The section describes how the derived Spectral Blueing operator can be applied to your data using the OpendTect plug-in. Application of the Spectral Blueing operator can be done in various ways. Please refer to OpendTect documentation for full details. For the purpose of this document, we will only describe a couple of the mechanisms which you could use. Now, depending on whether you wish to run a test or whether you want to process a complete volume or sub-volume read the respective sub-section below. Running a test first is a good idea as you will have the opportunity to quickly view the result of applying your Colour Inversion operator to a sample inline or xline before applying the operator to the entire 3D volume.
This is best achieved via the OpendTect "Attribute Set" dialog. If you haven't closed the "Attribute Set" dialog used to launch the SsbQt plugin, then it should still be somewhere on your desktop (possibly hidden behind other windows). At this stage you will need to select the operator to use. This is achieved by clicking the push button to the right of "Input Wavelet" label which will pop up a dialog with a list of available wavelets. Select the wavelet that was saved during the SsbQt analysis and design. The final step before running our test will be to give our attribute a name via the input field to the right of Attribute name label and click the button. Now, assuming that an In-line or X-line graphical element is displayed within OpendTect and that one of these items is selected as active, then it is very easy to see the effect of the derived Spectral Blueing operator by clicking the
icon within the OpendTect "Attribute Set" dialog. This will immediately apply the Spectral Blueing operator to the selected "Input Data" in the Attribute Set for the In-line or X-line graphic element currently displayed. Display will then be updated and, if it is visible in one of the scenes, you will immediately see the result. This is a very useful QC tool which will allow you to view the results of applying the derived Spectral Blueing operator to your data before committing to processing multiple 3D inlines (sub-volume) or the entire 3D seismic volume.
Application of the Spectral Blueing operator is achieved via the OpendTect attribute processing facility (see OpendTect documentation chapter 5 for details of how to do this). In brief, this can be achieved by either clicking menu item or clicking the
icon within the OpendTect main window. This will pop up the "Process" dialog.
