Drilling Mud Calculation - PDF Free Download - edoc.site

Density control computation Due to the barite's extremely large surface area, barite has tendency to adsorb a large amount of water from the mud system and thus increases the viscosity of drilling mud. This thickening is avoided when not only barite but also a minimum amount of water, to wet the barite, is added simultaneously.
