TAM’s inflatable CAPs and FREECAP swellable packers can be effectively utilized as redundant liner top sealing mechanisms to ensure viable annular isolation is achieved in highly deviated or other challenging liner applications. Swellable packers can be constructed with a less than ¾ in. (19.05 mm) OD increase over liner diameters, thus minimizing the impacts on equivalent circulating densities (ECDs) during primary pumping operations. Subsequently, they provide a secondary barrier to annular gas or fluid migration to the previous casing string once activated.
