Deep Structure Profiling and Multichannel Seismic projects

Summer 2010: 2D /4Ń contract and testing operations using seismic bottom nodes were carried out in the Barents Sea in co-operation with JSC MAGE on board the research vessel "Geofizik”. Duration of this expedition was 60 days.

1. Survey system DSP: one step distance for node’s placement was 10 km; one step distance for shooting was 250 m; recording parameter 60sec/2msec. Sea depth 80-160 m. Profile’s length 350 km;

2. Survey system MCS: one step distance for node’s placement was 100 m; one step distance for shooting was 7 to 8 m; recording parameter 3sec/1msec. Sea depth 40-50 m. Profile’s length 2 km;
