Typical Workflow

Typical Workflow in the DevPlan Schedule Builder

This document outlines the typical, step-by-step workflow for a user building a Field Development Plan (DevPlan) using the Schedule Builder application. Following this workflow ensures that operational constraints, well interferences, and spatial realities are all properly accounted for.

Step 1: Define Global Constraints

Before building your schedule, you need to set the macro constraints for your project.

  • Action: Open the Settings Panel (located in the left sidebar).
  • Tasks:
    • Define your operational limits: set the maximum number of simultaneous Drilling Rigs and Completion Rigs available.
    • Set baseline operational durations (e.g., average drilling days per well, completion days).
    • These limits will govern the warnings and indicators you see later as you build the schedule.

Step 2: Build the Base Schedule

Sequence your pads and wells over time to create a baseline timeline.

  • Action: Navigate to the Timeline View tab (center) and the Table Panel (right sidebar).
  • Tasks:
    • Order the pads logically based on business needs.
    • As you adjust dates and sequences, keep an eye on the Rig Indicator in the top header. It will alert you (turning yellow/orange with a warning icon) if you have scheduled too many overlapping operations, exceeding the rig count you defined in Step 1.
    • Look at the footer for real-time stats: Total Pads, Total Wells, First Drill date, Last Prod date, and the overall Project Duration.

Step 3: Configure Parent-Child Interference

Wells drilled close to older, existing wells will experience depletion effects.

  • Action: Switch to the Parent-Child Config tab.
  • Tasks:
    • Enable the interference logic.
    • Set your spatial bounds (distance thresholds) and time bounds (how many months a well must be producing to be considered a “parent”).
    • Define the severity of the interference (e.g., 10% IP loss, 5% EUR degradation) to ensure realistic production forecasts for your infill wells.

Step 4: Configure Frac Hit (Shut-in) Impacts

When a new well is being hydraulically fractured, nearby producing wells must often be shut in and may suffer permanent damage.

  • Action: Switch to the Frac Hit Config tab.
  • Tasks:
    • Enable Frac Hit effects.
    • Set the detection ranges (Perpendicular, Parallel, Cross-layer).
    • Define the event response: how long the well is shut in (e.g., duration of the pad completion), ramp-up time, and any permanent long-term production loss.

Step 5: Validate Spatial & Production Results

Ensure your timeline makes sense geographically and check the resulting production curves.

  • Action: Use the Spatial View tab and the Production Curve panel (bottom).
  • Tasks:
    • Spatial View: Play through the timeline to watch how rigs move across the map. Ensure rig moves are geographically logical to minimize transportation time.
    • Production Curve: Open the bottom panel to see the aggregate field production. Check if the parent-child degradations and sudden frac-hit shut-ins create the expected impacts on the combined field rate.

Step 6: Refine, Export, and Apply

Once the schedule passes both operational constraints and physical interference rules, finalize the plan.

  • Action: Use the action buttons located in the footer.
  • Tasks:
    • Click Export CSV if you need to share the schedule data externally or run custom reports in Excel.
    • Click Apply Schedule to confirm the plan, write the simulation requests, and push the development plan to the master database.
