An incorrect anisotropy in the Full Wave Inversion (FWI) velocity model leads to imperfect Common Image Gather (CIG) flatness. The main difficulty in the anisotropy estimation through FWI is the strong coupling with velocity. While FWI jointly updating velocity and anisotropy has been proposed ...

Seismic imaging is particularly challenging in the Middle East. The shallow geology is often characterized by strong velocity contrasts from layered sands and carbonates that create multiples and mode conversions. Capturing these velocity variations is essential for accurate imaging. While re-cent developments in full-waveform ...

The Intergovernmental Panel on Climate Change (IPCC) has just concluded its Sixth Assessment Report Cycle (AR6). The reports making up the AR6 provide the most comprehensive overview of the current state of climate change, its impacts and the adaptation and mitigation options that are ...

Screen opportunities using the latest North Sea seepage data results, which comprise more than 5,000 interpreted satellite-borne radar scenes to provide unrivalled insight into the nature and locations of hydrocarbon seepage across the entire North Sea.

The Cornerstone OBN data set delivers subsurface images of unprecedented quality in the most challenging areas of the UK Central North Sea, de-risking field development and near-field exploration.

Time-lapse seismic is now being used more frequently to assist reservoir development, prevent infrastructure damage or monitor geological storage. To better reveal true 4D signals while suppressing acquisition-related noise as a result of, for example, water velocity changes, source positioning errors etc., a new ...

Successful applications of full waveform inversion (FWI) to land datasets are far less numerous than marine applications, yet the development of dense, long-offset broadband acquisitions has presented promising opportunities. While challenges exist due to elastic effects, acoustic land FWI has been shown to provide ...
