| Duratone E |
 |
DURATONE E, organophilic lignite, is used to control filtration rates in ester and olefin based drilling muds.
DURATONE E is stable at high temperatures and it can be used to control filtration rates in deep, hot wells.
It can also be used to improve emulsification of water in oil-based muds and to promote fluid stability.
DURATONE E meets environmental requirements for Norway.
*Applications/Functions: Reduce HTHP filtration rate, Promote stability of invert emulsion fluids.
*Advantages: Increases thermal stability of drilling fluids at temperatures beyond 500'F(260'C), Effective in all ester/olefin systems as well as inverts. |
