Information meeting about 3D seismic surveys on South Lolland
On Thursday, December 5, 2024, CarbonCuts invited to its third public meeting – again in the cozy setting of The Factory Lodge, Holeby Climate Center, which has become a regular base for us.
Even though it was in the middle of the Christmas rush, the turnout was great. Over 60 participants, including many local farmers, turned up to hear more about the upcoming 3D seismic mapping that will be carried out as part of Project Ruby in February 2025. The survey will be the largest of its kind in Denmark and requires meticulous planning. Therefore, the meeting was an important opportunity to inform residents about what to expect and to answer their questions.
Geology: A detailed look at the underground
Exploration Manager and Geologist Charlotte Laurentzius gave a brief introduction to CarbonCuts and how we as a company want to contribute to the green transition by storing CO2. She then explained the purpose of the 3D survey:
“We already know from previous seismic surveys that the subsoil of South Lolland has relevant geological layers that are necessary to establish a storage facility. With 3D seismic, we can get a much more precise picture of how the layers are structured and how they are connected. This is important to assess whether the area is suitable for safe CO2 storage.”
Charlotte also described how 3D technology builds on previous 2D surveys and provides a more nuanced understanding of the subsurface structure.
How the survey is carried out
Kasper Lundvig, Project Manager at Geo, went through the practical aspects of the survey, which is carried out in collaboration with French seismic experts from S3:
“We are using specialized vehicles that create mild vibrations to map the subsurface. The work will take about a month and covers a large area. We make every effort to minimize inconvenience and try to adapt to individual needs where possible.”
He also explained the importance of the vibration-detecting geophones and encouraged participants to give their consent for the installation:
“The more geophones we can place, the better the data we get and the more accurate the results will be. We expect to deploy over 50,000 geophones in the area.”
A valuable dialog with the local community
The presentations were followed by a Q&A session focusing on the technical aspects of the study, timeline and impact on the local community. We really appreciate the constructive dialog and the many relevant questions that make us better able to plan and execute the survey with minimum inconvenience.
As a cozy ending in the midst of the Christmas bustle, we offered mulled wine and apple slices etc. Several participants also chose to give their consent on the day. We are grateful for the interest and openness shown by the local community towards CarbonCuts and Project Ruby, and we look forward to starting the 3D studies in February 2025.
