Exploration Well Completed

Regal Petroleum PLC 28 November 2005 Immediate Release 28 November 2005 Regal Petroleum Plc ('Regal' or the 'Company') Romanian Exploration Well Completed The Directors of Regal announce that the Company's exploration well (RSD-1) in its Suceava licence reached a total depth of 1248 metres but failed to encounter commercial quantities of hydrocarbons. The well is being plugged and abandoned. A comprehensive suite of advanced wireline log data has been acquired and the well has been completed ahead of time and under budget. Exploration Director Richard Hardman said 'The Suceava Block, located on the Moldavia Platform, is a 4,103 square kilometre exploration, development and production licence area (equivalent to 20 North Sea blocks). This region contains several large commercial gas and condensate fields. Whilst our first well, SE-1, flowed gas from relatively thin sands, our second, RSD-1, has encountered a number of good quality sands'. He went on to say 'Whilst the result of this exploration well is disappointing, we have acquired a large quantity of high quality and useful technical data which is a prerequisite to a proper understanding of the block and the whole region. This technical data will be utilised in our continuing exploration programme in 2006, including the drilling of further wells. We remain confident that this block has the potential to yield commercial reserves'.
