Walnut (F/M/C) is ground walnut shell, graded into fine, medium and coarse sizes, used to seal lost circulation zones during drilling. Drilling teams searching for a walnut shell LCM supplier in UAE use it to bridge fractures and keep mud in the hole.
Corofy supplies walnut shell LCM from its Dubai warehouse to drilling contractors, mud companies and oilfield distributors across the UAE, the GCC, Africa and Asia. It is one of our oil & gas chemicals.
Walnut Shell LCM Overview
Lost circulation, where drilling fluid flows into fractures, vugs or highly permeable zones, is costly and can threaten well control. Lost-circulation materials (LCM) are added to the mud to plug these openings.
Ground walnut shell is a hard, granular, plant-based material, often referred to as nut plug. Its particles lodge in fractures and pore throats and build a bridge that other fine solids can then seal against. Offering fine, medium and coarse grades lets the mud engineer match particle size to the size of the losses, and blend grades for a wider particle size distribution.

Applications of Walnut Shell LCM
Walnut shell is used in both preventive and remedial lost circulation treatment.
Lost Circulation Pills
- Coarse and medium grades used in pills to seal larger fractures and vugs.
- Combined with other LCM types for a broad particle size range.
Bridging & Seepage Control
- Fine grade added to the active mud system to reduce seepage losses.
- Helps build a bridge in permeable or depleted zones.
Mud System Compatibility
- Inert material that can be used in water-based and oil-based muds.
- Grades can be blended on site to suit loss severity.
Walnut shell is popular because it is hard and resists crushing under pressure, while remaining non-corrosive and easy to handle. It is also simple to mix, either into a pill in a separate tank or straight into the active system through the hopper. Particle size selection matters more than quantity: the right grade bridges, the wrong grade passes through.

Handling, Storage & Safety
Walnut shell is a natural, non-hazardous material in normal use, but handling can create dust. Follow the Safety Data Sheet, wear a dust mask and eye protection when mixing, and keep bags in a dry, covered area off the ground to prevent moisture pick-up and contamination.
