据Oil & Gas Journal网站4月27日消息 埃克森美孚在圭亚那近海Stabroek区块的Uaru-2井发现了一处石油，使该区块的总可采资源量估计增加了90多亿桶油当量。
在Uaru-2钻井时，遇到了120英尺（36.7米）的高质量含油储层，包括在Uaru-1原始发现层段下方新发现的层段。这口井是在5659英尺（1725米）深的水中钻探，位于Uaru-1井以南约6.8英里（11公里）。
2020年1月，埃克森美孚Uaru-1是该区块的第16个发现。该井遇到94英尺（29米）高质量含油砂岩储层，在6342英尺（1933米）的水中钻井。
2021年3月，埃克森美孚获得了第六艘钻井船Noble Sam Croft，用于圭亚那近海的勘探和评估钻井活动。第四个项目Yellowtail已在区块内确定，预计2025年底启动，等待政府批准和项目批准。该项目将开发Yellowtail和Redtail油田，位于Liza开发区东南约19英里（30公里）。
埃克森美孚预计到2027年至少有6个项目上线，并预计将有多达10艘浮式生产储油船的潜力，以开发其目前的可回收资源平衡。
随着Liza Unity浮式生产储油船准备于今年晚些时候驶离新加坡，Liza二期工程的启动仍按2022年的目标进行。Unity浮式生产储油船的峰值产量为22万桶/天。帕亚拉油田的第三个项目Prosperity浮式生产储油船的船体已完工，新加坡已开始上部结构施工活动，启动目标为2024年。
埃克森美孚子公司埃索勘探与生产圭亚那有限公司是占地660万英亩的Stabroek区块的运营商，拥有45%的权益。赫斯圭亚那勘探有限公司持有30%的股份。

ExxonMobil makes oil discovery offshore Guyana
ExxonMobil made an oil discovery offshore Guyana at the Uaru-2 well in the Stabroek block, adding to block's gross recoverable resource estimate of more than 9 billion boe.
Drilling at Uaru-2 encountered 120 ft (36.7 m) of high-quality oil-bearing reservoirs including newly identified intervals below the original Uaru-1 discovery. The well was drilled in 5,659 ft (1,725 m) of water and lies some 6.8 miles (11 km) south of the Uaru-1 well.
In January 2020, ExxonMobil Uaru-1 marked the 16th discovery in the block. The well encountered 94 feet (29 m) of high-quality oil-bearing sandstone reservoir and was drilled in 6,342 ft (1,933 m) of water (OGJ Online, Jan. 27, 2020).
In March 2021, ExxonMobil secured a sixth drillship, the Noble Sam Croft, for exploration and evaluation drilling activities offshore Guyana. A fourth project, Yellowtail, has been identified within the block with anticipated start up in late 2025 pending government approvals and project sanctioning. This project will develop the Yellowtail and Redtail fields, which lie about 19 miles (30 km) southeast of the Liza developments (OGJ Online, Sept. 8, 2020).
ExxonMobil anticipates at least six projects online by 2027 and sees potential for up to 10 FPSOs to develop its current recoverable resource balance.
Start-up of Liza Phase 2 remains on target for 2022, as the Liza Unity FPSO prepares for sail away from Singapore later this year. The Unity FPSO has a production capacity of 220,000 b/d of oil at peak rates. The hull for the Prosperity FPSO, the third project at Payara field, is complete, and topsides construction activities have commenced in Singapore with a startup target of 2024.
ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. is operator of the 6.6-million-acre Stabroek block with 45% interest. Hess Guyana Exploration Ltd. holds 30.
