Seismic inversion provides quantitative subsurface properties that are used across geological, geomechanical, and reservoir workflows. When applied consistently, inversion results improve model alignment between disciplines, support uncertainty-aware decision making, and strengthen drilling and reservoir management outcomes.
This session focuses on how seismic inversion results are used to improve downstream subsurface workflows and business decisions. Rather than discussing inversion methods in isolation, the emphasis is on the practical application of inversion-derived properties across geology, geomechanics, reservoir modeling and characterization workflows.The session will show how elastic and rock-property volumes from seismic inversion support more consistent geological models, reduce interpretation ambiguity, and improve property distribution away from wells.
Examples will demonstrate how inversion results are used to constrain geomodels, populate static and dynamic simulations, and support geomechanical assessments such as stress prediction and wellbore stability analysis.Rock physics plays a central role in enabling this value by linking inversion outputs to reservoir-relevant properties such as lithology, porosity, and fluid effects, ensuring meaningful use across disciplines.
The session will also reflect the increasing use of probabilistic and Bayesian approaches in inversion workflows, including methods to quantify subsurface uncertainty. It will demonstrate how this uncertainty can be carried forward into downstream models, allowing teams to evaluate risk, test development scenarios, and make more informed drilling and field development decisions.Overall, the session highlights seismic inversion as a practical and essential input to integrated subsurface workflows, demonstrating how its results directly impact operational and strategic decisions across the asset lifecycle.

The quality of seismic imaging has a direct impact on the reliability and accuracy of conventional seismic reservoir characterization. Over the last decade, Full Waveform Inversion (FWI) has revolutionized seismic imaging. It first established itself as an extraordinary velocity model-building tool capable of handling complex geological settings, and more recently it has emerged as a potential quantitative imaging technique.
Today, FWI can deliver high-resolution quantitative subsurface models that partially overlap with the resolution traditionally achieved through seismic reservoir characterization methods such as AVO inversion. This evolution naturally raises an important question: should Full Waveform Inversion and traditional AVO inversion be regarded as competing or complementary techniques?
In this dedicated session, we aim to illustrate and discuss the benefits, limitations, and perspectives that FWI can bring to quantitative interpretation, and to explore how it can best be integrated with conventional seismic reservoir characterization workflows — and vice versa.
