Workshop 1 Digital Outcrop Modelling: From Subsurface Applications to Virtual Field Trips

Date:

8 Sep 2024

Time:

09:00 - 17:00 EEST

Room:

Karuselli (Floor 0)

Convenors:

Jon Blickwede (Teyra GeoConsulting LLC, USA) David Hodgetts (VRGeoscience Limited, UK)

Overview

Digital Outcrop Models (DOMs) are precise three-dimensional digital representations of rock outcrops created from images captured by ground-based or drone-mounted sensors. These georeferenced models enable digital interpretations and integration with other geospatial data for applications such as outcrop analogue studies and virtual geological field trips.
The morning session of the workshop will cover topics such as data acquisition, processing techniques, visualisation strategies, digital interpretation, data integration, and case studies. The afternoon session will feature a hands-on course on digital outcrop modelling.

Participant profile

The ideal audience for this workshop would comprise:

Geoscientists and engineers who wish to use outcrops to refine subsurface models relevant to petroleum, hydrogen, and geothermal reservoirs, carbon dioxide sequestration strata, and aquifers. These professionals recognise the utility of outcrops in bridging the scale gap between seismic reflection profiles and well data, thereby providing critical insights into geological features that are not visible in typical subsurface datasets.
Geoscientists with a specialisation in stratigraphy and structural geology who use outcrop-derived data in their research. Utilising georeferenced DOMs, these geoscientists can make quantitative measurements—such as the orientation of strata, faults, and joints— from otherwise inaccessible portions of outcrops, increasing the size and statistical significance of quantitative field datasets.
Geoscientists that employ DOMs as a preparatory tool for optimising fieldwork plans. By utilising digital models, fieldworkers can prioritise key areas for on-the-ground investigations, thereby maximising the focus and efficiency of field visits.
Geoscientists interested in the digital preservation of significant outcrops for future examination and analysis. This is particularly pertinent for outcrops exposed during infrastructural developments like road and highway construction, which, especially in humid regions, are susceptible to rapid overgrowth of vegetation that obscures geological features.
Geoscientists who wish to create virtual field trips to important outcrops, offering a cost-effective and safe alternative to physical field excursions, and making field-based geoscience more accessible and inclusive.

At the end of this workshop, you will have an overview of digital outcrop modelling, and understand the basics of how to acquire, process, and interpret digital outcrop data.

Workshop 2 Transient Electromagnetic

Date:

8 Sep 2024

Time:

09:00 - 17:00 EEST

Room:

Tivoli (Floor 1)

Convenors

Esben Auken (TEMcompany, Denmark)
Anders Vest Christiansen (Aarhus University, Denmark)
Pradip Maurya (TEMcompany, Denmark)

Workshop Description

This is a one-day workshop on the Transient Electromagnetic Method (TEM) for mapping shallow geology, providing an overview of theory and applications.

Transient Electromagnetic (TEM) is not a new geophysical method, but it has not gained as much attention as other methods like imaging with multielectrode systems or small loop frequency domain electromagnetic methods. This lack of popularity is likely due to the complexity and high cost of both the instruments and the interpretation software. However, with advancements in technology over the last decade, these issues have become things of the past. The method is now faster, easier to use, and the cost of instruments has dramatically decreased. In this course, we will explain how the method works, how measurements are carried out, and how they are interpreted. We will focus on imaging deep groundwater layers and addressing shallow monitoring issues.

The workshop includes:

Basic understanding of how a TEM measurement works.
Linking a case target to the optimal measurement configuration
Measurements with single-site instruments, towed systems, and airborne systems
Field demonstration of a typical modern single-site instrument
Processing and interpretation of TEM data
Real-world applications using single-site and towed TEM systems.

Workshop 2 Transient Electromagnetic

Date:

8 Sep 2024

Time:

09:00 - 17:00 CEST

Room:

TBC

Convenor

Esben Auken ((TEM company, Denmark)

Transient electromagnetic is one of the few geophysical methods which has taken a leapfrog development in the last decay.

Workshop description

This is a one-day workshop on the transient electromagnetic method (TEM) for mapping of the shallow geology, overview of theory and applications

Transient Electromagnetic (TEM) is not a new geophysical method but it has not really gained as much attention as other methods like imagining with multielectrode systems or ground conductivity meters. The reason is probably that both the instruments and the interpretation software has been hard to use and very expensive. With all the new technology which has reached the world in the last decay this is the past and the method is now fast, easy to use, and instruments has dropped dramatically in price. In this course we will explain how the method works, how measurements are carried out and how they are interpretated. We will focus on imagining of deep laying groundwater and shallow monitoring problems.

The workshop contains the follow blocks:

Basic understanding of how a TEM measurement works
Linking a case target to the best measurement configuration
Measurements with single site instruments, towed systems and airborne systems
Field demo of a typical and modern single site instrument
Processing and interpretation of data
Cases solved with single site and towed systems.

Workshop 3 Hard Rock Physics

Date:

8 Sep 2024

Time:

09:00 - 17:00 EEST

Room:

Tarmo (Floor 0)

Convenors

Risto Kiuru (Rock Physics Finland Ltd, Finland )
Tuija Luhta (Geological Survey of Finland, Finland)

Workshop description

To fully understand and properly calibrate geophysical models, information on the physical properties of the rock mass is essential. Traditionally, literature and research on the topic has been quite heavily biased towards soft sedimentary environments. We propose a workshop on research and applications of rock and mineral physics in hard rock environments, specifically in the context of mineral exploration, mining and rock construction. Topics covered could include, e.g., laboratory testing of the physical properties of rocks and minerals, in situ physical property measurements, and application of physical property data to the development, calibration and interpretation of geophysical data and physical property models.

Participant profile

Researchers working on physical properties of rocks and minerals, both in the laboratory and the field
Students of the relevant disciplines
Practitioners using physical property data of rocks and minerals in their work
Practitioners that could benefit from using physical property data, such as those working with geophysical models or 3D physical property models

This one day “hands-on” short course goes through the practicalities of building a 3D conceptual model from scratch using AEM data together with other geoscientific data types by combining cross-sections, GIS maps and 3D visualization in the interpretation process. The focus is how to get the most out of your AEM data. In addition to the traditional manual modeling techniques, we will introduce and go through examples on how to utilize Machine Learning tools in the modeling process – including clustering algorithms and the Smart Interpretation method. We will also work with statistical methods and tools to evaluate and quality check the interpreted model with respect to the available data.

The course will be a combination of short lectures and exercises, and at the end of the day the participants will have touched base with the main principles behind building a 3D hydrostratigraphic conceptual model.

For the exercises in the course we will use the GeoScene3D software package – To be able to carry out the exercises, the course participants will get free access to the software during the course. The participants are required to bring their own laptops with a reasonable graphics card, see more on https://www.geoscene3d.com.

The course material will be made available to the course participants prior to the course.
