This module is deprecated. It is provided for legacy workflows only.
The Synthetic Horizontal Layers - Stack module generates a zero-offset (post-stack) synthetic seismic section representing up to five horizontal reflectors. Each reflector is defined by its two-way zero-offset travel time; the module places a Ricker wavelet at each reflector time and writes identical traces to an output SEG-Y file. All traces in the output are identical (there is no moveout — the section is fully stacked at zero offset). The result is a simple synthetic stack that can be used for algorithm testing, training, or as a reference dataset when developing processing workflows.
The module has no data stream inputs; all output is generated from scratch based on the parameters below.
This module does not require input seismic data. It generates synthetic zero-offset traces entirely from the specified reflector times and wavelet parameters.
The number of identical traces to write to the output file. Since all traces are the same (zero-offset, horizontal layers), this parameter simply controls the width of the output synthetic section. Increase this value to produce a larger dataset suitable for testing 2D or 3D workflows.
Default: 1600.
The output trace sample interval in seconds. This controls the temporal resolution of the synthetic. Use 0.002 for 2 ms or 0.004 for 4 ms sampling. Set this to match the sample interval of the real dataset you are benchmarking against.
Default: 0.004 s (4 ms).
The length of each output trace in samples. The total record length in time equals this value multiplied by the Sample rate. Ensure this is long enough to include all specified reflector times plus the wavelet tail. For example, with a sample rate of 4 ms and a deepest reflector at 4 s, set the number of samples to at least 1100.
Default: 2501.
The dominant frequency in Hz of the Ricker wavelet placed at each reflector time. Lower values produce a broader, lower-resolution wavelet; higher values produce a sharper wavelet with greater temporal resolution. Match this to the dominant frequency of the real data you are benchmarking.
Default: 15 Hz.
The full path and file name of the output SEG-Y file (.sgy or .segy) where the synthetic post-stack section will be written. Use the file browser to navigate to the desired output location. The file will contain all traces as a single SEG-Y dataset.
