领先的能源数据和情报提供商TGS欣然宣布，在V环盆地完成PGS23M02NWS地震勘探，这是为期两年的勘探项目的一部分。该项目将通过最新的处理技术和采集技术增强地下数据，帮助业界更好地了解这一复杂的火山区域。

该勘探是经典双源PGS16004 Aasta Hansteen项目的延续，勘探范围约8000平方千米。采集配置采用宽拖三源以改善近偏移距覆盖范围，深拖多传感器GeoStreamer以提高信噪比，并采用延伸拖缆以更好地进行全波形反演（FWI）估算。TGS应用了包括机器学习技术在内的宽带处理技术来抑制噪声并改善深部侵入岩的成像。

多客户执行副总裁David Hajovsky对该项目评论道：“这些高质量的数据有助于深入了解V环外层的区域和局部构造及地层，有助于降低勘探风险并提高发现潜力。在这些地质复杂的环境中，使用现代技术进行大规模三维勘探和一致性处理至关重要。”

V环盆地位于挪威中部大陆边缘，过去二十年来钻探活动有限。包括Obelix（6605/1-2）、Irpa（6705/10-1）和Balderbröu（6604/5-1）在内的发现主要在古新世和上白垩统产出天然气。虽然Aasta Hansteen油田已经开发，但在下白垩统和侏罗纪层段的钻探尚未成功。

V环盆地是挪威中部大陆边缘一个勘探程度较低的地区，过去二十年来钻探活动有限。目前已发现的天然气位于古新世和上白垩统层段（例如Obelix，6605/1-2；Irpa，6705/10-1；Balderbrö，6604/5-1）以及已开发的Aasta Hansteen油田。试图钻探下白垩统和侏罗统的井均未成功。古新世至早始新世

期间的一次重大岩浆事件导致了大面积侵入，对储层结构、成熟度和流体流动产生了重大影响。过去十年来，地下成像技术的进步正在帮助地球科学家解读这些特征及其对区域油气系统的影响。过去十年

TGS, a leading provider of energy data and intelligence, is pleased to announce the completion of the PGS23M02NWS seismic survey in the Vøring Basin, part of a two-year campaign. This will help the industry better understand this complex volcanic region by enhancing the subsurface data with the latest processing techniques and acquisition technology.

The survey, a continuation of the vintage dual source PGS16004 Aasta Hansteen project, spans roughly 8,000 km². The acquisition configuration employed wide tow triple sources for improved near-offset coverage, deep-tow multi-sensor GeoStreamer to enhance signal-to-noise ratio, and extended streamers for better full waveform inversion (FWI) estimation. TGS applied broadband processing, including machine learning techniques, to suppress noise and improve imaging of deeper intrusives.

Executive Vice President of Multi-Client, David Hajovsky, commented on the project, “This high-quality data volume provides insight into regional and local structures and stratigraphy in the Outer Vøring, supporting efforts to reduce exploration risk and improve the potential for discovery. Large-scale 3D surveys using modern technology and consistent processing are essential in these geologically complex settings.”

The Vøring Basin, located on the mid-Norwegian continental margin, has seen limited drilling in the past two decades. Discoveries, including Obelix (6605/1-2), Irpa (6705/10-1), and Balderbrå (6604/5-1), have primarily yielded gas in the Paleocene and Upper Cretaceous. While the Aasta Hansteen field has been developed, drilling in the Lower Cretaceous and Jurassic intervals has yet to be successful.

The Vøring Basin represents an underexplored area on the mid-Norwegian continental margin with limited drilling over the last two decades. The discoveries made have been gas in the Paleocene and Upper Cretaceous intervals (e.g., Obelix, 6605/1-2; Irpa, 6705/10-1; Balderbrå, 6604/5-1) and the developed Aasta Hansteen field. Well drilling attempts to reach Lower Cretaceous and Jurassic have been unsuccessful.

A major magmatic event during the Paleocene–Early Eocene resulted in extensive intrusions, significantly impacting reservoir structure, maturation, and fluid flow. Improved subsurface imaging over the last decade is helping geoscientists interpret these features and their influence on the regional petroleum system.

Over the last decade, challenging subsurface imaging with intrusions and hydrothermal vent complexes has improved through acquisition and improved subsurface imaging along the Atlantic Margin. Understanding these, how they are linked, and their influences on the petroleum system and reservoir levels are crucial for the continued exploration of the region.
