Disclosed are systems and methods for the real-time detection and measurement of sag within a deviated borehole. One method includes measuring a first pressure at a first time at a point within the borehole, predicting a characteristic of the drilling fluid at the point using a computer model, thereby obtaining a predicted characteristic, calculating the characteristic based on the first pressure, thereby obtaining a calculated characteristic, and determining whether sag has occurred based on a comparison between the calculated characteristic and the predicted characteristic. |
