Method for mitigating barite sag in water-based mud with thermochemical fluid

A system for mitigating particulate settling in a drilling fluid, comprising:

• a processor configured to perform operations of:
• obtaining a set of rheological data for a first drilling fluid having a composition, wherein the set of rheological data comprises a measured viscosity value;
• determining a thermal effect of the measured viscosity value;
• determining, based on the thermal effect, a predicted viscosity value for a second drilling fluid having a composition that is similar to the composition of the first drilling fluid;
• and
• determining, based on the predicted viscosity value, an amount of a thermochemical fluid to add to the second drilling fluid to increase a temperature and a viscosity of the second drilling fluid such that settling of a particulate is mitigated.
