Keywords: hydraulic losses calculation, high pressure/high temperature (HP/HT) influence, piston/pressure surge simulation, hydraulic optimization
Annotation:
The article considers an example of hydraulic lossescalculation that occur during the circulation of a water-based drilling fluid. Literature analysis showed that the deviation between the measured and predicted values for vertical and horizontal wellbores is in the range of (0–1) MPa. Also, based on a review of the literature sources, clarifications are considered that require consideration when modeling the behavior of non-aqueous drilling fluids and brines under high pressure/high temperature (HP/HT) conditions.
