Lex – Turbox Gaslift System

Turbox Gaslift System

To solve the production problems in wells with the lack of reservoir energy after the gas-lift operation, we have developed the Turbox gas lift pump. The system creates deep drawdown and avoids electricity use in the well by replacing the electric motor with a gas turbine in combination with the innovative Lex Ultra-High-Speed centrifugal pump operating at speeds up to 15,000 rpm.

Advantages

Overview

Over time, while intensive field development, the operating conditions become harsh expectedly: wells get water-flooded, reservoir and bottom-hole pressures may decrease if there is no reservoir pressure maintenance system, or it is ineffective. These complications cause the gas-lift wells’ production slowdown.

To address these issues wells, Lex engineers developed the Turbox gaslift pump. The system uses the existing gas-lift infrastructure: a compressor injecting oil or natural hydrocarbon gas.

Turbox Gaslift System is an upgraded gaslift technology, a combination of Ultra-High-Speed ESP and gas turbine instead of a motor. Gas is injected into annulus, entering the gas turbine’s stages, creating torque on its shaft and driving a centrifugal pump. Gaslift valve on top of the completion is optional but required on case-by-case equipment selection. Rigless deployment is available either with slick line or coil tubing.

Turbox avoids electric power in the well and gains production due to Lex UHS ESPTM with an operating speed up to 15,000 rpm. The technology also holds the required drawdown against the minimum gas injection pressure.
