Polyanionic Cellulose
Polyanionic cellulose,PAC is easy soluble in water, having excellent properties of
salt-resistance, Calcium,Magnesium-resistance and reduce filtration loss. It can be
used in different drilling/completion drilling fluids, especially in salt water based
drilling fluids, seawater based drilling fluids and saturated-brine drilling fluids,can
reduce filtration very well.
Unique properties:
1) Evenly substituted, high transparency, control viscosity and reduce filtration
loss
2) Applied in fresh water,seawater and brine water based mud system
3) Formulated mud show good filtration loss, brine-resistance and high
temperature stable
4) Stable soft soil structure, prevent well collapse
5) While drilling through the rock surface, to slow down the solid accumulation in
mud.
6) Keep down the turbulence scale,to minimize the pressure loss in reverse-flow
system.
7) Improve mud yield, reduce filtration loss
8) Stable foam in mud
We have full range of Polyanionic cellulose for different needs:
PAC LV: Low viscosity PAC meeting API13A
PAC R: Regular viscosity PAC meeting API13A
PAC LVD: Rapid dispesible PAC L without agitation in fluids
PAC RD Rapid dispersible PAC R without agitation in fluids
Rules & regulations:
CAS: 9004-32-4
