AMC GEL™ is recommended for building a mud system with excellent hole-cleaning properties and filtration control in fresh to brackish water. Typical concentrations for AMC GEL™ range from 15 to 60 kg / m³ (5 to 21 lb / bbl). Like all bentonite products, the yield of AMC GEL™ decreases as water salinity increases. If chlorides are in excess of 8,000 mg / L the performance of AMC GEL™ will be significantly reduced. To avoid a reduction in performance, prehydrate in fresh water, where possible, before adding into the fluid system.
