Product Description

ECOFYBER^® F lost circulation material (LCM) is a blend of fine size micronized cellulosic fibers used to bridge and seal permeable formations in both water- or non-aqueous based drilling fluids. ECOFYBER^® is available in fine, medium and coarse grades so that optimum particle size can be selected to bridge the pores and pore throats of permeable formations.

Applications/Functions

• Bridges and seals permeable formations, control lost circulation
• Formulated as sweep pill to enhance hole cleaning

Advantages

• Effective bridging and sealing agent for a wide range of formations
• Available in fine, medium and coarse grades, allowing the most appropriate particle sizes to be used
• Inert material with minimal effect on mud properties
• Easily mixed and dispersed into the mud system
• Biodegradable and non-toxic material

Typical Properties

• Appearance: Brown powder or granula
• Bulk density: 0.35-0.51 SG

Recommended Treatment

• For seepage loss, add 10-20 ppb (29-57 kg/m³)
• For severe loss, add 20-35 ppb (57-100 kg/m³)
• Treatments in excess of 20 ppb (57 kg/m³) may cause reduction in electricity stability measurements in oil-based drilling fluids

Package

• 25 KG/SACK
