493 Deputy Jan O’Sullivan asked the Minister for Communications, Energy and Natural Resources if his Department has an inventory of all known oil and gas fields, both on and off-shore, on Irish territory; if he will supply this information, including the exploration rights that are in place for any of these fields; and if he will make a statement on the matter. [36001/10]

There have been a number of discoveries of oil and gas in the Irish Offshore in recent years, however none of these has been declared commercial to date. The only recent petroleum discovery that has been declared commercial but has yet to go into production is the Corrib Gas Field.

The following table details all significant hydrocarbon discoveries on and off-shore Ireland. The table includes details of petroleum authorisations currently in place along with details of the original discovery authorisation. Full details of petroleum authorisations are published on the Department's website on a regular basis.
