    摘要: Methods for stimulating a high-permeability subterranean formation are disclosed. In one embodiment, a method comprises the step of selecting a target fracture geometry for a portion of a subterranean formation. The method further comprises the step of introducing a pad fluid comprising a fluid-loss-control additive into the portion of the subterranean formation to create or extend one or more fractures in the portion of the subterranean formation, wherein an amount of the fluid-loss-control additive is determined based at least in part on the target fracture geometry. The method further comprises allowing a barrier to form along at least a portion of the one or more fractures, wherein the barrier comprises the fluid-loss-control additive. The method further comprises introducing a slurry fluid comprising proppant particulates into the one or more fractures, wherein a tip screen-out occurs in at least one of the one or more fractures.

    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.
