 · This paper investigates the interaction between the barite chelate and the calcite formation after filter cake dissolution. The barite filter cake was formed over the face of calcite rock samples using a HighPressure High Temperature (HPHT) fluid loss apparatus. Chelating agent solution was then used to dissolve the filter cake.

Barytes (also known as Barite and Barites) is a form of Barium Sulphate, BaSO4. Pure Barytes is 66% BaO and 34% SO3, normally white but many deposits are discoloured by small amounts of impurities. Barytes is found throughout the world as an ore body in residual, vein type, as well as bedded forms.

 · It influences the precipitation kinetics and the solubility of barite by the formation of CaSO4° ion pairing as a predominant role of complex formation (CaSO4) and the increase of the ionic strength. In Ca(HCO3)2BaSO4NaCl aqueous system, experiments have showed that added or formed barite in the reaction media accelerates calcite precipitation.
