DESCRIPTION - Fritz FL-20 is a synthetic polymer used to control the loss of filtrate from water-based drilling fluids in high temperature applications. FL-18 displays exceptional performance in fresh, salt and KCl water-based fluids.
ADVANTAGES
• FL-20 provides exceptional filtrate control at temperatures up to 500°F (260 C).
• FL-20 eliminates the need for oil-based or synthetic fluids at high temperatures, thereby reducing the cost of the drilling fluid and altering the procedure for cuttings disposal.
APPLICATION
• FL-20 has a viscosifying effect on water-based fluids.
• It is ideally suited for most high temperature water-based fluid applications.
• FL-20 should interact well with all other additives.
PROPERTIES
• Off-White Powder
• Specific Gravity – 1.39
• Activity – 100%
• pH – neutral
• Packaged in 50 lb. bags
• Loading Rate – 2 to 12 lb./bbl
