News Eve is the best moment to sum up the results and revise what was done in 2018. At this year we took part in more than 10 conferences and exhibitions where we were demonstrating the equipment we design and manufacture and presenting studies on technologies we currently develop. On the “GeoEurasia 2018” conference it was demonstrated G-Boomer for the first time. At this event it was also introduced a prominent idea on the simultaneous source technique that allows one to improve efficiency of seismic survey ...
