Micronized Cellulose Fiber Supplier and Manufacturer

Micronized Cellulose Fiber

MICRONIZED CELLULOSE FIBRE lost circulation material is a natural cellulose fiber that can be used in pills, sweeps and maintenance treatments with minimal adverse effect on rheology and filtration control properties. The cellulosic material helps decrease the permeability of the wallcake in all drilling fluid types. MICRONIZED CELLULOSE FIBRE lost circulation material additions do not interfere with pumping equipment or downhole tools when used in the proper concentration ranges. These materials are compatible with water and non-aqueous based fluids.

Helps reduce wallcake permeability and seepage loss
Helps seal and bridge depleted sands and microfractures



compatible with most water-based and oil-based muds
Has no adverse effects on rheological and filtration control properties of drilling fluids
Will not plug drilling equipment
Is biodegradable and nontoxic



1. As a preventive treatment, add 2-10 lb/bbl (5.7-28.5 kg/m³).
2. As a slug treatment, add 30-50 lb/bbl (85.6-142.7 kg/m³). 

Water-based fluids treated with MICRONIZED CELLULOSE FIBRE lost circulation material should be supplemented with a biocide such as biocide to control or eliminate potential bacterial contamination. Treatments in excess of 20 lb/bbl (57.1 kg/m³) may cause reduction in electrical stability measurements in oil-based systems.



Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet (MSDS). 



material is packaged in 55‐lb (25‐kg) multi‐wall, paper sacks. Store in a dry location away from sources of heat or ignition, and minimize dust.
