The use of digital outcrop models (DOM) in reservoir analogue studies has widely spread out in recent years. The objective of this workshop is to discuss different achievements in virtual outcrop geology, and to bring them more in line with practices in oil and gas companies. Two approaches are generally proposed for digital outcrop modelling: lidar and photogrammetry. Advancements in the development of new technologies for digital outcrop acquisition, data treatment, and DOM interpretation will contribute to significantly improve the understanding and modelling of complex reservoirs.
Even though several software for managing 3D geospatial data have been created during the last twenty years, the emerging 3D virtual world provides incredible opportunities to the current generation of geoscientists for teaching and for making geological virtual outcrops popular and accessible. To make these techniques obvious references for geoscientists, at least two important requirements have to be considered:
(1) providing a software for fast and easy modelling and visualization of virtual outcrops, and
(2) easing the extraction of meaningful geological data from virtual outcrops.
DOMs are an invaluable resource to understand reservoir architectures. Their offer many advantages: collection of data from otherwise inaccessible areas, access to different angles of view, increase in possible measurements, attribute analysis, fast rate of data collection, and of course training and communication.
The main application fields for such models and their interpretations are reservoir modelling, especially when using geostatistical approaches. Outcrop models can actually provide realistic values for parameters of variogram-based and object-based methods or training images for multipoint statistics. Outcrop data can also be used as a basis for synthetic seismic and fluid flow modelling or to provide large and robust datasets for Discrete Fracture Network (DFN) modelling for example.
The objective of this workshop is to review the current state of the art in the use of 3D Digital Outcrop Models in the industry and the link with other fields such as geomatics, augmented reality and learning. We aim to motivate and encourage cross-disciplinary discussions among scientists and engineers focusing on recent developments, and to share the different approaches relative to both acquisition techniques, data treatment and use in subsurface reservoir modelling workflows.
