Barite Segregation in Inclined Boreholes

2001-6-1  In weighted drilling mud barite tends to segregate slowly. In directional drilling operations the settling process is accelerated. Barite settles in the lower side of the borehole and starts sliding when the borehole has an inclination above 30˚. This phenomenon is known as barite sagging. Sagging can lead to drilling
