The survey comprises 9,000 km (5,592 mi) of long-offset broadband 2D seismic and will be the first comprehensive well-tie survey covering the Atlantic margin off western Ireland. It will cover the Goban Spur, Porcupine and Slyne basins, and includes well-tie to over 30 exploration wells. The survey also incorporates the Connemara and Burren oil fields and the Spanish Point gas discovery.
Jan Gunnar Opsal, Norway country manager for Searcher Seismic, says that the rift systems associated with these basins are among the most interesting exploration targets in the North Atlantic, with recent drilling results indicating considerable oil potential.
“The Flemish basin on the Canadian side of the Atlantic Rift was located adjacent to the Goban Spur/Southern Porcupine basins until Aptian time, suggesting the possibility that similar play types may be revealed within the Echidna survey area,” he notes.
The Echidna survey will be acquired with a +8-km (+5-mi) streamer, which is longer than most existing surveys.
Standard deliverables for the survey will include both time and depth image processing. The survey also incorporates the historical drilling results in one consistent, long offset broadband seismic dataset.
Acquisition is scheduled to begin in March 2015, with fasttrack data expected in time for evaluation before the Irish bid round.
