Casing design is an integral part of a drilling engineer's work scope. This course provides comprehensive overview of the design process emphasizing the working stress approach currently used in the industry. On completion of this course, successful participants will be to select casing points, identify tubular requirements and loads, and design and specify the required casing string. Through a combination of lecture and extensive hands on examples, the fundamentals of casing design are imparted to the attendees. Estimation of standard and special loads is covered in details. Standard theories of strength and failure are discussed as well as advanced considerations for combined loads. In addition safe handling, running and hanging practices are covered.
Drilling engineers, service personnel involved in developing well plans, and managers interested in learning about the well design process.
You Will Learn How To
- Select casing setting depths based on pore and fracture pressure data as well as other criteria
