Claim 7:
8. A method comprising:
positioning a sealing assembly downhole in an open-hole wellbore, the sealing assembly comprising (i) at least one element having a first expandable sealing element and a second expandable sealing element and (ii) a container housing positioned between the first expandable sealing element and the second expandable sealing element, the container housing comprising a sealing mixture;
applying differential pressure to a plurality of pistons of the sealing assembly to release the sealing mixture from the container housing (i) to cause the sealing mixture to directly contact a wall of the open-hole wellbore for pressure-sealing the open-hole wellbore and (ii) to form multiple layers of seal between the at least one element and the container housing, wherein the plurality of pistons, in response to receiving the differential pressure, cause the sealing assembly to expand such that retaining teeth of at least two retainer rings, which are positionable adjacent to a tubing around which the sealing assembly is positionable, contact a retaining mechanism of the tubing to retain the sealing assembly in an expanded state; and
performing wellbore-related tasks in the pressure-sealed open-hole wellbore.
