This installation will be not open for the 2nd call.

Host Institution:

TNO, Princetonlaan 6 + 8, 3584 CB Utrecht, The NETHERLANDS

The facility is mobile and can be deployed anywhere in the world.

Description:

The mobile seismic array allows TNO to acquire their own seismic data which fits their position as an independent research institute. The equipment can be applied for different domains (Carbon Capture and Storage, Geothermal, Energy storage and production), and to evaluate new technologies. The set-up of the mobile seismic array currently consists of 64 self-contained stations that can operate both stand-alone basis as well as in an array. Therefore, the station spacing and layout of the network is flexible and can be tailored for the specific target to be addressed. Seismic data can be acquired both continuously and periodically and data is wirelessly transferred from the stations to a data server. The wireless capabilities of the seismic array allow fast data acquisition and enables rapid mobilization and deployment of the array. The system consists of Sercel Unite acquisition units coupled to an integrated three component (xyz) digital accelerometer (DSU3-428). The accelerometers have a broad frequency response ranging from approximately 0-800 Hz and are therefore able to record seismic waves in a broad range of frequency, making it suitable both for active high-resolution seismic surveys, and for earthquake and noise monitoring. The acquisition units can operate without external power supply up to ~10 days without recharging the batteries.

State of the art:

The mobile seismic array allows acquisition of accurate and continuous seismic data, both to accurately monitor subsurface processes and to evaluate new production strategies. TNO has broad experience with the operation of permanent seismic arrays and analysis of both passive and active seismic data. The seismic array has a flexible character, such that it can be used both for continuously acquiring passive seismic data to monitor earthquakes and subsurface processes, as well as for acquiring active seismic surveys for subsurface characterization studies. Furthermore, the seismic array is suited for field conditions (rugged and water-proof), and easy to deploy in the field. The scale of field deployment of the seismic array is flexible, with a depth of investigation ranging from approximately 100 m to 5000 m, depending on the local site conditions.
