Calcium Carbonate



Global Drilling Fluids and Chemicals Limited at its manufacturing Facility in Gujarat, India manufactures one of the most Popular Weighing Materials for the Oilfield Industry chemically Known as Calcium Carbonate.


Course /Medium/Fine

GLO CARB manufactured by GDFCL is acid soluble grinded Calcium Carbonate. It is used as a Bridging and a weighing agent used in drilling. It is used to increase mud density and is preferred to Barite as it is acid Soluble. It is grinded in three sizes Coarse, Medium and Fine

GLO CARB manufactured by GDFCL is essentially a Bridging and a weighing agent for controlling Fluid loss and Density. It can be used in both oil based and water based Fluid Systems. GLO CARB F is used essentially as a weighing agent where as GLO CARB C and GLO CARB M are used for bridging and seepage control
