Interactive Structural Model Editing (ISME) allows fast manipulation of salt or geobody velocity models without detailed reinterpretation of an entire seismic volume. ISME can be used to correct structural model issues or enable rapid, interactive structural changes to the model to facilitate an improved understanding of the velocity model for quick scenario testing. Updated velocity models can be used in localized seismic imaging workflows, common-image-point tomography or prestack depth migrations.
- Easy updating of existing velocity models with small structural updates and corrections
- Generating multiple velocity models involving changes of geobodies such as salt bodies for scenario testing with interactive depth migrations
- Interpretation of replacement structure using multi-Z interpretation, interpretation line segments, or data from industry-standard formats to honor true multi-Z values, creating a patch to either add or remove structure to the original salt or geobody
- Stitching or merging a replacement structure to the original model and adding or removing individual pieces of geobodies
- Merging multiple simple salt geobodies into a single geobody to build detailed and complex structures, or quickly adding sediment inclusion into a larger salt body
- Updating velocity models based on the newly modified salt or geobody structure
- Using a new velocity model with any Schlumberger application, including any Omega software depth migration algorithms and tomography or other plugins for the Petrel platform
