A completion is a compromise between production, cost, safety and future flexibility. A large tubing gives high early rates but may not lift fluid later in life. A simple cased and perforated completion is cheap but limits zone control. A monobore completion suits through-tubing intervention but constrains equipment. Every completion in the field is the result of choices like these, and the consequences last for decades.

Tubing design is the mechanical core of the work. Tubing must carry production loads, survive pressure testing, stimulation and shut-in, and absorb temperature-induced length and force changes without exceeding the strength of the pipe or the rating of the packer. Corrosion, erosion and sour service requirements drive material selection, and completions in high pressure or high temperature wells leave very little margin.

Common failures trace to a few causes: designs based on start-up conditions rather than field life, load cases that were never checked, elastomers and metallurgy unsuited to the produced fluids, damage caused by completion fluids and installation practice, and completions that leave no practical way to intervene. This course covers the design process that prevents them.

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

• Define the design basis for a completion from reservoir, production, safety and intervention requirements.
• Select a completion type and architecture for given well and reservoir conditions.
• Size production tubing for flow, and analyse tubing stresses for the full set of load cases.
• Select packers, anchors and their setting mechanisms.
• Specify flow control, safety valves, nipples and downhole monitoring equipment.
• Select wellhead and Christmas tree equipment and understand pressure rating and sealing.
• Compare perforated, open hole and sand control completion options.
• Specify completion fluids and practices that protect the formation.
• Plan completion installation, testing and commissioning.
• Assess how completion decisions affect integrity, artificial lift and future intervention.

The course is instructor-led. The completion is built from the bottom up, component by component, with worked examples for tubing sizing and stress analysis and for equipment selection. Field cases show where completion designs have succeeded and failed and why. Participants are encouraged to bring their own well conditions and completion problems for discussion.

Organisations sending participants to this training will:

• Get completions designed for the full life of the well, not just for start-up.
• Reduce completion failures, leaks and premature workovers.
• Improve the consistency and documentation of completion design across the asset.
• Preserve future options for artificial lift, stimulation and intervention.
• Reduce formation damage caused during completion operations.

Participants will:

• Understand the function of every component in a production completion.
• Be able to produce and check a completion design.
• Be able to carry out tubing stress analysis for the main load cases.
• Understand how completion choices affect production and intervention over field life.
• Be prepared for advanced completion, sand control and intervention work.

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.
