  • Patent number: 9394473
    Abstract: Methods for servicing subterranean wells are disclosed. Particularly, the use of a fiber-laden fluid to separate and prevent the commingling of two stationary process fluids after placement in the borehole of a subterranean well, or in a tubular body installed in a subterranean well. The fiber-laden fluids prevent the cement plug from descending through drilling fluid to the bottom of the well. It obviates the need for mechanical devices such as packers, or special adjustment of the process fluids' rheological properties.

  • Publication number: 20100314113
    Abstract: Incorporating water-based polymer breakers, such as oxidizers, enzymes and/or acids, into a mixture of an oil and oil-soluble surfactants creates an emulsion that can then perform as a dual-functional breaker for reducing the viscosity of hybrid fluids gelled with both a viscoelastic surfactant (VES) and a polymer. The outer phase of the dual-functional breaker emulsion is oil, e.g. a mineral oil, containing an oil-soluble surfactant that will, over time and with heat, break the VES portion of the gel. As it does so, the polymer breaker in the internal aqueous phase will be released to then break the polymer portion of the gel. The polymer breaker will not start to break the polymer gel before the oil-soluble surfactant starts to break the VES gel. The overall breaking using the emulsion is slower as compared to introducing the polymer breaker and the oil-soluble surfactant in a non-emulsified form.

  • Patent number: 7803744
    Abstract: An aqueous viscoelastic surfactant (VES) fluid foamed or energized with carbon dioxide, in which the VES is more compatible with the carbon dioxide, is made by the addition of one or more than one synergistic co-surfactant. The synergist co-surfactant includes quaternary amines and ethoxylated carboxylates having a hydrophobic chain shorter than the hydrophobic chain of the VES. Improved compatibility is evidenced for a given surfactant concentration either by formation and maintenance of a foam under conditions at which the foam could not otherwise have been formed or maintained, or by either higher viscosity of the foamed fluid at a given temperature or longer foam life at a given temperature or a higher temperature at which useful fluid viscosity can be generated or maintained for a useful time. The aqueous carbon dioxide foamed fluids may be used in acidizing, acid fracturing, gravel packing, diversion, and well cleanout.

  • Patent number: 7795184
    Abstract: A method of altering the properties of a drilling fluid includes adding effective amounts of crushed or whole oilseeds or mixtures of crushed or whole oilseeds to a drilling fluid. The crushed or whole oilseeds or mixture of crushed or whole oilseeds are selected to impart any one of or a combination of effects including but not limited to: an increase in drilling fluid emulsion stability in oil-based or invert emulsion fluids, decreased specific gravity of the drilling fluid, seepage loss control, filtration control, oil wetting and deflocculation/dispersion, of entrained solids and/or reduced torque and drag of the drilling string.

  • Patent number: 7749944
    Abstract: Methods of improving shear recovery time of viscoelastic surfactant fluid systems are described, one method involving providing a viscoelastic surfactant fluid system comprising a major portion of a surfactant and a rheology enhancer in a concentration sufficient to shorten shear recovery time of the fluid system compared to shear recovery time of the fluid system absent the rheology enhancer, the rheology enhancer selected from aromatic sulfonates having a molecular weight of at least 500; and injecting the fluid system down a well. The rheology enhancer may be a lignosulfonate derived from wood pulping. Viscoelastic surfactant systems including the rheology enhancer are also described.

  • Publication number: 20100167965
    Abstract: Methods and compositions for forming a hydraulic fracture are disclosed herein. The methods and compositions make use of novel amphiphobic proppants. The amphiphobic properties of the disclosed proppant compositions provide several advantages over existing solutions. The hydrophobic nature of the proppant enhances recovery of fracture fluid from the fracture as well as prevents liquid build-up with the fracture. Additionally, the lipophobic nature of the proppant may enhance production of hydrocarbons from the fracture.

  • Patent number: 7741247
    Abstract: A region of a borehole with one or more openings to be sealed off, such as one or more fractures, voids, and or pores, may or may not be sealed off around a tubular string with a borehole seal such as a packer or plug. A carrying fluid may be utilized to transport a filtration material into the opening to create a bridge, which at least partially seals the opening, but still provides a flow path that permits fluid flow therethrough. A solid material and/or settable material may then utilize the fluid flow subsequently or be simultaneously spotted with or behind the filtration material to thereby form compositions which effectively seals off the flow path into the one or more openings.
