Petronas 本周宣布在苏里南 52 号区块取得第三次成功发现。据马来西亚国家石油公司称，Fusaea-1 勘探井位于离岸约 170 公里处，遇到了几个含油气砂岩层段。

该井钻探总深度为 5227 米，位于先前发现的 Roystonea-1 井以东约 9 公里处。 Petronas 表示，正在评估最新油井的结果，以确定与分别于 2020 年和 2023 年发现的 Sloanea-1 井和 Roystonea-1 井进行搭配的可能性。

马来西亚国家石油公司上游执行副总裁兼首席执行官 Datuk Adif Zulkifli 在一份声明中表示：“继 Sloanea-1 勘探井之后，Fusaea-1 勘探井取得的良好成果巩固了马来西亚国家石油公司在苏里南重要碳氢化合物资源领域的地位。和 Roystonea-1 的发现。”

Petronas 与Noble Corp. 旗下的Noble Voyager 签订合同，负责钻探 Fusaea 油井，该油井已于 2 月份开钻。据Noble Corp称，今年4月，Petronas行使了延长第七代钻井船合同的选择权，以每天47万美元的价格在第52区块额外钻探至少一口井。该后续活动预计将持续70天。

52区块横跨近4750公里²，由拥有50%权益的马来西亚国家石油公司子公司运营。其余50%的股份由埃克森美孚持有，埃克森美孚上个月批准为邻国圭亚那建造第六艘FPSO 。

Petronas 还经营苏里南的 48 号区块和 63 号区块，拥有 100% 的权益，并拥有 64 号区块 30% 的非经营权益。

Wood Mackenzie 分析师报告称，Roystonea 和 Fusaea 发现的可采资源量可能接近 4 亿桶。该市场研究公司表示，这样的容量可以支持浮式生产、储存和卸载 (FPSO) 装置的部署，其铭牌处理能力高达 100,000 B/D，

此外，Wood Mackenzie 指出，美国独立 APA Corp.（Apache Corp. 的母公司）及其非运营合作伙伴 Petronas 和西班牙 CEPSA 于 2022 年钻探了 Baja 发现井。在 53 区块，该井位于 53 号区块以北仅 8 公里处。 Roystonea 很好，这表明运营商可能会选择将其纳入集群开发。

Wood Mackenzie 进一步推测，到 2030 年代初期，邻近区块的天然气储量合计为 2 Tcf，加上 Fusaea 井的高水平伴生气，可能会导致该地区出现浮动液化天然气项目。

Wood Mackenzie 勘探研究总监朱莉·威尔逊 (Julie Wilson) 在评论国油的国际勘探工作时称，苏里南是该石油公司的“亮点”，并补充说，这个南美国家“发挥国油在液化天然气开发方面的现有能力，同时向世界各地提供石油”。抵消其液化天然气加权投资组合。”

马来西亚国家石油公司 (Petronas) 最近的成功使苏里南近海自 2019 年以来的发现总数达到九个。

虽然尚未有运营商批准项目，但 TotalEnergies 及其非运营合作伙伴 APA 准备在今年某个时候就58 号区块拟议的 90 亿美元开发项目做出最终投资决定，目标是到 2028 年首次产出石油，峰值产量为 20 万桶B/D。 TotalEnergies表示，6262公里²区块的开发计划将使用FPSO。

此外，赫斯公司上个月在监管文件中证实，将于年底前对其持有权益的苏里南两个区块进行勘探作业。

42号区块毗邻TotalEnergies的大型特许区，由壳牌公司运营，该公司与雪佛龙公司和赫斯公司各持有33.3%的权益。正北面是52号区块，由埃克森美孚运营，Equinor和Hess为合作伙伴，各持有33.3%的股份。

根据新的海上发现，Wood Mackenzie 将苏里南已发现资源量估计提高到超过 24 亿桶石油和液体，以及另外 12.5 Tcf 的天然气。

^{相比之下，据信圭亚那面积达 26,000 km 2}的巨大 Stabroek 区块内蕴藏着超过 110 亿桶油当量（估计 20-30% 为天然气），埃克森美孚自 2015 年以来已在该区块内发现了 30 多项发现。

Petronas announced its third successful discovery this week in Suriname’s Block 52. The Fusaea-1 exploration well, located about 170 km offshore, encountered several oil- and gas-bearing sandstone intervals, according to the Malaysian national oil company.

