Workshop Description

Recent major workshops have been focused around the advancement of FWI technology. In contrast, this workshop will concentrate upon the practical application and utility of FWI from the viewpoint of the asset team at all stages of the E&P cycle.

Early successful applications were principally in the area of improved depth imaging, often beneath shallow heterogeneous overburden. Newer, and perhaps more significant applications include: pore-pressure prediction, shallow hazard identification, reservoir characterisation, accurate depth conversion, direct interpretation of high-resolution FWI volumes, imaging salt-affected and other complex datasets, preconditioning for other forms of high-resolution seismic inversion, and correction of amplitudes prior to AVO and related analyses. Workflows that combine tomography and FWI have also become more common and more intertwined.

The workshop will feature case studies of successful FWI applications, industry overviews outlining current practice and likely future directions, and technology developments that are likely to lead to new applications and new workflows. The workshop will attempt to answer the question “when, how and why should I apply FWI to an asset for my company?”.
