You can open the well markers classification sheet to view and edit the markers data in a spreadsheet.

Apart from importing wells into a session (see Importing a Well), you can also load the wells that have been saved in the project database into a session.

Snap allows you to fine-tune a horizon so that it is positioned consistently on a specific part of the trace waveform (positive peak, negative trough, zero-crossing increasing, or zero-crossing decreasing)

The Horizon Maths operation allows you to conduct mathematical and logical operators on one or more horizons and to create a new horizon based on the result. Simple formulas (+, -, *, /, ^) can be used along with one or more horizons.

The Ghost operation creates a copy of the selected horizon at a time or depth distance that you provide.
