| Therma-Chek |
 |
THERMA-CHEK, vinyl amide/vinyl sulfonate copolymer, provides filtration control in water-based drilling fluids at temperatures up to 450'F (232'C).
THERMA-CHEK can be used to supplement other filtration control agents at 300-375'F (149-191'C).
THERMA-CHEK is the primary filtration control agent in the THERMA-DRIL high temperature water-based drilling fluid system.
*Applications/Functions THERMA-CHEK can be used in fresh water and salt water systems to improve filtration control and impart supplementary viscosity at temperatures up to 450'F(232'C).
*Advantages: Provides filtration control for a wide variety of mud systems, Excellent high temperature stability, Environmentally responsible, Provides secondary viscosity, Is tolerant to salt and divalent ions |
