We will not use a wellbore model for this well (the pressure drop will be derived from the
hydrostatic gradient only), so we do not need to visit the ‘Wellbore’ dialog.
Click now on ‘Controls’ to create the following water injection control:
Fig. B04.9 • History schedule for I02
Change the mode from ‘Producer’ to ‘Injector’ and the target type to ‘QWat(BH)’ (water
bottomhole rate), enter a value of -5000 STB/D for the injection rate controlled by a maximum
surface pressure of 10000 psia.
Click on in the ‘Conditional constraints’ window to activate the constraint that closes
the well when the total bottomhole rate reaches the zero value.
Finally, click on OK to exit the ‘Reservoir – Wells’ dialog: both wells are defined.
B04.4 • Checking the Well Positions
Before proceeding with the next simulation step – the grid construction, we can have a last
check of the current geometry.
Back to the 2DMap, you can first hide the bitmap if you did not do so before ( ). Then, move
the cross-section (red) line to make sure that it goes through each well – you may add a new
node on the line with a single click, then use the ‘attraction law’ of the well (its node will turn
green) to release the mouse when a cross-section node is moved close-by:
