Drilling || Casing Design
Here you can learn about the Casing Design
Course Description
This course covers casing design. It introduces design principles applicable to a wide range of environments, from simple to challenging conditions. The course explores casing nomenclature, manufacturing processes, materials, and their properties. Key topics include the theory of burst, collapse, and axial loading, as well as design policies and procedures. A comprehensive review of RigZone specifications is provided, along with an examination of the theory behind these standards and their limitations. Special cases such as HPHT (High Pressure, High Temperature) and sour service are discussed in detail. The course includes practical exercises, with some self-paced activities (homework) outside of the scheduled sessions. Participants should bring a personal calculator and have access to a computer with spreadsheet software, as well as familiarity with entering formulas.
Audience
This course is designed for well design engineers and those with a specific interest in critical well design.
Prerequisites
Basic knowledge of well design principles and engineering concepts is recommended.
