Examples
Before using our scripts with your own data, you may want to run them with the data presented in this section to make sure that everything is working properly. And even if this is not the case, the two seismic data presented here will be used to illustrate the results obtained with the developed codes.
You can find information about the data in the data repository. For reasons of storage space, the used files are not in the repository. However, you should place all data in your own data repository after downloading the main repository to your computer. Pay attention and check the names of the folders and files in your data directory, they must be exactly the same as those that appear in the scripts!
The codes discussed here were developed for two different seismic datasets. They use functions contained in the managing.py script, found in the toolbox repository, to make adjustments to the data headers. It is worth noting that the scripts discussed in this section were developed to make some necessary adjustments, such as those related to geometry. If you think it is not necessary to make changes to the header of your data, there is no need to use them and you can proceed to the toolbox repository. However, if your data need some header adjustments, the scripts should be adapted to your needs.
The data, as well as important information about it, can be obtained directly from the SEG Open data page. This is a prestack 2D land vibroseis dataset. The developed script makes necessary adjustments to several keywords in the header, as can be seen in the Figure 1, in addition to removing some unnecessary seismic traces.
As before, data and relevant information can be obtained here. This marine dataset was obtained in the North Sea. The script determines the x and y CMP coordinates from the x and y coordinates of the source and receiver. This information is then included in the header. Figure 2 shows the changes in the data header.
