• Temperature effects, buckling analysis, and wear considerations.

4. Casing Setting Depths

• Selection criteria based on pore pressure, fracture gradient, and kick tolerance.
• Graphical methods for casing seat selection.

5. Design Procedures

• Design principles for exploration, development, horizontal, and high-pressure/high-temperature (HPHT) wells.
• Practical application of design factors to meet specific requirements.

6. Special Considerations
