MASSY, FranceCGG has completed pre-stack time migration (PSTM) of its 2,500-sq km (965-sq mi) Dunquin multi-client survey, which the company acquired last summer over block 44 of the Porcupine basin offshore western Ireland.

This is the latest in a series of multi-client surveys CGG has acquired in the area, where it now has 10,500 sq km (4,054 sq mi) of 3D and around 2,000 km (1,243 mi) of long-offset 2D broadband data.

The company delivered PSDM products for its 2016 Galway and Cairenn surveys last year. As with these exercises, the Dunquin data will be processed using advanced velocity modeling and depth imaging, following industry funding.

According to CGG, the initial results reveal important details of the carbonate reservoir that forms the Dunquin structure.

Luc Schlumberger, EVP, Multi-Client & New Ventures, CGG, said: “Our new Dunquin data set…will enhance industry understanding of potential areas of interest in this still unexplored region.”
