Visit us at the SEG Conference in Dallas starting 16th Oct to 21st Oct 2016. Our digital borehole geophone BGK1000 will be presented by Geotomographie GmbH at the GISCO booth #924. Its a good opportunity to meet our colleague Sonja Mackens and to discuss applications of borehole seismics. See you soon.

BGK1000 just back from a 20 days mission in Western Australia.
NAGRA News
A lot of seismic measurements were conducted by DMT at the begin of 2016 in Zurich, Switzerland using their new BGK1000-H sondes.

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.
BGK1000 Z-Wave
DMT measurements with BGK1000 showed excellent results in geophone Z-component.
BGK1000 User Manual Rev. 2
The new revision 2 of the BGK1000 User Manual is now online. It contains well illustrated documentation about setting the right clamping force and choosing the right clamping arm.
BGK1000 order of two systems to be shipped August 2015
Two BGK1000 systems with hydrophones are in production for the German client DMT.
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.
