Faults Overview

Create and manage faults using the Faults tab in the Control Panel. In Insight, there are two categories for fault items: Faults and Unassigned Fault Sticks.

There are two ways to pick faults in Insight:

  • Create a new fault item and immediately pick sticks for that fault (see Picking Faults)
  • Pick unassigned fault sticks and later combine them into faults when the structure becomes more clear. (see Working with Unassigned Fault Sticks)

You can define faults in the:

  • Map View
  • 2D Line View
  • IL/CL View
  • Arbline View
  • 3D View.

Managing faults

Now that you have created faults, you can manage them from the Fault tab, and by using the right-click context menu in views.

For quick and simple operations such as editing or deleting fault sticks, the context menu allows you to do it without leaving the view window (see Context Menu (Fault)).

At any time, you can also assign fault sticks to another fault or unassign a fault stick. Unassigned fault sticks will then be categorised in the Fault tab under "<<Unassigned Sticks (TWT/TVD) for [user]>>" (see Assigning/Unassigning Fault Sticks).

Fault display

Faults can be displayed in various views.

  • In section views (i.e. IL/CL View, 2D Line View, Arbline View), you can view the fault sticks that you have picked.
  • In 3D View, faults can be viewed as fault traces or as a computed fault surface.
  • In Map View, you can see fault intersections with the particular horizon or time/depth.

Note: In section and 3D views, when you navigate away from the location where you picked the fault, but still intersecting with the computed surface, the interpolated fault stick appears as a dashed line.

For instructions on how to view the faults in Map View and 3D View, see Viewing Faults.

Creating polygons from faults

Fault polygons can be generated from fault intersections with a particular horizon. This is useful to remove fault surfaces from the associated horizon.

Fault polygons are generated in the Polygon tab. For more information, see Using Fault Polygons.

Import/export faults

Insight allows import and export of faults in various formats. By default, faults are exported in the GeoQuest IESX format (.dat file).

For a comprehensive list of formats accepted for all objects in Insight, see Formats accepted by Insight for import and export.

If you are exporting from Insight to import into Kingdom, see What format of faults can I export from Insight for importing into Kingdom? in the FAQ section.
