Details on boreholes can be found per individual borehole. For a restricted number of datatypes it is also possible to download the complete dataset.
Information on data supply and provision may be found on the data supply page.
Overview
An overview all boreholes can be found using the datacenter
Data by borehole
Administrative data of wells and boreholes are always available in the public domain and information can be obtained by searching for a borehole in the interactive map or using the datacenter.
Well log measurements and reports are available after the confidentiality period of five years has expired.
The following data types are available:
- Administrative data
- Documents: reports and logs (including composite logs, as TIF or PDF format)
- Logs (LIS/LAS): digital log curves
- Samples: explanation of Rock-Eval & Vitrinite reflectance data
- Core measurements
- Lithostratigraphy
- Deviation data
Borehole statuses
| Status | Definition |
| Drilling | This status applies when the borehole is being constructed using a drilling rig. |
| Producing/Injecting | This status applies when a substance is being transported in the borehole. This can be either from the subsurface, to the subsurface, or both simultaneously. |
| Closed-In | This status is assigned to a borehole that is capable of transporting a substance, but where the transport is intentionally paused by closing valves or shutting off pumps. |
| Monitoring | This status applies to a borehole for which the operator has communicated that it is solely set up and used for monitoring subsurface processes. Examples include monitoring subsidence or reservoir pressure. This status will take precedence over the Closed-In status. |
| Sidetracked | This status is assigned to a borehole from which another borehole has been drilled. A condition for this status is that one of the original boreholes does not have the status Plugged and abandoned. When the parent borehole receives the status Plugged and abandoned, that status is also assigned to this borehole. |
| Suspended | This status is assigned when one or more barriers have been placed in the borehole (other than closing valves or shutting off pumps in the status ‘Closed-In’) in anticipation of future operations, such as resuming drilling activities, starting production and/or injection, or completely abandoning the borehole. If another status also applies to the same borehole, that status will be retained. |
| Plugged and abandoned | The status is assigned when a borehole when is sealed and left without the intention of returning, and all operations and activities have ceased. Legally, the status 'Plugged and abandoned' corresponds one-to-one with the legal status ‘Decommissioned', as used in the Mining Regulation (§8.5). Conditions for a decommissioned borehole are described in this section of the law. |
Borehole sample images
Borehole sample images are available for a number of boreholes. These can be viewed by selecting a borehole via the interactive map or the datacenter. and then navigating to the ‘Borehole sample images’ tab.
An overview of all boreholes with borehole sample images can be found on the Core collection page.
Other sources of borehole data
Participation to the Guarantee Scheme for Geothermal Energy requires the release of certain borehole data after completion. This information can be found on the RVO-website.
