Product Description

Product Description

MICROWATE^® 4.8 is a high-performance weighting agent made from manganese dioxide used in drilling fluids and completion fluids to increase density. Compared with barite, its unique features are: specific gravity of approximately 4.8, average particle size only 1 micron, particles with nearly perfect sphericity, and hardness is 1.5 times of barite. These characteristics enable the drilling fluid formulated with MICROWATE^® 4.8 to maintain relatively low rheology and lower equivalent circulating density, reducing the risk of sedimentation, which is beneficial for extended reach wells or ultra-long horizontal wells drilling, especially in ultra-deep wells and high-temperature wells, and also conducive to reservoir protection.

Applications/Functions

• Used alone or in combination with other weighting materials to increase the density of drilling fluids
• Used in restricted ECD applications but not limited to: depleted wells, deep water, narrow margin, high temperature wells, ultra-deep wells
• Effective sag control for reduced non-productive time

Advantages

• Drilling fluid weighted by MICROWATE^® 4.8 can achieve lower ECD and low-shearing thinning properties, which can speed up tripping in/out operations and ROP
• Increases production rate and reduces formation damage due to its particle size and acid solubility
• An ideal weighting material for HPHT wells and ultra-deep wells

Typical Properties

• Appearance: Black to brown Powder
• Specific gravity: 4.8
• D50: 1μm

Recommended Treatment

• Specific drilling conditions will dictate a suitable concentration

Package

• 1 MT BIG BAG
