Our experience in ultra-deep waters – an environment in which we were the first independent Brazilian company to operate, within the Santos Basin pre-salt exclusion zone – has consolidated our experience and delivery capacity.

We operate the Atlanta Field Block BS-4, located within the Santos Basin, in which we have a 100% stake.

We began production, in 2018, under the SPA (Antecipated Production System), using the FPSO Petrojarl I. More than 25 million barrels have already been produced.

Under the SPA, we drew up a new development plan for the DS, which was operationally more efficient and allowed a significant reduction in investment. The first oil, in Phase 1 of the DS, is expected in mid-2024 and involves 6 horizontal wells, connected to the new FPSO Atlanta, which will have a production capacity of up to 50,000 barrels (bbl)/day and can store up to 1,600,000 barrels (bbl). This will optimize the costs and offloading operations of the oil produced.

Refitting of the new FPSO Atlanta is proceeding at a fast pace at the DryDocks World shipyard, in Dubai.

Oliva and Atlanta NE

Near the Atlanta, we have two other growth opportunities:

The estimated volume of the Oliva field is 348 million barrels of oil, of which approximately 60 million barrels is recoverable. During the 3^rd quarter of 2023, we approved the engineering details and the hiring in 2024 of equipment with a longer delivery time, with a view to the development of the Oliva Field – our plan is to drill two wells in 2025/2026, with the first oil expected in 2027.

We also confirmed in 2023 the existence of oil in a reservoir drilled in the Atlanta field, for which preliminary estimates indicate a volume of 230 million barrels. The drilling of a pilot well confirmed the deposit at a new location, in a reservoir called Atlanta NE.

We have a 45% stake in the Manati field, one of the largest non-associated natural gas fields in Brazil. It is located in the Camamu Basin, off the coast of Bahia state.

Having accumulated almost 15 years of production experience, we see a positive outlook for the gas market, as well as new opportunities for the field. We aim to maximize the use and generation of value from the Manati field.

The Manati wells are connected to the PMNT-1 platform, a fixed production unit installed in 35 m of water, 10 km off the coast from the state capital, Salvador. From there, the gas is channeled through a 36 km pipeline to a pumping station (SCOMP), where it is compressed and travels another 89 km to a processing plant (EVF). The Manati field also produces condensate, as well as gas.

We have acquired a 23% stake in the Abalone, Ostra and Argonauta oil and gas fields, which are part of the Parque das Conchas, located in the Campos Basin – the effective date of the transaction is July 1, 2023.

Production is distributed among 25 producing wells, connected to the FPSO Espírito Santo, which currently produce a combined total of around 35,000 barrels (boe) per day, with an average of 28,000 barrels (boe) per day in the first half of 2023.

This acquisition is aligned with our portfolio strategy, adjusted return on risk, growth opportunities and our seeking of efficiency in capital allocation.

The closing of the transaction is subject to approval by the responsible bodies.

We have acquired a 100% stake in the Uruguá and Tambaú oil and gas fields, located in the Santos Basin.

The transaction includes the gas transportation infrastructure connecting them to the Mexilhão field.

This deal represents a milestone in the company’s business diversification. The location, in the Santos Basin, not far from the Atlanta and Oliva fields, makes it possible to set up an operational cluster and take advantage of synergies.

The Uruguá and Tambaú fields are producing oil and natural gas by means of the FPSO Cidade de Santos, which was purchased by Enauta from Modec.

Over the last five years, the average production has been approximately 7,400 barrels of oil equivalent per day.

The closing of the transactions is subject to the meeting of certain conditions and approval by the responsible bodies.

We have a 100% stake in block FZA-M-90, located in the Foz do Amazonas Basin. The 3D seismic surveys and data processing have already been completed.

Situated in the far northwest of the Brazilian Equatorial Margin, the basin extends across the continental shelf of the states of Pará and Amapá, right up to the border with French Guiana.

It is described by the ANP as a region with potential for gas and light oil discoveries, with indications of hydrocarbons in wells already drilled by the industry in both shallow and deep waters.

We have a 100% stake in two deepwater blocks: PAMA-M-265 and PAMA-M-337. Both blocks have been covered by 3D seismic surveys.

Considered to be a new frontier, the Pará-Maranhão Basin is an entirely offshore basin, situated within the Brazilian Equatorial Margin and covering an area of approximately 48,000 km². It is bounded to the east by the Barreirinhas Basin and to the west by the Foz do Amazonas Basin.

Activities already performed in the region suggest the presence of light oil.

We have a 30% stake in the onshore blocks PAR-T-86, PAR-T-99, PAR-T-196 and PAR-T-215, situated in the states of Mato Grosso do Sul and Goiás, within the Paraná Basin.

In the event of making a discovery, the proximity to the gas consumer market would facilitate the channeling of the natural gas produced. If successful, the consortium shall analyze the possible adoption of the reservoir-to-wire (R2W) model, whereby the gas produced is used to generate electricity, which will contribute to the SIN (Brazilian National Grid), using a nearby transmission line. This model has already been successfully adopted by our partner in other projects.

The Paraná Basin is classified as a new frontier. Favorable aspects that are worth drawing attention to include:

• The region was included in the ANP program for the systematic acquisition of geological data – involving the investment to date of approximately R$200 million.

• Model of expected accumulation similar to that of the Parnaíba Basin, in the Parque dos Gaviões.

• Active and proven oil-bearing systems.

• Strategic geographical location.

Characteristics: good infrastructure, market and logistics facilities and expectation of natural gas supplies.

We have a 30% stake in blocks SEAL-M-351, SEAL-M-428, SEAL-M-430, SEAL-M-501, SEAL-M-503, SEAL-M-505, SEAL-M-573, SEAL -M-575 and SEAL-M-637.

In March 2022, our consortium drilled the first well in the region, in the Cutthroat prospect, located in Block SEAL–M-428.

The consortium will also carry out complementary studies, integrating the sample data with its regional geological interpretation, in order to update the basis for evaluating the exploration potential of the blocks.

The Sergipe-Alagoas Basin lies onshore, on the edge of the northeastern region of Brazil, including parts of the states of Sergipe and Alagoas and a small portion of Pernambuco state.
