Lithologieerkundung fuer den Tiefenaufschluss mit seismischen Methoden (LITASEIS). Abschlussbericht. Bd. 1 Datenakquisition und Reflexionsseismik

Seismic data is usually processed and interpreted for structural information. The aim of the LITASEIS project was to develop and to test methods for a lithological interpretation of seismic data, and to summarize the experience in guide lines. A central part of the work program was the acquisition and processing of a shear wave survey in Northern Germany, where complex near surface structures are encountered. Comprehensive investigations on near surface properties and on acquisition and processing parameters were carried out. An integrated interpretation yield a seismic shear wave section down to base Zechstein. Further investigations on absorption anomalies, anisotropy, surface waves, period lenths and refractions aimed at getting additional information for lithological interpretation of surface recorded data. The investigations on borehole measurements were based on previous basic research projects (ASW and LIPS). Algorithms were developed for the estimation of absorption, for modelling and matching of microseismograms as a function of porosity and permeability and for blocking of logs and realistic VSP-modelling. Volume 1 comprises investigations on data acquisition, the influence of near surface laters and reflection seismics.
