Click on the ‘Controls’ button in the ‘Reservoir – Wells’ dialog to define the production
schedule for the well P01. The following dialog displays all controls at this well in a tabular
format, the table is empty when viewed for the first time. Click on ‘Add’ to create a new control
for this well.
Change the target type to ‘P(Surf)’, meaning that the well will be produced at constant surface
pressure. In the corresponding Value cell (highlighted in red) enter 2000 psia.
Keep the corresponding constraint type to ‘QTot(BH)’ (total bottomhole rate), and enter 15000
B/D for the value of this constraint:
Fig. B04.6 • History schedule for P01
Click on in the ‘Conditional constraints’ window to activate the constraint that closes
the well when the total bottomhole rate reaches the zero value.
In practice, those numbers imply that P01 will be produced at a constant surface pressure of
2000 psia unless the total bottomhole rate gets above 15000 B/D, in which case the
production will switch to a constant rate production fixed at the later value (of 15000 B/D).
The well P01 is now defined, we can move on with I02.
B04.3 • Perforations and Controls for I02
Select I02 in the ‘Reservoir – Wells’ dialog and click on ‘Perforations’. In the following dialog,
change MD start (starting measured depth for the perforation) to 6083 ft, and MD end
to 6096 ft.
