In order to achieve 100 bbl of 13.0 ppg mud weight up with barite, you must have 88.0 bbl starting volume of 10.0 ppg mud. Please find the Excel sheet for calculating Barrel of starting volume of original mud weight required to give a predetermined final volume of desired mud weight with barite.
Barite or weight material sag is a problem of drilling mud and it occurs when weighting material (barite, calcium carbonate, etc) separate from liquid phase and settle down. The method is based in part on continuously measuring fluid density during the first circulation after the fluid has been static after some time.

A symptom of barite sag would be when density checks at the shakers see a drop in density, followed by an increase, to be followed eventually by mud weight of the correct density. This idealized cycle of mud weights seen at the shale shakers may not be seen as new barite additions could mask it. Historical data has shown that weight ...

Volume (barite) = Weight (barite) / Density (barite) Assuming a weight of 1000 lb and a density of 4.5 lb/gal, we find that the volume of barite required is approximately 222.22 gallons. On the other hand, the volume of hematite required can be calculated in the same way, assuming a weight of 1000 lb and a density of 5.2 lb/gal.
It is a high quality drilling grade Barite (Barium Sulphate) used to increase the density of drilling fluids. It is the most widely used drilling weight material due to its high specific gravity. It meets API 13A requirements. Barytes (or barite) is a naturally occurring mineral form of barium sulphate. It is extracted by both surface and underground mining.
assessment of either U.S. or global barite resources has been conducted since the 1980s. Substitutes: In the drilling mud market, alternatives to barite include celestite, ilmenite, iron ore, and synthetic hematite that is manufactured in Germany. None of these substitutes, however, has had a major impact on the barite drilling mud industry.
The density of barite is typically measured in grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L). The density of pure barite mineral ranges between 4.10 g/cm³ to 4.30 g/cm³. However, the density of commercially available barite used in drilling mud applications is usually standardized to be around 4.20 g/cm³.
For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure water. As an example, a 17.5 lb/gal mud has a specific gravity of 2.1.
