Well process using a composite rod-stiffened pressurized cable

Patent ·
OSTI ID:5089778
This patent describes improvement in a process in which a wireline actuated well tool is run into a wellbore by a spooled cable. The improvement comprises: utilizing as the cable an internally fluid-pressurized flexible membrane member stiffened with parallel uni-directional composite rods spaced from each other and disposed axially on the outside of and in contact with the membrane, the pressurized membrane member being covered with an outer cylindrical flexible protective sheath separate from the membrane member, the combination forming a stiffened cylindrical cable having high resistance to buckling.
