ExxonMobil has begun production at the Yellowtail project in Guyana, significantly increasing the country's total oil capacity to over 900,000 barrels per day. The project's floating production, storage, and offloading (FPSO) vessel, ONE GUYANA, joins three other FPSOs in the Stabroek block, bringing total installed capacity to above 900,000 barrels of oil per day [1][2][3].

The ONE GUYANA FPSO, the largest on the Stabroek block to date, has an initial annual average production of 250,000 barrels of oil per day (bopd) and a storage capacity of two million barrels. Oil produced from the FPSO will be marketed under the Golden Arrowhead crude brand [1][2][3].

ExxonMobil Guyana expects to achieve a total production capacity of 1.7 million oil equivalent barrels per day by 2030, with plans to develop eight projects in the Stabroek block. The company has successfully started up four complex offshore mega-projects under budget and ahead of schedule in the past five years, while simultaneously advancing plans for four additional projects by the end of the decade [1][2][3].

ExxonMobil Guyana Limited operates the Stabroek block and holds a 45% interest, with Hess Guyana Exploration Ltd. holding 30% and CNOOC Petroleum Guyana Limited holding 25% [1][2][3].
