Barite Powder

Our API-grade barite has minimum specific gravity of 4.2 g/cc per API 13A requirements. Using barite, drilling mud density can be increased from water density (8.33 ppg) up to approximately 19–20 ppg, covering the full range of formation pressure control requirements in oil and gas drilling.

Barite particle size controls suspension efficiency, settlement rate, and mud density stability. API 13A specifies 97% of barite particles must pass through a 75µm sieve. Finer particles improve suspension but increase viscosity contribution. Our controlled PSD grades balance these properties for optimal downhole performance.

Barite itself is chemically inert, non-toxic, and does not bioaccumulate. However, disposal of barite-containing cuttings and drilling waste must comply with local environmental regulations, particularly for offshore operations.

API 13A grade barite meets American Petroleum Institute standards with specific gravity ≥4.2 g/cc, 75µm sieve residue ≤3%, and controlled soluble alkaline earth metals. OCMA grade meets equivalent European/international standards. Both are designed for drilling fluid use.

Barite's low hardness (Mohs 3–3.5) compared to formation minerals (quartz at Mohs 7) means barite particles cause significantly less abrasive wear to drill bits, mud pumps, pipe, and downhole tools compared to harder weighting agents like hematite (Mohs 5.5–6.5), reducing maintenance costs.
