Errea Wittu FPSO to Push Guyana Past 1 Million Bpd
Energy: Guyana
Key Facts
—Milestone. Once the Errea Wittu FPSO starts up, Guyana’s oil output is set to cross 1 million barrels per day for the first time.
—Vessel. Errea Wittu, meaning “abundance,” is ExxonMobil’s fifth FPSO for Guyana and the centrepiece of the US$12.7 billion Uaru project.
—Capacity. The vessel is designed to add about 250,000 barrels per day to current output of roughly 920,000 bpd.
—Timing. Errea Wittu set sail in early August 2026 and is scheduled to begin production in the fourth quarter.
—Ranking. Passing 1 million bpd would let Guyana overtake Venezuela as South America’s second-largest oil producer, behind Brazil.
Guyana is weeks away from a landmark: the arrival of the Errea Wittu FPSO, ExxonMobil’s fifth production vessel, is set to lift the country’s oil output past 1 million barrels per day for the first time.
The Milestone: Crossing 1 Million Barrels a Day
Guyana currently pumps roughly 920,000 barrels of oil per day from four floating vessels in the Stabroek block. The imminent start-up of a fifth, the Errea Wittu, is set to push that figure past 1 million barrels per day for the first time in the country’s history.
The threshold is more than symbolic. Analysts have flagged for months that Guyana could surpass 1 million bpd by year-end, a level that reorders South America’s energy hierarchy.
At that output, Guyana would overtake Venezuela to become the continent’s second-largest producer, trailing only Brazil, an extraordinary position for a nation that pumped its first barrel only in late 2019.
What the Errea Wittu FPSO Is
Errea Wittu, a name meaning “abundance” in an indigenous Guyanese language, is a floating production, storage and offloading vessel, or FPSO. These giant ships process crude at sea, store it, and offload it to tankers, removing the need for fixed platforms or long pipelines.
It is the fifth FPSO ExxonMobil has deployed offshore Guyana and the heart of the Uaru project, a development the company values at about US$12.7 billion. The vessel set sail for Guyana in early August 2026.
Once on station roughly 200 kilometres offshore, in about 1,690 metres of water, it will store around two million barrels of crude and process approximately 250,000 barrels per day.
How Guyana Got Here
Production began at the Liza field in December 2019 with a single FPSO. Vessels named Destiny, Unity, Prosperity and One Guyana followed, each adding capacity and lifting the country toward the 900,000-plus barrels a day it produces today.
The Errea Wittu makes five. Its Uaru project alone is designed to add about 250,000 barrels per day, the increment that carries national output over the 1 million mark.
For a country of roughly 800,000 people, the scale is staggering. Oil revenue now dwarfs the rest of the economy and flows into a sovereign wealth fund meant to spread the windfall across generations.
Why the Threshold Matters
Crossing 1 million barrels a day cements Guyana’s status as a systemically important supplier at a time when producers outside the OPEC alliance are prized for adding barrels. Every new vessel narrows the gap between Guyana and far larger, older oil states.
The Rio Times has tracked the Errea Wittu’s journey as it sailed toward its 250,000-bpd target; the fresh development is that its start-up now marks the moment Guyana breaks the 1 million-barrel ceiling.
Reaching the milestone before year-end would also front-load government revenue, feeding the national budget and the wealth fund faster than earlier forecasts had assumed.
What It Means for Expats and the Region
For expats and businesses in Guyana, the milestone signals that the boom still has room to run. More output means more contracts, more infrastructure spending and continued pressure on housing and services in and around Georgetown.
It also raises the stakes on governance. How transparently the additional revenue is managed, and how quickly it translates into roads, schools and jobs, will shape whether ordinary Guyanese feel the benefit of the numbers.
Regionally, a Guyana producing more than 1 million barrels a day changes the balance of energy power in South America, giving a tiny nation outsized weight in a market long dominated by Brazil, Venezuela and Colombia.
Frequently Asked Questions
When will Guyana pass 1 million barrels per day?
Output is expected to cross 1 million barrels per day once the Errea Wittu FPSO begins production, scheduled for the fourth quarter of 2026, on top of the roughly 920,000 bpd Guyana already produces.
What is the Errea Wittu FPSO?
It is ExxonMobil’s fifth floating production, storage and offloading vessel for Guyana and the centrepiece of the roughly US$12.7 billion Uaru project, designed to add about 250,000 barrels per day.
Will Guyana overtake Venezuela in oil production?
Passing 1 million barrels per day would make Guyana South America’s second-largest oil producer, ahead of Venezuela and behind only Brazil.
