ExxonMobil sanctions third development in Stabroek block off Guyana

ExxonMobil has made its final investment decision to proceed with the Payara field offshore development in Guyana after receiving government approvals.

Payara is the third project in the Stabroek Block and is expected to produce up to 220,000 barrels of oil per day after startup in 2024, using the Prosperity floating production, storage and offloading (FPSO) vessel.

ExxonMobil said on Wednesday that the $9 billion development will target an estimated resource base of about 600 million oil-equivalent barrels. Ten drill centres are planned along with up to 41 wells, including 20 production and 21 injection wells. 

“ExxonMobil is committed to building on the capabilities from our Liza Phase 1 and 2 offshore oil developments as we sanction the Payara field and responsibly develop Guyana’s natural resources”, said Liam Mallon, president of ExxonMobil Upstream Oil & Gas Company.

“We continue to prioritize high-potential prospects in close proximity to discoveries and maximize value for our partners, which includes the people of Guyana”.

ExxonMobil’s first offshore Guyana project, Liza Phase 1, began producing in late 2019, well ahead of the industry average for development time.

Liza Phase 2, remains on track to begin producing oil by early 2022. It will produce up to 220,000 barrels of oil per day at peak rates using the Liza Unity FPSO, which is under construction in Singapore. 

ExxonMobil is evaluating additional development opportunities in the Stabroek Block, including Redtail, Yellowtail, Mako and Uaru resources, and plans to have five drillships operating offshore Guyana by the end of this year. 

The Stabroek Block is 6.6 million acres (26,800 square kilometres) with current discovered recoverable resources estimated at more than 8 billion oil-equivalent barrels.

The 18 discoveries on the block to date have established the potential for at least five FPSO vessels producing more than 750,000 barrels of oil per day by 2026. 

ExxonMobil affiliate Esso Exploration and Production Guyana Limited is the operator and holds 45 per cent interest in the Stabroek Block. Hess Guyana Exploration holds 30 per cent interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25 per cent interest.
