Linde and Nissan Chemical to feature next-generation "Huff 'n Puff" technology to revive wells
RECHARGE HNP™ enhanced recovery solution offers quick payback for oil and gas wells

BRIDGEWATER, N.J., July 23, 2018 /PRNewswire/ -- RECHARGE HNP™, a new, energized "Huff 'n Puff" (HNP) technology that has improved oil and gas production by up to 500 percent, will be featured by Linde LLC and Nissan Chemical at URTeC in Houston, July 23-25, at booth #2018.

The RECHARGE HNP solution combines the demonstrated enhanced recovery powers of both gas and nanoparticles to create a synergistic, multi-spectrum treatment. Carbon dioxide (CO2) or nitrogen (N2) is used to drive nanoActiv® HRT (Hydrocarbon Recovery Technology) nanoparticles from Nissan Chemical further into the formation and enables them to penetrate deeper into capillary fractures and micropores of the rock, releasing additional hydrocarbons.

"One of the key features of the RECHARGE HNP solution is the simplicity in executing the treatment, with which operators have been very pleased," said Kevin Watts, senior application engineer, Global Market Segment Oil & Gas. "We believe this technology will have an important impact for oil and gas producers worldwide."

This synergistic gas-energized treatment can simultaneously address multiple production issues for conventional or unconventional natural gas or oil wells, and stimulate flowback to the wellbore for almost any type of rock formation.

After using the RECHARGE HNP solution on depleted wells in Texas for 180 days, production improvements in barrel-of-oil equivalents (BOE) ranged from 12 percent to 564 percent. Successful treatments have a quick 60- to 90-day payback.

Linde has provided HNP technology for decades and now applies that expertise to RECHARGE HNP treatments.

"Together with Nissan Chemical, we analyze the many permutations of the well and formation to screen, diagnose and prescribe the most effective combination of gas and nanoActiv HRT particles to optimize the treatment's yield," said Robin Watts, Chemistry & Energy program manager at Linde and a Houston-based member of Linde's Oil and Gas Services team.

Will Smith, president of Nissan Chemical America Corporation in Houston, added, "With the RECHARGE HNP treatment, our nanoActiv HRT particles can go further into the micro-fracture network of any product on the market today. Working with Linde, we can now help more operators resolve hidden production issues and really turn on the spigot."

Linde, a global leader in industrial gases and engineering, offers more than 50 years of experience in the energy industry. Linde is the biggest CO2 supplier for the industry in North America. Expertise spans CO2 and N2 treatments for fracturing, enhanced oil recovery and single-well stimulation (HNP).
