Product Description

Product Description

CARBWATE is a specially treated high-quality micronized calcium carbonate used as weighting material in low-density fluids up to 14.0 ppg, including oil-based mud, workover, completion and drill-in fluids. CARBWATE is almost 98% soluble in hydrochloric acid, which minimizes permanent plugging of reservoir and increases oil/gas recovery.

Applications/Functions

• Increases fluids density up to 14ppg (1.68SG)
• Prevents fluid invasion of permeable zones
• Prevents loss of circulation during workover, completion and drilling operations
• Used in reservoir drilling fluids

Advantages

• High acid solubility
• Low settlement and sag potential
• Allows finer shaker screens to be used
• Reduced risk of downhole losses
• Helps to achieve higher ROP

Typical Properties

• Appearance: White Powder; Specific gravity: ≥ 2.7
• Calcium carbonate content, %wt: ≥90
• Particle size >75μm (wet screen), %wt: ≤3
• Particle size >45μm (wet screen), %wt: ≥5
• Particle size <6μm (sedimentation), %wt: ≤39

Recommended Treatment

• Specific drilling conditions will dictate a suitable concentration

Package

• 1 MT BIG BAG
