    摘要: A method of making a proppant is provided, wherein the method includes the steps of: (a) forming a particulate comprising: (i) a binder; and (ii) a filler; and (b) sintering the particulate to form a sintered proppant, wherein the sintered proppant comprises: (i) at least 20 wt % of alkaline earth oxide equivalent; and (ii) at least 20 wt % of silicon dioxide equivalent. A method of treating (e.g., fracturing) a subterranean formation is provided, the method including the steps of: (a) suspending a sintered proppant in a treatment fluid, wherein the sintered proppant comprises: (i) at least 20 wt % of alkaline earth oxide equivalent; and (ii) at least 20 wt % of silicon dioxide equivalent; and (b) introducing the sintered proppant into the subterranean formation (e.g., into a fracture). In addition, a sintered proppant is provided comprising: (i) at least 20 wt % of alkaline earth oxide equivalent; and (ii) at least 20 wt % of silicon dioxide equivalent. The sintered proppant is made with a raw material selected from the group consisting of: unhydrated cement, hydrated cement (e.g., construction cement or concrete waste), kiln dust, fly ash, limestone, lime, talc, olivine, dolomite, clay that contains a substantial concentration of alkaline earth oxide equivalent, and any combination thereof in any proportion.

    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.
