Brazil’s Búzios field sets new monthly and daily natural gas export records in July and August 2026

Brazil’s Búzios field, operated by Petrobras in the pre-salt offshore, crossed a milestone it had never reached before: in July 2026, the field averaged 381.4 million cubic feet per day (MMcf/d) of natural gas exports — the first time it surpassed 353 million cubic feet per day (MMcf/d) in a single month. The record didn’t hold for long.

On August 6, 2026, Búzios set a new daily peak of 497.9 million cubic feet per day (MMcf/d), edging past the 490.9 million cubic feet per day (MMcf/d) mark registered just weeks earlier in July.

Búzios breaks monthly and daily gas export thresholds

Two records in two months. The numbers are hard to ignore.

After the membrane replacement, that figure rose to approximately 106 million cubic feet per day (MMcf/d) per platform — a doubling of individual unit capacity.

The July 2026 monthly average of 381.4 million cubic feet per day (MMcf/d) didn’t just beat the previous record — it blew past it. The prior benchmark was 321.4 million cubic feet per day (MMcf/d), set in March 2026, which means a jump of nearly 19% in four months. Then, before July was even fully digested, August 6 produced a single-day peak of 497.9 million cubic feet per day (MMcf/d), topping the 490.9 million cubic feet per day (MMcf/d) mark from the month before.

It’s the first time in the field’s history that average monthly exports crossed the 353 million cubic feet per day (MMcf/d) threshold — not a small footnote, but a structural shift in what Búzios actually delivers.

Búzios is already one of Brazil’s largest oil and gas producing assets. The pre-salt field sits in deep offshore water, and its production profile has been climbing steadily for years. These latest records confirm the growth isn’t slowing.

Platform optimization, not new units, drove the gains

Here’s what makes the records more interesting: no new platforms came online to produce them.

The performance gains came entirely from optimizing existing infrastructure. The main driver was a modernization program targeting the gas treatment plants on four platforms — P-74, P-75, P-76, and P-77 — specifically the replacement of CO2 removal membranes, a technically precise intervention that turned out to have an outsized operational impact.

Before the upgrade, each of those platforms exported roughly 53 million cubic feet per day (MMcf/d) of natural gas. After the membrane replacement, that figure rose to approximately 106 million cubic feet per day (MMcf/d) per platform — a doubling of individual unit capacity. Petrobras has indicated there’s still room to push higher once further process adjustments are completed.

The program started in 2025 and is now in its final implementation phase. The FPSO Almirante Barroso also contributed to the improved output figures. Extracting more from existing assets rather than waiting on new ones shortens the timeline for results and sidesteps the delays that typically accompany commissioning new production systems.

Growth trajectory since 2024 and planned expansion through 2032

The scale of Búzios’s transformation over two years comes into sharp relief when you look at the baseline.

In July 2024, the field averaged just 166 million cubic feet per day (MMcf/d) of daily gas exports. By July 2026, that figure had reached 381.4 million cubic feet per day (MMcf/d) — more than double in 24 months. That kind of growth rate is unusual for a mature offshore field operating without a major wave of new platform additions.

The commissioning of Route 3 and a series of additional projects since 2024 sustained that upward curve. The optimization program on P-74 through P-77 then accelerated it. Together, they’ve repositioned Búzios as a serious gas supplier, not just an oil asset with associated gas on the side.

The expansion isn’t finished. Platforms P-78 and P-79 are planned to come online by 2027, adding capacity on top of what existing units now deliver. The full development plan calls for 12 platforms in total, with 8 eventually carrying gas export capacity. The final piece of that buildout is the Búzios 12 unit, scheduled to begin operations in 2032, carrying an estimated export capacity of 194.2 million cubic feet per day (MMcf/d) — roughly half of what the entire field averaged in July 2026.

Petrobras links production investment to domestic gas price reduction

The records arrived alongside a pointed policy statement from Petrobras president Magda Chambriard.

“Petrobras has repeatedly invested in increasing the country’s gas production, and these investments are the only ones capable of reducing the price of gas,” Chambriard said. The argument is direct: supply drives price, and supply comes from capital investment in upstream capacity.

Chambriard also addressed the debate around ownership structures in Brazil’s gas sector, arguing that transferring ownership of the gas company wouldn’t lower prices without a corresponding increase in supply. In her framing, who controls distribution matters far less than whether more gas is actually being produced.

Petrobras is using the Búzios results as evidence for that position — framing the field’s records as proof that consistent upstream investment, rather than regulatory restructuring, is what builds domestic supply.

Doubled gas exports

Búzios set two records in rapid succession: a monthly average of 381.4 million cubic feet per day (MMcf/d) in July 2026, up from the previous high of 321.4 million cubic feet per day (MMcf/d), and a daily peak of 497.9 million cubic feet per day (MMcf/d) on August 6. Both milestones came through optimization of existing platforms — specifically membrane upgrades on P-74 through P-77 — rather than new production systems. The field has more than doubled its gas exports since July 2024. Further capacity additions are planned through 2027, with the full development program extending to 2032. Petrobras frames the results as a direct case for investment-led supply growth as the path to lower domestic gas prices.
