    摘要: Apparatus, methods and systems for preparing a polymer concentrate for treating a formation with slick water systems viscous fluid or a gelled viscous fluid are disclosed. The method includes directing a powdered gel into a vortex mixing chamber, while directing a first portion of a base fluid into the vortex mixing chamber to form partially hydrated fluid concentrate. The partially hydrated fluid concentrate is then sucked or sweep into a main portion of base fluid for form the slick water systems viscous fluid or gelled viscous fluid.

    摘要: Methods and compositions are provided for making a solid material for controlling the release of at least one reactant of an exothermic reaction into a carrier fluid. The method comprises the steps of: (a) mixing a reactant with a polymeric material, wherein the polymeric material is capable of being hydrated, and water, wherein the proportion of water is insufficient to substantially hydrate the polymeric material but is sufficient to make the polymeric material sticky to help bind the reactant into a matrix; and (b) drying the mixture. According to a similar aspect, methods and compositions are provided for making a solid material for use in controlling the release of a catalyst of an exothermic reaction into a carrier fluid for increasing the temperature of a section of conduit used for the production or transmission of hydrocarbon. According to other aspects, the reactant or catalyst is mixed with a binder.
