The system can be modified to a low cost yet robust Analogue set up, for high temperature (200oC) surveys.

This mode of GeochainTM Operation is ideal for very hostile well deployment such as deep check shot surveys. The requirement of only the GSR tool and no other telemetry/electronic devices (Gamma tools optional) allows the GeochainSlimTM Analogue to be one of the most economic borehole seismic survey systems on the market.

Surface Control
The analogue system is controlled by Geochain System Panel GSP-1 (currently operates up to 16 analogue channels) and a DCP-2 Dual control panel which allows operation of up to 2 analogue satellites.  The GSP uses standard running ASL Acquisition suite.
