A casing string that is run below the previous casing string but does not extend to the wellhead is called a __________.

🔍 Key Concepts

• Casing string vs production string – how each is used in a well • What it means for casing to be hung off or supported below the wellhead • The special name for a casing section that is suspended inside another casing and does not reach the surface

💭 Think About

• Ask yourself: which option refers to a type of casing that is attached inside a previous casing string and stops short of the wellhead? • Which choices are clearly something else (a downhole sealing tool, a full-length production tubing, or a non-standard term)? • Think about how drillers isolate deeper zones when they don’t want to run a full casing string all the way back to the wellhead.

✅ Before You Answer

• Eliminate any option that is not a type of casing string • Identify which term is commonly defined as casing that is suspended from another casing string and does not extend to the wellhead • Make sure the term you pick is used specifically for partial-length casing rather than tubing or tools placed inside the casing
