Abstract: Treatment compositions include a mixture of a corrosion inhibitor and a functionalized particulate in a solvent. The functionalized particulate includes both epoxy and amine groups. Surfaces coated with the treatment composition have improved corrosion inhibition performance, and/or greater duration of corrosion inhibition performance with respect to corrodents such as CO2 and H2S when compared to the corrosion inhibition performance of the same corrosion inhibitor coating in the absence of the functionalized particulate. The coatings including functionalized particulate are usefully applied to one or more interior and/or exterior surfaces of containments, separators, conduits, and other equipment, such well string completion components, that are contacted by fluids containing corrodents.

Abstract: Methods for treating a producing wellbore of a subterranean reservoir include obtaining a side stream flow of a produced fluid from a production tube of the wellbore at a location above the surface of the earth; providing an eluting contact of the side stream flow of produced fluid with a treatment material to form a side stream flow of treated produced fluid; and directing the side stream flow of treated produced fluid into the wellbore at a point below the surface of the earth. Apparatuses suitable for carrying out the methods include an elution device fluidly connected to a side stream of produced fluid flowing above the surface of the earth and situated to direct the side stream toward the elution device to provide an eluting contact of the produced fluid with a treatment material disposed in the elution device, then direct the treated produced fluid into the wellbore.

Abstract: Treatment compositions including a corrosion inhibitor having an amine group and a particulate including Al2O3 are coated on a surface to impart corrosion inhibition thereto. The coated surfaces have improved duration of corrosion inhibition performance with respect to corrodents such as CO2 and H2S when compared to the corrosion inhibition performance of the same corrosion inhibitor coating but in the absence of the particulate including Al2O3. The coatings are usefully applied to one or more interior and/or exterior surfaces of containments, conduits, and other equipment, such well string completion components, that are contacted by produced fluids containing corrodents.

Abstract: A polymer composition has been developed that provides low viscosity oil-in-water polymer emulsions that release the polymer in the emulsion at a faster rate and without an additional surfactant when the emulsion is added to a hydrocarbon stream. Use of a temperature-sensitive emulsifying surfactant facilitates inversion of the oil-in-water polymer emulsion when applied to a hydrocarbon composition at a temperature sufficiently high to destabilize the emulsion. These compositions are particularly useful as drag reducers for delivery to a subsea flowline via an umbilical line.
