amount of water is present in an amount up to about 5 times the mass of the RA, inclusive, and wherein the RA includes at least one salt compound. An amount of acid is dissolved in the combined amount of water and RA to form a composition, where the amount of acid is a molar ratio of acid:RA of between 4.0 and 0.2, inclusive, and wherein the amount of acid is up to about 36% by weight of total weight of the composition. The composition is injected into a wellbore penetrating a subterranean formation at a pressure, which may be less than the fracture initiation pressure of the subterranean formation in some cases, while in other cases equal to or greater than the fracture initiation pressure.

Abstract: An aqueous composition comprising a mineral acid, a fixing agent and water present in an amount sufficient to dissolve the mineral acid and the fixing agent. The fixing agent comprises at least one of an amine and/or an amide containing compound having a dipole moment of at least 3 when in the aqueous composition.
