In-situ strain data from the Groningen gas field published

Good news!  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

Thanks for attending the first EPOS-NL annual meeting

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.

EPOS-NL on Youtube

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.

Open call for EPOS-NL Facility Access

Another call is open from 9 June to 16 July to get free of charge access to top EPOS-NL research facilities in the Netherlands, notably: 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 the Petrophysics Lab at Delft University of Technology Capabilities include CT scanning, triaxial compression testing, ring shear (friction) testing and analogue modelling of tectonic processes, including a wide range of surface scanners and cameras. Access can be remote (send in sample analysis) or physical (personal visit), depending on developments in corona restrictions, the requirements of the facility to be accessed and/or your wishes.
