ExxonMobil started production at Payara, Guyana’s third offshore oil development on Stabroek block, bringing total production capacity in Guyana to about 620,000 b/d, the company said Nov. 14.
The Prosperity floating, production, storage and offloading (FPSO) vessel—which arrived in Guyana waters in April—is expected to reach initial production of about 220,000 b/d over first-half 2024 as new wells come online (OGJ Online, Apr. 19, 2023).
The additional capacity will be the third major milestone towards reaching a combined production capacity of more than 1.2 MMboe/d on the block by year-end 2027, the operator said.
The Prosperity FPSO, with a design that largely replicates that of the Liza Unity FPSO, will have associated gas treatment capacity of 400 MMcfd and water injection capacity of 250,000 b/d. It is spread moored in water depth of about 1,900 m and will be able to store around 2 million bbl of crude oil.
ExxonMobil Guyana anticipates six FPSOs will be in operation on Stabroek block by year-end 2027. Yellowtail and Uaru, the fourth and fifth projects, are in progress and will each produce about 250,000 b/d of oil. The company is working with the government of Guyana to secure regulatory approvals for a sixth project at Whiptail.
ExxonMobil Guyana Ltd. operates the Stabroek block and holds 45% interest. Hess Guyana Exploration Ltd. holds 30% interest, and CNOOC Petroleum Guyana Ltd. holds 25% interest.
