HCR 7000

General information:

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.
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.


Features and benefits

  • Non-corrosive to skin tissue (concentrate) (3rd party testing).
  • Ultra-low long term corrosion effects.
  • Clear; Ultra-low-fuming / vapor pressure.
  • Aggressive reaction rates vs typical modified or synthetic acid systems for spearheads, stimulations and
