The term "Iron Roughneck" in the oil and gas industry refers to a powerful and versatile piece of equipment used in both drilling and well completion operations. It's essentially a pipe connection device that sits on the rig floor or is suspended just above it. Its unique design combines the functionality of lead and backup tongs with an integral spinning table, making it a true workhorse on the drilling rig.

Scenario: A drilling crew is preparing to run casing into the wellbore. They will be using an Iron Roughneck to connect the casing sections.
Task: Describe the steps involved in using an Iron Roughneck to connect two casing sections. Be sure to mention the roles of the lead and backup tongs, and the importance of the spinning table.
The steps for connecting two casing sections using an Iron Roughneck are: 1. **Prepare the Connection:** Align the two casing sections, ensuring the threads are clean and free from debris. 2. **Lead Tongs Engage:** The lead tongs grip the top joint of the casing, starting the connection process. 3. **Backup Tongs Engage:** The backup tongs grip the bottom joint, providing added security and preventing slippage during make-up. 4. **Spinning Table Activates:** The spinning table begins rotating the top joint, ensuring uniform thread engagement. 5. **Make-up to Full Connection:** The lead tongs continue to turn the top joint, gradually screwing it into the bottom joint, while the spinning table rotates to ensure even thread engagement. 6. **Final Tightening and Release:** Once the connection is fully made, the lead tongs provide a final tightening torque. The backup tongs are released, followed by the lead tongs, leaving the connected casing securely in place.
