The complexity of vibrator baseplate-ground interaction measured with a thin-film pressure pad and a downhole tool
When a seismic hydraulic vibrator sweeps, it emits the signal we desire as well as a series of harmonics due to the non-linear behaviour of the hydraulic system and the baseplate-earth contact. The phase of the fundamental component of the transmitted signal also varies significantly from that of th...
