New west coast gas licences

Providence Resources PLC 09 December 2004 PROVIDENCE SECURES NEW WEST COAST GAS LICENCES Providence Resources P.l.c. is today (Thursday, 9th December 2004) pleased to announce that the Minister for Communications, Marine and Natural Resources, Noel Dempsey T.D., has granted two new Frontier Exploration Licences in the Porcupine Basin off the west coast of Ireland. The licences have been granted to Providence (80%, Operator) and Sosina Exploration Limited (a UK registered oil and gas exploration company) for a term of up to 16 years. The agreed work programme comprises a review and reprocessing of existing subsurface data which will be primarily carried out by Sosina. The first of these new Frontier Exploration Licences contains two exciting discoveries - a large gas condensate field known as 'Spanish Point' (IRL35/8-2), as well as a tested oil discovery known as 'Burren' (IRL35/8-1). The 'Spanish Point' discovery was made by Phillips Petroleum in 1981. Post-well analysis by Phillips indicated that the structure could contain up to 1.1 TCF (Trillion Cubic Feet) of gas and 112 MMBO (Millions of Barrels of Oil) recoverable. At that time these potential reserves were considered to be uneconomic due a combination of low oil/gas prices, lack of appropriate extraction technologies together with remoteness from gas infrastructure. New technologies such as GTL (Gas to Liquids) together with increased gas prices in Ireland now suggest that the 'Spanish Point' field is worth re-evaluating for a possible commercial development. In addition the nearby 'Burren' oil discovery, which has significant upside potential, may provide a future satellite tieback opportunity. The second licence is located in the South Porcupine Basin and contains a super-giant deepwater exploration target termed 'Dunquin'. The presence of hydrocarbons at 'Dunquin' has been indicated both directly from seismic acquired over the prospect as well as from seabed gravity cores overlying the structure. Providence/Sosina are also commencing a methane gas hydrates study, to assess the potential occurrence of methane gas hydrates in the deep waters off the west coast of Ireland. This study will be carried out in close association with, and as part of, the Irish Petroleum Infrastructure Programme (PIP-PEPPS) together with the National University of Ireland Galway (NUIG) and the US-based firm Hydrates Energy International (HEI). The group will utilise data from the Irish National Seabed Survey and will work closely with The Geological Survey of Ireland in this regard. Providence/Sosina believe that GTL technology, which may be brought to bear on the 'Spanish Point' development, may also be applicable to the future economic extraction of potential methane gas hydrate reserves offshore Ireland in the form of a 'clean' low emission energy source. Commenting on the licence award, Company Chairman, Dr. Brian Hillery said: 'We are delighted to have secured these highly prospective licences in an area of increased oil and gas exploration and development activity. We look forward to working with our partner Sosina in evaluating the potential that these blocks afford and to ultimately progressing them towards drilling'. Ends.

'DUNQUIN' PROSPECT Whilst lying in the deeper waters of the South Porcupine Basin (1,600 metres), the 'Dunquin' prospect provides a world-class high risk/high reward exploration opportunity. The 'Dunquin' prospect covers some 175,000 acres in Quadrant 44 (Kinsale Head is -25,000 acres) and which provides very considerable upside potential. Previously licensed by Elf up to 2003, the blocks were subsequently relinquished following Elf's merger with TotalFina, though their work, which has since been published, supports the presence of a major Lower Cretaceous reef system in the blocks. This type of hydrocarbon play is directly analogous to the Golden Lane fields in Mexico (-5 Billion barrels of recoverable reserves). In addition, TotalFinaElf noted the presence of both direct hydrocarbon indicators in the seismic data together with hydrocarbon shows in gravity cores taken in the seabed overlying the prospect. Providence/Sosina is planning to deploy new cutting edge geophysical technologies such as CSEM (Controlled Source Electro-Magnetics), which have been pioneered with great success on deepwater prospects off West Africa, in order to further progress this vast potential resource towards drilling. TECHNOLOGY Providence/Sosina will primarily focus on the assessment and deployment of modern extraction technologies such as horizontal drilling and FPSO (Floating Production Storage & Offloading) platforms in tandem with emerging process technologies such as Gas to Liquids (GTL), in order to unlock the value in the 'Spanish Point' field. GTL technology, which allows for the transformation of methane gas into a 'clean' low emission diesel fuel, is presently seeing very significant global investment by the oil and gas exploration and production industry. METHANE GAS HYDRATES Gas