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.
PAC-LV is a polyanionic cellulose polymer for water-based drilling fluids. It effectively reduces the filtration rate of many water-based drilling fluids, especially solids-laden fluids, without causing significant increases in viscosity or gel strengths.
PAC-R is a premium grade, purified, high viscosity, high molecular weight, polyanionic cellulose polymer designed to provide viscosity and reduce API filtration rate to water based drilling fluids.
Gilsonite is an asphalt that exist naturally and is available in a range of softening points. It is suitable for as a high temperature high presure control for filtration in oil-based conditions. Due to its unique compatibility, Gilsonite is frequently used to harden softer petroleum products.
PHPA is a specially treated high molecular weight Partially Hydrolyzed Polyacrylamide polymer for all water-based drilling fluids. It functions as viscosifying agent, shale and borehole stabilizer, encapsulator, bentonite extender, flocculation agent and assist with fluid loss control.
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.
