| N-Dril LO |
 |
N-DRIL LO, modified cellulosic polymer, provides filtration control in water-based drilling fluids.
Because of its molecular weight, it provides effective filtrate control and only small increases in mud viscosity with normal use.
N-DRIL LO is recommended for use in wells where bottomhole temperatures do not exceed 250'F
(121'C).
N-DRIL LO is not affected by the presence of calcium or magnesium at moderate pH levels because of its nonionic character.
*Applications/Functions: N-DRIL LO can be used to provide filtration control under static and dynamic conditions.
*Advantages: Tolerates calcium or magnesium at low-to-moderate pH levels because it is nonionic, Provides stable filtration control in sea water N-DRIL LO systems while drilling cement, Effective in small concentrations for filtration control |
