PRODUCT DESCRIPTION NC-CARB F is an acid-soluble weighting material designed to increase the density of drilling and workover completion fluids. It has a specific gravity of approximately 2.8 and can be used to formulate fluids to 14 lb/gal (1.7 SG). PHYSICAL & CHEMICAL PROPERTIES Appearance Finely ground white powder Specific Gravity 2.71g/cm3 Bulk Density 961 kg/m3 Molecular Mass 100.09 g/mol Solubility Insoluble APPLICATION Increase the density of drilling fluids to 13 lb/gal. Control formation pressures. RECOMMENDED TREATMENT The amount of NC-CARB required to increase the density can be calculated with the following formulas: Barite required: NC-CARB , lb/bbl = [980…

PRODUCT DESCRIPTION HAEMATITE (Fe2O3) is a weighting agent used to increase densities of oil-based and water-based drilling fluids up to 26 lb/gal. PHYSICAL & CHEMICAL PROPERTIES Appearance Black reddish powder Specific Gravity 5g/cm3 Solubility Insoluble in water APPLICATION Increase the density of drilling fluids up to 26 lb/gal (3115 kg/m3). Control formation pressures. Stabilize the borehole. RECOMMENDED TREATMENT The amount of HAEMATITE required to increase the density can be calculated with the following formulas: Barite required: HAEMATITE, lb/bbl = [1750 (W2 - W1)] / (41.66 - W2) Where W1 = Initial weight (ppg), W2 = Desired final weight (ppg) PACKAGING…

PRODUCT DESCRIPTION BARITE (BaSO4) weight material is a high-quality, drilling-grade barite (barium sulfate) used to increase the densities of oil-based and water-based drilling fluids to 21 lbs/gal (2516 kg/m³). PHYSICAL & CHEMICAL PROPERTIES Appearance Powder, various light colors; gray, pink, tan Specific Gravity 4.2g/cm3 Solubility Insoluble in water APPLICATION Due to its high density and low cost, BARITE is the most commonly used weighing material. BARITE weighed mud is as heavy as 20 PPG (S.G. 2.4) and still remains pump able, controls formation pressures, and stabilizes the borehole. RECOMMENDED TREATMENT The amount of BARITE required to increase the density can…
