An effective sandstone acid stimulation design must consider a tremendous amount of information. Halliburton's Sandstone acidizing portfolio uses a systematic approach to the complex process of optimizing sandstone acid treatments.
Silica Scale™ Acid System - Combines a high HF acid concentration to remove the silica scale from geothermal wells.
Sandstone Completion™ Acid System - It provides maximum dissolving power without secondary precipitation, prevents aluminum precipitation, and is one of the fluids of choice when mineralogy is unknown.
Fines Control™ Acid System - Retarded hydrofluoric acid fluid system that removes deep damage caused by fines and swelling clays and prevents fines migration.
K-Spar™ Acid - Compatible with formations high in potassium feldspars and illite and prevents fines migration.
Volcanic™ Acid II - Organic acid/HF acid system that is compatible with HCl acid-sensitive minerals and can be used in higher-temperature applications.
SandStim™ Service - A chelant-based fluid for stimulating sandstone or mixed sandstone/carbonate formations or formations with uncertain mineralogy. Capable of removing silica scale and formation fines damage, all with fewer risks of by-product precipitation, rock deconsolidation, and fines production.
