Drilling Contract

Island Oil and Gas PLC 11 April 2006 11 April 2006 ISLAND OIL & GAS EXECUTES DRILLING CONTRACT FOR MULTI-WELL DRILLING PROGRAMME IN 2007 Island Oil & Gas plc, ('Island'), the technology-led exploration and production company, today announces that it has executed a further drilling contract with Petrolia Drilling Limited for the provision of the semi-submersible drilling unit 'Petrolia' in 2007. The contract is for a 150 day drilling programme. It is currently anticipated that the 2007 drilling programme will be primarily focused along the Atlantic Margin off the west coast of Ireland, subject to the necessary regulatory consents being granted. The remainder of the programme remains flexible in order to allow for possible appraisal drilling based on a potentially successful outcome to our 2006 drilling campaign. In addition, Island is reviewing the opportunity to progress potential new international ventures in Northwest Europe and North Africa, which are currently being evaluated. Further details in relation to the 2007 drilling programme will be announced in the coming months. Commenting on the execution of the drilling contract Paul Griffiths, Chief Executive of Island, stated: 'The execution of the new drilling contract cements the very constructive working relationship that we have developed with Petrolia Drilling Limited. It allows us to benefit fully from the huge amount of work that our highly experienced in-house drilling team, under the guidance of Andrew J. McHardy, Island's Drilling Project Manager, has put in to assist in preparing the rig for mobilization for operations in Ireland in coming weeks, subject to the necessary regulatory consents being granted. The 2007 drilling programme provides Island with an opportunity to evaluate its existing prospects, and potential future prospects, along the Atlantic Margin offshore Ireland and, importantly, to potentially develop an international spread of exploration and appraisal drilling projects. Rig availability, in a tight market, gives us significant leverage to use to attract new potential partners to our extensive portfolio of mature exploration projects at a time when quality, high risk/high reward exploration targets are in short supply and rig availability is limited.'
