  • Viscosity Hydrochloric Acid: 3. Acidizing Limestones

    Jan 03, 2016 · Hydrofluoric acid concentrations above 4.0% should not be used. As can be seen in Figure 6 above, the 15.0% HCl to 7.0% HF mixture, deteriorates the core causing a decrease in permeability. The use of high concentrations of hydrofluoric acid cause sand formations to become unconsolidated, and can create problems by promoting the production of sand.
