We’ll work with you to design, build and operate a world-class on-site air separation plant to provide you with reliable, low-cost nitrogen exactly where you need it. We’re currently demonstrating this value in Hawkins, Texas where we supply ExxonMobil with more than 3,000 tons of N2 per day and in Samaria, Mexico where we supply Pemex with 6,680 tons of N2 per day. Cost-effective, versatile and field-proven, our nitrogen supply and injection systems are the preferred choice to help you increase extraction through enhanced oil recovery.

EOR Pilot and Injectivity Tests

Praxair also offers nitrogen and carbon dioxide service solutions for EOR pilot and reservoir injectivity tests — the outcome of which will help to determine how well your reservoir will respond to EOR. With the most extensive supply and service capabilities in North America, Praxair is well positioned to provide you with an economic and reliable supply of nitrogen and carbon dioxide. Furthermore, we have the technical expertise to help design the tests, field operators and equipment needed for optimal outcomes. We recently conducted tests with Hilcorp in Texas, injecting 180 tons of CO2 over three days to assess the EOR potential.
