The paper describes investigations of parameters such as spurious resonance, natural frequency and coupling, which influence the high-frequency response of standard geophones. Coupling factors are determined along a survey live to demonstrate their v

1st EEGS Meeting.
During the last ten years seismic methods have lost much of its interest among all geophysical methods. Shallow investigations related to environmental problems are often made more efficiently using non seismic methods.

The large amount of information carried by the seismic signal can only be brought into play for seismic interpretation if geophones are able to follow the movement of the ground faithfully. This means that the bandwidth of the transfer function of th

It has long been recognized that fracture systems in rocks can significantly influence the flow of fluids in the subsurface. Geophysical fracture characterization techniques based on seismic anisotropy and related shear-wave splitting have been under

Comparison of both synthetic and field data shows that considerable suppression of correlation noise can be achieved with the Combisweep technique and with the Encoded Sweep Technique. In the first technique, the spectrum is shaped by superposition o

In many areas correlation noise has become a serious problem because of the high dynamic range of more than 60 dB between the strong first arrivals and the weak reflection events arriving several seconds later. Several efforts have been made to reduc

It has been known since the beginning of reflection seismics that several disturbing events seen in seismic records are caused by waves with S-wave velocities instead of P-wave velocity. When using dynamite and recording with vertical geophones these

Effective noise reduction of single-sweep recorded data is achieved by application of a velocity filter process on a decomposed vibrator pattern. This technique promises high resolution results with a minimum effect on signal characteristic. A compar

The characteristic and information content of a seismic signal depends considerably on the bandwidth of the signal. The Vibroseis system gives the possibility of selecting a certain frequency range. This selection is mostly done in the field by visua
