Formula Reference

Acid Volume Calculation

V_acid = 7.48 x phi x h x (rt^2 - rw^2) x PV_factor Where: phi = Porosity (fraction) h = Net pay thickness (ft) rt = Treatment radius (ft) rw = Wellbore radius (ft) PV_factor = Pore volumes to treat (typically 1-3)

Sandstone Acidizing Guidelines

Stage 1: HCl Preflush (5-15% HCl) - Dissolve carbonates - 25-50 gal/ft Stage 2: Mud Acid (HCl/HF) - Clay and silicate removal - 50-100 gal/ft Stage 3: Overflush - NH4Cl or weak acid - 50-100 gal/ft
