Project Objectives

The primary objective of this project is to provide the basis for detailed design of a cost‐effective deepwater Coil Tubing (CT) system for downhole work in deep water Gulf of Mexico (GOM) satellite wells without need for a Mobile Offshore Drilling Unit (MODU). This work will facilitate improved resource recovery from existing satellite wells and make it practical to develop reservoirs that would otherwise not meet economic hurdles. Tasks and deliverables include specification of equipment, identification and assessment of hazards and failure modes, and a comprehensive report including a plan and design basis for detailed design in Phase 2.
