One-pot and two-step synthesis of a high-temperature and high-salinity resistance filtrate reducer for water-based drilling fluids

Key Points

• The one-pot synthesis approach demonstrated enhanced filtrate reducer performance against high temperatures and salinity, ensuring drilling fluid stability.
• Key metrics show significant stability improvements in filtrate reduction, maintaining functionality under extreme drilling conditions.
• Observational analysis of synthesis pathways indicates effective integration of both synthesis methods within drilling fluid applications.
• Findings suggest the need for further development in filtrate reducers for future high-performance drilling environments.
