Casing design is an important task in oil and gas well design. Casing design involves evaluation of the factors that con tribute to the failure of the casing and proper se lection of the most suitable casing grades and weights that are both safe and economical for a specific job operation. A good knowledge of stress calculation is very essential in casing design. During casing design, various modes of casing failure must be identified and carefully handled such that the selected casing within a well segment is able to withstand all the failure modes. A safety margin, (also known as factor of safety) is always provided in casing de sign to allow for the future variations in the casing strength, loading and other unknown forces which may be encountered. This paper provides key information, education, relevant and technical details on casing design for oil and gas well.
