Petropedia explains Calcium Carbonate
In the oil and gas industry calcium carbonate is used as a formation-bridging agent that is added to drilling mud so as to intensify the density of the mud in oilfield drilling applications. It increases the mud density to about 1.44 kg per cubic meter or 12 lbm/gal. This chemical compound is easily dissolved in hydrochloric acid and can be used to clean up the production zones. It is used primarily as a bridging material in drill-in, completion and workover operations of an oil or a gas well. Calcium Carbonate is also helpful in controlling the fluid loss in brines when used along with the polymers.
In the construction industry calcium carbonate is used as a raw substance for building materials and as an ingredient for cement.
