ExxonMobil is set to enhance natural gas production from its oil-focused operations in Guyana via a large-scale project, in response to the government’s request to supply more gas to onshore power and petrochemical development projects.
The company’s offshore developments in Guyana have made the country the world’s “fastest-growing” oil producer, but the government has urged the company to utilise associated natural gas more effectively.

The Exxon-led consortium, including Hess and CNOOC, is planning to expand gas production, particularly through projects such as Longtail, which focuses on non-associated gas.
During an energy conference in Guyana capital Georgetown, Exxon’s Guyana head, Alistair Routledge, presented the Wales Gas Vision concept, which will transport gas from the company’s Longtail development to shore for various petrochemical and power projects, reported Bloomberg.
The Wales Gas Vision is separate from Guyana’s gas-to-energy project, for which Exxon has already built an underwater pipeline to supply power generation fuel.
However, Exxon’s plans will depend on market demand, pricing and timing.
A final investment decision for Longtail, which could yield up to 1.2 billion cubic feet per day of gas, is expected next year.
Longtail is expected to start production by 2029. The gas will be transported through a $1bn pipeline, which was completed last year.
The government will utilise a portion of the gas from Exxon’s Stabroek Block, conveyed through this pipeline, for power generation and the production of natural gas liquids, reported Reuters.
Exxon is also exploring LNG technology to connect Guyana’s gas to global markets.
Additionally, a gas processing and liquefied natural gas (LNG) offshore facility is planned by Fulcrum LNG.
According to Guyana’s Energy Minister, Vickram Bharrat, Exxon may construct additional pipelines to transport the government’s share of profit gas to Fulcrum LNG’s facility.
This plant will enable LNG exports and supply gas for fertilizer and alumina production in Guyana’s Berbice area.
While total investment figures for these projects remain undisclosed, Bharrat emphasised the necessity for a comprehensive assessment of gas resources at Exxon’s block.
The government, however, is confident in the commercial viability of the gas.
“There will be a shift towards gas utilisation and monetisation,” Bharrat said at the conference, revealing that the government’s ambitious gas strategy is set to launch this year.
To date, Hess, ExxonMobil Guyana and CNOOC have pledged nearly $55bn for six approved developments on the Stabroek Block.
The first three oil projects are currently producing more than 650,000 barrels of oil per day (bopd), with plans to increase capacity to more than 1.3 million barrels by the end of 2027.
In February 2025, Guyana allocated $51.2bn to enhance gas-to-energy projects, with $36.2bn earmarked for a natural gas power plant and a natural gas liquid plant.
