How do I perform an amplitude extraction between two horizons?
An amplitude extraction between two horizons can be done from the Map View (see Horizon Operations in Map View - Amplitude Extraction).
Alternatively, you can also perform an amplitude extraction between two horizons by using a sculpted volume. Follow the steps below for a different approach to amplitude extraction between two horizons.
Note: You should first familiarise yourself with how to perform an extraction along a single horizon (see the "Mapping and Attributes" tutorial video, or the Single Horizon Amplitude Extraction section in the User Manual).
Create a volume sculpting process
- From the Control Panel, open the Process tab.
- In the Process tab, click on the Add icon (+).
- Scroll down and double click on Volume Sculpting.
- Type a name for the process and click OK.
Sculpt volume between horizons
- In the Details Panel, select the input volume to sculpt at Volume.
- At Top and Bottom Horizon, choose the top and bottom horizons that you want to extract between (and your data volume).
- At Constrain to area, select a polygon/probe to constrain the sculpting to the area covered by the polygon/probe (see Creating a Polygon in Map View, Creating a Probe).
- Select the Exclude traces where a horizon is missing check box to remove traces where one or both horizons are not present. By default, areas of the volume not covered by the horizon(s) are unmodified.
As a result of this process, a sculpted volume is available in the Volume tab.
Set amplitude extraction window
- From the Control Panel, open the Map View.
- At Horizon, select either the top or bottom horizon.
- Click on the spanner icon beside the horizon property.
- Choose the sculpted volume from the previous step as the Volume to use.
- If you chose the top horizon, set your Below amplitude extraction window large enough to cover the entire sculpted volume (or the Above window if you chose the Below horizon).
