Abstract

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.

Claims30

Dependent claims

A method comprising:

retracting a retractable segment of a tubular control conduit disposed in a wellbore leaving an abandoned segment of the tubular control conduit, each of the retractable segment and the abandoned segment having an inner bore;
and
actuating an obstruction member, the obstruction member forming a seal and preventing a flow of fluid past the obstruction member out from the inner bore of the abandoned segment upon actuation.

Dependencies are inferred from the claim text.
