Barite sag is related both to the drilling fluid properties and the drilling conditions and practices indicated above. The fluid properties affecting sag include rheology, solids content, particle-size distribution (PSD), and the chemistry of the fluid system. It is a commonly held view that the low-shear-rate (LSR) rheology of the fluid and its

Barite sag - PetroWiki

Mining: Barite mining in Missouri began around 1850; however, early lead mining operations began as early as 1725 in the same area, but barite was cast aside as a waste product at that time. Barite production data has been recorded from 1872 to present. The Washington County deposit is the major source of Missouri's barite production.

Barite Sag: Measurement, Modeling, and Management - OnePetro

Barite sag is the undesirable fluctuations in mud weight that occur due to downhole settling of the weighting agent. The problem has been exacerbated by the increased frequency of high-angle wells with the associated increase in particle settling rate which occurs in inclined fluid columns (Boycott effect 1 ).
