High Viscosity Polyanionic Cellulose (PAC-HV)
 
The drill and completion fluid proficiency is an important separate of petroleum drill project and plays a critical character in ensuring safe, high-quality and fast drill. As a kind of treating agent to improve the drill and completion fluid performance, the cellulose ether has an important role in reducing fluid loss and increasing viscosity .
PAC HV can improve the curdling stability of the system by forming a relatively slurred solution concentration layer on the particle surface of drill fluids, reduce the electrostatic attraction between particles by absorbing all right particles of mud and therefore increasing the surface charge of particles, and the permeability of percolate patty by enhancing the viscosity and capability to plug holes of filter

PAC HV well disperses in all water-base drill fluids and applicable from fresh water to saturated salt water drilling fluids. In low-solid and solid-free drilling fluids, PAC HV can strikingly reduce the percolate loss a well as the filter patty thickness, and shows firm inhibitory effects on the shale hydration .
Description
It is a high quality water soluble cellulose derivative. In shape of white or luminosity yellow free-flowing powderize, it is odorless, tasteless, non-toxic & non-fermented, and has good thermal-stability and senior high school salt immunity. It is soluble into water to form slurred liquid, and it wide used in water-base drill fluid so as to enhance the bore fluid viscosity and control the fluid personnel casualty. It meets API external standard .
