Carbonate Acidizing

Halliburton’s Carbonate Acidizing Portfolio helps simplify the fluid selection process by providing versatile acid systems that are specially designed for most conditions encountered in carbonate formations throughout the world, helping leave the formation conductive farther from the wellbore, for a longer productive well life.

Combined with design and placement, these acid systems are proven effective in even the most complex of fracture and matrix acidizing treatments.

Carbonate Completion Acid - A unique acid blend that is effective even on the most difficult oils of the world (sludging, asphaltenic oils).

Carbonate Emulsion Acid - An emulsified acid system with superior wormholing characteristics.

Carbonate Stimulation Acid - A viscous acid system for improved fluid-loss control and deeper penetration of live acid.

AeroBoost - A stable-foamed acid system that optimizes acid stimulation treatments in the depleted formation and/or challenging completions. The foamed acid system provides enhanced diversion properties (up to 80% foam quality). 

Hot Rock Acid - High temperature, low-corrosion acid system. An organic acid system with a dissolving power equal to 15% HCl at different ratios to eliminate secondary precipitation problems and maintain maximum dissolving power.

KelaStim Plus - A chelant-based acid system for stimulating high-temperature carbonate or mixed carbonate/sandstone formations. It provides less risk of rock deconsolidation compared to high-strength HCl acid fluids and lowest corrosion characteristics of all acid stimulation blends.

PAD Acid - The solvent in PAD acid dissolves organic residues while the acid removes acid-soluble scale deposits or reacts with the formation to help increase permeability.

Zonal Coverage Acid - For optimum acid distribution in long pay intervals. The system is pumped as a gelled hydrochloric acid that crosslinks from acid spending giving a higher viscosity which reduces leak off and improves zonal coverage.

Zonal Coverage Acid  II - A non-polymeric acid gelling agent used to self-diverting acid treatments. While little viscosity is imparted to the live acid by this gelling agent, once the acid spends the viscosity rapidly increases, providing excellent diversion properties to optimize acid fluid placement.
