WATER SEISMIC

115 and 235 meter cables are used in fresh and sea water.

475 meter cable is used up to 350 meter water depth.

Geomap has 3 boats for small and bigger operations on sea. With the variety of our hydrophone cables, we can offer water seismic from small rivers to 350 meter water depth. 

The method is built up on registering the seismical waves that refracts from the geological layers which attributed with different velocities.

A prerequisite for applying this method is that the seismic velocities increase as the depth increases.

In water seismic surveys, we use special  water bottom cables with hydrophones and preloaded shot points. In shallow water and moderate sediment thickness, the 115 meter cable is used with 5 meter hydrophone distance. For more challenging surveys, a cable with active length of 235 or 475 meter is being used.
