ExxonMobil has made three discoveries offshore Guyana and increased its estimate of the recoverable resource for the Stabroek Block to nearly 11 billion oil-equivalent barrels.The three discoveries are southeast of the Liza and Payara developments and bring to five the discoveries made by ExxonMobil in Guyana in 2022. The Barreleye-1 well encountered approximately 230 feet (70 meters) of hydrocarbon-bearing sandstone and was drilled in 3,840 feet (1,170 meters) of water. Drilling at Patwa-1 encountered 108 feet (33 meters) of hydrocarbon-bearing sandstone and was conducted in 6,315 feet (1,925 meters) of water. The Lukanani-1 well encountered 115 feet (35 meters) of hydrocarbon-bearing sandstone and was drilled at a water depth of 4,068 feet (1,240 meters). Operations are ongoing at Barreleye-1 and Lukanani-1.
ExxonMobil currently has four sanctioned projects offshore Guyana. Liza Phase 1 is producing approximately 130,000 barrels per day using the Liza Destiny floating production storage and offloading (FPSO) vessel. Liza Phase 2, which started production in February, is steadily ramping up to its capacity of 220,000 barrels per day using the Liza Unity FPSO. The third project, Payara, is expected to produce 220,000 barrels per day; construction on its production vessel, the Prosperity FPSO, is running approximately five months ahead of schedule with start-up likely before year-end 2023. The fourth project, Yellowtail, is expected to produce 250,000 barrels per day when the ONE GUYANA FPSO comes online in 2025.
