ElEVATORS

Basic functions and purpose of elevators:

Gripping and holding pipe during lifting and lowering operations.

• Provides reliable fixation of drill, casing and tubing pipes during their movement.

Safety during tripping operations.

• Minimizes the risk of pipe falling out and increases the efficiency of the drilling team.

Facilitates pipe installation and removal.

• Accelerates the process of connecting and disconnecting pipe during well construction and workover operations.

Compatible with different types of pipe.

• The design of elevators allows to work with pipes of different diameters and types of threaded connections.

Types of elevators:

• Pipe elevators (ET) - designed to work with casing and tubing.
• Hinged elevators (HLE) - used for convenient gripping and holding of pipes with lateral opening.
• Side elevators (SE) - provide side loading of pipes, which is convenient under certain working conditions.
• Universal elevators - used for different types of pipe and downhole operations.

Where are elevators used in the oil and gas industry?

• When drilling wells - to hold drill pipes during running and lifting.
• During well workover - for tubing retrieval and replacement.
• During well casing - for running and securing casing.
• During well operation - for replacement of production string and other operations.

Advantages of using elevators:

• High reliability and safety when working with pipes.
• Acceleration of running and lifting operations.
• Compatibility with various pipe sizes.
• Easy operation and maintenance.
