Viscosifiers & Rheology Modifiers
Polyacrylamide (PAM) Emulsion for Drilling Fluids
A water-soluble, high-molecular-weight polyacrylamide emulsion for drilling fluids. Through adsorption and bridging on cuttings and wellbore surfaces, it improves viscosity, cuttings transport and wellbore stability in oil, gas and shale-gas drilling.
APPLICATIONS
Application scenarios
- 01Viscosifying and cuttings transport in water-based muds
- 02Shale stabilization and wellbore protection
- 03Oil, gas and shale-gas drilling operations
