Electric Submersible Pump

ESP with Jet Pump (Jet ESP)

The Lex ESP with Jet Pump (Jet ESP™) is an advanced artificial lift system developed to improve production in gassy oil and gas wells. By combining an Ultra-High-Speed ESP with a jet pump in a single completion string, it stabilizes pump operation, reduces bottom-hole pressure, and increases drawdown, delivering higher and more reliable production even in wells with high gas content, installed packers, or unstable surface conditions.

Stable operation in gassy conditions (GVF up to 75%)

Advantages

To improve production in gassy wells, we designed the ESP with a jet pump (Jet ESP). The Jet ESP stabilizes the pump operation and increases the drawdown by reducing the bottom hole pressure. A jet pump and UHS ESP™ are being installed in a single completion string and are very effective in wells with high GOR, installed packer or in case of surface check valve failure.

Increased Drawdown

Improves drawdown and production performance in gassy wells.

Reliable Design

No moving parts, providing high reliability and reduced risk of failure.

Compact Configuration

Compact system design enables installation through high-DLS well sections.

Harsh Environment Tolerance

Stable operation in wells with gas, solids, high temperatures, and corrosive fluids.

Wireline Installation

Allows easy wireline installation and retrieval of the pump from the well.

Overview

In gassy wells, gas often accumulates behind the annulus and increases the uplift pressure at the bottom. This can be caused by a faulty wellhead check valve, use of a packer or high line pressures at remote fields. As a result, the drawdown and well productivity reduces significantly.

Jet ESP artificial lift system combines Ultra-High-Speed ESP (UHS ESP™) and Jet Pump in a single completion string. The jet pump is in the well tubing above fluid level. Jet pump nozzle is hydraulically connected to ESP discharge through the well tubing, while jet pump intake is open to the well annulus. UHS ESP™ provides power fluid to the jet pump, causing a drop in pressure. Gas from the annulus then enters the mixing chamber, forming a mixture with the produced fluid, forcing the mixture straight up to the wellhead. The reduced annulus pressure provides the reduction of bottom-hole pressure and increases drawdown resulting in a production gain.
