    摘要: 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.

    摘要: Methods for controlling lost circulation in subterranean wells, and in particular, fluid compositions and methods for operations during which the fluid compositions are pumped into a wellbore, enter voids in the subterranean-well formation through which wellbore fluids escape, and form a seal that limits further egress of wellbore fluid from the wellbore. The methods include preparing a carrier fluid containing compressed expandable foam that may be encapsulated. The carrier fluid is then placed into a lost-circulation zone, whereupon the foam expands to form a barrier that minimizes or blocks further ingress of carrier fluid. Lost-circulation control may be supplemented by introducing additional lost-circulation materials, pumping a cement slurry behind the foam-containing carrier fluid or both.
