Methods and devices for multi-interval zonal isolation are disclosed. An isolation tool assembly adapted to provide zonal isolation includes a tubular member, a swellable packer disposed around the tubular member, and a plurality of rubber elements disposed around the tubular member. The isolation tool assembly further includes a sliding sleeve disposed within the tubular member, wherein the sliding sleeve is operable to slide in response to an annular pressure differential. The isolation tool assembly further includes a top sub coupled to the tubular member and adjacent one or more expansion devices, and a bottom sub coupled to the tubular member. |
