Overview

This analysis reveals how pressure and temperature affect yield stress in drilling fluids and clay dispersions, suggesting interactions are key.

Key Points

  • Yield stress increases with pressure but has varied responses to temperature in different systems.
  • At high shear rates, viscosity correlates with solvent viscosity, increasing under higher pressure conditions.
  • Clay dispersions show no aging of yield stress, while drilling fluids exhibit pressure-dependent aging.
  • Results enhance understanding of interactions between clay particles and emulsion droplets in these fluid systems.
