This Advanced Casing Design training course explores the essential concepts needed to understand the structural mechanics of downhole tubulars. Topics such as material properties, connection selection, performance characteristics, load cases, design factors, and buckling are among the key areas covered.
The Advanced Casing Design training course is structured to focus on the fundamentals, guiding delegates through the critical aspects of casing design for exploration, appraisal, and development wells, along with their associated risks, challenges, and solutions. It delves into manufacturing techniques, specifications, loading, design, and the challenges related to casing strings. Participants will gain a comprehensive understanding of casing techniques and the intricacies of casing strings.
This Energy training course also provides in-depth explanations and practical examples on all facets of oilfield tubular design. It covers both uniform and non-uniform loading, considering combination loading and outlining design procedures. Special attention is given to designing tubulars for corrosive environments, a new addition to the curriculum.
Participants will learn how to design casing systems for any type of well, including onshore, offshore, high-pressure and high-temperature wells, as well as horizontal and multilateral wells.
This Advanced Casing Design training course will cover:
- Key functions, characteristics, and various types of casing
