Attrezzature

Refraction and Reflection Seismic Survey

  • Modular Seismograph, Geometrics Geode x2 = 48 channels, 24 bit, ultra-high resolution 20 kHz bandwidth (8 to 0.02 ms sampling), low distortion (0.0005%), low noise (0.2uV), stacking accuracy (1/32 of sample interval). expandable without limitations. Ultra-high dynamic (144 dB total dynamic range), with a band from 1.75 to 20.000 Hz; the minimum sampling of 20 microseconds allows the execution of surveys at high and very high definition.
  • Batteries of vertical geophones, with frequencies of 4.5 and 10 Hz Geospace, 14, 30 and 100 Hz Mark Products;
  • Battery horizontal geophones, (24), Geospace 10 Hz;
  • 3-D Time Lapse Surveys: 10 Hz, Dual Down-Hole System – Geotomographie.
  • Seismograph LENNARTZ (Mod. LE-3D/5S),  Ideal for seismic measures particularly for analysis H / V (Nakamura method); the frequency response, extremely stable from 0.2 up to more than 100 Hz, makes it the best marketing tool for analysis in the field of Seismic Survey.
