Who should attend
This course is intended for drilling and completion engineers, well engineers, petroleum, operations and production personnel and service company personnel with a basic knowledge of well design principles through to experienced drilling engineers who desire a more theoretical, detailed knowledge of the subject.
About the course
This five-day course covers the relevant subjects required to understand the structural mechanics of downhole tubulars. Material aspects, connection selection, performance properties, load cases, design factors, and buckling are just a few of the many topics that are covered. The course is designed to concentrate on the fundamentals, and on the last day, a 3 hour open book casing and tubing design exercise, aimed at consolidating and re-enforcing the principles and design techniques that have been covered during the week is carried out.
Upon successful completion of this course, the delegates will be able to:
- Understand the structural mechanics of downhole tubulars
- Understand material aspects, connection selection, performance properties, load cases, design factors, and buckling
- Apply casing and tubing design techniques
- Hand calculation
- Learn design Considerations ## Course Outline Day 1
Introduction to Casing and Tubing Design
Method Basic Concepts-Purpose of Tubular Strings - In this section the fundamental concepts of casing and tubing design are presented. These elements provide the foundation for the remainder of the course.
Design Requirements Material Aspects - This section takes an in depth look at the material aspects of design. Basic material science concepts are followed by a detailed look at API 5CT, 5B, and ISO15156.
Pipe Designation - Size, Weight, Tolerances
Sour Service Day 2
Connections - The components of a connection and connection selection techniques are thoroughly discussed. Upon completion, participants should be able to select an appropriate API or proprietary connection.
Proprietary Performance Properties - Rating calculation methods for each of the five design factors are presented in this section. API 5C3 is discussed in detail.
Internal Yield Pressure
Yield Strength and Threshold Stress Fundamental Design Principles - Load calculation methods for each of the five design factors are presented in this section. A significant amount of the lecture is devoted to the correct method for calculating axial load. Buckling calculations are simple once the participants have mastered the above.
Conventional and Service Life Design Methods
Triaxial w/ Class Exercise
Buoyancy and Buoyancy Factors
Free Body Diagrams w/ Class Exercise
Theory of tubular buckling w/ Class Exercise Day 3
Casing Loading and Design Considerations - Load cases from various operators are presented and the importance of Load Case rationalization is discussed.
- Tubular Selection
- Service Load Cases Day 4
Hand Calculation: A comprehensive casing design hand calculation summarizes the methods presented in the course.
Service Life Design Load(s) Equations a) Calculation Procedures b) Summary of Equations
