Background & Challenge
Drilled but uncompleted wells (DUCs) are a common issue among oil companies.
The issues may vary from one play to another, but the challenges of reducing cost, enhancing productivity and improving recovery rates remain the ultimate goals of pad drilling, regardless of the particular horizontal play.
Multi-well pads, batch drilling and zipper fracturing have improved the oil recovery of a well; however, has impacted the start of production substantially. These wells in waiting are considered drilled yet uncompleted or DUCs.
Most industry metrics track efficiency when a crew is on a well; drilling/completion days on a well. Our focus is measuring and finding ways to reduce the days between activities. While many operators share drilling and completion days, they rarely share DUC days and inventory backlog.
From our research we have found that non-productive days on a well could be as much as 100+ days per well; not including the time it takes to drill and complete the well.
Approach & Solution
Aligning incentives is our primary focus and we identify the operational bottlenecks on a portfolio level. Most of the efficiencies can be gained by integrating key inter-departmental processes; specifically the production and operations teams.
We addressed the spatial bottlenecks by optimizing the coordination of both the rig and the completions crew simultaneously within a given field. Mindfully orchestrating the positioning of both discrete events around a given field can dramatically reduce DUC days.
The solution resulted in the following:
- Production was reduced by 130 days
- Company was able to produce an additional 1.2M barrels within the production year
