Guyana entered the oil industry later than most major producers, but its growth has been exceptionally fast. Commercial production began only in December 2019. By late 2025, offshore output had passed 900,000 barrels per day, giving a country with a population of about one million people one of the world’s highest production rates per resident.
This expansion is centered on the Stabroek Block, a large deepwater area off Guyana’s Atlantic coast. A sequence of discoveries and standardized floating production projects has allowed operators to move rapidly from exploration to commercial output.
Oil has transformed Guyana’s exports, government revenue and investment capacity. It has also created difficult questions about contract terms, local participation, environmental protection and the management of rapid economic growth. The next phase will be defined not by whether Guyana can produce oil, but by how effectively it converts temporary petroleum wealth into lasting national development.
The Stabroek Block Changed Guyana’s Economic Scale
ExxonMobil announced the Liza discovery in 2015 after drilling in the Stabroek Block. The result opened a major new petroleum province along the northern coast of South America and encouraged further exploration in waters shared by Guyana, Suriname and neighboring states.
The first phase of the Liza development began producing in December 2019 through the Liza Destiny floating production, storage and offloading vessel, or FPSO. Liza Phase Two followed with the Liza Unity, while the Payara development introduced the Prosperity FPSO. The Yellowtail project began production from the ONE GUYANA vessel in August 2025.
Together, these four developments raised production above 900,000 barrels per day by November 2025. By early 2026, monthly output was averaging more than 900,000 barrels per day, placing Guyana among the larger oil producers in Latin America despite its small population and limited history in the industry.
The Stabroek Block is estimated to contain approximately 11 billion oil-equivalent barrels of recoverable resources. More than 30 discoveries have been announced, although not every discovery will become a separate commercial project.
Guyana exports nearly all of its crude because it does not have a large domestic refining market. Its offshore projects produce relatively light crude grades that can be sold to refineries in the United States, Europe and other Atlantic markets.
The result is an oil sector oriented toward exports from the beginning. Unlike older producers that first developed fields to serve domestic demand, Guyana’s production system was designed for large international cargoes loaded directly from offshore vessels.
Floating Production Systems Allow Rapid Expansion
Guyana’s oil industry is built around FPSOs rather than fixed platforms connected to an onshore terminal. Each vessel receives oil from subsea wells, processes the fluids, stores the crude and transfers it to export tankers.
This model reduces the need for extensive coastal infrastructure and allows the consortium to develop separate groups of discoveries in phases. It also creates a repeatable project structure: drill production and injection wells, install subsea equipment, connect the wells to an FPSO and begin exporting crude.
ExxonMobil operates the Stabroek Block with a 45 percent interest. Chevron holds 30 percent following its acquisition of Hess, while CNOOC Petroleum Guyana owns the remaining 25 percent.
The partners have committed more than US$60 billion to seven government-approved developments. The fifth project, Uaru, is expected to add about 250,000 barrels per day when it begins operating. Whiptail, the sixth development, is scheduled to add another 250,000 barrels per day, while Hammerhead is expected to provide approximately 150,000 barrels per day from 2029.
Uaru and Whiptail have been progressing toward production in 2026 and 2027 respectively. Once both are operating, Guyana’s capacity could rise beyond 1.4 million barrels per day. ExxonMobil expects eight developments to support capacity of approximately 1.7 million barrels per day by 2030.
Development may continue beyond the currently sanctioned projects. ExxonMobil has outlined Longtail as a possible oil and gas development and has applied for environmental authorization for additional projects and exploration. In June 2026, the company sought permission for a 35-well exploration program planned for 2028 through 2033.
This continuing exploration means Guyana’s production plateau has not yet been firmly established. The size and duration of future output will depend on new discoveries, reservoir performance, regulatory approvals and the commercial value of smaller fields.
Oil Revenue Is Financing a New Development Model
Oil has changed the scale of Guyana’s public finances. Government revenue comes from royalties and the state’s share of profit oil, with payments deposited into the Natural Resource Fund.
The fund was created to hold petroleum income, support economic stability and finance national priorities through legally approved withdrawals. By the end of 2024, it had reached approximately US$3.1 billion. Continued production from new projects is expected to increase future inflows substantially.
