Abstract

During the 3D seismic reflection survey within the project Integrated Seisrnics Oberpfalz 1989 (ISO89) the vibroseis source signals were recorded simultaneously with five threecomponent geophone borehole chain SEKANS or a single threecomponent borehole geophone, respectively, in the KTB pilot hole. The aim was to measure the traveltimes of direct waves in the depth range between 3220 and 3420 m in order to deduce spatial velocity inhomogeneities between surface and recording depth from traveltime residuals in the surroundings of the KTB. These data shall be used for improved static corrections if distinct from statics obtained by short refraction lines and first arrival analysis of surface data. A short description of the method is given which is based on approximation by least square fitted planes. Data examples and preliminary results are presented.
