| Pac-L |
 |
PAC-L, polyanionic cellulose, provides filtration control in most water-based drilling fluids.
PAC-L can also be used as a thinner in sea water and brine-based fluids in small concentrations.
*Applications/Functions: Control filtration rates without significantly increasing fluid viscosity, Encapsulate shale to prevent swelling and disintegration
*Advantages: Effective in fresh water, salt water, and brine-based drilling fluids, Effective in small concentrations for filtration control, Is stable at temperatures up to 300'F(149'C), Effective in moderate to high pH systems, Does not require a bactericide, Nontoxic |
