PAC-HVT for Drilling Mud
PAC-HVT for Drilling Mud
PAC-HVT for drilling mud is a kind of high-viscosity standard sodium polyanionic cellulose product. It is extensively used as a filter loss reducer or viscosifier for water-based drilling mud.
Characteristics
1. PAC-HVT is suitable for any mud in fresh water or saturated brine.
2. This product provides high mud yield and significant fluid loss reduction. It is particularly applicable to low-solids mud and no-solids brine mud.
3. The mud fluid added with PAC is able to inhibit clay and shale from dispersion and swelling in high-salt medium. It allows borehole wall pollution to get controlled.
4. Outstanding mud drilling fluid, workover fluid, and highly efficient fracturing fluid
5. PAC-HVT is made in full compliance with the performance index regulated by the 2007 edition of ISO13500 specifications.
