Abstract

The heart of the Integrated Seisrnics Oberpfalz 1989 experiment
(ISO89) is a 3D seismic survey with a subsurface covered
area of 19.1 km* 17.85 km and the KTB borehole at its
centre. The brute processing by the DEKORP Processing Center
(DPC) at Clausthal resulted in an envelope-stacked data set
that is used for a preliminary interpretation. Several strong
reflections are addressed and mapped in 3D. The results are
presented in form of time contour maps. For the depth conversion
several velocity models are discussed and compared.
The depth _ conversion itself is realized by a map migration of
the interpreted horizons (SATTLEGGER 1986). The true 3D geometry
for several horizons is presented as well as the depth
they will be encountered in the KTB borehole.
