    摘要: The disclosure relates to a system (10) for improving zonal isolation in a well in a subterranean formation, comprising: a tubular (1) having a outer surface (11); and a swellable coating (2) coating the outer surface (11) of said tubular (1), said swellable coating (2) having an external surface (21); and/or a composition (20) provided in an annular space outside said tubular (1). The swellable coating (2) is made of a first swellable material (3) able to swell in contact with a first fluid (6) on said external surface (21) and/or the composition (20) is made of a second swellable material (4) able to swell in contact with a second fluid (7), and wherein said first (3) and/or said second (4) swellable materials include an elastomer compounded with an aqueous inverse emulsion of particles of a polymer comprising a betaine group, said elastomer being able to swell in contact with hydrocarbon and saline aqueous fluids.

    摘要: A system for improving zonal isolation incorporates a tubular having an outer surface and a swellable coating that coats the outer surface. The swellable coating has an external surface, a composition provided in an annular space outside the tubular, or both. The swellable coating is made of a first swellable material that can swell when contacted by a first fluid on the external surface. The composition is made of a second swellable material that can swell when contacted with second fluid. The first swellable material, the second swellable material, or both, include an elastomer that is compounded with an aqueous inverse emulsion of particles of a polymer comprising a betaine group. The elastomer is able to swell when contacted by hydrocarbons and saline aqueous fluids.
