The unconventional reservoir module (URM) analysis is a single-phase analysis; therefore you should be cautious when applying it to cases where a well exhibits two-phase flow. For oil wells, we can expect two-phase flow after the flowing pressure drops below the oil bubble point pressure. The Saturated Filter option can be used to identify the portion of the data where flowing pressure is below the bubble point pressure (oil and gas flowing in the reservoir).
To use this option:
Click the Data Filter icon on a Square Root Time or FMB plot; then click the Fully Automatic icon on the Data Filter plot.
Note: The saturated filter uses the oil bubble point pressure set in the Properties editor; therefore, it is important to set it accurately.
