Marathon International Petroleum Ireland and Marathon International Petroleum Hibernia Limited are subsidiaries of Marathon Oil Company, which has been operating in Ireland since 1961 and currently employs around 60 people in Ireland. Marathon is a leading explorer in Irish offshore waters and has drilled or been involved in the drilling of 66 of the more than 150 exploration wells drilled both onshore and offshore. Marathon was the first and to date the only company to have discovered and produced natural gas in commercial quantities from the Irish offshore. To date, the company has developed three natural gas bearing reservoirs in the Celtic Sea. The Kinsale Head Gas Field was the first to be developed and is by far the largest of the three reservoirs. It was discovered in 1971 and contained about 1.8 trillion cubic feet of natural gas. The smaller Ballycotton Gas Field (60 billion cubic feet) and Southwest Kinsale Gas Field (30 billion cubic feet) were discovered in 1989 and 1995 respectively. The reservoirs are all located at a depth of approximately 900 metres (3,000 feet) below the seabed. In addition to its sole ownership of the three Kinsale area reservoirs and associated facilities, Marathon also owns 18.5 per cent of the Corrib Gas Field located off the Mavo coast.
