Fluid loss control agents

Borregaard’s BioDrill® FM range are high-temperature stable and contaminant tolerant filtration control additives.

Water-based mud systems naturally form a clay-based filter cake at the interface between the formation rock strata and the drilling fluid. Our BioDrill FM fluid loss control agent decreases the filter cake’s permeability, preventing migration of drilling mud into sensitive formation-producing zones. The treated filter cake also prevents formation fluids from migrating into the drilling mud column.

Our sustainable lignosulfonate-based fluid loss control additive offers excellent performance at bottom hole temperatures up to 205°C (400°F). It is particularly efficient in calcium, magnesium and chloride contaminated systems like gypsum/dolomite or salt formations and seawater.

The BioDrill products are part of the OSPAR List of Substances Used and Discharged Offshore, which are Considered to Pose Little or No Risk to the Environment (PLONOR)


  • Easy to dissolve
  • Stable over a wide pH range
