Product details
Polyanionic Cellulose
Polyanionic cellulose,PAC is refined quality of Cellulose ethers.It is readily dissolved in water, and have 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.
High viscosity PAC (PAC R,PAC HV)can be used as viscosifier and filtration control in drilling fluids to provide viscosity,and control filtration loss in drilling to protect well wall.Low viscosity PAC(PAC LV) is used in drilling fluids where does not require viscosity increase but demand excellent filtration loss control in well drilling.
Our PAC meets or exceeds the demand API13A/ISO13500.
Unique properties:
- Evenly substituted, high transparency, control viscosity and reduce filtration loss
- Applied in fresh water,seawater and brine water based mud system
- Formulated mud show good filtration loss, brine-resistance and high temperature stable
- Stable soft soil structure, prevent well collapse
- While drilling through the rock surface, to slow down the solid accumulation in mud.
- Keep down the turbulence scale,to minimize the pressure loss in reverse-flow system.
- Improve mud yield, reduce filtration loss
- Stable foam in mud