The well was drilled to a total depth of 5227 m about 9 km east of a previous find, the Roystonea-1 well. Petronas said it is evaluating results from its latest well to determine the potential for a tie-in approach with the Sloanea-1 and Roystonea-1 wells, discovered in 2020 and 2023, respectively.

Datuk Adif Zulkifli, Petronas’ executive vice president and CEO of upstream, said in a statement, "The favorable results attained from the Fusaea-1 exploration well have solidified Petronas’ standing in Suriname for material hydrocarbon resource, following the Sloanea-1 and Roystonea-1 discoveries."

Petronas contracted the Noble Voyager, owned by Noble Corp., to drill the Fusaea well, which was spudded in February. In April, Petronas exercised an option to extend the contract for the seventh-generation drillship to drill at least one additional well in Block 52 at a day rate of $470,000, according to Noble Corp. This follow-up campaign is expected to last 70 days.

Block 52 spans nearly 4750 km² and is operated by a subsidiary of Petronas with a 50% interest. The remaining 50% stake is held by ExxonMobil which approved the construction of a sixth FPSO for neighboring Guyana last month.

Petronas also operates Suriname’s Block 48 and Block 63 with a 100% interest and has a 30% nonoperating interest in Block 64.

Analysts at Wood Mackenzie reported that the recoverable resources from the Roystonea and Fusaea discoveries may approach 400 million bbl. The market research firm said such volumes could support the deployment of a floating production, storage, and offloading (FPSO) unit with a nameplate processing capacity of up to 100,000 B/D,

Additionally, Wood Mackenzie noted that US independent APA Corp. (parent company of Apache Corp.) and its nonoperating partners Petronas and Spain’s CEPSA drilled the Baja discovery well in 2022. In Block 53, this well is just 8 km north of the Roystonea well, suggesting that the operators may opt to include it in a cluster development.

Wood Mackenzie further speculates that the adjoining blocks' combined gas reserves of 2 Tcf along with high levels of associated gas from the Fusaea well could lead to a floating liquified natural gas project in the region by the early 2030s.

Commenting on Petronas' international exploration efforts Julie Wilson, the exploration research director for Wood Mackenzie, called Suriname "a bright spot" for the oil company and added that the South American nation "plays to Petronas' existing competencies in LNG development while providing oil to offset its LNG-weighted portfolio.”

Petronas’ recent success brings the total number of discoveries offshore Suriname to nine since 2019.

While no operator has yet sanctioned a project, TotalEnergies and its nonoperating partner APA are poised to make a final investment decision sometime this year on a proposed $9-billion development in Block 58 that would aim for first oil by 2028 with a peak output of 200,000 B/D. TotalEnergies said the development scheme for the 6262- km² block would use an FPSO.

Additionally, Hess Corp. confirmed in regulatory filings last month that exploration operations will take place by year’s end on two Suriname blocks in which it holds an interest.

Adjacent to TotalEnergies’ large concession area, Block 42 is operated by Shell and it along with Chevron and Hess each hold a 33.3% interest. Directly to the north is Block 52, operated by ExxonMobil, with Equinor and Hess as partners, each holding a 33.3% share.

Based on the new offshore discoveries, Wood Mackenzie has increased its estimate of Suriname’s discovered resources to over 2.4 billion bbl of oil and liquids with another 12.5 Tcf of natural gas.

This compares to the more than 11 billion BOE (20–30% estimated to be gas) believed to be within Guyana's massive 26,000 km² Stabroek block where ExxonMobil has made more than 30 discoveries since 2015.
