EBN presentations EAGE-GET 2025
EBN was once again well represented at the EAGE Global Energy Transition Conference & Exhibition (EAGE GET). The conference provides a platform for professionals to share knowledge and collaborate on innovative solutions to urgent challenges in the energy transition. This edition featured a robust technical program that integrated knowledge, bridged disciplines, and aimed to chart a path toward global decarbonization. Several EBN experts gave presentations on:
Cross-sector learnings from the Netherlands. Seismicity Risk Management in Geothermal & CCS
Authors: G. Thürschmid, S. de Vries (EBN)
Geothermal and CO₂ storage share differences and similarities, offering opportunities to learn from each other. Seismicity is a common subsurface risk. This presentation compares how both sectors address seismic risk (covering regulation, guidelines, and monitoring) and highlights two Dutch initiatives: a Seismic (Hazards) and Risk Analysis for geothermal projects and the development of a guideline to evaluate the risk of loss of geological containment and induced seismicity for CO₂ storage in the Dutch North Sea (Project CO2NSEIS).
The Porthos project: how to manage CO₂ injections in a heavily depleted gas field
Authors: M. Bouts, J. Hild (EBN)
This presentation discusses the measures taken by the Porthos project to safely inject CO₂, ensuring the temperature does not drop below 0°C. Key steps include: first injecting gaseous CO₂; insulating the offshore pipeline; and replacing the inner casing. Finally, injection is scheduled using the Calysto-OPM software tool. Afterwards, extensive pressure and temperature measurements are carried out in the wells.
Assessing regional validity of NMR core calibration using SCAN Amstelland-01 & De Bilt-01 geothermal exploration wells
Authors: J. van den Broek, S. Ganguly, A. Janszen, M. ter Borgh (EBN) & M. Kozlowski (Halliburton)
An important focus for geothermal wells is assessing reservoir permeability. The SCAN program collected data from the BLT-01 and AMS-01 wells, including NMR log measurements for porosity and permeability. However, quantitative interpretation also requires calibration with core data. This study examines whether NMR core calibration from the Rotliegend Group in Amstelland-01 can be applied to De Bilt-01, about 30 km away. The results provide insight into NMR log behavior and influence strategies for future wells.
Integrated approach to characterize geothermal reservoir flow potential: an example from De Bilt-01
Authors: S. Ganguly. A. Janszen, J. van den Broek, M. ter Borgh, L. de Groot (EBN) & M. Koslowski (Halliburton)
This study presents the integration of all available well data, from core to log to well test. These data are used to determine reservoir permeability at different scales. In addition, the effect of reservoir heterogeneity, measurement uncertainty, and upscaling uncertainty around permeability is investigated in the SCAN well De Bilt-01. This workflow will then also be tested on other SCAN well datasets.
Screening the Dutch gasfields on suitability for hydrogen storage
Author: Silke van Klaveren (EBN)
This presentation focuses on the screening of Dutch gas fields for suitability for hydrogen storage carried out by EBN. It also discusses the study EBN conducted for KGG on the boundary conditions for an underground hydrogen storage (UHS) demonstration project in the Netherlands. The findings show that several suitable fields are located in the industry-rich western part of the Netherlands, in the provinces of Noord-Holland and Zuid-Holland, where demand for UHS in gas fields is expected to emerge first.

Impact of abandonment pressure on hydrogen storage in onshore gas fields in the west Netherlands

Core workshop Panterra – SCAN project
Author: A. Janszen (EBN)
In collaboration with Panterra Geoconsultants, the SCAN project hosted this workshop showcasing the full potential of core data in evaluating, understanding and predicting geothermal reservoir performance. Participants had the unique opportunity to examine cores from the Slochteren Formation, retrieved from the SCAN boreholes De Bilt-01 and EDE-01. Up close and hands-on, participants explored how depositional environments and diagenetic processes influence flow potential in geothermal reservoirs. The workshop sparked lively discussions around permeability measurements across multiple scales.

Minimum stress testing XLOT in seals of Geothermal SCAN wells: Methodology and models
Author: M. Hettema (EBN)
As part of the SCAN wells geomechanical data program (Janszen et al., GET 2024), extensive logging, coring, and testing were carried out. This presentation highlights the determination of in-situ minimum stress in seals, based on results from the first three wells at multiple depths. These findings are compared with post-drill 1-D models to enable extrapolation to other geothermal projects. The insights help ensure safe drilling, prevent out-of-zone injection, reduce seismic risk, and assess thermal fracturing that could impact system safety and long-term productivity.
