...) for water set at high flow rates (17,500 B/D for in-well and 34,000 B/D for ALS). Thus, when the pumps deal with viscous fluid, the curve will have a BEP closer to the current operating point. Design boundaries of the in-well ESP and the ALS are provided in the complete paper, as are some of the...

If bubbles are detected during the monitoring period, the well is deemed to have a positive vent flow. Consequently, the source...

The results show that the mean slug length initially increases with the distance from the inlet but that this increase slows and the mean slug length typically reaches a value between 20 and 50 diameters at the outlet. At low flow rates, slug-length distributions tend to be extremely wide. At...
