Rystad Energy said identical debottlenecking across three offshore developments in Guyana could unlock between 80,000 and 90,000 barrels per day (b/d) of additional production, targeting assets operated by ExxonMobil in the Stabroek Block.
The consultancy identified the Uaru, Whiptail and Hammerhead developments as candidates for the upgrades, which are aimed at improving output from existing production systems.

“Rystad Energy believes identical debottlenecking could unlock an additional 80,000 to 90,000 b/d across the Errea Wittu, Jaguar and Hammerhead [production units], all located in the Stabroek Block,” the firm said in an April 21 note.
The Errea Wittu floating production, storage and offloading (FPSO) vessel, tied to the Uaru development, is designed to produce oil at 250,000 barrels per day (b/d). S&P Global also believes Uaru, set for start-up this year, will be producing nearly 136,000 b/d, with a ramp-up to roughly 215,000 b/d by 2027.
For the Whiptail development, the Jaguar FPSO is designed with a production capacity of up to 250,000 b/d.
Hammerhead, ExxonMobil’s seventh sanctioned offshore project in the Stabroek Block, will be developed using an FPSO named Essequibo 1899. First oil is targeted for 2029. The vessel is designed to produce oil at up to 150,000 b/d and 90 million cubic feet of gas per day.Exxon has already demonstrated its ability to optimize Guyana projects, with about 130,000 b/d in new capacity added across three projects in the Liza and Payara fields. It also plans to boost production capacity at the Yellowtail project by about 26,000 b/d.
