Walnut Shell
Walnut Shell is a hard fibrous material, chemically inert, nontoxic & biodegradable material used as a Loss Circulation Material for Drilling applications. It is essentially manufactured by grinding specialized walnut to specific Sizes and can be used in all types of Fluid Systems of Various Densities. Walnut is at times used as a Nut Lubricant to increase lubricity and Reduce Torque and Drag
Common Name: GLO NUT
Application:
Walnut is widely used to control lost circulation in water & oil base drilling fluids. It may be utilized by itself in re-circulated fluids or in pill form with fibrous & flake material at times it is also used as a Lubricant to increase Lubricity and reduce Torque and Drag
Advantages
- It is widely used Loss Circulation Material for Seepage Control
- Walnut shell is compatible with both water and Oil based Drilling Fluids
- Nontoxic and Completely Biodegradable
- Good Lubricating Properties reduces Torque and Drag and Bit Baling
- Compatible with other Fibrous and Flaky LCM Materials
- Non-Fermenting and Chemically Inert
