Enabling deep-learning-based uncertainty quantification at scale for post-stack UHR seismicinversion
SUMMARY An accurate characterization of the shallow subsurface is crucial for evaluating the load-bearing capacity at offshore wind farm sites. It is widely recognized that seismic methods, particularly inversion, can significantly enhance traditional geotechnical approaches with three-dimensional information that is otherwise unavailable. A comprehensive geotechnical analysis, however, relies on several scenarios with different confidence levels […]
SUMMARY We present a novel framework for handling large, irregularly shaped and sampled, N-Dimensional seismic volumes that remains compatible with graph-flow-based seismic processing applications commonly used in our industry. Leveraging an abstract I/O framework, we demonstrate how to interconnect standard trace-wise and gather-wise processing steps with large volume-wise processing steps in a hardware-agnostic but scalable […]
SUMMARY Ultra-high resolution (UHR) seismic data has emerged as a powerful tool for enhancing quantitative ground model building, particularly in applications such as offshore wind farm planning. However, effective utilization of UHR data hinges on overcoming unique preprocessing challenges, particularly receiver de-ghosting, which is complicated by dynamic sea-surface fluctuations and receiver depth uncertainties. This paper […]
SUMMARY In recent years, deep learning (DL) has emerged as a promising alternative approach for various seismic processing tasks, including primary estimation (or multiple elimination), a crucial step for accurate subsurface imaging. In geophysics, DL methods are commonly based on supervised learning from large amounts of high-quality labelled data. Instead of relying on traditional supervised […]
SUMMARY In frontier areas, 3D seismic surveys are sometimes unavailable due to their high operational costs, necessitating the use of 2D seismic surveys. However, 2D seismic surveys are generally not ideal for accurate interpretation because of their limited spatial coverage, leading to a growing need to interpolate 2D seismic surveys to generate 3D data volumes.

The spark that started it Harmony came to life with a challenge that sparked a bold idea. When energy companies started to call for a low-frequency source in tenders, it quickly became clear that access to the necessary technology via third-party vendors was limited—and the associated costs were simply uneconomical. It forced a moment of […]
