摘要： An apparatus 30 for isolating at least a portion of a tubular for use in a wellbore comprising a first, inner tubular in the form of carrier tube 32 and a second, outer tubular in the form of protective shroud 34, coupled to the carrier tube 32. One or more aperture 46 is provided in a wall of the carrier tube 32 for permitting fluid transfer through the tube 32 and one or more aperture 50 is provided to permit fluid transfer through the shroud 34. A seal member in the form of a sealing layer 36 is disposed on a surface of the shroud 34, the sealing layer 36 defining a first configuration permitting fluid flow through the apertures 46,50 and, on exposure to a selected reactant, adopting a second configuration to restrict fluid flow through the apertures 46, 50, the sealing layer 36 adapted to return from the second configuration to the first configuration where concentration of the selected reactant falls below a selected threshold. A method for producing an apparatus for isolating at least a portion of a tubular is also disclosed.
