The cleavable surfactants useful in the present invention comprise at least one weak chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscoelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscosifying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations.

  • Publication number: 20140256604
    Abstract: A treatment fluid and method treating a zone of a subterranean formation penetrated by a wellbore. The treatment fluid includes: (i) water; (ii) a strong acid; (iii) a cationic viscoelastic surfactant; (iv) an anionic organic component having at least 4 carbon atoms; and (v) a non-cationic corrosion inhibitor; wherein the pH of the treatment fluid is less than 0.5. Preferably, the viscosity of the treatment fluid is less than 5 cP at 40 sec-1. The method includes the steps of: (A) forming the treatment fluid; (B) introducing the treatment fluid through the wellbore into the zone; and (C) allowing time for the strong acid in the treatment fluid to spend in the formation. Preferably, as the acid spends in the subterranean formation, the viscosity of the treatment fluid increases in the well to above 5 cP. Such a treatment fluid shows good rheological properties at temperatures above 93° C. (200° F.).

  • Publication number: 20140243246
    Abstract: A method for improving the performance of fracturing processes in oil production fields may rely on polymer coated particles carried in the fracturing fluid. The particles may include heavy substrates, such as sand, ceramic sand, or the like coated with polymers selected to absorb water, increasing the area and volume to travel more readily with the flow of fluid without settling out, or allowing the substrate to settle out. Ultimately, the substrate may become lodged in the fissures formed by the pressure or hydraulic fracturing, resulting in propping open of the fissures for improved productivity.

  • Publication number: 20140179568
    Abstract: Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine derivative of the formula: wherein R14 is a C1-C24 straight chain or branched alkyl group; or a C6-C24 aryl or arylalkyl group; R15 is a C1-C6 alkyl or a C6-C30 aryl or alkylaryl group; and X is chlorine, bromine or iodine. The dithiazine may be isolated from a whole spent fluid (WSF) formed by reaction of hydrogen sulfide and a triazine. Alternately, the whole spent fluid containing dithiazine or dithiazine derivative and a corrosion inhibiting formulation may be used to inhibit corrosion in the well.

    Abstract: The present invention relates to a method of obtaining and using foaming compositions with wettability-modifying and corrosion inhibitory properties that control the channeling of fluids in naturally fractured carbonate reservoirs, favorably alter the rock wettability in crude oil enhanced recovery processes and control uniform corrosion problems occurring in production rigs under high temperature and ultra-high salinity conditions by the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates having the formula (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and are suitable for use in the reservoir, seawater and/or congenital water characteristic of the reservoir for transporting the crude oil from the reservoir.
