New Tools & Methodologies

New Tools

Five protoypes geophysical systems are being developed and validated within the project – mainly under WP2 – New Instruments:

Unmanned Aerial Vehicle - UAV

A modular-based, geo-referenced UAV system has been constructed together with a novel broadband EM data acquisition system to be mounted on it.

Developing partners: AMKVO and Geological Survey of Sweden

Helicopter-based deep penetrating TEM - HTEM

The system markedly enhances the deep of investigation (DOI) while lowering the cost of collecting one line km data.

Developing partners: SkyTEM and Aarhus University

Electric Seismic Source - e-vib

The e-vib is used to vibrate the ground and thus allowing to map the subsurface using echoes to create visuals, in a manner similar to ultrasound technologies. It is is fully electric and broadband in frequency, making the images more accurate and higher resolution, and it can be used underground.

Developing partners: Seismic Mechatronics, TU Delft

GPS time-system

the system mainly uses hydrophones communicating with the surface via ethernet cables and represents a cost- and time-effective modular digital acquisition system useful for both slim-boreholes and depths as 1500-2500 meters.

Developing partners: MicNordic AB and Uppsala University

Slimhole modular-based digital seismic-magnetic-temperature system

The system allows deeper penetration around boreholes; being also digital (EM noise free) it can also be used by non-expert geophysicists and hence more routinely employed.

Developing partners: Bitsim and Uppsala University

New Methodologies

New and adapted seismic and EM methods are being developed and validated mainly within WP3 – Advanced Subsurface Imaging and Modeling:

3D frequency and time-domain electromagnetic modeling.
Thin-sheet time-domain modeling and IP responses.
New solutions for near-surface problems and related deeper imaging improvements.
Generating additional data from sparse active-source seismic data with lower environmental impact. Scattering/diffractivity imaging, improved resolution depth imaging.
Using background seismicity for imaging, source-free imaging and characterization.
