The analysis of seismic reflection amplitudes for reservoir characterisation or, more general, for the lithological interpretation of reflection data has become a standard approach in exploration geophysics. However the nonuniqueness of the interpretation of amplitude anomalies in P-wave sections has shown the need for shear-wave velocity information to permit a reliable lithology discrimination. In the paper Processing of PS-reflection data applying a common conversion-point stacking technique by Tessmer et al. 1990 a field data set has been presented which has been generated using three conventional P-wave vibrators as source and in-line horizontal geophones as receivers. This technique of shear wave data acquisition is relatively simple and inexpensive compared to techniques using shear-wave vibrators, because it can be done simultaneously with the routine P-wave recording.
