Time-Dependent Well Events and Schedule Data Generation

[magnesj]

Description

Currently, ResInsight lacks support for modeling changes in perforation intervals, valves, or well production control during the setup phase. This feature request proposes a mechanism to define a timeline of events via a text configuration file. These events will drive the generation of schedule data (e.g., WELSEGS, COMPDAT, WCONPROD) for simulations.

Proposed Workflow

The suggested workflow for generating schedule data from an event file is as follows:

1. Import a grid with grid cell properties.
2. Import well trajectories.
3. Use Python scripting to parse events and generate the schedule:

   # Example API usage
   event_data_as_text = read_event_file("well_events.txt")
   schedule_data = resinsight.create_schedule_data(event_data_as_text)

4. The resulting schedule_data structure will contain completion data and production controls indexed by date, ready to be exported to a simulation schedule file.

Event File Format Specification

The input text file defines events occurring at specific time steps. Events are grouped by well sections.

Event Types (Prioritized)

1. Perforation intervals
2. Well production control
3. Valves
