We will accept all default values in this dialog, knowing that the various options are:
Gas lift
Default values ensure that gas lift will start when a well cuts 15 %
water and the required gas volume per well is 2 MMSCFD.
Gas usage
The necessary field fuel gas is defined together with the volume of
allowed flare gas. If the box ‘Export Gas’ is ticked no gas will be
injected. By default the date of exported gas coincides with
production start-up.
Water usage mode
The default case specifies that 80 % of voidage (qoBo +qwBw) will
be replaced by the aquifer influx, requiring 20 % of voidage volume
to be replaced by injected water. Total Reservoir Voidage times
(Replacement_Ratio-Voidage_Replaced_By_Aquifier). Replacement
ratio: percentage of total withdrawal to be replaced by water
Water injector
The default value of 20,000 stb/d specifies the injection capacity of
each injection well and is used to determine the number of required
water injection wells.

Click on the Tab ‘Drilling/Workovers’. Apart from the rig constraints box that you need to
uncheck, you can keep all default values in this dialog:
