Description

product offering

• Injects high pressure gas down the wellbore

  to lighten liquid column and enhance recovery

• Only high flowrate lift system designed specifically for unconventionals

ESP

• Utilizes an electric motor to drive a multistage

centrifugal pump to lift production from the well

New Offering

Gas Lift

• Injects natural gas into the wellbore to reduce

  fluid column density and hydrostatic pressure

• Allows reservoir pressure to push fluids to the surface

Plunger Lift

• Utilizes downhole plunger to lift liquids from

low-pressure or high gas production wells

Rod Lift

• A reciprocating rod (sucker rod) driven from

  surface activates a downhole pump

• Downhole pump pushes liquids to surface

HPGL Key Highlights

Wellbore

Injection

• Natural gas is injected down the wellbore via the production tubing or

annulus

Increased

Production

• Discharge pressure (up to 5,500 psi) lightens the liquid column, reducing

bottom hole pressure and promoting high production rates

Illustrative HPGL Application

High injection pressure (5,500 PSI)

30%+

Annual cost savings vs. ESPs

Bottom hole pressure lower than max injection pressure

Injected gas lifts liquids to surface

• The total count of tanks with VRU systems has more than doubled from 2015 to 2022, growing from ~13,000 to ~31,000 at facilities reporting their emissions to the EPA

• VRU adoption, although still at a relatively low penetration level, has been on an upward trajectory since 2020 as more facilities have opted to incorporate vapor recovery

• VRU adoption is growing rapidly in the Permian with adoption up to 42% in the Midland and 37% in the Delaware in 2022 among facilities required to disclose to the EPA GHGRP program

Source: Rystad Energy (January 2026 and August 2024)

1) Large oil and gas facilities with annual emissions over 25,000 TCO2e have been mandated to report emissions and emissions-related data to the EPA since 2011 under the Greenhouse Gas Reporting Program (GHGRP). In 2014, the data collection requirements were expanded for Subpart W, requiring GHGRP reporting oil and gas facilities to report data on their vapor recovery technology starting in 2015
