AMC BARITE™ is added through a mud hopper or suitable shearing device. The amount of AMC BARITE™ required to increase the fluid density can be calculated using the following formulas: AMC BARITE, kg / m³ = 4200 (w2 – w1) / 4.2 – w2. w1 = Initial mud weight in specific gravity. w2 = Desired mud weight in specific gravity.
