What is the procedure of recovering lost or stuck equipment in the wellbore called?

• A. Bailing
• B. Fishing
• C. Circulating
• D. Snubbing

Answer: (B)

The concept being tested is the term for retrieving misplaced or stuck equipment from a wellbore. That procedure is known as fishing. It involves using a fishing string and specialized tools to grab or engage the downhole object—like a tool, bit, or part of the drill string—and then applying controlled weight and pulling tension to bring it back to surface. The idea is to snag the fish so that it can be retrieved from the hole, often after careful positioning and sometimes circulating to help set up a grip or to clear debris. Other options describe different well operations. Bailing means removing liquids or loose solids from the well, not recovering a tool. Circulating involves moving fluid through the well to clean it or reposition debris, which can aid operations but isn’t the specific retrieval method. Snubbing is a separate technique used to run or retrieve equipment in a live (pressurized) well, rather than the general act of recovering lost equipment.
