In November 2019, the ANP nominated three blocks for inclusion in the ANP Production Sharing Round 7 for the pre-salt polygon planned for 2020. The offered blocks are Agata, Esmeralda and Agua Marinha and they have been assessed to have to have a cumulative estimated oil in place of 9.38 billion barrels, according to an ANP technical note. In comparison the five blocks from ANP Production Sharing Round 6, Bumerangue, Cruzeiro do Sul, Aram, Norte de Brava and Sudoeste de Sagitario had an average estimated oil in place of 42 billion barrels. The Agata Block is in the central-eastern part of the Santos Basin, in water depths over 2,000m. It is northeast of BP's Pau Brasil Block and southwest of Chevron's Saturno Block and east of the Petrobras Jupiter Field on BM-S-24. It is still in an ultra-deepwater frontier area of the pre-salt play lacking well control data. Drilling in newly acquired blocks near Agata will begin in 2020 and could provide well data to de-risk the commercial potential of the block. It has two mapped structures called Agata and Agata C and the chance of geological success from drilling the structures is estimated at 21% and 23%, respectively. The average oil in place estimated for the Agata structures was 3.19 Bbo. The Esmeralda Block is in the southwest Santos Basin with water depths from 2,000 to 2,500m. The block is about 50 km southwest of the Equinor's developing Carcara Field on Block BM-S-8 and south of the Aram Block recently claimed by Petrobras in Production Sharing Round 6. A successful pre-salt well was drilled on the block in 2009 by Petrobras but it was ultimately plugged and abandoned and later the block was relinquished. Other exploratory wells are more than 40km away, making it difficult to estimate the size of the pre-salt carbonate reservoirs. The Esmeralda Block has two prospects identified called Esmeralda and Tupa, which are projected to have a 24% and 16% chance of geological success, respectively. The oil in place estimate of the two structures is 5.51 Bbo. The aqua Marinha is in the central ??Campos Basin in a water depth of about 2,000m. It is east of the Petrobras Espadarte Field and south of the Caratinga and Marlim Sul fields and north of the C-M-539 Block which holds the Equinor developing prospects of Gavea, Seat and Pao de Acucar. Three possible pre-salt structures were identified with chances of geological success of 47%, 31% and 47% and a combined oil in place estimated to be 680 MMbo. The ANP has also nominated four blocks for ANP Production Sharing Round 8 planned for 2021. These blocks are the Tupinamba, Jade and Ametista blocks in the Santos Basin and the Turmalina Block in the Campos Basin.
