SEISMIC DATA
RAU-D’s at TNO’s workshop
IMAGE: PASSIVE SEISMIC SURVEYS (ICELAND &
PEEL REGION)
Based on RAU-D units (fully digital remote acquisition unit)
Each unit is connected to a 3 component accelerometer
Each unit has its own internal data storage
Each unit has a GPS receiver for positioning and
time synchronization
Each unit has a Wi-Fi transmitter/receiver for communication
Central Acquisition unit (with wireless connection tot units)
External File server (multiple TB’s large)
3/4G communication with office

DESTRESS: SOFT STIMULATION
Impacts of variety of stimulation techniques on well performance on different
reservoirs:
Hydraulic stimulation
Radial Jetting
Thermal stimulation
Chemical stimulation
Looking for test location in the Netherlands!
