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 ft (70 m) of hydrocarbon-bearing sandstone and was drilled in 3840 ft (1170 m) of water. Drilling at Patwa-1 encountered 108 ft (33 m) of hydrocarbon-bearing sandstone and was conducted in 6315 ft (1925 m) of water. The Lukanani-1 well encountered 115 ft (35 m) of hydrocarbon-bearing sandstone and was drilled in a water depth of 4068 ft (1240 m). Operations are ongoing at Barreleye-1 and Lukanani-1.

Liam Mallon, president of ExxonMobil Upstream Company said: “These discoveries and the updated resource estimate increase the confidence we have in our ambitious exploration strategy for the Stabroek Block and will help to inform our future development plans for the southeast part of the block. ExxonMobil remains committed to delivering value at an accelerated pace to the people of Guyana, our partners and shareholders and reliably supplying affordable energy to meet increasing demand around the world.”

ExxonMobil currently has four sanctioned projects offshore Guyana. Liza Phase 1 is producing approximately 130 000 bpd 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 bpd using the Liza Unity FPSO. The third project, Payara, is expected to produce 220 000 bpd; 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 bpd when the ONE GUYANA FPSO comes online in 2025.

Guyana’s Stabroek Block is 6.6 million acres (26 800 km2). ExxonMobil affiliate Esso Exploration and Production Guyana Limited is the operator and holds 45% interest in the Block. Hess Guyana Exploration Ltd. holds 30% interest, and CNOOC Petroleum Guyana Limited holds 25% interest.
