Gas Lift Pump System

Turbox GasLift Pumps System

The Turbox GasLift Pumps System is an advanced artificial lift solution developed for oil, gas, and geothermal applications with declining reservoir energy and ineffective gas-lift performance. Using a gas-driven turbine combined with the Lex Ultra-High-Speed centrifugal pump instead of an electric motor, it delivers deep drawdown, stable operation across a wide operating range, and increased production while eliminating downhole electricity, reducing power-related failures, and ensuring reliable performance in harsh and high-temperature environments.

Advantages

To solve production problems in wells experiencing depletion of reservoir energy after the gas-lift operation and boost production from geothermal wells, Blue Earth Energy Inc. (a Lex company) has developed the Turbox Gaslift Pumps System. The system creates deep drawdown and avoids electricity use in the well by replacing the electric motor with a gas turbine. This works in combination with the innovative Lex Ultra-High-Speed centrifugal pump operating at speeds up to 15,000 rpm.

Maximum Drawdown

Provides maximum drawdown during gas-lift operation, improving production performance.

No Electrical Failure Risk

Eliminates the risk of electrical component failures in the system.

Harsh Condition Tolerance

Designed to operate reliably in harsh environments and unstable inflow conditions.

Field-Proven Technology

Tested and validated in real field operations for reliable performance.

Overview

Over time, with intensive field development, well conditions can deteriorate; there’s a risk of flooding and reservoir and bottom-hole pressures may decrease if there are no or ineffective reservoir pressure maintenance systems in place. These complications can lead to motor operation problems when running under part-load, such as overheating and breakdown.

To address these issues in gas-lift wells, Lex engineers developed the Turbox GasLift Pumps System. The system uses the existing gaslift infrastructure – a compressor injecting oil or natural hydrocarbon gas. The Turbox GasLift Pumps System is an upgraded and modernized gaslift that uses a combination of our UHS Pump and turbines instead of a motor. Gas is injected into annulus, entering the gas turbine’s stages, creating torque in its shaft and driving a centrifugal pump. Gas lift valves are optional and may be required when designing activation process on a case-by-case basis. Rigless deployment is available either with a slick line or coil tubing. Turbox Gaslift Pumps System technology avoids the use of electricity in the well, improves pumping efficiency and gains production with Lex UHS Pump with an operating speed up to 15,000 rpm. The technology also holds the required drawdown against the minimum gas injection pressure.
