API 13A Standard PAC Low Viscosity Oil Drilling Grade PAC

API 13A Standard PAC Low Viscosity Oil Drilling Grade PAC

PAC-L is a polyanionic cellulose polymer, which is an extremely effective filtrate reducer in fresh or salty water. It also acts as a thinner in salty water in low concentrations.

Product Details


HB PAC-L can be used in any type of water based drilling fluid, including saturated salt water fluids. It will effectively reduce filtrate loss without increasing viscosity. HB PAC-L is an excellent shale encapsulater and inhibitor in medium to high concentrations.



1.         HB PAC-L is effective in all types of water based muds, including salt saturated

2.         Effective in the reduction of filtrate in small concentrations

3.         Effective in the reduction of shale dispersion at medium to high concentrations

4.         Effective at moderate to high pH

5.         Non toxic and will not ferment

6.         With a higher D.S, HB PAC-L has a better property of high temperature and salt resistance

7.         API 13A standard A.V. : max 40 cps, Filtrate volume: max 16ml
