Abstract

Phase 3 of a major Statoil-funded, behind-outcrop coring project in the Upper Carboniferous Clare Basin, western Ireland is currently underway. Earlier drilling has targeted the upper and lower parts of the Ross Formation, a 500 m thick succession of basin-floor sandstones that have high value as a subsurface training and reservoir analogue resource. Initial drilling has focused on the Loop Head area in west Clare where the deep-water deposits are particularly well exposed in high cliffs and where the emphasis has been on building a better understanding of the vertical succession and the high-frequency cycles that characterise this 'ice-house' fan system. Most recent new research cores have been acquired from Ballybunion in North Kerry and the inner Shannon area and these will help constrain down-dip facies changes and the relationship between the basin floor sand system and lateral slopes.
