据今日石油网2022年4月12日报道，在过去50年时期内钻遇了45口干井以后，圭亚那的石油历史在过去短短7年里发生了巨大的变化。自2015年以来，圭亚那海上迄今获得了31个发现，其中大多数发现是埃克森美孚公司的商业发现。
根据自然资源基金季度报告发布的最新数据，“自2015年以来，圭亚那海上已获得31个新发现。 其中27个新发现在斯塔布鲁克区块内，2个新发现在奥林杜伊克区块内，1个新发现在卡努库区块内，1个新发现在Corentyne区块内。”
在这些发现中，今年第一季度在Corentyne区块内获得了一个新发现，在斯塔布鲁克区块内获得了两个新发现。 Corentyne区块在Kawa-1井的发现是该区块的第一个发现，有可能开辟一个新的远景区。
在斯塔布鲁克区块，丽莎一期开发项目在2019年底开始生产，并在2020年12月达到了12万桶/天的峰值产能。丽莎二期开发项目的生产始于2022年2月，预计将在今年晚些时候达到22万桶/天的产能。
圭亚那当局还批准了帕拉亚油田的第三个开发项目和耶洛泰尔油田的第四个开发项目。这两个开发项目与丽莎一期和二期开发项目合并后，石油日总产量将超过80万桶。
据预测，到2027年前，圭亚那将有6到7个开发项目投入运营，到2030年结束前，圭亚那的石油日产量将增加到100万桶以上。
据估计，斯塔布鲁克区块的油气资源量约为100亿桶油当量，由埃克森美孚子公司旗下的埃索勘探和生产圭亚那有限公司运营。 埃克森美孚公司持有该区块45%的权益，美国赫斯圭亚那勘探有限公司持有30%的权益。

Record 31 discoveries made offshore Guyana since 2015
After encountering 45 dry holes over a period of 50 years, Guyana’s oil story has dramatically changed in just 7 years with the South American country hitting 31 discoveries offshore since 2015, most of which have been commercial finds made by ExxonMobil.
According to recent data published in the Natural Resource Fund Quarterly report, “Since 2015, 31 discoveries have been made offshore Guyana. Twenty–seven of those discoveries were made at the Stabroek block, two at the Orinduik block, one at the Kanuku block and one at the Corentyne block.”
Of these discoveries, one was made in the Corentyne Block and two new discoveries were made at the Stabroek Block during the first quarter of this year. The Corentyne Block discovery at the Kawa-1 well is the first for the block and potentially opens up a new play.
In the Stabroek block, the Liza Phase 1 Development began production in late 2019 and reached its peak capacity of 120,000 barrels per day (bpd) in December 2020. Production from Liza Phase 2 began in February 2022 and is expected to reach its capacity of 220,000 bpd later this year.
Authorities in Guyana have also approved a third project at Payara and a fourth at Yellowtail that when combined with Liza 1 and 2 will push daily production above 800,000 barrels of oil per day.
It is projected that by 2027, 6 to 7 projects will be in operation and that by the end of the decade, Guyana’s oil production will increase to more than 1 million bpd.
The Stabroek Block is estimated to contain resources of approximately 10 billion oil-equivalent barrels and is operated by ExxonMobil affiliate Esso Exploration and Production Guyana Limited. The company holds a 45% interest in the block, Hess Guyana Exploration Ltd. holds 30% interest.
