  • Publication number: 20080105428
    Abstract: A method of serving a wellbore comprising placing a slurry composition comprising an alkaline metal oxide, a chloride or phosphate salt, water, glass beads and a foaming agent into a wellbore and allowing the composition to set. A method of servicing a wellbore comprising foaming a slurry comprising magnesium oxide, water, a chloride or phosphate salt, and glass beads, wherein the slurry has a density of from about 4 to about 12 pounds per gallon, placing the slurry in a wellbore, and allowing the composition to set. A method of temporarily plugging a wellbore comprising placing in the wellbore a cement slurry comprising magnesium oxide, water, a chloride or phosphate salt, a foaming agent and beads, wherein the slurry has a density of from about 4 to about 12 pounds per gallon, allowing the composition to set, and removing the composition by contacting the set composition with acid.

  • Publication number: 20080066916
    Abstract: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Acidic internal breakers such as sulfuric acid and nitric acid are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger.

  • Patent number: 7131495
    Abstract: A method to synthesize a chlorine dioxide block remover in a well is described. The method includes dissolving a chlorate aqueous solution and some acidic substances in water and to produce a hydrogen ion. The chlorate aqueous solution and acidic substances are quickly injected into the well by an injection pump, so they react with each other and produce chlorine dioxide. The synthesis of the chlorine block remover in the well removes oil layer blocks induced by polymers and microbes, while reducing the risk of explosion caused by leaked chlorine dioxide, and reducing the corrosion of equipment and pipes caused by chlorine dioxide.
