Introduction to Casing & Tubing Design

This introductory level course explains the fundamentals of casing design. It describes the function of casing and tubing strings and the data needed for a design. It provides a consistent and systematic approach to casing design and covers the applications and limitations of the methods and formulas used.

Introduction to Casing and Tubing Design (ICD) is a course designed for those who want to understand the fundamentals of tubular design. ICD is focused on working stress design, giving participants an in-depth understanding of tubular strength, in addition to illustrating how well construction activities and well operations affect casing and tubing. As a suggested prerequisite to Advanced Casing Design (ACD), ICD introduces some of the advanced design methods discussed in ACD.

The objective of the ICD course is to provide engineers with a fundamental grounding in the mechanics of tubulars as applied to casing and tubing design. Some of the key areas covered in the course include:

The purpose of casing and required casing properties.
Working Stress Design (WSD) and Reliability Based Design (RBD) for casing and tubing.
Strength theories including the ISO TR 10400 and API 5C3 limit states.
Design and selection of connections, with emphasis on ISO 13679 approach to connection limits.
Materials selection and fracture mechanics-based criteria for sour design (including ISO TR 10400 sour limits).
Overview of some special problems encountered in casing and tubing design, including buckling, thermal effects, annular pressure build-up, wellhead movement, casing wear, conductor design, designing with expandables, worn casing strength, thermal cyclic service, etc.
Hand calculation and visualization of design loads and strengths, in order to appreciate the physics of the design process.
Numerous examples are used to illustrate the design process.

At the end of the course, engineers should be very familiar with the principles and practice of casing and tubing design, and be able to apply them in their work.

ICD stresses the need for computer-aided design, employing StrinGnosis® Online to this end.

StrinGnosis is an advanced tubular mechanics and wellbore heat transfer program. It is also the only program in the market capable of advanced design methods, such as Limit State Design, Reliability-Based Design, Brittle Failure Design, and anisotropic materials design – topics covered throughout the course.

Students are given full access to StrinGnosis Online for the duration of the training course and for two weeks after training has concluded.

ICD is offered in two formats; as a 5-day classroom-based course, and as an online course. The online course is taught over a two-week period, consists of nine live lectures approximately 2 hours each, supplemented with self-directed study and homework assignments. The online course schedule can be customized to meet any desired instruction schedule.
