ESP Gas Devices

Maximize production in gassy well environments with reliable and efficient gas handling devices

Our gas-handling solutions for electrical submersible pump (ESP) operations include

  • Centrifugal devices for gassy wells with up to 45% gas volume fractions (GVF) at low intake pressures
  • Axial flow systems for ultrahigh-gas-cut wells with GVF up to 75%

Our Portfolio

VGSA

Vortex Gas Separator Assembly

The VGSA is designed to remove free gas from produced fluids before it reaches the ESP, preventing cycling, gas lock, and cavitation. By venting gas to the annulus, it delivers a stable motor load, extended run life, and higher production efficiency.

Unlike static separators that only redirect flow, the VGSA is a dynamic separator that uses vortex action to separate gas at higher flow rates. Its patented, abrasion-resistant design ensures reliable performance in challenging wells.

The VGSA is well-suited for gas-cut oil wells, annular gas production, gas-lift to ESP conversions, and dewatering operations, providing consistent separation across a wide operating range.

AGH

Advanced Gas Handling Device

Increase production in wells with up to 45% GVF

Improve the overall lift efficiency of a submersible lift installation with the advanced AGH gas-handling device, which maintains a higher gas/liquid ratio (GLR) in the tubing string. It is suitable for high-GOR, gassy wells with up to 45% gas volume fraction (GVF) at low intake pressures.

The system’s higher GVF reduces the hydraulic horsepower required to lift fluid to surface. The AGH device uses a unique centrifugal stage design to alter the pressure distribution of the impeller, creating a homogenized mixture with reduced gas bubble size. This conditioned fluid behaves as a single-phase fluid before entering the pump.

MGH

Multiphase Gas-Handling System

Increase production in reservoirs with high GOR

High-GOR, high-gas environments are now common electric submersible pump (ESP) applications, but to produce at full potential, main production pumps need the support of reliable gas handling technology.

The MGH multiphase gas-handling system is designed to manage this issue. The specially designed axial-flow stages of the MGH system provide a more efficient energy transfer than centrifugal stages, avoiding gas locking at high gas-volume fractions (GVFs). The system efficiently manages higher percentages of free gas in gassy wells and achieves much higher drawdowns in subsea wells and wells with non-vented packers, resulting in trouble-free operations and increased production from reservoirs.

MGH system pumps are available in many series options, with gas and liquid downhole flow rates from 800 to 47,000 bbl/d [127 to 7,472 m3/d].

  • Shaft diameter from 0.87 to 1.37 in [22.2 to 34.8 mm]
  • Heliocoaxial stage type
  • Self-lubricating, silicon carbide graphitized radial bearing material
