Summary The escalating demand for deep underground energy sources, driven by the depletion of shallow resources, has raised concerns about the occurrence of dynamic disasters, which pose significant societal risks. In the context of engineering excavation processes, the presence of pre-existing and excavation-induced fractures significantly influences the evolution of complex geological disasters associated with mining activities. Traditional approaches to disaster prediction rely heavily on physical models and numerical simulations. However, these methods often suffer from limitations such as time-consuming and uneconomical drilling tests, as well as restricted coverage. To overcome these challenges, this study introduces a novel methodology that enables comprehensive imaging of the geological response, deformation patterns, and dynamic disaster prediction within the entire minefield of underground engineering works with a special emphasis on steeply inclined and extremely thick coal seams (SIETCS).

SUMMARY In this study, we address the persistent challenges of structural and time-lapse imaging within the Seismically Obscured Areas (SOAs) at Eldfisk field, North Sea. Despite numerous seismic programs, imaging efforts within SOAs at structures A and B continue to be hindered, primarily due to the presence of expansive, complex gas clouds in the overburden. To address this, we apply Full-Waveform Inversion (FWI) to 3D and 4D Ocean Bottom Node (OBN) data, aiming to enhance both structural and time-lapse imaging in these areas. Starting with a legacy velocity model, FWI is used as the main tool for model building, capturing detailed velocity changes associated with gas clouds. The refined model is then input into a Q (the quality factor)-compensated Reverse-Time Migration (Q-RTM) pseudo-gather-based imaging flow to generate significantly improved structural images in the SOAs. Additionally, our application of 4D FWI successfully uncovers time-lapse velocity changes that align with the injection and production history within the SOAs, which were not observed by traditional seismic-based 4D methods that require a good image.
摘要 在本研究中，我们探讨了在北海埃尔德菲斯克油田地震遮挡区（SOAs）内进行构造和延时成像所面临的长期挑战。尽管开展了大量地震项目，但结构 A 和结构 B 的地震遮挡区内的成像工作仍然受阻，主要原因是覆盖层中存在膨胀、复杂的气云。为解决这一问题，我们将全波形反演（FWI）应用于三维和四维海底节点（OBN）数据，旨在增强这些区域的构造和延时成像。从传统的速度模型开始，FWI 被用作建立模型的主要工具，捕捉与气体云相关的详细速度变化。然后将改进后的模型输入到基于 Q（质量因子）补偿的反向时间迁移（Q-RTM）伪采集成像流中，以生成明显改善的 SOA 结构图像。此外，我们应用 4D FWI 成功地发现了与 SOAs 内注入和生产历史相一致的延时速度变化，而传统的基于地震的 4D 方法需要良好的图像才能观测到这些变化。
