Enviro-Syn® HCR-7000™

Enviro-Syn® HCR-7000™ is part of the “Environmentally Responsible” Modified Acid™ product line that minimizes the hazardous exposure levels, corrosion rates and negative HS&E properties of HCl while maintaining the positive aspects of solubilizing ability and reactivity rates.

Available across North America from 11 manufacturing sites.


Enviro-Syn® HCR-7000™ is a powerful, low fuming Modified Acid™ that has similar solubilizing abilities of 15% HCl (concentrate) and can be enhanced through the addition of conventional oilfield chemistry.

HCR-7000 is a “high-performance” replacement for all hydrochloric acid blends and can be utilized and exposed to perforating tools and wire-line. These systems allow operators to pump acid with the perforating guns, reducing time per stage and saving considerable water per stage (hole-volume) where applicable. Major wire-line vendors approved.

Enviro-Syn HCR-7000™ can be utilized in acid spearhead applications, stimulations, workover, fracs at low to high temperatures where an aggressive removal of formation, skin damage, scale or mineral deposits is required and can safely be used in place of all HCl blends. With its ultra-long-term corrosion protection (up to 7 days at mid-range temperatures) it can be utilized for long term well displacement soaks/treatments or aggressive remedial applications.

Enviro-Syn HCR-7000™ is an “Industry Shifting” technology capable of covering your acid requirements while eliminating most all concerns of corrosion, HS&E, transportation/storage in wellbore environments up to 190°C / 375°F.


The Enviro-Syn HCR-7000™ Class One acid system has a more aggressive reaction rate than any Modified Acid™ on the market and will provide you with superior injection rate pressure reductions at times very comparable to 15% HCl without the HS&E hazards, compatibility issues, storage/transport challenges or the aggressive corrosion rates at a competitive price point.

Hydrochloric Acid (and its fumes) has a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines irreversibly
