There are 25 petroleum exploration licences in place. In addition, two applications for licences under the frontier licensing round in the South Porcupine Basin, which closed last December, are being assessed and I expect to make a decision on these in the coming weeks.
Information regarding the various authorisations issued, together with the names and addresses of the companies involved in petroleum exploration in the Irish offshore, is contained in a report prepared by my Department every three months or so. A copy of the latest report is being furnished to the Deputy. I should add that the names of companies exploring for petroleum are a matter of public record. I report the position by way of a half yearly report in respect of each six month period ending 30 June or 31 December, in accordance with the Petroleum and Other Minerals Development Act, 1960. These reports are laid before each House of the Oireachtas and copies are kept in the Oireachtas Library. The most recent report available covers the period 1 July 1998 to 31 December 1998.
There is no company engaged in drilling for hydrocarbons in our continental shelf at present. However, there were important developments last year in relation to two hydrocarbon accumu lations in our offshore, the Corrib gas accumulation and the Helvick oil field. Three other earlier discoveries of some significance were the Connemara oil field, the Seven Heads oil and gas accumulation and the south-west lobe of the Kinsale Head gas field.
In the case of the Corrib, located off the Mayo coast, in 1998 Enterprise Oil and its partners, Saga Petroleum and Statoil Exploration (Ireland) Limited, drilled and tested an appraisal well, flaring gas on a test at a stabilised rate of 63 million cubic feet of gas per day. It is not possible to give precise figures for the size of the gas accumulation at this stage; this will only be possible when the accumulation has been fully evaluated. The evaluation process will involve further appraisal work being carried out over the next two to three years and is expected to include the drilling of additional appraisal wells.
In May last year a ten year petroleum lease was granted to Providence Resources plc, over the Helvic oil field off the Waterford coast. Published figures indicate that it contains an estimated seven million barrels of recoverable oil together with associated gas. Under the terms of the petroleum lease, the company is required to submit a detailed plan of development for the field for my approval by 1 May 2000.
The Connemara oil field, with an estimated 200 million barrels of oil in-place, was appraised in 1997 by Statoil but the results were such that the company concluded that it could not declare the field commercial. The Seven Heads oil and gas accumulation, estimated to have at least 50 million barrels of oil and 100 billion cubic feet of gas in-place, was offered to the industry last year under a lease undertaking round but no applications were received by my Department.
The south-west lobe of the Kinsale Head gas field, estimated to contain some 50 billion cubic feet of gas in-place, is not being drained by the existing production facilities. Marathon, the operator, is currently considering the possibility of a programme of development to bring this into production.
The Government is committed to continuing to promote and encourage, to the fullest extent, hydrocarbon exploration in Irish waters in order to enhance the prospects of further commercial discoveries.
