In deep water, seabed temperature is close to freezing and the distance from well to host may be tens of kilometres. Fluid arriving at the host has cooled a long way, and any shutdown starts a race between restart and hydrate formation. Insulation, chemical injection, boosting and blowdown capability all exist to manage that, and each adds cost and complexity.

Well count is low and cost per well is extremely high, so deepwater wells are designed for high rates and long life. That means large tubing, high specification completions, sand control where needed, downhole monitoring as standard and, frequently, intelligent completions with zonal control, because the alternative of intervening later may cost more than the well produces in a year.

Subsea boosting and processing have changed what is possible. Multiphase pumps on the seabed reduce back-pressure on the wells and extend tieback distance; subsea separation removes water before it is lifted; subsea gas compression maintains gas production late in field life. These are expensive and add subsea reliability risk, so the trade-off between recovery gain and complexity is the central deepwater development question. This course covers the engineering and that judgement.

By the end of this training, participants will be able to:

• Describe deepwater field development concepts and host facility options.
• Evaluate subsea tieback architecture and its limits.
• Describe deepwater well and completion design requirements.
• Specify subsea equipment for deepwater pressure and temperature conditions.
• Describe riser systems, mooring and station keeping.
• Evaluate subsea boosting, separation and compression options.
• Design flow assurance strategies for cold deepwater systems.
• Plan deepwater production operations and monitoring.
• Plan intervention within deepwater access and cost constraints.
• Evaluate the economics that drive deepwater development and operating decisions.

Organisations sending participants to this training will:

• Build a common understanding of deepwater systems across technical teams.
• Improve development decisions on architecture, boosting and completions.
• Improve flow assurance design and operating procedures for long tiebacks.
• Plan interventions realistically against deepwater cost and access constraints.
• Support better evaluation of deepwater project economics.

Participants will:

• Understand how deepwater production systems are configured and why.
• Understand deepwater well, completion and subsea equipment requirements.
• Be able to evaluate boosting and subsea processing options.
• Understand flow assurance in cold, long tieback systems.
• Understand the cost drivers behind deepwater decisions.

• Production engineers in offshore and deepwater assets
• Subsea and facilities engineers
• Completion and well engineering staff
• Flow assurance engineers
• Field development and project engineers
• Asset and planning engineers

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
