Abstract

A seal apparatus is provided for use in a subterranean wellbore having a wellbore tubular (13) disposed therein. The wellbore tubular defines a wellbore surface (27). The seal includes a number of components which cooperate together. A conveyance tubular (17) is provided, which is positionable within the subterranean wellbore at a selected location relative to the wellbore surface. A sealing ring (19) is provided, and disposed about at least a portion of the conveyance tubular. The sealing ring has a first surface (31) proximate the conveyance tubular and a second surface (33) which is removed in distance from the conveyance tubular. The second surface defines a sealing surface, and includes a plurality of portions, with selected ones (91, 93, 95, 97, 99, 101, 103) of the plurality of portions of the sealing ring extending radially form the conveyance tubular in at least one radial dimension. The selected portions define at least one metal seal point for selectively and sealingly engaging the wellbore surface. The seal apparatus is operable in a plurality of modes, including a running mode of operation and a sealing mode of operation. In the running mode of operation, the seal ring is maintained in a radially-reduced position, out of engagement with the wellbore surface. In a sealing mode of operation the at least one metal seal point of the sealing ring is in sealing metal-to-metal engagement with the wellbore surface, providing a fluid-tight seal at a selected location between the conveyance tubular and the wellbore tubular. The seal apparatus of the present invention further includes an actuator member (21), which is selectively and remotely actuatable, for urging the sealing ring between the running and sealing modes of operation. <IMAGE>
