The Mesa Verde outcrop: Seismic modeling, processing, and interpretation
- Inst. Francais du Petrole, Rueil-Malmaison (France)
For a realistic geological model a 2D numerical elastic modeling is carried out. The objectives is, first, a better understanding of the information content of reflection seismic data and, second, to provide synthetic data for testing and evaluating the efficiency of processing and inversion techniques under known conditions. Of particular interest are the small-scale heterogeneities in view of reservoir delineation and characterization. The geologic model is constructed from the Campanian cross-section of the Mesa Verde outcrop (Colorado, USA). A subsurface seismic model buried in a 1D background medium is defined from the 2D Mesa Verde geologic model by assigning P-wave and S-wave velocities and densities to each geologic facies. This seismic model is used as input for a fully elastic seismic simulating a realistic marine survey of 280 shots. The synthetic seismograms are calculated by a finite-difference method. The data are processed in a conventional way; then a target-related post-processing is performed including stratigraphic inversion. Finally, a geologic significance is given to waveform and amplitude variations in the estimated P-impedances.
