This isn’t exactly ‘news’, as this data portal has been online since 2020. But for those of you who had not yet seen it: EBN and TNO have jointly developed an excellent data portal for openly published data on pore fluid (formation) and lithostatic (leak-off) pressure data, pertaining to the Dutch subsurface (< 5 km; both on- and offshore). In-situ temperature measurements down to 5 km are also available. You can access the portal via the EBN data centre (see Pressure SNS data base), or directly via this link to the Spotfire interface. Go and have a look!
A new dataset has been published by the Nederlandse Aardolie Maatschappij (NAM), through EPOS-NL. This open access dataset constitutes photographs of core slabs (core-parallel slices) taken from the reservoir intervals of 67 cored wells in the Groningen field and surrounding areas.
The Groningen gas field is the largest gas field in Europe and has been showing seismicity since the 1990s. The approximately 200 meter thick gas reservoir is situated at ~3 km depth, and comprises Permian (Slochteren) sandstone from the Rotliegend formation. The reservoir has been cored extensively by NAM. Each core has been sectioned (cut vertically) and all sections have been photographed. The resulting photograph database allows for detailed inspection of sedimentological features of the Rotliegend reservoir of the Groningen Field. This dataset further includes a web-based core Image viewing tool developed in-house by NAM. This tool allows for scrolling through photos of individual wells with zoom-in functionality at different magnifications.
The third call for Facility Access was open from 10 March – 17 April 2022. We received 7 applications for access to the Multi-scale Imaging and Tomography (MINT) facilities at Utrecht University and Delft University of Technology, the ESL High Pressure and Temperature (HPT) Lab at Utrecht University, and the Delft Petrophysics Lab at Delft University of Technology.
In addition, EXCITE, a European network to provide access to a wide range in Microscopy and Tomography facilities also received many applications to get access.
It’s great to see that there’s so much interest for research facilities developed within EPOS-NL and EXCITE, and to welcome all these projects and collaborations that, without Facility Access, may not have been initiated!
- The ESL High Pressure and Temperature (HPT) Lab at Utrecht University
- The Petrophysics Lab (DPL) at Delft University of Technology
- The Multi-scale imaging and tomography (MINT) facilities at Utrecht University and Delft University of Technology
Capabilities include X-ray (CT) scanning, Scanning Electron Microscopy, micro-chemical mapping, triaxial compression testing and shear (friction) testing.
NB: this call, MINT is accessible for Netherlands-based researchers only. Researchers outside the Netherlands can apply for access to MINT via the next call of the recently launched EXCITE program, expected this Summer. The ESL-HPT lab and the DPL are accessible for researchers worldwide, including the Netherlands.

A new, 18 MEuro proposal was submitted to the Roadmap call for Large-Scale Research Infrastructure on 17 February 2022. The proposal for “EPOS-eNLarge” is aimed at delivering the infrastructure needed for state-of-the-art research into efficient and safe use of our subsurface, in relation to meeting the international climate goals. To that end, EPOS-eNLarge will provide the missing link needed to apply our understanding of micro-processes in the subsurface at the kilometer-scale where subsurface operations – and the effects of these – take place. It will further ensure that unique research data of the Dutch subsurface is made openly, and centrally accessible for future re-use, alongside other European data. EPOS-eNLarge is a partnership between the EPOS-NL institutes Utrecht University, TU Delft and KNMI and new partner TNO.
Have a look on the EPOS-eNLarge webpage for more details on this new proposal!
Distributed Strain Sensing (DSS) data from the Groningen gas field are now published at Yoda data services. On request from the Dutch research community DeepNL, EPOS-NL approached the Groningen field operator (NAM) to publish these data. These are unique data, describing compaction of the reservoir system during production of the seismogenic Groningen gas field.
The Groningen gas field is the largest gas field in Europe. Gas production in this field has led to seismicity and surface subsidence, both believed to be caused by compaction of the underlying reservoir sandstone. In 2015, the field operator (Nederlandse Aardolie Maatschappij – NAM) installed a fibre-optic cable in the Zeerijp-3a well, at a true vertical depth of about 2900 to 3200 m, i.e. in and around the gas reservoir. The Zeerijp-3a well is situated in the center of the field, where seismicity (<3.4 M) and subsidence (34 cm) are both greatest. This cable allows real-time, continuous, in-situ monitoring of compaction of the reservoir and over and underlying formations, through the Distributed Strain Sensing (DSS) technique. DSS data (strain-time-depth) obtained from October 2015 to August 2019 are provided by NAM, open access. The data were processed by NAM, as detailed in the reports accompanying the data. The data presented in this data publication were used and analyzed in the research report: “Analysis of and learnings from the first four years of in-situ strain data in Zeerijp-3A” which is provided along with this data publication and is individually, openly accessible at: NAM research reports.
On 16 September 2021, the first EPOS-NL annual meeting was held. With the theme “EPOS-NL: what’s in it for you?”, this day focused on the services EPOS-NL provides for research, notably:
- Free-of-charge access to Dutch research facilities
- Central data access
We look back on an inspiring day. We thank the lab representatives and EPOS-NL partners who presented at this meeting, Helen Glaves for giving an inspiring keynote talk on “Open science, why does it matter?” and well over 100 participants who joined the meeting.
Did you miss (part of) the meeting, or would you like to review some of the presentations you’ve seen? Many of the presentations given can be accessed here.
Recently, NWO developed a series of clips of currently operating, national programs within the roadmap for large-scale infrastructure programs, including EPOS-NL. Watch them now on Youtube!
The NWO national roadmap for large-scale research infrastructure aims to strengthen the scientific position of the Netherlands by encouraging the development and construction of large-scale research facilities.
The 2nd call for Facility Access was open from 9 June to 16 July 2021, for proposals to get access to the ESL High Pressure and Temperature (HPT) and Tectonic modelling labs at Utrecht University, the CT scanners of the Multi-scale Imaging and Tomography (MINT) facility at Delft University of Technology (TU Delft) and/or the Delft Petrophysics Lab at TU Delft.
In this 2nd call we received 13 applications, bringing the 2021 total to 31 applications, from all over the world. Successful applicants receive(d) the following services free of charge: lab/equipment use, technical support and scientific support for analyzing data for the duration of the access period. EPOS-NL expects to grant 22 to 25 out of the total 31 applications, fully in the spirit of sharing research facilities and open science!
The next call for EPOS-NL Facility Access will be open in Q1 2022. To stay informed about future calls, subscribe to our newsletter here:
- the ESL High Pressure and Temperature lab at Utrecht University
- the ESL Tectonic modelling lab at Utrecht University
- the CT scanners of the Multi-scale Imaging and Tomography (MINT) facility at Delft University of Technology
