Register here for the EAGE Workshop on Quantitative Geoscience as a Catalyst in a Carbon Neutral World, 31 May–1 June.
This workshop will showcase workflows and innovations in quantitative geoscience that are serving as a catalyst to realise these Net Zero ambitions, creating an immersive learning environment where participants can exchange ideas, challenge the norms, and listen to the experts to put ideas into practice. Check out the full technical programme here.
Our chief geophysicist Tom Rayment is part of the line-up—he’ll be presenting his talk titled “Full waveform seismic imaging: drastically reducing project lifecycle.”
Tom’s presentation details:
- Wednesday, June 1, 2022
- 2:30–2:55 pm UTC+08:00
- Pavilion Hotel, Kuala Lumpur, Malaysia
Presentation abstract:
Full waveform inversion (FWI) is a well-established tool for velocity model building as part of a conventional seismic processing and imaging workflow. However, recent advances in multi-parameter FWI have shown the technique is able to estimate many parameters, including reflectivity.
This FWI imaging approach uses the raw field data as input and requires little to no processing effort. It uses the parts of the wavefield (primaries, multiples and ghosts) that are typically removed from the data during a conventional workflow to generate high-resolution images of the subsurface.
The reduction in processing effort means the FWI imaging approach is primarily constrained only by compute and it is therefore possible to generate results in a fraction of the time compared to legacy methods. These higher resolution images generated in a shorter timeframe allow for better decision making and reduce risk.
