Barite

Barite (BaSO4) is used as a weighting agent in both water and oil base drilling fluids.
FEATURES AND BENEFITS
Barite is supplied to meet API specifications.
Specific Gravity
Minimum 4.2 3% residue (max.) on US Sieve #200 (74 microns)
5% residue (min.) on US Sieve #325 (44 microns)
Due to its relatively low cost and high density, Barite is the most commonly used weight material in drilling fluids.
Barite weighted fluids can achieve a maximum density of +- 2400 kgm3.
RECOMMENDED TREATMENT
The quantity of Barite required will depend upon encountered formation pressures and Operator’s specifications
