摘要： Actuation and control of the deployment of a polymeric memory-shape material on a wellbore device on a downhole tool may be accomplished by treating a compacted or compressed polymeric memory-shape material with a deployment fluid to lower its Tg and/or decrease its rigidity, thereby softening the polymeric shape-memory material at a given temperature and triggering its expansion or recovery at a lower temperature. Alternatively, the deployment of the compacted or compressed polymeric memory-shape material may be prevented or inhibited by shielding the material with an environment of a fluid that does not substantially lower its Tg, decrease its rigidity or both, and then subsequently contacting the material with a deployment fluid.

摘要： A method for decomposing an asphaltene particle includes contacting the asphaltene particle with an intercalating agent and separating an asphaltene molecule from the asphaltene particle to decompose the asphaltene particle. Dispersing an asphaltene particle includes functionalizing the asphaltene particle and contacting the asphaltene particle with a solvent to disperse the asphaltene particle. Such asphaltene particle decomposition and dispersal can be used in a method for improving oil recovery that includes disposing a reagent in an oil environment; contacting an asphaltene particle with the reagent; decomposing the asphaltene particle to produce decomposed asphaltene; and displacing the decomposed asphaltene to improve oil recovery.
