This course provides an overview of the design process, emphasizing the working stress approach currently used in the industry. On completion of this course, successful candidates will be able to select casing points, identify tubular requirements and loads, design and specify the required casing string.

By the end of this course delegates will be able to:

• Select casing setting depths based on pore and fracture pressure data as well as other criteria
• Determine casing and bit sizes, and alternatives for contingencies and special clearance situations

• Identify and define load cases to meet specific design requirements
• Apply standardized design factors to meet specific design requirements and identify the controlling design load for each string in the well
• Use and understand casing and connection specifications and select casing to satisfy the controlling design requirements
• Understand the limits of single load specifications and adjust the basic design for combined loading effects
• Design casing for high pressure fracturing in horizontal wells
• Apply practical safe handling, running, and hanging
