Permanent Offer | Sharing Rounds

The new Sharing POR targets the presalt and includes blocks that were to be offered in production sharing rounds that were not held, as well as presalt blocks from previous rounds that were not bid on. 

The Santos and Campos basins hold the majority of Brazil’s presalt oil reserves. These complex reservoirs offer the potential for huge rewards, but they require deep pockets and considerable expertise to produce. Since 2016, major oil companies have been invited to take a larger share in the Santos and Campos basins, although Petrobras has preferential bidding rights that guarantee it an operating stake of at least 30%.

In these prolific areas, PGS has over 70 000 sq. km of 3D seismic in its data library. This includes the monumental Santos Vision 3D, with almost 50 000 sq. km of rejuvenated data benefiting from the latest imaging techniques. You can read about the challenges, the technology applied, and the striking results in our Santos Vision case study

Data from PGS’ first Campos Deepwater GeoStreamer X survey provides over 17 000 sq. km of dual azimuth insights inside and outside the presalt polygon. Blocks covered by this survey, Citrino, Larimar, and Onix, have been nominated by PGS. Following CNPE certification, they will be included in future sharing rounds.

The Campos Deepwater project has been extended to the north with Campos Deepwater Vision, a modern broadband reprocessing using our latest VMB and imaging technology that covers the upcoming Larimar block.

Under the second Permanent Offer Sharing Round, announced in August 2023, Brazilian authorities are offering six areas.
