摘要： Methods and treatments fluids for treating a wellbore. One example method introduces the treatment fluid into the wellbore. The treatment fluid comprises an aqueous fluid, an aminopolycarboxylic acid, a nanoparticle dispersed, and an organic solvent. The treatment fluid has a pH in a range between about 5 to about 9. The method further includes contacting a rock surface in the subterranean formation; wherein at least a portion of the rock surface is coated with a hydrocarbon. The treatment fluid removes a portion of the hydrocarbon from the rock surface and alters the rock surface to be water-wet.

摘要： The present disclosure relates to subterranean formation operations and, more particularly, to subterranean formation stabilization using self-assembled proppant monolayers. Specifically, the present disclosure provides a “hook-and-latch” process to stabilize a formation face, such as a fracture face, by facilitating the self-assembly of a monolayer of proppant particulates, including within complex fracture networks.

摘要： Methods and compositions for performing a sealing operation in a wellbore. An example method introduces a sealant composition into the wellbore while the sealant composition is under shear. The sealant composition comprises a thixotropic material, a conformance gel system, and an aqueous base fluid. The sealant composition is placed into a target location, and applied shear is reduced to the sealant composition when in the target location thereby allowing the sealant composition to thicken in the target location. Fluid flow across the target location is reduced by a fluid seal formed by the thickened sealant composition.

摘要： Suppressing passage of an aqueous fluid in a subterranean formation in preference to passage of an oleaginous fluid can often be desirable. Methods for suppressing the passage of an aqueous fluid in a subterranean formation, particularly a carbonate formation, can comprise: providing a treatment fluid comprising a carrier fluid and a relative permeability modifier comprising a reaction product of 1) an acrylamide polymer, any copolymer thereof, any derivative thereof, any salt thereof, or any combination thereof, and 2) a plurality of amine-containing compounds or any salt thereof, each amine-containing compound containing a primary amine, a secondary amine, or any combination thereof, and the amine-containing compounds being randomly reacted with at least a portion of the amide groups of the acrylamide polymer; and introducing the treatment fluid into a subterranean formation.

摘要： Methods and fluids for consolidating unconsolidated particulates. An example method introduces a furfuryl alcohol-based resin treatment fluid into a wellbore; wherein the furfuryl alcohol-based resin treatment fluid is a furfuryl alcohol-based resin and a diluent. The method contacts the unconsolidated particulates within the wellbore with the furfuryl alcohol-based resin treatment fluid to produce resin-contacted unconsolidated particulates. The method further introduces a substituted amine acid treatment fluid into the wellbore after the introduction of the furfuryl alcohol-based resin treatment fluid into the wellbore; wherein the substituted amine acid treatment fluid is a substituted amine acid salt and a solvent. The method further contacts the resin-contacted unconsolidated particulates with the substituted amine acid treatment fluid.

摘要： In a subterranean formation, complexation of metal ions can often be desirable in order to mitigate reactivity of the metal ions. However, many chelating agents used for this purpose are commercially manufactured in an alkali metal salt form that may not be entirely suitable for use downhole. The working pH range of some types of chelating agents may also be limiting. Accordingly, methods for treating a subterranean formation can comprise: providing an acidic treatment fluid comprising a sulfonated iminodiacetic acid; introducing the acidic treatment fluid into a subterranean formation; and at least partially dissolving an acid-reactive substance in the subterranean formation while complexing one or more metal ions with the sulfonated iminodiacetic acid.
