| Summary: | after NMO has been applied. Direct comparison of and Buda correlate well with seismic events on the synthetic both sections display laterally varying amplitudes (surface Chalk and provided a clear image of the subsurface after compressional (P) and shear (S) wave data in a fractured depths. The top and bottom of the Austin Chalk reflectors on Gap, "Top-of-the-Austin-Chalk", "Bottom-of-theAustin-Chalk", Lancier Brinckman #1 well. The difference in depth between lithology. The P-wave and S-wave data selected for this locations 55 to 68). This region coincides with the high-oil migrating the DMO data. Major reflectors such as the Pecan moveout (NMO) correction applied in common midpoint (CMP) offset traces to true zero offset. Dip moveout (DMO) is a One of the major goals of seismic data processing is to present, or when velocities vary laterally, the normal- process that converts non-zerooffset data to true zero offset produce an accurate image of the subsurface of the earth. production zone (fractured zone). related DHf (direct hydrocarbon indicator) was seen in both reservoir can show whether amplitude anomalies on the P-wave section are associated with the presence of gas or change of sections. Comparison of both sections before and after DMO seismogram which was generated from the sonic log of the shows that DMO has helped imaging the fractures in the Austin sonic log depths are deeper than the P-wave seismic section stacking fails to convert even primary events on non-zero study were shot in Burleson County, Texas. After processing, the P-wave and S-wave sections were interpreted. No gas- the sonic log and the P-wave seismic section is small. The Unfortunately, when dipping events or diffractions are |
