苏里南国家石油公司在苏里南 52 区块的 Fusaea-1 勘探井在 52 区块发现了第三个碳氢化合物，该勘探井位于离岸约 170 公里处，距 Roystonea-1 以东 9 公里。 Wood Mackenzie 报告称，Roystonea 和 Fusaea 的可采资源量接近 4 亿桶。 “这足以支持石油加工能力高达 10 万桶/天的 FPSO 开发，”Wood Mackenzie 美洲（非 L48）上游主管 Mark Oberstoetter 表示。

该井于2024年2月开钻，在没有任何LTI的情况下钻探总深度5,227 m，遇到多个含油气坎帕尼亚砂岩储层包。正在进行进一步评估，以确定这一发现的全部范围及其与最近的 Roystonea-1 和 Sloanea-1 发现进行综合开发的潜力。

“继 Sloanea-1 和 Roystonea-1 发现之后，Fusaea-1 勘探井取得的良好成果巩固了 Petronas 在苏里南物质碳氢化合物资源方面的地位，”Petronas 上游执行副总裁兼首席执行官拿督表示阿迪夫·祖基菲利。

马来西亚国家石油公司勘探副总裁 Mohd Redhani Abdul Rahman 补充道：“Fusaea-1 的成功证明了我们对该地区地质认识的进步，这得益于最近 Roystonea-1 和 Sloanea-1 的突破。”这些发现显着扩大了 52 区块内的前景和综合石油和天然气开发潜力。为了追求可持续和高价值的物质资源，马来西亚国家石油公司仍然致力于在选定的重点区域进行勘探活动，作为其投资组合合理化努力的一部分。”

52区块面积4749平方公里，位于苏里南首都帕拉马里博海岸以北，位于未来的苏里南-圭亚那盆地内。 PETRONAS Suriname 是 52 区块的运营商，与埃克森美孚共同持有 50% 的参与权益。

除 52 号区块外，苏里南国家石油公司还经营 48 号区块和 63 号区块，并拥有 100% 的参与权益和 64 号区块 30% 的非经营权益。

自 2019 年以来，苏里南海域已发现 9 个深水油田，但该国仍在等待第一个开发批准。 据Wood Mackenzie称，TotalEnergies和APA公司即将批准在58号区块开发FPSO集群。Fusaea是继Sloanea和Roystonea之后在58号区块的第三个发现。 

“此外，APA Corp、Petronas 和 CEPSA 在 53 号区块钻探了 2022 年 Baja 发现项目。该区域位于 Roystonea 以北 8 公里处，最终可能成为更广泛的集群开发的一部分，”Oberstoetter 先生说。    

如果马来西亚国家石油公司在该区块开发天然气，它已经获得了税收减免。目前正在对 2020 年 Sloanea 发现的第二口井进行评估。 

“那里拥有 2 吨立方英尺的资源，可以在 2030 年代初支持浮式液化天然气的开发。此外，Fusaea 井的伴生气比预期更多，可以增加资源以支持未来的天然气开发。”Wood Mackenzie 拉丁美洲上游首席上游研究分析师 Luiz Hayum 表示。

Wood Mackenzie 目前拥有苏里南已发现的石油和液体资源量超过 24 亿桶，以及天然气资源量超过 12.5 吨立方英尺。

Petronas Suriname made a third hydrocarbon discovery in Block 52 at the Fusaea-1 exploration well in Suriname’s Block 52, located about 170 km offshore and 9 km east from Roystonea-1. Wood Mackenzie has reported that Roystonea and Fusaea’s recoverable resources are approaching 400 million barrels. “This could be enough to support an FPSO with an oil-processing capacity of up to 100,000 bbl/day FPSO development,” said Mark Oberstoetter, Head of Americas (non-L48) Upstream for Wood Mackenzie.

The well was spudded in February 2024 and drilled to a total depth of 5,227 m without any LTIs, encountering several oil and gas-bearing Campanian sandstone reservoir packages. Further evaluation is being undertaken to determine the full extent of this discovery and its potential for an integrated development with the recent Roystonea-1 and Sloanea-1 discoveries.

“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,” said Petronas Executive Vice President and CEO of Upstream, Datuk Adif Zulkifli.

Petronas Vice President of Exploration, Mohd Redhani Abdul Rahman added: “The success of Fusaea-1 is a testament to the advancements in our geological comprehension of this region, bolstered by recent breakthrough in Roystonea-1 and Sloanea-1. These discoveries have significantly expanded the prospectivity and integrated oil and gas development potential within Block 52. In pursuit of sustainable and high-value material resource, PETRONAS remains committed in its exploration activities in selected focus regions as part of its portfolio rationalization efforts.”

Block 52, which covers an area of 4,749 sq km, is located north of the coast of Paramaribo, Suriname’s capital city, within the prospective Suriname-Guyana basin. PETRONAS Suriname is the operator of Block 52 with a 50% participating interest together with ExxonMobil.

In addition to Block 52, Petronas Suriname operates Block 48 and Block 63 with 100% participating interest and 30% non-operating interest in Block 64.

Nine deepwater fields have been discovered in Suriname waters since 2019, but the country still awaits its first sanctioned development. According to Wood Mackenzie, TotalEnergies and APA Corp are close to sanctioning a cluster FPSO development on Block 58. Fusaea is the third discovery in Block 58, following Sloanea and Roystonea. 

“In addition, APA Corp, Petronas and CEPSA drilled the 2022 Baja discovery in Block 53. This is 8 km north of Roystonea and could eventually be part of a wider cluster development,” Mr Oberstoetter said.    

Petronas has already secured tax relief if it develops gas on the block. The 2020 Sloanea discovery is now being appraised with a second well. 

“Gas resources there of 2 tcf could anchor a floating LNG development in the early 2030s. Also, the Fusaea well had more associated gas than expected and could add resources to support future gas development,” said Luiz Hayum, Principal Upstream Research Analyst Latin America Upstream at Wood Mackenzie.

Wood Mackenzie now holds Suriname’s discovered resources at more than 2.4 billion bbl of oil and liquids and more than 12.5 tcf of gas.