Guyana’s broader economy has expanded at an exceptional rate. The International Monetary Fund reported average real economic growth of 47 percent per year from 2022 through 2024. Real oil-sector output increased by almost 58 percent in 2024, while the non-oil economy grew by more than 13 percent.
The government has used rising revenues to support roads, bridges, housing, energy projects, health facilities, education and other infrastructure. These investments can reduce costs across the economy and connect communities that previously lacked reliable transport or public services.
However, rapid spending creates its own risks. A small construction market can face shortages of workers, materials and management capacity. Large inflows can increase prices, raise wages faster than productivity and make other export industries less competitive.
Guyana must therefore balance immediate infrastructure needs with savings and careful project selection. The value of the oil boom will depend less on headline production figures than on whether investments improve productivity after petroleum output eventually declines.
Local Content Is Expanding Around a Foreign-Led Industry
Guyana did not have a mature offshore supply chain when production began. Most of the engineering, drilling, subsea equipment, vessels and specialist services initially came from international companies.
The Local Content Act introduced requirements intended to direct a larger share of petroleum spending toward Guyanese workers and businesses. The system covers designated services and requires contractors to submit plans and performance reports.
Local participation has expanded in transportation, accommodation, catering, fabrication, warehousing, environmental services, professional support and other fields. Guyanese workers have also moved into technical and offshore roles as training programs develop.
Even so, deepwater production remains a highly specialized and capital-intensive business. FPSO construction, subsea systems, reservoir engineering and complex drilling services depend on international suppliers with experience and global manufacturing networks.
The practical objective is not to reproduce the entire offshore supply chain within Guyana. It is to identify areas where domestic companies can become competitive, retain more value and develop skills that remain useful outside the oil sector.
Poorly designed local-content requirements could raise costs or encourage companies that exist mainly to satisfy ownership rules. Effective policy requires transparent registration, realistic targets, workforce development and opportunities that allow local firms to build genuine operating capacity.
Contract Terms and Regulation Remain Central to the Oil Debate
The 2016 Stabroek production-sharing agreement was signed before the full scale of the resource was understood. It provides the government with a 2 percent royalty and allows up to 75 percent of monthly petroleum revenue to be used for cost recovery. The remaining profit oil is divided between the state and the contractors.
The agreement helped attract investment when Guyana was an unproven frontier market, but its terms have become a continuing source of political and public debate. As production increased, critics argued that the government’s share was too low for a resource of Stabroek’s quality and scale.
Guyana has developed stronger terms for newer petroleum agreements, including higher royalties and revised fiscal conditions. However, the original Stabroek agreement continues to govern the projects responsible for almost all current output.
Cost auditing is especially important. The amount classified as recoverable expenditure directly affects how much profit oil is available for division. Guyana has expanded its regulatory and technical capacity, but overseeing projects worth tens of billions of dollars remains demanding for a relatively small public administration.
Environmental oversight is another major issue. Offshore production occurs far from the coast, but a large spill could affect fisheries, coastal ecosystems and neighboring states. In 2025, Guyana adopted legislation establishing strict liability for oil-pollution damage and requiring financial assurances from responsible companies.
The territorial dispute with Venezuela adds a geopolitical dimension. Venezuela claims the Essequibo region administered by Guyana and has disputed parts of the associated offshore area. The case remains before the International Court of Justice, while Guyana continues to authorize operations in waters it considers part of its territory.
Guyana’s Oil Future Depends on What Remains After the Boom
Guyana is moving from the opening phase of oil production into a period of industrial scale. New FPSOs, wells and export cargoes will continue increasing output, while petroleum revenue will give the government financial resources that were previously unavailable.
The central test is whether those resources create a more productive and diversified economy. Roads, electricity, education and public services can support long-term growth, but only when projects are selected carefully and institutions can manage them.
Oil will dominate Guyana’s economy for years, yet the resource is finite and exposed to global price changes. Successful development will require savings, transparent revenue management, credible regulation and investment outside petroleum.
Guyana’s offshore fields have already changed the country’s position in world energy markets. The lasting result will depend on whether the oil industry becomes the foundation for broader national development rather than the economy’s permanent limit.
