Shale Control Additives


PAC-HV is water-soluble polymer for water-based drilling fluids. It is effective in reducing the filtration rate of many water-based oil and gas drilling fluids. It can also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environments.

EPISOL is a fluid loss agent compounded from oil-soluble polymers and modified asphalt. It can effectively control the fluid loss of oil-based drilling fluids, especially under HTHP conditions. It can be used in diesel-based, white oil-based, and synthetic-based drilling fluids at the same time and is less affected by different types of surfactants in the system.

S-TROL3 is a shale inhibitor that can be effectively adsorbed onto the surface of clay to prevent damage to the oil/gas bearing zones caused by hydrated expansion and dispersion of water-sensitive minerals. It is suitable in a wide range of applications given its long-term effectiveness, simple usage, low dosage and erosion resistance to acids, salts, alkalis and oil water.
