OVCEL PAC-HV RD is purified dispersible PAC HV for easy mixing. It is a highly effective fluid loss reducer and secondary viscosifier for water based drilling mud system including salt water and saturated salt water drilling fluids. PAC-HV RD also meets all the performance requirements of PAC-HV in API 13A ,18 Section.
Anti-high Temperature Modified Starch OV-LOSE HT is modified starch by inserting hydration groups and high temperature stabilizer to improve the water solubility and temperature resistance (up to 130℃). And ensure its good fluid loss performance under both low and high temperature. SHR is an environmental friendly, low viscosity, salt resistance (up to saturation) filtration reducer.
Nitrile silicone polymer is composed of vinyl monomers and silane coupling agent by moderate crosslinking polymerization with free radical. It can be used in ultra-deep wells and soluble in fresh water, saltwater, saturated saltwater and seawater drilling fluids, and can be directly added to various water-base drilling fluids.
