Completion & Intervention

Subsea safety systems during completions and well interventions are necessary to provide a barrier to the well in case drift-off/drive-off or well-control issues arise. The large-bore systems are run with either horizontal or vertical trees and integrated with the tubing hanger running tool to enable control of the upper completion.

Halliburton offers both Veto™ 6 (a 6-3/8 system rated to 15,000 psi), and Veto 7 (a 7-3/8 ID system rated to 10,000 psi), for any and all completion landing string needs. Both large-bore systems are direct hydraulic, dual-barrier systems consisting of a lubricator valve, retainer valve, and subsea safety tree.

With our Dash Large Bore Electrohydraulic Subsea Safety Systems, we can provide industry-leading response times, isolating the well in as little as six seconds and disconnecting from the seabed in four seconds for a total emergency disconnect in 10 seconds.