Hydrates are non-stoichiometric crystalline compounds that belong to the inclusion group known as Clathrates. Hydrates occur when water molecules attach themselves through hydrogen bonding and form cavities which can be occupied by a single gas or volatile liquid molecule. These naturally occurring hydrates containing mainly methane exist in vast quantities within and below the permafrost zone and in subsea-sediments, wherever suitable pressure-temperature conditions occur. Methane hydrate is found replacing fluid in sediment pore spaces. Permafrost hydrates are restricted to Polar areas, mainly on land, and associated with conventional gas and petroleum deposits. Oceanic hydrates, which appear to contain much more methane than permafrost hydrates, are mainly developed in marine sediments on continental slopes at water depths exceeding - 500m. Concentrations of gas hydrate (a solid ore of methane) can be characterized as shallowly buried strata bound mineral deposits, from which methane gas must be derived in-situ and then recovered to the surface. Estimates of the volume of methane in gas hydrate worldwide are firming up at about twice the mass of carbon held in all conventional gas, oil, and coal deposits combined. HYDRATES ENERGY INTERNATIONAL Hydrates Energy International is a new company dedicated to research and development in the field of natural gas hydrate. The principal gas hydrate issues that are the focus of HEI are: 1. Research and development activities leading to commercial extraction of natural gas from gas hydrate. 2. The effect of hydrate on drilling safety and seafloor stability. HEI delivers special expertise in a broad range of seafloor studies bearing on natural gas and gas hydrates including the design, commissioning and interpretation of seismic and other acoustic surveys, optimization of research and work programs for gas hydrates, modeling of potential gas hydrate concentrations and the development of integrated hydrate studies. IRISH NATIONAL SEABED SURVEY The Irish National Seabed Survey (INSS) encompasses an area that is approximately ten times the size of Ireland's land area and represents one of the largest seabed mapping projects undertaken anywhere in the world. The project is managed by The Geological Survey of Ireland in co-operation with the Marine Institute. The INSS is primarily about acquiring baseline information (multi-beam sonar) to promote and encourage research in marine science. This acoustic technique is providing detailed bathymetry (water depth) data and knowledge of the nature of the seabed and its overlying sediment. Magnetic and gravity techniques are helping to evaluate the nature and structure of the deeper geology. Other survey techniques are also being used to acquire additional primary datasets including: single beam echo sounder ,sub-bottom profiler (shallow seismic),water column measures of salinity, conductivity, temperature and speed of sound profiles ,seabed ground-truthing and sidescan sonar. GAS TO LIQUIDS (GTL) Gas to Liquids is a term encompassing a number of processes, whereby, gas previously without a market can be exploited as a liquid thus creating commercial value. Around the world there are substantial volumes of gas, often associated with the production of oil from offshore fields, that are either flared, re-injected or remain unused because of the lack of ways to bring the gas to market. Up to 30% of the worlds discovered gas can be considered stranded. Natural gas can be used to produce bulk petrochemicals, including methanol and ammonia, but these are relatively small users of the gas reserves with limited markets. Liquid and other petroleum products are cheaper to transport, market and distribute to large markets. These can be moved in existing pipelines or products tankers and even blended with existing crude oil or product streams. Additionally, no special contractual arrangements are required for their sale with many suitable domestic and foreign markets. New technology is being developed and applied to convert natural gas to liquids in gas to liquids technology (GTL). The projects are scalable, allowing design optimisation and application to smaller gas deposits. GTL not only adds value, but capable of producing products that could be sold or blended into refinery stock as superior products with less pollutants for which there is growing demand. Reflecting its origins as a gas, gas to liquids processes produces diesel fuel with an energy density comparable to conventional diesel, but with a higher cetane number permitting a superior performance engine design. Another 'problem' emission associated with diesel fuel is particulate matter, which is composed of unburnt carbon and aromatics, and compounds of sulfur. Low sulfur content, leads to significant reductions in particulate matter that is generated during combustion, and the low aromatic content reduces the toxicity of the particulate matter reflecting in a worldwide trend towards the reduction of sulfur and aromatics in fuel.
