|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.
As of September 1st 2016 the NLOG site is going to change.
The website will still be accessible through the url www.nlog.nl. However internal links to NLOG will change as of this date, we kindly request you take note of this.
The largest changes will be in the arrangement of the pages, a new look and feel of the website and a revised version of the interactive map. Also the revision comprises some minor changes in the static content. The functionality of dynamic features (e.g. the search options in the interactive maps and the selection screens) will be the same as the old site. Some additional functionalities such as a search button and GIS web based services will be added.
Please forward this message to any other interested parties. Should you have any questions please contact firstname.lastname@example.org
We keep this site continually up-to-date. Click here for an overview of recent changes.
