CGG 宣布在科特迪瓦近海塔诺盆地启动一项重大的新多客户端 3D 叠前深度偏移再成像项目。最近发现的 Baleine 油田附近的6,400 km 2重新成像地震数据集旨在深入了解这一高潜力油气藏。该项目得到了行业资金的支持，预计将于 2024 年底完成，并于 2024 年第一季度快速交付。
“最近发现的Baleine油田提高了人们对科特迪瓦近海勘探的兴趣，”CGG负责地球数据的执行副总裁林德春说。“我们的重新成像项目是同类项目中的第一个，利用尖端技术对前景和区域层面进行自信的评估，从而更好地了解这个世界级盆地的地下情况。由此产生的超现代数据集将为近场勘探机会提供独特的途径，使国际石油公司在快速跟踪这些高影响力前景的开发方面领先一步。”
CGG表示，计划利用其最新的专有技术对3D地震数据进行重新成像，包括时滞全波形反演（FWI）和定向FWI成像的潜在应用。该团队还计划对该项目区进行区域解释，以更好地了解塔诺盆地高前景碎屑岩和碳酸盐岩远景区的分布。
CGG has announced the start of a major new multi-client 3D prestack depth migration reimaging program in the Tano Basin offshore Côte d’Ivoire. The 6,400-km2 reimaged seismic data set near the recently discovered Baleine field aims to provide insight into this high-potential play. The project is supported by industry funding and is expected to be complete by the end of 2024, with a fast-track volume available in the first quarter of 2024.
“The recent discovery of the Baleine field has led to heightened exploration interest in offshore Côte d’Ivoire,” said Dechun Lin, CGG’s executive vice president for Earth data. “Our reimaging project is the first of its kind to utilize cutting-edge technology to enable confident evaluation at a prospect as well as regional level, to give a better picture of the subsurface in this world-class basin. The resulting ultramodern data set will offer unique access to near-field exploration opportunities, placing IOCs a step ahead in fast-tracking the development of these high-impact prospects.”
CGG said it plans to reimage the 3D seismic data with its latest proprietary technologies, including time-lag full waveform inversion (FWI) and the potential application of targeted FWI imaging. The team also plans to conduct a regional interpretation of the project area to provide a better understanding of the distribution of the highly prospective clastic and carbonate plays in the Tano basin.
