A few words can again be said on the options detailed in this dialog:
Rig constraints
The constraints box having been unticked, means that the forecast
can be put in directly, without any constraints on well availability.
Weather window: If all Months are ticked, there will be no rig
constraint. Workover can be added if it is expected that all wells need
a regular workover such as stimulation or pump replacements. The
well improvement option can be used if a workover increases
production from the well.
Drilling ability
Here the drilling performance is entered. Main parameter is the ‘Days
to Drill a Producer’, as the well comes on stream the applicable
number of days after drilling start-up. A drilling learning curve (Rig
Crew Learning Speed) with a value according to the acquired
experience can also be applied. In this case the maximum and
minimum durations must be entered and the learning speed can be
adjusted to: Very poor, Poor, Average, Good, Very good or Excellent
in order to take into account the drilling team ability (time to go from
maximum to minimum drilling duration). The plot illustrates the
applicable learning curve or the constant days to drill a well. Any
changes should be followed by a click on
. Note that the
calculation internal time step is months and drill time will be taken as
the nearest integer of months.
