Deep Water Gulf of Mexico – Challenging Hi Angle Subsea Gas Lift Valve Intervention

Presentation

This paper presents the technology utilized to efficiently replace a leaking Gas Lift Valve (GLV). The technical challenge was to replace the GLV, at short notice (due to the operating window), allow the Kickover Tool (KOT) to pass a minimum restriction of 3.313”, in a 65 degree well at 12,000ft with an “S” shaped profile.

• Enable two runs (retrieve / install) GLV, with no miss runs or NPT.
• Simplify the operational steps from pulling the original GLV, replacing wit the new GLV, testing the Completion, then bringing the well back into production.
• Reduced rig time, reduced safety risks, and accelerate well start-up process.
