A well marker is used to record the depth in a wellbore at which the wellbore intersects an identified horizon (conformable, unconformable or intrusive) or fault. Marker depths are identified during well log analysis and correlation. Markers are an input to subsequent modeling workflows such as Stratigraphy, 3D Structure and 3D Grid.

Custom format (*.)

Using this file type you can import markers from custom column-formatted files. During import you specify which data item is represented in which column.
