The four classic effects are simple individually and awkward together. Piston effect comes from pressure acting on cross-sectional area changes; ballooning from internal and external pressure straining the pipe; buckling from compression below the neutral point; and thermal effects from expansion and contraction, which are often the largest of the four. Their combination decides tubing movement, seal stroke requirement and the force applied to the packer.

Load cases are where design either holds or fails. A string that is comfortable during production may be overloaded during a stimulation with cold fluid, or during shut-in when the tubing heats and the pressure rises. The designer's job is to run every credible case, including the unlikely combinations, and check the worst against the ratings with proper design factors.

Building this in Excel produces a tool that shows exactly where the margin is thin. That is far more useful than a pass or fail from a program, because it shows which case governs, which effect dominates and what change would give the most margin. This course builds that tool step by step.

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

• Calculate tubular properties, ratings and temperature derating.
• Build pressure and temperature profiles for each operating case.
• Calculate piston effect forces and length changes.
• Calculate ballooning and reverse ballooning effects.
• Calculate buckling, neutral point and helical buckling length change.
• Calculate thermal expansion and contraction effects.
• Determine tubing movement and packer forces for different seal arrangements.
• Perform triaxial stress checks against the von Mises envelope.
• Calculate annular pressure build-up and evaluate mitigation.
• Build a load case matrix and identify the governing case for design.

Organisations sending participants to this training will:

• Design completions with verified margin across all load cases.
• Check vendor and software tubing stress results independently.
• Reduce completion failures caused by unanalysed load cases.
• Assess annular pressure build-up risk before it becomes a problem.
• Build in-house completion design capability.

Participants will:

• Understand tubing stress analysis in full detail.
• Be able to build and run a complete load case analysis.
• Be able to identify the governing case and the dominant effect.
• Be able to check and challenge completion designs from others.
• Leave with a working tubing stress analysis workbook.

• Completion engineers
• Production engineers
• Well engineering and drilling engineers
• Well integrity engineers
• Workover and intervention engineers
• Engineers reviewing completion designs

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.
