A tubular control conduit is disposed in a wellbore having a retractable segment and an abandonable segment, each having an inner bore. Upon retraction of the retractable segment an obstruction member is actuated to form a seal thereby preventing the flow of fluid past the obstruction member in the inner bore of the abandoned segment. Cement is then poured into the wellbore thereby covering the abandoned segment of the tubular control conduit.

Actuatable obstruction member for control lines

Apparatus can have a separable housing having a longitudinal length extending along a longitudinal axis with an upper portion and a lower portion. One or more tubular control conduits can be disposed within the separable housing and extend along the longitudinal axis. The one or more tubular control conduits can have an inner bore formed therein. One or more actuation elements can be coupled with the separable housing and be operable to separate the upper portion and the lower portion of the separable housing. The one or more actuation elements can also be operable to separate the one or more tubular control conduits, thereby interrupting the inner bore of the one or more tubular control conduits.

Separable housing assembly for tubular control conduits

A control system can include a resettable chamber and a bidirectional valve. The bidirectional valve can be switchable between (i) a first configuration for enabling fluid flow from the control line into a first port of a well tool and from a second port of the well tool into the resettable chamber, and (ii) a second configuration for enabling fluid flow from the control line into the second port of the well tool and from the first port of the well tool into the resettable chamber. The bidirectional valve can be switched from the first configuration to the second configuration in response to pressure being applied to the control line.
