Subsea & Deepwater Completions
This course covers subsea and deepwater completion design and installation. Participants study completion architecture, tubing hanger and tree systems, horizontal and vertical trees, downhole equipment selection, control systems and umbilicals, installation and running procedures, well clean-up and start-up, intervention access, integrity requirements and the cost drivers of subsea completions.
Description
Subsea completions are installed from a floating vessel onto a wellhead on the seabed, with the tree, controls and downhole equipment forming part of a system that cannot be accessed without a vessel. The engineering is driven by reliability, intervention cost and the long tiebacks that separate the well from the host facility.
This course covers design and installation. It starts with subsea completion architecture and the choice between horizontal and vertical trees and its consequences, then covers tubing hanger systems, orientation, control line penetrators and downhole equipment selection for subsea service. It covers control systems, umbilicals, chemical injection and downhole monitoring, and the installation sequence: running the completion from a floating vessel, landing and orienting the hanger, installing the tree and commissioning. The course then covers well clean-up and start-up through long tiebacks, intervention access and its cost, integrity and barrier requirements for subsea wells, and the cost drivers that shape subsea completion decisions.
The tree choice shapes everything. A horizontal tree places the tubing hanger in the tree body, so the completion can be pulled without removing the tree, which suits wells expecting intervention; a vertical tree places the hanger in the wellhead, so the tree can be recovered independently. The decision affects installation sequence, intervention cost and barrier arrangements for the life of the well.
Reliability is worth more than it costs. Any failure in a subsea completion requires a vessel, and the cost of mobilising one usually exceeds the cost of the equipment many times over. That justifies redundancy, higher specification components and more testing than an equivalent land well would receive.
Clean-up and start-up through a long tieback is a flow assurance operation. Completion fluid must be displaced through kilometres of cold flowline, hydrate prevention must be maintained throughout, and the well must be brought on in a controlled way. Planning that sequence is part of the completion design rather than an operations problem to be solved later.
By the end of this training, participants will be able to:
- Select subsea completion architecture for the field and well requirements.
- Compare horizontal and vertical trees and their consequences.
- Specify tubing hanger systems, orientation and control line penetrators.
- Select downhole equipment for subsea service and reliability.
- Specify control systems, umbilicals and chemical injection requirements.
- Specify downhole monitoring and intelligent completion equipment.
- Plan completion running and installation from a floating vessel.
- Plan tree installation, testing and commissioning.
- Plan well clean-up and start-up through long tiebacks.
- Apply integrity and barrier requirements and assess subsea completion cost drivers.
The course is instructor-led. Subsea completion systems are covered with drawings, equipment specifications and installation procedures, and participants design completions and installation sequences for given subsea developments. Field cases cover installation problems and completion failures requiring intervention. Participants are encouraged to bring their own projects for discussion.
Organisations sending participants to this training will:
- Design subsea completions for reliability over their full life.
- Reduce intervention requirements and their cost.
- Improve installation planning and reduce vessel time.
- Plan clean-up and start-up through long tiebacks effectively.
- Meet integrity requirements for subsea wells.
