In order to promote and assist effective petroleum exploration, we make available a range of technical information, obtained under authorisations issued by us, as soon as the confidentiality period has expired.  Further information regarding data confidentiality can be found in our Licensing Terms for Offshore Oil and Gas Exploration, Development and Production.  In June 2014 the confidentiality period for all new speculative and multi seismic data acquired in the entire Irish offshore area was increased to 10 years.

The Department engages specific Data Agents to prepare, manage, market and license exploration data. As of 1st January 2018 data can be obtained from the following companies:
