Furthermore, State Supervision of Mines has drawn up a timetable (Only available in Dutch) to show the chronological sequence in the installation and exploitation of a geothermal doublet and is about to publish a presentation explaining the various steps:

1. Application for an exploration permit

  • Submission of an action plan
  • Geological quickscan


2. Exploration permit (before the drilling process)

  • Detailed geological research (determining the optimal location and the reservoir characteristics)
  • Interference with hydrocarbons?
  • Causes of seismicity and subsidence?
  • Feasibility study (financial)


3. Exploration permit (the drilling process)

  • Submission of drilling scheme
  • Setting up the drilling location
  • Drilling and testing the geothermal doublet
  • Submission of daily drilling reports, log data and well test data


4. Application for a production permit

  • Submission of application for a production permit and of a production plan
