Abstract
Imaging beneath and within volcanic rocks is a longstanding challenge within seismic imaging. This problem is particularly acute in NW Europe, where volcanics affect a significant area of potentially hydrocarbon bearing formations. Using workflows developed over the course of several years and based on the results of synthetic and real data experiments a demonstrable uplift in seismic imaging quality is achieved. The results demonstrate the benefit of detailed velocity models built using Dynamic Matching FWI (DMFWI) and Common Offset RTM (COR) tomography together with more traditional ray-based methods. These velocity models provide interpretational insights as well as imaging uplift. A selection of results from real and synthetic datasets are used to demonstrate the results.
