3D seismic Survey

This Dataset contains a GIS Vector polygons of 44 3D seismic survey areas underaken in seas around Ireland. Data includes contractor, line, survey Id, company, vessel, survey area name, project code and prefix details. The data has been collected in seas around Ireland including the North Atlantic Ocean, Irish Sea, Saint George &s Channel and Celtic Sea. The data has been collected for the period 1982-2014. The imaging deficiencies of 2D seismic profiling were remedied by the implementation of 3D seismic data acquisition, which allows data processing to Migrate reflections to correct their image coordinates in 3D space. Seismic surveys are used to produce detailed images of local geology to determine the location and size of possible oil and gas reservoirs. Data has been collated by the Petroleum Affairs Division as part of its role to maximise the benefits to the Irish State from exploration for and production (E and P) of indigenous oil and gas resources. The Dataset is considered an accurate recorded representation of 3D seismic surveys completed and Logged by the Petroleum Affairs Division.
