Abstract
N-034 CHARACTERIZATION OF 4D-GEOPHYSICAL DATA USING A NONLINEAR INVERSION ALGORITHM A. ABUBAKAR P. M. VAN DEN BERG and J. T. FOKKEMA Centre for Technical Geoscience Delft University of Technology Mekelweg 4 2628 CD Delft The Netherlands Introduction Characterization of time-lapse 3D seismic data also known as 4D seismic is based on a difference image of the subsurface from two comparable surveys denoted by the reference state and the monitor state respectively. Both states are separated by a certain time span. Then from this difference observation conclusions are drawn with respect to the change of the medium which can be related
