Prevention of Barite Sag in Water-Based Drilling Fluids by A

2020年3月30日 Barite sag is a challenging phenomenon encountered in deep drilling with barite-weighted fluids and associated with fluid stability. It can take place in vertical and directional wells, whether in dynamic or static conditions. In this study, an anti-sagging urea-based additive was evaluated to enhance fluid stability and prevent solids sag in water

AMC BARITE™ - AMC Drilling Optimisation

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.
