全球领先的能源数据和情报提供商TGS已启动对利比里亚近海哈珀盆地Sunfish 3D（Vision）地震勘探数据的重新处理。该项目由行业资金支持，是TGS持续致力于提升前沿盆地勘探准备水平的一部分。Sunfish

3D勘探覆盖面积约6100平方公里，最初由TGS于2013年采集。该项目将利用现场采集的磁带数据，通过应用现代成像工作流程，提供完整的3D Kirchhoff叠前深度偏移数据，从而提升数据质量和对地下结构的理解。最终产品计划于2026年第三季度发布。

重新处理的数据集旨在提供更清晰的上白垩统油藏成像，重点在于保持整个数据中AVO响应的保真度。这将使勘探团队能够更有信心地应用先进的储层表征工作流程，从而支持在这一复杂环境下进行更可靠的勘探前景评估。

TGS多客户执行副总裁David Hajovsky评论道：“Sunfish 3D地震勘测数据的重新处理标志着哈珀盆地勘探准备工作成熟度提升的重要一步。该项目是我们长期致力于更新利比里亚地下数据基础，并支持在这个勘探程度较低的盆地做出基于数据的明智勘探决策的更广泛承诺的一部分。”

该项目是TGS与利比里亚国家石油公司（NOCAL）合作开展的多年期项目的一部分，旨在更新利比里亚近海地震数据组合。项目完成后，TGS将通过先进的现代叠前深度偏移工作流程，重新处理利比里亚近海所有可用的二维和三维地震数据，其中包括超过5万公里的二维地震数据和超过3.1万平方公里的三维地震数据。这项努力凸显了TGS对支持利比里亚及更广泛的西非边缘地区的勘探活动和数据驱动决策的长期承诺。

TGS, a leading global provider of energy data and intelligence, has commenced reprocessing of the Liberia Sunfish 3D (Vision) seismic survey in the Harper Basin, offshore Liberia. The project is supported by industry funding and forms part of TGS锟� continued commitment to advancing exploration readiness across frontier basins.

The Sunfish 3D survey covers approximately 6,100 square kilometers and was originally acquired by TGS in 2013. The project will deliver a full 3D Kirchhoff Pre-Stack Depth Migration from field tapes, applying modern imaging workflows to enhance data quality and subsurface understanding. Final products are scheduled for release in the third quarter of 2026.

The reprocessed dataset is designed to deliver clearer imaging of Upper Cretaceous plays, with a strong focus on preserving the fidelity of AVO response throughout the data. This enables exploration teams to apply advanced reservoir characterization workflows with greater confidence, supporting more robust prospect evaluation in this complex setting.

David Hajovsky, Executive Vice President of Multi-Client at TGS commented, 锟絉eprocessing the Sunfish 3D survey represents an important step in maturing exploration readiness in the Harper Basin. This project is part of our broader, long-term commitment to rejuvenating the subsurface data foundation across Liberia and supporting informed, data-driven exploration decisions in this underexplored basin.锟�

This project is part of a broader, multi-year campaign by TGS in collaboration with the National Oil Company of Liberia (NOCAL) to rejuvenate the offshore Liberia seismic data portfolio. Upon completion, TGS will have reprocessed all available 2D and 3D seismic data in offshore Liberia, comprising of more than 50,000 kilometers of 2D seismic and over 31,000 square kilometers of 3D seismic through advanced modern pre-stack depth migration workflows. This effort underscores TGS锟� long-term commitment to supporting exploration activity and data-driven decision-making in Liberia and the wider West African margin.
