|This site provides information about oil, gas and geothermal energy exploration and production in the Netherlands and the Dutch sector of the North Sea continental shelf.
It aims to help users access information furnished by the Dutch government in an easy, comprehensible fashion.
This site was produced at the request of the Dutch Ministry of Economic Affairs and is being managed by TNO, Geological Survey of the Netherlands.
Maintenance of NLOG is scheduled from Wednesday 1 June 20:00 till 24:00. In this period the connection with NLOG will be interrupted.
We keep this site continually up-to-date. Click here for an overview of recent changes.
