Based on decades of experience, Linde is uniquely positioned to work on a worldwide scale with oil and gas producers and oilfield service companies to support fracturing, well stimulation, enhanced oil recovery (EOR) and improved oil recovery (IOR).
Supplying carbon dioxide (CO2) and nitrogen (N2) to oilfields since 1979, we serve most of the major basins in the world. Our expert teams are specialised in EOR, fracturing and Huff and Puff applications. Supporting everything from reservoir screening to project execution, we’ve got you covered.
Energised fracturing – maximising yield, minimising produce water
CO2 fracturing is one of the cleanest and most effective approaches available today to increase oil and gas production. It is even suited to unconventional sources like shale, tight sand formations and coalbed methane. N2 is an effective alternative to CO2 in many situations, especially for fracturing shallower wells.
Injected into gas and oil wells, energised solutions enhance hydrocarbon production rates and yields. Fracturing treatments energised with CO2 or N2 maximise long-term production, minimise formation damage, reduce water usage and lower overall costs.
Nitrogen and carbon dioxide play a central role in EOR. With this procedure, N2 or CO2 is pumped underground at high pressure. The gas injected increases the pressure in underperforming oil wells so that fossil resources can be recovered more easily. This significantly improves yields. The world's largest EOR project using nitrogen, led by PEMEX, Mexico's largest oil company, relies on Linde as the primary nitrogen supplier.
Linde and Nissan Chemical have teamed up to bring a ground-breaking treatment to the market. RECHARGE HNP™ offers the best results at an affordable price. It is perfect for operators looking for a simple, flexible and low-cost enhanced recovery solution with quick payback. RECHARGE HNP™ is a multi-spectrum, proprietary remediation treatment for wells with production problems. Combining properties of gas and nanoActiv® HRT nanoparticles creates a unique, synergistic treatment that addresses several potential production issues simultaneously. A successful treatment will enhance production six months or more. The flexibility of this treatment makes it applicable to all types of wells: conventional/unconventional and oil/gas.

Energised Huff and Puff (HnP) – increased yield with single well stimulation
Since the early 1990s, Linde has deployed HnP technology to inject CO2 into depleted wells to incrementally increase oil production. Less costly than refracturing, Huff and Puff provides the energy to give hydrocarbons in low-pressure zones the necessary lift to get them flowing to the wellbore. It is a proven single-well stimulation method for increasing production. Linde can help determine if this is the right technology for your oil wells, design the applicable treatment and operate the stimulation.
