Overview

Experimental study demonstrates accurate Herschel–Bulkley rheology prediction for water-based drilling fluids under high pressure and temperature, improving ultra-deep wellbore pressure calculations.

Key Points

To establish a temperature–pressure-coupled correction model that accurately predicts Herschel–Bulkley rheological parameters for water-based drilling fluids in ultra-deep wells using ambient-condition baselines.
Tested three water-based drilling fluids at wide temperature and pressure conditions up to 210 °C and 206.5 MPa.
Evaluated seven rheological models across multiple dimensions, including extreme-condition performance, low-shear-rate behavior, absolute shear-stress deviation, and model complexity.
Developed a temperature–pressure-coupled model calibrated with ambient-condition Herschel–Bulkley baselines and validated it against field circulating-pressure-loss data.
The Herschel–Bulkley model provided the highest accuracy across all tested fluids, achieving mean R² values above 0.997 and mean absolute percentage errors below 2.5%.
Calculations using the corrected Herschel–Bulkley parameters yielded mean shear-stress errors no greater than 4.04%.
Field validation confirmed that the coupled model decreased the mean error in circulating-pressure-loss predictions from 2.72% to 0.78%.
