GeoVista - Seismic Geophone

Digital: The Geovista borehole geophone system includes a downhole digital sonde and a compact digital interface unit at the surface, with no requirement for a seismograph. The sonde runs on single conductor cable on a standard logging winch. The digital interface unit at the surface has inputs for the downhole sonde, three surface geophones and the trigger. Collected data are outputted to a PC via the USB port. The acquisition software allows for data viewing and stacking. The generated SEG2 files can then be imported into most commercial seismic processing software.

Analogue: The analogue version has the same geophone in the borehole, but sends analogue signals to the surface. This sonde must be run on 4-core or 7-core cable and a surface seismograph is required. This option allows the geophone to be run in deeper boreholes.

Monitoring Geophone: Geovista can also supply an analogue monitoring geophone.
