Maps
In the ThermoGIS Mapviewer, the input, output, and data availability maps can be viewed per aquifer. The table on this page provides an overview of exactly which maps these are, including the unit and a short description.
The following maps can be viewed in the mapviewer for geothermal energy:
| Map | Unit | Description |
|---|---|---|
| Top depth | m | depth of the top of the aquifer |
| Thickness P | m | gross thickness of the aquifer |
| Permeability P | mD | permeability of the net aquifer |
| Net-to-gross | - | net-to-gross ratio of the aquifer |
| Transmissivity P | Dm | product of thickness, net-to-gross and permeability |
| Temperature | °C | temperature at mid aquifer depth |
| Flow rate P,S | m³/hr | production and injection flow rate |
| Power P,S,H | MWth | geothermal power of the doublet |
| Heat in place | GJ/m² | initial heat content of the aquifer |
| Potential recoverable heat | GJ/m² | heat which can be extracted from the reservoir, unconstrained by economic limitations and irrespective of flow properties over the technical lifetime of a doublet (30 years) |
| Technical potential S,H | - | technical potential based on subsurface conditions and doublet parameters |
| Economic potential S,H | - | potential constraint by technical and economic limitations |
| 'White spots' | - | transparency overlay indicating data availability |
| Data availability | - | overview of data availability (seismic data and wells) |

| Net-to-gross G | - | net-to-gross ratio of the aquifer |
| Transmissivity P,G | Dm | product of thickness, net-to-gross and permeability |
| Temperature G | °C | temperature at mid aquifer depth |
| Flow rate P | m³/hr | production and injection flow rate |
| Power P | MWth | geothermal power of the doublet |
| Injected energy in year 15 P | GJ | thermal energy injected in HT-ATES in year 15 |
| Produced energy in year 15 P | GJ | thermal energy produced by HT-ATES in year 15 |
| Terugwinrendement in jaar 15 P | - | = thermal energy produced in year 15 / thermal energy injected in year 15 |
| Economic potential | - | potential based on UTC and a comparisonwith the heat price |
| Data availability | - | overview of data availability (seismic data and wells) |
