Norway’s Shearwater GeoServices has been awarded a pair of contracts from Petrobras to carry out 4D seismic surveys in the prolific Campos basin offshore Brazil.

Upstream has previously reported that Shearwater submitted the lowest commercial bids in Petrobras’ tenders for the contracting of seismic campaigns covering the Tartaruga Verde and Parque das Baleias fields.

Shearwater said the contract for Parque das Baleias is for the 4D monitoring of the Jubarte and Baleia Ana fields, with work expected to begin in the third quarter of 2023.

Petrobras intends to deploy the Maria Quiteria floating production, storage and offloading vessel in the area where Shearwater will carry out the seismic programme next year.

Shearwater added the second contract covers the acquisition of a high-resolution baseline 4D survey, together with gravity and magnetic measurements, over Tartaruga Verde. The job is scheduled for 2024.

“Shearwater has a strong track record in Brazil and a well-established relationship with Petrobras. We look forward to applying our leading time-lapse geophysical survey capabilities to these large projects,” Shearwater chief executive Irene Waage Basili said.

The company did not disclose the value of the contracts but based on offers submitted in the tenders, the combined deals are worth close to $100 million.
