2.1 Importing Seismic Data (SEG-Y)

Seismic is the backbone of structural interpretation. Beyond the Built-In Tutorial Once you’ve finished the

  1. Right-click the Seismic folder in the Input pane.
  2. Select Import > Seismic > SEG-Y.
  3. Crucial Step: Petrel will ask for a Coordinate Reference System. If you don't know your CRS, ask your data manager. For the Gulf of Mexico, use NAD27 UTM Zone 15N. For the North Sea, use ED50 UTM 31N.
  4. Click "Apply." A seismic cube will appear in the 3D window. Use the Settings (right-click the cube) to adjust the color map. Seismic > Color Map > Gray Scale is standard for amplitude data.

Troubleshooting & tips

  • Datum mismatches: always confirm depth/time datum and unit consistency before tying wells to seismic.
  • Start coarse: build the model with a coarser grid first to validate workflow, then refine resolution.
  • Keep a clean Workspace: use descriptive names and folder structure to avoid confusion.
  • Use Petrel logs and built-in validation tools after each major step.

1. Create a project and organize data

  1. Open Petrel → File → New Project. Name and save.
  2. In the Workspace, create folders: Data → Wells, Seismic, Horizons, Grids, Interpretations, Models.
  3. Import files:
    • Wells: Import → Well → LAS (map LAS columns to log mnemonics).
    • Seismic: Import → Seismic → SEG-Y (set sample rate and byte order if needed).
    • Horizons: Import → Model → Surface or Horizon (GOCAD/ASCII).
    • Tops: Import well tops table and link to wells (ensure depth datum matches).
