Swiss Geo Energy is pleased to introduce a new video series that explores the complexities of geophysical campaigns and the steps of data analysis and interpretation that follow. The series focuses on the GeoCogen Eclépens project from last November.
Episode one: Why choose a geophysical campaign?
Join Andoni Dominguez, Head of Geosciences at Ad Terra Consultancy, our provider, as he outlines the reasons for choosing geophysical campaign solutions in our geothermal projects. This episode provides an overview of the technical and strategic aspects that guide our operations.
Geophysical campaigns are essential for effectively mapping subsurface geological formations and understanding their potential for energy extraction.
Episode two: Understanding geothermal data processing
In this episode, Andoni Dominguez, Head of Geosciences at Ad Terra, walks us through the complex process of processing seismic data within the GeoCogen Eclépens project.
Andoni discusses how seismic data is transitioned from acquisition to processing. He explains the importance of reducing noise, organising three-dimensional signals, and using well data to calibrate seismic images accurately. These processes are essential for ensuring that our interpretations of the underground formations are as accurate as possible, feeding into our drilling decisions.
Episode three: 3D Geological modeling for geothermal applications
This episode features Andoni Dominguez, Head of Geosciences at Ad Terra Consultancy, who presents the progress of the GeoCogen project in terms of the advantages of 3D seismic data over 2D data and explains how this information is used in geothermal projects.
Discover how the shift to 3D seismic data helps our understanding of geological structures. Join Andoni as he walks us through integrating seismic data with well logs to create detailed and accurate 3D geological models. These models are pivotal for precisely characterising geothermal resources, focusing on parameters such as brine flow rates and temperature.
Episode four: Insights from a Field Supervisor during a geothermal data acquisition campaign
This episode features Desiree Petrilli, Database Analyst at Ad Terra Consultancy and Field Supervisor, during the data acquisition campaign in Eclépens, who shares insights from the GeoCogen Eclépens project.
Discover a field supervisor’s role and daily challenges in geophysical campaigns for geothermal energy. From safety meetings to coordinating field teams, Desiree emphasises the importance of precision and teamwork in capturing high-quality seismic data.
The transition mentioned in the video, from hands-on fieldwork to data processing, underlines the critical role of field supervision in enhancing our understanding of geothermal resources.
Episode five: The reasons for selecting Eclépens for geothermal exploration
In this episode, Aleksander Aramovicz, our lead geologist at Ad Terra Consultancy, discusses the geothermal energy prospects of Eclépens, Switzerland. Using advanced seismic data and information from historical wells, our team has modelled the subsurface in 3D, revealing high temperatures at 2000m depth from a 1970s well that underscore the region’s energy potential.
This project is about more than electricity; it’s also about supplying heat to the local heating network. The unique 3D seismic data gathered during the geophysical campaign allows us to get a new geological understanding of the area, benefiting both our project and broader geological knowledge.
Episode six: How identifying geothermal well targets
In this episode, Martina Cervelli, our dedicated geologist at Ad Terra Consultancy, takes you through selecting the optimal site for geothermal exploration.
By analysing historical drilling data and naturally occurring faults in the subsoil, we develop a static geological model that serves as the foundation for dynamic geological and thermal models. This data-driven approach integrates geology, geophysics, and engineering disciplines, helping us identify target reservoirs and potential drilling trajectories.
Our primary focus is on two significant rock layers, with ages ranging from 247 to 145 million years. These layers, rich in limestone, anhydrite, dolomites, and other lithologies, present promising opportunities for geothermal energy extraction.
Series overview
This video is the first step in a series crafted to enhance your understanding of the post-geophysical campaign phase. In the upcoming episodes, we will explore the data interpretation and analysis for the GeoCogen Eclépens project in greater depth.
We invite you to watch the first episode and follow the series over the next weeks as we explore the scientific processes behind the scenes.
