Workshop Description

This full-day workshop will cover all aspects of uncertainty related to geological models. Topics include model accuracy, model precision and the visualization and communication of these uncertainties for geological models ranging from detailed reservoir models to regional scale multi-purpose models.
The workshop is aimed at geoscientists and policymakers that deal with uncertainties, by bridging gaps between producing uncertainty information and understanding and using it.
The uncertainty in these models has different sources, ranging from uncertainties related to wells, i.e. metadata and interpretation, seismics, i.e. 2D or 3D, vintage, velocity model, fault model, property modelling, etc. But also even less quantifiable sources as geological knowledge used in the modelling process. Furthermore, what would be the best way to communicate these uncertainties, using statistical measures, diagrams, cross-sections?
In this workshop we start with a morning session for non-specialists by giving mini-lectures on accuracy, precision and visualization. One of the mini-lectures will be given by Prof. Florian Wellmann Ph.D. from RWTH Aachen University.
The EAGE Annual 2021 will be held in hybrid format, meaning that it will combine an in-person event with online components. However, please note that the workshop programme is in-person only and will not be streamed.

An illustration of different combinations of accuracy and precision that are also applicable to modelling. The more proximate to the desired answer (bull’s eye) means more accurate. Precision describes how proximate the points are situated to each other.
