Application:
PAC-HV is for water-based drilling fluids, which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environment.
PAC-LV is for use in solids-laden, water-based drilling fluids, which can effectively reduces the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strength.
Petroleum grade Product features:
1, high degree of substitution, good uniformity of substitution .
2, high transparency, viscosity and water loss can be controlled .
3, suitable for fresh water, sea water, saturated brine slurry .
4, stabilize soft soil structure, prevent collapse of wall of a well .
5, can improve mud-making volum, reduce filteration loss .
6, has excellent performance in drilling of oil .
