3 μm Ultrafine Barite
Catalog NO.: AIMRSE-CHM-ADD-177 Manufacturer PN: CHM-BAR-3U
• Standard weighting agent material in drilling fluids; inert, insoluble, has no effect on other materials, does not produce any chemical reactions, and is abrasion-resistant.
Elevates drilling fluid density up to 2.64SG for addressing well control challenges such as well kicks, employing barite plugs for plugging operations.
This product is a high-quality ultrafine barite-based weighting material used to increase drilling fluid density. It is widely applicable to all drilling fluid systems and complies with both the international API 13A standard and Sinopec's Q/SH 0282-2009 premium grade standard. It can elevate the density of water-based or oil-based drilling fluids to a maximum of 2.64 SG. This material is inherently inert, does not react with other products, and does not affect the chemical properties of the drilling fluid system.
