🔍 Key Concepts

• Emergency hang-off procedures for drill pipe on a MODU • Relationship between drill bit position and risk of sticking or damage to well/casing • Effect of having the full drill string in tension vs. partly inside casing or open hole

💭 Think About

• Which option best reduces the chance of the drill string getting stuck if you lose circulation or motion control? • How does placing the bit relative to the last casing shoe affect the risk of formation collapse or differential sticking? • In a heavy weather or emergency situation, do you want the bit deep in open hole, inside casing, or close to bottom—and why?

✅ Before You Answer

• Compare the risks of having the bit deep in open hole versus inside or near the last casing shoe. • Think about what happens to the wellbore if the MODU moves or heaves while the drill string is hanging off. • Verify which position gives the most protection to the wellbore and the drill string while still allowing you to regain control later.
