How do I transfer an on-the-fly horizon to Petrel?
To transfer an on-the-fly horizon (e.g. TWT in depth, extracted amplitudes) to Petrel, first output the values to a new horizon.
This example shows how to transfer TVD values from on-the-fly depth-conversion to Petrel.
Note: Ensure a velocity model is configured for depth conversion (see How it Works: Time-Depth Conversion). The Petrel link must be connected to transfer horizons and/or faults (see Insight and Petrel Overview).

Use horizon maths to output the depth values to a new horizon.
- In the Map View > Operations tab, choose Horizon Maths.
- Add a horizon row.
- Use the default symbol: 'h1'.
- Select the TVDSS property.
- Use the formula: h1
- Click Calculate.
- Click Create
- Rename the new horizon, e.g. “TVD Result”
Push the new horizon to Petrel using the link.
Send to Petrel

- In the Horizon tab, right-click the horizon: “TVD Result”.
- Select Send to Petrel.
