    摘要: A swellable article, including a matrix material and an exfoliatable graphene-based material disposed in the matrix material. The exfoliatable graphene-based material is operatively arranged to facilitate swelling of the swellable article upon exposure to a selected fluid by sorbing particles in the fluid. The swelling enables the swellable article to engage an adjacent structure. Methods of making and using a swellable article are also included.

    摘要: A method for decomposing an asphaltene particle includes contacting the asphaltene particle with an intercalating agent; and reacting the intercalating agent to increase a distance between asphaltene molecules in the asphaltene particle to decompose the asphaltene particle. In a method for producing decomposed asphaltene, the method includes disposing an intercalating agent in an oil environment; contacting an asphaltene particle in the oil environment with the intercalating agent; reacting the intercalating agent to produce product molecules; and decomposing the asphaltene particle to produce decomposed asphaltene.

    摘要: The swelling rate of a swelling packer element or a conforming foam screen material is accelerated with heat. Ferromagnetic particles or electrically conductive resins or polymers are interspersed in the swelling material and heat is generated at the particles by an inductive heater. A dielectric mandrel or base pipe can be used to focus the heating effect on the ferromagnetic particles or the electrically conductive resins or polymers in the sealing element or swelling foam screen element to focus the heating there without heating the base pipe. The heat accelerates the swelling process.
