Shale Gas Drill to Fill
Creating a Drill to Fill Program
This section covers 'Drill to Fill' functionality, where wells are shifted in time to meet but not exceed production limits. Drill to fill monitors volumes through a network node and controls drilling program's well start dates.

Drill to Fill Usability
Changing a drilling program to 'Drill to Fill' is a good idea when the original drilling schedule's maximum deliverability exceeds the constraints of the facility it flows to. Drill to Fill controls the drilling schedule while honoring all resource rules, including:
- Access Restrictions
- Rig availability Timing
- Frac Timing
- Gathering system Construction

On the graph above on the left, the refill capacity trigger is greater than or equal to 100%, while the maximum target refill value is well above 100%. On the graph above to the right, the refill capacity trigger is well under 100%, while the maximum target refill value is near 100%.
