TGS 是一家全球领先的能源数据和情报提供商，该公司宣布增强其塞拉利昂近海 Fusion 3D 地震数据集，重点关注 Vega 勘探区。该再处理项目利用先进的地震成像工作流程来增强深度数据，为勘探该地区的石油和天然气公司提供更清晰的地下洞察。南美洲最近的发现加剧了人们对该地区的兴趣，将塞拉利昂定位为一个有希望的勘探前沿。

随着国际石油公司 (IOC) 和独立公司的兴趣日益浓厚，Fusion 3D 数据的发布正逢其时。Vega

勘探区已被确定为塞拉利昂近海水域的一个有希望的目标，现代深度数据将有助于进一步绘制未钻探的勘探区，推动钻探活动的进展。

塞拉利昂拥有成为非洲领先勘探前沿的所有地质要素。 “凭借可利用的土地面积、诱人的财政条件以及深度偏移的高质量 Fusion 3D 数据，勘探潜力巨大，”TGS 多客户执行副总裁 David Hajovsky 表示。“GS 致力于支持塞拉利昂能源部门的发展，这一举措将促进投资并巩固塞拉利昂作为全球能源市场新兴参与者的地位，并与 PDSL（塞拉利昂石油局）和其他利益相关者密切合作，最大限度地为所有相关方带来这一举措的利益。”

迄今为止，塞拉利昂大陆斜坡地区已钻探了 8 口井，目标是在多个地层层面上展示储层质量的海底扇系统。该地区在塞拉利昂盆地北部的几个盆地底部扇体中蕴藏着未开发的机遇，其中的扭转事件创造了一个同裂谷高原，具有吸引人的钻探深度。

基于 TGS 为塞拉利昂提供的多客户组合的成功，该再处理项目包括约 7,500 平方公里的 3D 地震数据，辅以 16,000 线公里的 2D 叠前深度偏移 (PSDM) 数据，并得到重力、磁力和解释数据产品的支持。

该项目由行业资金支持，预计将于 2025 年第三季度提供最终结果。

TGS, a leading global provider of energy data and intelligence, announced the enhancement of its Fusion 3D seismic dataset offshore Sierra Leone, focusing on the Vega prospect. This reprocessing project leverages advanced seismic imaging workflows to enhance depth data, offering clearer subsurface insights for oil and gas companies exploring the area. Recent discoveries in South America have intensified interest in the region, positioning Sierra Leone as a promising exploration frontier.

With growing interest from international oil companies (IOCs) and independents, the Fusion 3D data comes at a crucial time.

The Vega prospect has been identified as a promising target within Sierra Leone's offshore waters, and modern depth data will be instrumental in further mapping the undrilled prospect, enabling progress toward drilling activities.

“Sierra Leone has all the geological ingredients to emerge as a leading exploration frontier in Africa. With accessible acreage, attractive fiscal terms, and this depth-migrated high-quality Fusion 3D data, the exploration potential is strong,” said David Hajovsky, Executive Vice President of Multi-Client at TGS. “TGS is committed to supporting Sierra Leone’s energy sector development, and this initiative will promote investment and reinforce Sierra Leone's standing as an emerging player in the global energy market, working closely with PDSL (Petroleum Directorate of Sierra Leone) and other stakeholders to maximize the benefits of this initiative for all parties involved.”

To date, eight wells have been drilled on the continental slope region of Sierra Leone, targeting submarine fan systems that demonstrate reservoir quality at multiple stratigraphic levels. The region holds unexplored opportunities in several basin-floor fans in the northern Sierra Leone Basin, where transpressional events created a syn-rift plateau with attractive drilling depth to target.

Building on the success of TGS’s multi-client portfolio for Sierra Leone, this reprocessing project includes approximately 7,500 square kilometres of 3D seismic data, complemented by 16,000 line kilometres of 2D Pre-Stack Depth Migrated (PSDM) data, and supported by gravity, magnetic, and interpretive data products.

This project, supported by industry funding, is expected to deliver final results in Q3 2025.
