Product description:
 
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)      Formulated mud show good rheology control,to inhibit clay or shale swell or collapse, hence to prevent well contamination
5)      Stable soft soil structure, prevent well collapse
6)      While drilling through the rock surface, to slow down the solid accumulation in mud.
7)      Keep down the turbulence scale,to minimize the pressure loss in reverse-flow system.
8)      Improve mud yield, reduce filtration loss
9)      Stable foam in mud
