Latest Patents

Barrow’s latest listed patents address equipment and methods for running tubing hangers and upper completions in subsea wells.

“Passively Motion Compensated Tubing Hanger Running Tool Assembly” describes a running-tool assembly with pressure-testing capability and a pressure-containing slip joint. The joint has concentric inner and outer mandrels that slide relative to one another, allowing compression and extension along a linear axis. Seals between the mandrels help contain pressure.

“Method of Running a Passively Motion Compensated Tubing Hanger Running Tool Assembly” describes using such an assembly to run a tubing hanger and upper completion in a subsea well at the seafloor. The pressure-containing slip joint provides passive heave compensation during the operation.
