Frequently Asked Questions

Why does 15% and 28% HCl dominate oilfield treatments?

15% HCl is the industry standard balance between high dissolving power and manageable tubular corrosion. 28% HCl ("regular strength" in high-temperature or deep gas wells) halves the required pumping volume for the same rock removal, but requires expensive corrosion inhibitor intensifiers.

What happens to the CO2 generated by the acid reaction?

Under deep reservoir pressures (>1,000 psi), the generated carbon dioxide remains completely dissolved in the spent acid brine or forms a supercritical phase, lowering spent fluid viscosity and providing natural gas-drive energization during well flowback.
