After selecting each well, click now on the ‘Wellbore’ icon to edit the wellbore model
that will be applied to compute the pressure drop along the well.
In the following dialog select ‘All trajectory’ for the wellbore usage (the options ‘Only above
reservoir’ and ‘Only hydrostatic gradient’ should not be chosen in a thermal context).
The choice of ‘All trajectory’ implies that the wellbore model will be used along the reservoir
section up to the wellhead.
The heat loss coefficient is the overall heat transfer coefficient between the wellbore center
and the external formation (accounting for combined effects of tubing, casing, cement,…).
Above the reservoir top, the external temperature is assumed to remain constant.

In this example, keep the proposed values and make sure that the option ‘All trajectory’ is
checked for both wells.
We need now to define a well control for these wells. To do so, select the Producer and click on
‘Controls’. In the Well Controls dialog, click on ‘Add’ to create a new control for this well and
set it as a producer with total bottom hole rate of 15000 B/D, as in figure C01.21.
Click on ‘Add’ in the Conditional Constraints box with close well with zero rate.
Perform the same operation for the second well, setting it as a water injector (with a
bottomhole rate of -15000 B/D), an injection temperature of 50 degrees Fahrenheit and a
starting date at 01/01/2012 (one year after the beginning of production) as in figure C01.22.
