Seismic Exploration 2
Seismic Exploration 2 : Seismic exploration uses seismic waves of different type (mostly reflected, refracted and converted body waves) of usually higher frequencies between some 1 to 100 Hz and thus shorter wavelengths and higher spatial resolution than commonly recorded and analyzed in earthquake seismology. These high-frequency seismic waves are typically generated by controlled seismic sources such as explosions, vibrators, and airguns and recorded by geophones or hydrophones. S. e. aims at detailed imaging of layered, folded and faulted structures in the Earth crust. Commercial s. e. is usually termed seismic prospection and aimes at finding structures with potential for exploitable natural deposits of oil, gas, acquifiers etc.in the uppermost crust
