DGG 2016 Münster

BGK 1000 is presented over 4 days in the exhibition of the 76. Annual convention of Deutsche Geophysikalische Gesellschaft in Münster, Germany, 14 – 17.03.2016.

Geotomographie rental and exhibition manager Rochus Souan and Clemens on the booth.

Günther Druivenga and Clemens talking about joint application with Günthers new surface vibrator source ELVIS.

Multilevel connector testet with 10 kN

Multilevel connector between geophone units is successfully tested up to 10 kNewton.

Test facility at TFH Georg Agricola in Bochum.



Measurements in Mechtersheim

Vibro measurements with GEOSYM shear wave vibrator ELVIS 3 and BGK1000 showed excellent results with 10 seconds sweeps from 20 to 80 Hz.

Results of geophone X-component,.

New ELVIS shear-wave vibrator in action.

Hydrophone completes BGK1000 to 4 components

The new hydrophone can be used in borehole sections where clamping is impossible. It has a flat frequency response from 10 Hz up to several kilohertz, see Data Sheet BGK1000-H.

The new geophone-hydrophone pair concept takes advantage of different signal properties of the recorded pressure waves. Downwave and upwave amplitudes are in phase when recorded by a hydrophone, and are in antiphase when recorded by a geophone.

New downhole correlation and stacking significantly reduces survey times


The new firmware add-on for BGK1000 performes correlation and stacking of sweeps directly in the Sonde, cutting Vibro survey times down to a half or less.


New firmware features:

  • 65 seconds sweep length (1ms)
  • 4 full sweep memories downhole
  • 16 full stacks of 65 seconds
  • downhole stacking
  • downhole correlation
  • noise monitoring
  • fast quality control

The new downhole correlation and stacking feature is available as add-on to new and existing BGK1000 systems.
