How to Setup a 3D Seismic Time Interpretation



What is GVERSE Geophysics?

  • GVERSE Geophysics is a new, intuitive and easy-to-use seismic interpretation system with powerful 3D visualization and interpretation capabilities. GVERSE Geophysics enables geoscientists to execute end-to-end workflows for basic interpretation and more advanced geophysical tasks.

How to Setup a 3D Seismic Time Interpretation?

  • In GVERES Geophysics, select File > New Interpretation.
  • Name the interpretation and select Time Domain option, then click OK.
  • From the menu bar, under Seismic tab, select 3D Seismic Data Manager to add the preloaded 3D seismic survey.
  • Click Add adjacent to the 3D Survey Name box. Browse the Trace File Name.
  • Click Next and Finish to close the 3D Seismic File Load Wizard dialog box.
  • Highlight Moosehead in the 3D Survey Name box and highlight the Version Name file in the box below.
  • Click Info to view the details of the seismic survey, then select Seisworks Grid Definition.
  • Click OK to close the Information for Seismic File. Close the Interpretation Manager.
  • From the menu bar, Click Wells > Add Wells and Formations to add wells to the interpretation.
  • Ensure the “Add wells only within seismic extents” check-box is selected.
  • Select required Source and click Next
  • Select one by highlighting or all formations by clicking on the double arrow (>>)
  • Click Next to close the Well Data Load Wizard dialog box. Main Map View is updated showing the wells.
  • Select Horizons from the menu and select Horizon Manager to create new horizon.
  • Click Add and name the Horizon. Then click OK
  • Create multiple horizons from the Formations Tops association option in the Formation tab > Formation List. Highlight preferred formations and click create horizon.
  • Click Formation Annotations to make adjustments accordingly.
  • Right-click on the seismic survey and select Active Display Properties.
  • In the Active Display Properties dialog box, select the Wells tab and then click Filter Options button.
  • Highlight both checkboxes with velocity surveys and the highlight wells box and click OK.
  • Click OK to close the Active Map Display Properties dialog box.
  • Select a Well and press Shift to active its velocity survey.
  • From the well list menu, select velocity survey in the component tab. Activate/deactivate velocity survey.
  • Open an inline or crossline. At this point, wellbores do not display on the seismic section.
  • Select Interpretation > Settings. Add in the interpretation name, and a value for datum elevation and replacement velocity. Click OK.
