Embodiments disclose a sand screen apparatus for use in a well that intersects a hydrocarbon formation. The sand screen apparatus comprises a composite, the composite having a compressed state and an expanded state. In embodiments, the composite comprises a base polymer and one or a plurality of reactive fillers where the reactive fillers react with the base polymer in the expanded state after exposure to a first trigger.
摘要:
A Moineau device includes a stator that interfaces to a rotor whereby fluid flows through cavities between the stator and rotor that progress axially as the rotor is rotated relative to the stator. At least one of the stator and the rotor is realized from a nanocomposite that includes a polymeric matrix with carbon nanotubes dispersed therein.
摘要:
A rubber pocket is described that is suitable for use on tubing, such as a packer-type seal, on casing, such as a cement-type seal, or on liners. The rubber pocket may contain cement particles, rubber particles, swellable particles, cement filled rubber particles, cement filled swellable particles, calcium oxide, magnesium oxide, magnesium sulfate, iron (III) oxide, calcium sulfoaluminate, clay, magnetic particles and/or reactants such as crosslinkers, retardants or epoxy. The particles may be bulk spheres, bulk fibers, hollow spheres, hollow fibers, etc. The rubber pocket or bladder may also be fully or partially filled with fluids such as polymer reactants. The pocket may also be empty or contain a small volume of reactants. The slurry or epoxy or other type of fluid and granular solid or injectable matter can be injected after the completion positioning downhole.
