Introduction

BARITE 4.1 weighting material is a high-quality, drilling-grade barite used to increase the density of drilling fluids. This high-specific-gravity mineral is the most widely used weight material, has application in all drilling fluid systems and meets both API 13A and GB/T 5005-2010- Grade II for barite. BARITE 4.1 can be used to increase the density in oil-and water-based drilling fluids up to 20ppg (2.40SG). It is chemical inert and does not affect drilling fluid chemical properties.

Applications/Functions

• Increases drilling fluids density up to 20ppg (2.40SG)
• Control underground kicks and lost circulation with 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: ≥ 4.1
• Soluble alkaline Earth Metals (as calcium), mg/kg: ≤250
• Particle size >75μm (wet screen), %wt: ≤3
• Particle size <6μm (sedimentation), %wt: ≤30

Recommended Treatment

• Specific drilling conditions will dictate a suitable concentration

Package

• 1 MT BAG or available in bulk/CUSTOMIZED
