    摘要: This invention relates to subterranean treatment operations. More particularly, this invention provides methods that may be useful in providing void-free barriers between a subterranean formation and a portion of a well bore. A nonlimiting example of a method is a method of degrading a filter cake in a subterranean formation. Another nonlimiting example of a method is a method of producing hydrocarbons from a subterranean formation.

    摘要: Methods and compositions are provided for treating a subterranean formation penetrated by a well. The method includes the steps of: (a) forming a treatment fluid, and (b) introducing the treatment fluid into the well and into contact with the formation. The treatment fluid includes: (1) water; (2) a water-soluble polysaccoharide capable of increasing the viscosity of the water or a water-soluble polysaccharide and a crosslinking agent for the water-soluble polysaccharide; (3) a breaker comprising at least one member selected from the group consisting of a source of chlorite ions and a source of hypochlorite ions; and (4) a breaker moderator comprising at least one member selected from the group consisting of a source of magnesium ions and a source of calcium ions.

    摘要: Methods are provided for increasing the temperature of a section of conduit used for the production or transmission of hydrocarbon. According to one aspect, the method includes the steps of: (a) forming a treatment fluid comprising: (i) a carrier fluid; and (ii) a first reactant and a second reactant; and (b) introducing the treatment fluid into a section of conduit used for the production or transmission of hydrocarbon. The first reactant and second reactant are selected for being capable of reacting together in an exothermic chemical reaction; and the first and second reactant are in at least sufficient concentrations in the carrier fluid to generate a theoretical heat of reaction of at least 1,000 kJ/liter of the treatment fluid. At least some of at least one of the first reactant and the second reactant is suspended in the carrier fluid in a solid form that is adapted to help control the release of the reactant into the carrier fluid.
