Defer Drilling Excess Policy

A defer drilling excess policy allows you to modify the drilling schedule, delaying the drilling of new wells directly or indirectly connected to a facility until the facility has available capacity again.

Defer Drilling excess policy
  • Defer drilling wells when in excess in: Select the fluid to be measured from a list of out connectors defined for the facility.
  • Excess allowed: Percentage of potential rate allowed to be in excess before triggering the excess policy.

Wells can be prevented from being deferred by activating the Do not defer drilling wells in this group/reservoir option in some types of groups (see Well Groups) or in the reservoir Details Tab (Reservoir).

Using Defer Drilling

Since defer drilling excess policies are always triggered when a facility's production is lower that its potential, be aware that a downtime (where the production is intentionally lowered below the facility's potential - see Downtime Simulation) will cause excess policies to be triggered all the time. Therefore, care must be taken when using these two features concurrently.

The Defer Drilling policy affects both drilling and completion tasks: if a facility is in excess, it will prevent drilling of new wells even if the drilling in itself does not impact the routing. If a facility enters into excess after the drilling has started but before the completion has started, only the completion will be deferred.
