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
