f A Structural History of the Rockall Trough, West of Britain

The Rockall Trough is a deep water frontier basin (up to 2000 m) west of Britain and Ireland which is approximately 300 km wide and 1500 km long. It contains a significant portion of unlicensed acreage that may become available in future UK and Irish licensing rounds. We present the interpretation of the structural and stratigraphic history of the Rockall Trough resulting from an extensive exploration programme of the eastern margin. The interpretation incorporates information from three of the four wildcat wells drilled in the basin (all unreleased) and over 20,000 km of seismic data lied to potential fields data and placed into a plate tectonic framework.
