Ireland: CGG completes Cairenn survey data processing

French geophysical services company CGG has completed the pre-stack depth migration (PSDM) of its Cairenn multi-client survey in the Porcupine Basin, offshore Ireland.

CGG said on Monday that Cairenn was the first in a series of multi-client surveys that CGG was acquiring in the area. PSDM products for its Galway survey will be delivered before the end of the year.

The data sets from both surveys have been processed through an advanced velocity modeling and depth imaging sequence including multi-layer tomography and full-waveform inversion.

CGG described the results as “outstanding” and having “exceptional clarity and deep imaging quality, from the Triassic/Jurassic fault blocks, through the Cretaceous section, and up to the Cenozoic reservoirs.”

Also, fast-track results from additional surveys in the area acquired in 2017 have already been delivered, with final PSDM products due in the second quarter of 2018.

Jean-Georges Malcor, CEO of CGG, said: “These new datasets deliver high-quality coverage west of Ireland, enhancing industry understanding and mapping of the multiple hydrocarbon plays being chased in this promising region.”

In related news, the French company won a contract last week with the Ivory Coast’s Direction Générale des Hydrocarbures (DGH) and PETROCI, the national oil company, for an onshore and offshore survey in the African country.
