ExxonMobil’s eighth Guyana development, Longtail, should get its final investment decision (FID) in 2026, country President Alistair Routledge said Wednesday.
He told attendees at the Guyana Energy Conference the project is a challenging excursion based on the technical challenges the operator will face to tap the non-associated gas resources. Longtail will be the first project to tap non-associated gas, meaning the gas is not a by-product of oil production.
Longtail will target production of 1.2 billion cubic feet of gas per day (cf/d), a massive amount compared to the much smaller scale plans to tap associated gas from the Liza and Hammerhead fields. Those associated gas projects will target collective production of about 125 million cf/d.
In addition to Longtail’s gas output, it will target oil production up to 250,000 barrels per day (b/d).
