- Breaking out and setting back the kelly
- Attaching elevators to the elevator links
- Latching elevators to pipe
- Working on the monkeyboard
- Breaking out pipe
- Maneuvering pipe to racking area
Tripping In
- Elevators raised
- Tripping In -- latching elevators to top of stand
- Moving pipe to rotary
- Pipe is made up
- Slips are pulled
- Slips are set
- Elevators are unlatched
- Process repeated for all stands
- Pickup kelly and attach to drill string
- Break circulation, and
- Resume drilling
We will primarily cover the steps for "tripping out" in the last section, we'll discuss latching elevators to the top of stand during the tripping in process.
