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.

摘要： A method is provided of sealing an annular space between an expandable tubular element arranged in a wellbore and a wall surrounding the expandable tubular element. A pressure difference occurs between a first location in the annular space and a second location in the annular space axially spaced from the first location. The method comprises: installing the tubular element in the wellbore; locating a body of fluid in the annular space between the first and second locations, the fluid having a yield strength selected such that the pressure difference is insufficient to induce axial flow of the body of fluid in the annular space after radial expansion of the tubular element; and radially expanding the tubular element.

摘要： A method of opening an orifice in a downhole article includes forming a downhole article having an orifice, the orifice having a selectively removable plug sealingly disposed therein, the selectively removable plug comprising a selectively removable plug body formed of a plug body material and a selectively removable sealant coating formed of a coating material disposed on an outer surface thereof. The method also includes disposing the article within a wellbore. The method further includes exposing the selectively removable plug to a first wellbore fluid that is configured to selectively remove the sealant coating and provide a fluid access to the plug body. The method also includes exposing the selectively removable plug body to a second wellbore fluid through the fluid access that is configured to selectively remove the plug body.
