CGG delivers final PSTM products for Dunquin multi-client survey, west of Ireland


PARIS -- CGG has completed the Pre-Stack Time Migration (PSTM) of its 2,500-km2 Dunquin multi-client survey acquired in Block 44 of the Porcupine basin, west of Ireland, in 2017. Dunquin is the latest in a series of multi-client surveys that CGG has recently been acquiring in the area, totaling 10,500 km2 of 3D and around 2,000 km of long-offset 2D broadband data. PSDM products for its 2016 Galway and Cairenn surveys were delivered last year.

Similar to CGG's Galway and Caireen surveys, the Dunquin data will be processed through advanced velocity modeling and depth imaging, following industry funding. Initial FWI results reveal important details of the carbonate reservoir that forms the Dunquin structure.
