HOUSTON, Jan. 25 -- An exploration well operated by Marathon Oil UK Ltd. in the St. George's Channel basin between Wales and Ireland failed to find hydrocarbons.
The 103/1-2 well sought to appraise Marathon's 1994 Dragon discovery, which found gas and liquid hydrocarbons in Jurassic formations below 7,500 ft (OGJ, Nov. 7, 1994, p. 35).
Marathon has not released technical data on the latest well. The discovery well is in 318 ft of water 24 miles off Wales, 26 miles off Ireland, and 100 miles northeast of Kinsale Head and Ballycotton gas fields off southern Ireland.
The discovery well found 80 bcf of gas, whereas the commercial threshold for development and a pipeline is 250 bcf, press reports said.
Marathon averaged a net 58 MMcfd in Ireland in 2004.
