Advanced Casing Design

Introduction

The course emphasizes the practical application of casing design principles and theory from a basic level through to advance. It can be tailored for either level. It examines the nomenclature of casing design, the manufacturing processes, materials and properties, the theory of burst, collapse and axial loadings, design policies and procedures, API specifications with review of the theory behind these and their limitations, connections and special cases such as HP/HT and sour service. The course examines the non-API principles of tri-axial design and how this improves upon the limitations of API.Kick tolerance and its impact on casing seat selection is considered in detail along with the processes of documentation and audit. Substantial emphasis is placed on worked examples beginning with basic practical problems and culminating in a full casing design for a typical well. This is approached from first principles and demands extensive use of mathematics.

Objectives

      A full appreciation of the key API Specifications, their origin and their limitations to modern casing design

    • Performance properties – definitions
    • Casing manufacturing processes, material selection and properties
    • Special requirements including HPHT and sour service
    • Stress / strain theory and the application to thick-walled cylinders
    • The objectives of casing design and the fundamental design principles
    • Casing connections
    • Mechanical design and design safety factors - burst, collapse and axial loading and integrated tri-axial stress analysis
    • Casing seat selection and the importance of kick tolerance
    • Pressure testing
    • Documentation and audit of the casing design process
    • Commercial principles of casing procurement and their impact on casing design
    • Casing design examples and practice

Training Methodology

The training methodology is interactive with group exercises and is suitable for all employees involved in functions management. The pace and level of the training workshop is customized to the understanding of the delegates. Ongoing back-up and support is available after the training on request to the supplier, and the training course is also available for in-house presentation as well as for “Competency Transfer”.

Who Should Attend?

Drilling and completion engineers 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
