CGG delivers final PSTM for Dunquin survey off Ireland

French geophysical player CGG has delivered the final PSTM products for the Dunquin multi-client survey in the Porcupine Basin offshore Ireland.

CGG said on Thursday that it completed the pre-stack time migration (PSTM) of its 2,500-square-kilometer 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 square kilometers of 3D and around 2,000 kilometers 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. According to the company, the initial FWI results reveal important details of the carbonate reservoir that forms the Dunquin structure.

Luc Schlumberger, EVP of multi-client and new ventures at CGG, said: “Our new Dunquin dataset adds to our high-quality coverage west of Ireland, shedding new light on the characteristics of known and undrilled structures. It will enhance industry understanding of potential areas of interest in this still unexplored region.”
