PARIS – Acquisition is underway on CGGVeritas’ 3D multi-client seismic survey in the Central North Sea.

The Quad 29 Phase 1 covers 2,100 sq km and is using the Oceanic Challenger with a 10 x 75 x 6,000 m long-offset configuration.

This is CGG’s first such program using BroadSeis. Trials in the North Sea showed the BroadSeis provided enrichment of detail visible in the seismic data to enhance fault mapping, lithology discrimination, and stratigraphic feature interpretation, says CGGVeritas.

The company expects the survey to image thinner, more complex reservoirs in the deep Carboniferous-Permian through the Jurassic, and up to the Paleogene, and is looking for bypassed hydrocarbons, says CGGVeritas.
