Paris-based CGG has completed a huge 3D seismic data shoot over four frontier blocks located east of Sao Tome & Principe that are operated by Lisbon-based Galp Energia and US player Kosmos Energy, writes Iain Esau.
Joao Casacao, a petroleum geologist at Galp, said the “last shot” of the 16,000 square kilometre survey took place on 20 August.
CGG’s Oceanic Endeavour vessel began the survey work in February this year.
