Barite Powder | Oilfield Weighting Agent
一、 Product Brief
Industrial-grade Barite Powder, also known as natural barium sulfate powder, is a high-density inert mineral powder processed from high-purity barite ore. It is the most mainstream and reliable oilfield weighting agent in petroleum drilling engineering. With high specific gravity, stable chemical inertia, low hardness and non-toxic characteristics, barite powder is professionally applied to increase drilling fluid density, balance formation pressure, and prevent well blowout and collapse. It features stable performance, wide adaptability and low comprehensive cost, serving as a core auxiliary material for onshore and offshore oil and gas drilling operations.
二、 Industrial Application Scope
1. Petroleum Drilling Weighting Agent (Core Application)
As a special oilfield weighting agent, barite powder is the essential raw material for preparing weighted drilling mud. It effectively increases the density of water-based and oil-based drilling fluids to balance underground formation pressure, inhibit oil and gas overflow, and avoid wellbore collapse and blowout accidents. The product has stable physical and chemical properties, does not react with drilling fluid additives, and will not damage mud rheology. It is suitable for conventional wells, deep wells, ultra-deep wells and high-pressure complex oil and gas strata, ensuring safe and stable drilling construction.
2. Industrial Auxiliary Applications
In addition to oilfield drilling, high-purity barite powder can be used in industrial fields such as paint coating, chemical industry, rubber and plastic filling, and radiation protection. It acts as a high-density filler to improve product wear resistance, corrosion resistance and surface finish, meeting diversified industrial production needs.

四、 Product Superiority
- High Weighting Efficiency: High specific gravity and high barium sulfate content ensure rapid mud density improvement with low dosage, effectively balancing formation pressure.
- Stable & Inert Performance: Chemically inert without reaction with drilling fluid additives, no damage to mud viscosity and rheological properties, ensuring long-term stable mud performance.
- Low Impurity & High Purity: Strictly controlled water-soluble salt and harmful impurity content, effectively avoiding underground pollution and pipeline blockage.
- API Standard Compliance: Fully compliant with international oilfield drilling standards, suitable for global petroleum exploitation projects with high industry recognition.
五、 Storage & Handling
Oilfield-grade barite powder should be sealed and stored in a dry, ventilated and dust-proof warehouse to prevent moisture agglomeration and impurity contamination. Avoid long-term exposure to humid air and heavy extrusion. During on-site drilling operation, the powder should be uniformly added into the drilling mud circulation system with stirring. The dosage should be adjusted according to actual formation pressure and mud density requirements to achieve optimal weighting and pressure stabilization effect.
