Method and system of providing or enabling cap rock restoration of at least a portion of a producible zone of a subterranean well by placing and supporting at least one cement equivalent well barrier member within an operable usable space, formed by at least one cable operable and rig-less string operable, annulus engagable member, comprising cable and rig-less string conveyable components that are conveyed through an innermost passageway and downward from a wellhead and using energy, conductible through said rig-less string or through movable fluid of a circulatable fluid column, to operate or access at least one annulus from said innermost passageway and displace at least one portion of a wall of at least one conduit about said innermost passageway, to provide at least one cement equivalent well barrier. |

1. A method (1A-1BU) of providing (220) or enabling (211-219) restoration of cap rock of at least a portion (4A-4BU) of a producible zone of a subterranean well, the method comprising the steps of:
placing and supporting at least one cement equivalent well barrier member (3A-3BU, 20, 216) within an operable usable space formed by at least one cable operable and rig-less string operable, annulus engagable member (2A-2BU) comprising components that are cable and rig-less string conveyable through an innermost passageway (25, 25E, 25AE) surrounded by at least one annulus of a plurality of annuli formed by installed conduits (11, 12, 14, 15, 15A, 19) extending downward from a wellhead (7) within subterranean strata (17) for forming a plurality of passageways (24, 24A, 24B, 24C, 25, 25E, 25AE) in fluid communication with said producible zones through said cap rock; using energy conductible through said rig-less string or through movable fluid of a circulatable fluid column (31C) within said plurality of passageways to operate said at least one annulus engageable member; and using said at least one annulus engagable member to access said at least one annulus from said innermost passageway, displace at least one portion of a wall of at least one conduit about said innermost passageway to provide an operable space, bridge across said operable space, and place said at least one cement equivalent well barrier member through said operable space adjacent to said cap rock to form at least one geologic time-frame space usable to fluidly isolate said at least one portion of said subterranean well without removing said installed conduits and associated debris from below one or more subterranean depths (218) of associated capping rock to provide or enable said restoration of said cap rock above said producible zone. |
