Guyana's offshore oil production rose to approximately 885,600 barrels per day in July, according to government data, marking the first monthly increase after four consecutive months of falling output. The 1.9 per cent gain over June brings a pause to a decline that had reduced daily production from a record 918,000 barrels in February to 869,000 barrels by June.

The recovery arrives as the South American nation approaches a long-anticipated production milestone. Guyana has built its entire oil industry around the Stabroek Block, operated by ExxonMobil with Chevron and China's CNOOC holding minority stakes, since first oil was struck there in December 2019. Output has since grown from nothing to levels that place Guyana among the world's fastest-expanding crude producers.

The four-month decline that preceded July's rebound stemmed largely from natural pressure loss at Liza 1, the block's oldest development. That project has produced below its earlier averages as the reservoir matures, a pattern common to offshore fields several years into extraction. Newer developments, including Liza 2, Payara and Yellowtail, had been running above their original nameplate capacities following optimisation work, but this was not enough to offset Liza 1's decline through the spring and early summer.

July's increase suggests some of that pressure has eased, or that operational adjustments across the four producing vessels have restored a portion of the lost volume. The full breakdown by individual project has not yet been published, so it remains unclear whether the gain reflects a broad recovery or improvements concentrated at one or two sites.

The timing matters. Guyana's fifth production vessel, the Errea Wittu, arrived offshore in late August to begin work on the Uaru project, a $12.7 billion development expected to add up to 250,000 barrels per day once it reaches capacity. The Guyanese government has floated a September start date for Uaru, though ExxonMobil has consistently pointed to the fourth quarter of this year. Either way, national output is expected to cross one million barrels per day for the first time once the new vessel ramps up, a threshold that would place Guyana ahead of Venezuela as South America's second-largest oil producer, trailing only Brazil.

For a country of fewer than 900,000 people, the scale of this expansion has reshaped the economy. Petroleum revenues brought in close to $2 billion during the first half of 2026 alone, flowing into the country's Natural Resource Fund through a combination of profit-oil payments and royalties. The finance ministry has projected total oil earnings approaching $2.8 billion for the year.

Whether July's rebound signals a durable stabilisation or a temporary pause before further softening will depend largely on how quickly the ageing Liza 1 field continues to decline, and how effectively output from the newer projects can compensate. Analysts tracking the Stabroek Block have noted that production swings of this size, a few percentage points month to month, are not unusual given the complexity of managing several floating production vessels simultaneously.

What is clearer is the trajectory beyond the immediate figures. With Uaru approaching start-up and a further project, Whiptail, expected to add capacity in 2027, Guyana's production curve points firmly upward over the medium term. Some forecasts put the country's output as high as 1.9 million barrels per day by 2030, a level that would cement its position among the world's significant oil exporters despite its small population and limited domestic infrastructure just seven years ago.

For now, the July figures offer a modest but notable data point. After four months in which the world watched Guyana's early production milestones give way to decline, the country has, at least for one month, turned the numbers back in its favour.
