ExxonMobil Guyana Limited’s proposed Haimara project could require 24 to 60 wells, placing the gas-focused development in the middle of the Stabroek Block lineup by drilling scope.
The figure, shown in a comparison of ExxonMobil Guyana’s offshore projects revealed during the project’s scoping meeting on June 11, puts it above Hammerhead, Liza 1, and Liza 2 at the upper end of its range. But it remains below the largest well-count ranges listed for Whiptail, Uaru, and Yellowtail.
Haimara is proposed for the Stabroek Block, about 222 kilometers offshore Guyana. It would be the ninth hydrocarbon development in the block. ExxonMobil Guyana operates the Stabroek Block with a 45% stake. Hess, now owned by Chevron, holds 30%, while CNOOC holds 25%.
The project would be different from ExxonMobil Guyana’s earlier Stabroek Block developments because it is being advanced as a gas-focused project. Haimara would target retrograde gas, with condensate separated on the floating production, storage, and offloading vessel. The remaining gas would be reinjected into the reservoir for pressure maintenance and increased condensate recovery.

The well count shows Haimara would be larger in drilling scope than some of the earlier and proposed developments. Hammerhead is listed at 14 to 30 wells. Liza 1 has 17 wells, while Liza 2 is listed at up to 33 wells. Payara is listed at up to 45 wells.
Haimara’s upper range of 60 wells is below Whiptail, which is listed at 33 to 72 wells. It is also below Yellowtail’s range of 45 to 67 wells and Uaru’s range of 38 to 63 wells.
The comparison shows Haimara is not ExxonMobil Guyana’s largest project by oil/condensate output. Its initial condensate production target is listed at 160,000 to 220,000 barrels per day. That is below Longtail’s initial condensate target of 200,000 to 290,000 b/d.
It is also below the current oil production capacities observed for Payara and Liza 2, which are listed at about 265,000 b/d and 270,000 b/d, respectively. Liza 1 has produced up to 150,000 b/d.
Haimara’s condensate production target is higher than Hammerhead’s initial oil production range of 120,000 to 180,000 b/d. That places Haimara above Hammerhead by both well count and liquid hydrocarbon production.
The project’s scale is also reflected in its FPSO storage capacity. Haimara is listed with 2 million barrels of oil storage capacity, in line with the larger Stabroek Block projects shown in the comparison. Hammerhead is listed at 1.5-1.6 million barrels, while Liza 1 is listed at 1.6 million barrels.
Haimara’s export tanker offloading frequency is listed at every three to six days. That is more frequent than Hammerhead’s five to seven days and Liza 1’s five to 10 days. Several of the larger Stabroek Block projects are listed at around four days.
The project summary said the proposed Haimara FPSO would be “a newly built floating facility with double side and single bottom protection.”
The vessel would be about 1,096 feet, or 334 meters, long; 197 feet, or 60 meters, wide; and 108 feet, or 32.8 meters, deep. It would be moored at the Haimara location, with a system designed to keep the FPSO on station continuously for the 30-year duration of the project.
The FPSO would be positioned about 54 kilometers southeast of the current location of the ONE GUYANA FPSO and 36 kilometers from the planned location of the Longtail FPSO.
