Origin & supply chain +
Khuzdar — Pakistan's Premier Barite Belt
The Khuzdar district in Balochistan hosts stratabound barite mineralization within the Cretaceous Parh Group — geologically classified as one of the world's most significant barite provinces, with documented reserves exceeding 50 million tonnes. Bare Syndicate sources barite from established mines that have been operating for decades, ensuring consistent SG 4.2+ ore quality. Lumps are road-hauled to our grinding facility on the outskirts of Karachi, where Raymond mills and air-classifiers produce API 13A-compliant powder under tight QC. Finished bags are stored in dry covered warehouses, sampled by SGS at load port, and dispatched directly to mud-engineering subsidiaries of Halliburton, Schlumberger, M-I SWACO, and major NOC drilling divisions worldwide.
FAQ +
What is barite used for in oil & gas drilling?
Barite (BaSO₄, SG 4.2) is the primary weighting agent in drilling muds. Its high specific gravity allows mud engineers to control formation pressure, prevent blowouts, suspend drill cuttings, and stabilize the wellbore — across both onshore and offshore operations.
What is API 13A and why does it matter?
API Specification 13A defines the physical and chemical requirements for drilling-grade barite: minimum SG 4.20, water-soluble alkaline earth metals limit, and a strict residue-on-200-mesh requirement. Compliance is mandatory for IADC-contracted rigs and most national oil companies. All Bare Syndicate powder ships with API 13A test certificates.
What is the difference between lumps and powder?
Lumps (raw mined, 0–300 mm) are sold to grinding plants and mud-chemical companies who micronize on-site. Powder is pre-ground to API 13A spec (200 mesh, ≥95% passing 75 µm) and is ready to dose directly into the mud system at the rig — saving the buyer grinding cost and CapEx.
Where is your barite mined?
From the Khuzdar district in Balochistan, Pakistan — one of the world's largest stratabound barite belts, with established operations producing premium SG 4.2+ ore for over four decades.
How is barite shipped to drilling regions?
Lumps ship in bulk vessels or 25 MT containers FOB Karachi to grinding plants worldwide. Powder ships in 1.5 MT jumbo bags inside 20-foot containers, typically to drilling hubs in the GCC, North Africa, West Africa, and Southeast Asia. Lead time from order to FOB is 3–4 weeks.
