Day 1:

• Prelim design refresher, Design Approaches like Deterministic (WSD), Probabilistic, Reliability, Survival Design Concept
• Pre-assessment test
• Well Architecture, Well Integrity, Basis of Design, Initial Conditions (Producers and Injectors), Worst-case discharge loads
• Load Cases – Casing and Tubing
• Installation Loads, Drilling Loads, Production/Injection Loads, Drilling and Production Thermal loads

• WellCAT Exercises – Drill and Prod Module

Day 3:

• Temperature Considerations
• Load Cases, Pipe Strength, Material Selection, Movement, Buckling, APB
• Material Selection, Metallurgy Fundamentals, Corrosion mechanisms, Sour service grade selection
• Fracture failure (brittle burst analysis), Quality Assurance and Quality Control
• Tubing Design, Difference between casing and tubing design criteria, Completion equipment selection
• WellCAT Exercises – Casing and Tube Module

Day 4:

• Connections: Types, applications, limitations
• Connection assessment levels (CAL), Testing and qualification, use of qualified envelopes in casing and tubing design (Connection tri-axial design)
• Casing Wear proposed workflow, wear prediction workflow, wear factors, key factors impacting casing wear
• WellCAT Exercises – Design with connection envelope, Casing Wear Analysis

Day 5:

• Kick Tolerance
• Survival design considerations, WCD, WCD loads (Cap and contain, Hot Collapse)
• Multi-String Analysis incl. WHG, APB, System fixity considerations
• Special problems, Expandable Tubular, Steam Cycling – issues like plastic strain, Bauschinger effect, low cycle fatigue, Subsidence/Compaction loads
• WellCAT Exercises – Multi String Module AFE and WHG
• Post Assessment, Feedback and certificates

Participants will need to have a solid foundation within well engineering principles and well design at a senior level. Experience with WellCAT software is important as each participant will work extensively with the software throughout the course to compliment the theoretical sessions.
