Offshore Brazil’s Open Acreage Permanent Offer Bid Rounds

Home Seismic Multi-Client Hotspots Brazil Pre-Salt Basins OPP Bid Rounds

With over 965,000 kilometers in 2D multi-client data and 590,000 square kilometers in 3D multi-client data in Brazil, our seismic data covers every basin, sector and block offshore Brazil in the upcoming bid round cycles.

Brazil’s Open Acreage Permanent Offer (OPP)

The Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) plans to launch the fourth Open Acreage Permanent Offer (OPP) cycle under the Production Sharing Regime in 2026. The cycle offers key investment opportunities in Brazil’s oil and gas sector  within the pre-salt polygon.

The Open Acreage Permanent Offer (OPP) allows year-round bidding on exploratory blocks and returned fields, replacing fixed rounds. This flexible model aims to boost investment and speed Brazil’s oil and gas development. Under the Production Sharing Regime, OPP targets pre-salt and strategic areas. These areas are only included in the offer after specific authorization from the National Energy Policy Council (CNPE), ensuring that the most valuable and technically challenging blocks are managed with high regulatory standards.

Santos Basin

There are 15 blocks in the Santos Basin that will be included in the bid round: Jade, Agata, Opala, Quartzo, Rubi, Granada, Cruzeiro do Sul, Calcedonia, Safira Leste, Safira Oeste, Amazonita, Cerussita, Rodocrosita, Aragonita, and Malaquita.

TGS’s Picanha 3D and Santos Vision 3D datasets offer detailed subsurface insights to identify opportunities and reduce risk in this prolific basin.

Campos Basin

There are 8 blocks in the Campos Basin that will be included in the upcoming licensing cycle: Siderita, Hematita, Magnetita, Turmalina, Larimar, Onix, Azurita, and Calcita. 

TGS offers recent 3D seismic and reprocessed data covering all of these areas. Notably, our Campos 3DMC, Campos Deepwater 3DMC, and the reprocessed Picanha 3DMC datasets stand out as key exploration tools for industry.
