(PetroleoHoje) Petrobras will contract an exclusive 4D seismic campaign with streamer and gravimetric and magnetometric data for the Tartaruga Verde and Tartaruga Verde Sudoeste fields, in the Campos Basin. The company launched a tender for the acquisition of mapping covering an area of 246 km², in water depths from 100 to 1,600 m.
Tender for the 4D seismic acquisition was launched at the end of January, with bid delivery scheduled for February 21. The deadline may be extended by the bidding committee by 20 to 30 days.
In addition to providing the main vessel for registration and source and the secondary vessel – the winning company will also have to provide one or more supply vessel support vessels and a chase vessel. Work will begin 60 days after Petrobras issues the service authorization.
