Product Sheet Citric Acid
Reduce the pH of drilling fluids and remove calcium.
Reduce pH, precipitate soluble calcium, and sequester iron
Citric acid is used to reduce pH and remove calcium when drilling cement, to reduce the potential of crosslinking polymers (xanthan and others) from iron, and to prevent fish-eyes when mixing polymers. An organic acid, citric acid is less reactive compared with sulfuric or hydrochloric acid, thereby being somewhat safer to handle.
