Product Description

Product Description

BARITE 2μm weighting material is a high-quality, ultrafine barite used to increase the density of drilling fluids. This high-specific-gravity mineral is the most widely used weighting material, has application in all drilling fluid systems and meets both API 13A specifications and Q/SH 0282-2009 Special Grade for barite. BARITE 2μm can be used to increase the density in oil-and water-based drilling fluids up to 22ppg (2.64SG). It is chemical inert and does not affect drilling fluid chemical properties. Ultrafine Barites are available in 3 standard grind sizes: 2μm, 3μm, 5μm. The numbers reflect the nominal median particle size(D50) of the product.

Applications/Functions

• Increases drilling fluids density up to 22ppg (2.64SG)
• Controls underground kicks and lost circulation with barite slugs

Advantages

• Standard weighting material for drilling fluid
• Essentially chemically inert and insoluble, functions only in a physical manner
• Does not react with other drilling fluid additives or interfere with their function
• Minimally abrasive

Typical Properties

• Appearance: Gray Powder
• Specific gravity: ≥ 4.3
• Soluble alkaline Earth Metals (as calcium), mg/kg: ≤150
• Particle size >75μm (wet screen), %wt: ≤3
• Particle size <6μm (sedimentation), %wt: ≤25

Recommended Treatment

• Specific drilling conditions will dictate a suitable concentration

Package

• 1 MT BIG BAG or available in bulk
