Benefits

The NewLig additive delivers superb fluid loss control properties at elevated temperatures and highly efficient control over viscosity and gel strengths.

Application

NewLig filtration control agent is effective in water-based drilling fluids containing up to 15,000 mg/L chlorides and in temperatures in excess of 400°F (204°C). It is also an emulsifier for oil-in-water emulsions.

Treatment Recommendation

Initial treatments are best determined by pilot testing. The NewLig additive is effective at low treatment levels, with normal concentrations at 2-5 lb/bbl. Thinning effectiveness diminishes at a pH below 9.0 and with chlorides concentrations greater than 15,000 mg/L.
