PIC - Hydrochloric Acid (HCI)
Hydrochloric acid (HCl) systems are integral for addressing calcium carbonate and inorganic scale deposits in well operations. These systems are highly customizable, allowing for manipulation of acid strength to suit specific downhole conditions and damage mechanisms. Their flexibility includes the capacity to control reaction timing, buffer against precipitate formation, and optimize acid placement downhole through weight adjustments. Additives are employed to enhance performance and precision, ensuring that the acid treatments specifically target inhibitive damage without additional well stress. A combination of HCl and hydrofluoric acid (HF) proves efficient in siliceous mineral dissolution. The formulation maintains a low pH to prevent harmful byproducts typical of HF reactions. Organic acid systems are available for sensitive or high-temperature wells, offering a safer alternative with significant scale removal potential. Augmentations in organic systems afford even greater efficiency in hostile conditions, retaining the same customization and enhancement as their mineral acid counterparts.
Hydrochloric acid is most commonly used for its strong dissolving power of calcium carbonate and other water formed or inorganic scales. Our conventional HCl acid systems are customizable depending on the conditions and damage mechanisms present downhole. The systems are augmented to manipulate acid strength, formulated to control the time required for spending, buffered to prevent precipitate formation, weighted to provide the best placement of the system downhole, and can be supplemented with a variety of additives.
Acid system additives allow for higher performance in damage removal and better control of the treatment system. More control of the acid reaction will ensure treatments are only targeting the damaging mechanisms prohibiting the well from performing at its optimum rate. These low cost, low risk, targeted solutions ensure the acid systems are not inducing any further damage to the well.
