Barite
Barite (barium sulphate) is the standard weighting agent for oil and gas drilling fluids, supplied to API 13A specification at 4.2 specific gravity.

- Barium Sulphate
- Grades / forms
- API 13A, 4.2 SG · Paint grade · Filler grade
Overview
Barite is a naturally occurring barium sulphate mineral, mined, cleaned and ground to a controlled fineness. Its value to a driller is density: with a specific gravity of 4.2, it raises the weight of drilling mud so that the column of fluid holds back formation pressure, prevents blowouts and keeps the well bore stable. It is chemically inert, insoluble and non-abrasive enough for mud pumps.
The API 13A specification sets the limits that matter downhole — minimum density, coarse and fine particle limits, and a cap on water-soluble calcium, which would otherwise interfere with mud chemistry. Outside drilling, the same mineral is used as a dense filler in paints, plastics and rubber, and in radiation-shielding concrete.
Applications
- 1Weighting agent in water- and oil-based drilling muds
- 2Kill fluids and well control
- 3High-density filler in paints, plastics and rubber
- 4Radiation-shielding and high-density concrete
- 5Raw material for barium chemicals
Packing & storage
Packing
- 25 kg & 50 kg bags
- 1–1.5 tonne jumbo bags
- Bulk for large campaigns
Storage & handling
Store dry on pallets. Barite is non-hazardous and chemically stable, but damp powder cakes and flows poorly through bulk systems.

Questions
Barite, answered.
API Specification 13A defines the minimum quality of drilling fluid materials. For barite it sets the minimum density (4.20 g/cm³, or 4.10 for the alternative grade), limits on coarse particles above 75 µm and fine particles below 6 µm, and a maximum of 250 mg/kg water-soluble alkaline earth metals measured as calcium.
4.2 SG barite is the standard API grade and needs less material to reach a given mud weight. 4.1 SG barite was added to API 13A to widen supply from lower-grade ore; it is cheaper but requires slightly more product per barrel and adds more solids to the mud.
Yes. Ground barite is used as a dense, inert filler in paints, powder coatings, plastics and rubber, as aggregate in radiation-shielding concrete, and as feedstock for barium compounds.
