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.  

Course Objectives

  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 

  • Objectives
  • 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.

  • Pipe Types

  • Loading Modes

  • Design Factors

  • Pipe Functions

  • 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 Mechanics

  • Pipe Designation - Size, Weight, Tolerances

  • Grade

  • Lengths

  • 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.

  • API
  • Proprietary    Performance Properties - Rating calculation methods for each of the five design factors are presented in this section. API 5C3 is discussed in detail.

  • Tension

  • Compression

  • Internal Yield Pressure

  • Collapse

  • 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

  • Burst

  • Collapse

  • Tension/Compression

  • 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
  • Cost
  • 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

  • Burst
  • Collapse
  • Axial Load (Tension/Compression)
  • Triaxial Equivalent Stress Intensity   Example String Designs (Hand Calculation, Class Exercise)

a) Production Casing    Specialist Design Considerations - a discussion of the more specialist aspects of casing design, for those that are interested:

  • Multi-String Mechanics and Wellhead Growth.
  • Wellhead Lock Device Force Demand
  • Annulus Pressure Build-Up, APB, theory and discussion.
  • Torque and Drag considerations for the running of casing, both flooded casing and extended reach (ERD) floated casing, theory and discussion.   Day 5

A 3 hour open book casing design exercise to consolidate and re-enforce the course principles and design techniques. RECAP
