Abstract: A bailer bottom, bailer system, and method for performing bailer operations at a wellsite are disclosed. The wellsite is positioned about a wellbore penetrating a subterranean formation. The bailer bottom is deployable in the wellbore. The bailer bottom includes a plurality of downhole components and a select fire unit. The plurality of downhole components includes a cement unit which includes a cement chamber and a valve. The cement chamber has a port therethrough in selective communication with the wellbore via the valve. The select fire unit includes a downhole switch electrically coupled to the plurality of downhole components. The downhole switch has a polarity for each of the plurality of downhole components. The downhole switch is triggerable to selectively move between the multiple polarities to selectively pass a signal to one of the plurality of downhole components whereby the plurality of downhole components are selectively activated.

Abstract: A well tool with multi-stage remedial system improves the durability of a subterranean well tool having an expanded elastomeric member, such as a packer, for use inside a tubular member. The well tool with multi-stage remedial system has a plurality of mandrel members shiftable within the tubular member for anchoring and for setting the seal system. A floating tandem mounted annularly around the lower mandrel members has one end (upon shifting) proximate an end of the seal system, and the floating tandem has an opening to ambient bottom-hole-pressure of the subterranean well. A locking tandem is interposed with the floating tandem and at least one of the lower mandrel members. The floating tandem and the locking tandem together assist in abating elastomeric member extrusion under high temperature, high pressure environments as well as other conditions lending to failure within the well.
