Elevators are not used in drilling and well completion operations.

Elevators are primarily used in construction, allowing people and materials to move vertically between floors in buildings.

In drilling and well completion, the equipment used to lift and lower the drill string and casing is called a drawworks. This is a powerful winch system that provides the necessary force to handle the heavy loads involved in drilling and well completion.

Here are some of the key tools used for lifting and lowering in drilling and well completion:

• Drawworks: The main winch system that provides the power for lifting and lowering the drill string and casing.
• Drilling Line: A strong steel cable that connects the drawworks to the drill string or casing.
• Crown Block: A pulley system at the top of the derrick that guides the drilling line and increases the lifting capacity of the drawworks.
• Traveling Block: A movable pulley system that attaches to the drill string or casing and moves up and down the derrick.
• Hook: A large hook that attaches to the traveling block and connects to the drill string or casing.

These tools work together to safely and efficiently lift and lower the equipment needed for drilling and well completion.
