Claim 11:
12. A system for forming multiple layers of seal in an open-hole wellbore, the system comprising:
a sealing assembly comprising:
at least one element comprising a first expandable sealing element and a second expandable sealing element;
a sealing mixture; and
a container housing positionable between the first expandable sealing element and the second expandable sealing element for retaining the sealing mixture that is releasable, in response to the system being actuated, from the container housing (i) to directly contact a wall of the open-hole wellbore for pressure sealing the open-hole wellbore between the at least one element and the container housing and (ii) for providing multiple layers of seal, wherein differential pressure is receivable by a plurality of pistons to form the multiple layers of seal, and 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 system in an expanded state; and

the tubing comprising the retaining mechanism for retaining the system after the system expands.
