Seismic exploration system improvement
Patent
·
OSTI ID:6955570
This patent describes a seismic exploration system having geophone locations along a survey line with at least one geophone connected to separate circuits connected to corresponding terminals of a roll-along common depth point switch. A means is described for identifying a specific one of the geophone locations as the switch changes connections, comprising means for superimposing a signal outside the useful range of seismic energy signals generated by the geophones on the one of the separate circuits connected to the specific geophone location whereby the location may be identified on the changed connection side of the switch.
