The fault option enables interpretation of either a new fault or loading an existing one.
The new fault is inserted by selecting New option in the tree scene. The blank fault New fault 1 will be inserted as sub-element of Fault. Interpretation is then possible, on any inline/crossline/time-slice. After interpreting the fault, use Save to save the fault with appropriate name.
An example of a picked fault line on a seismic section:
If the option Load is chosen, the existing faults will be displayed in the scene.
Add attribute: Add a new attribute for fault element. Right click and choose 'Select attribute' to select the desired seismic volume. The attribute will be displayed along fault planes. The example line with interpreted faults in a 3D volume has been shown below. Note that the faults have seismic data displayed as an attribute along their planes.
Show histogram: Display the histogram of the current fault.
Properties: Set the Type, Size, and Color of the pick markers on the graphics area.
Display...: Display Fault planes, fault sticks. Display faults at section only to see the sticks on the displayed elements in the graphics area. This mode allows to pick new locations without being distracted by previously picked points throughout the survey volume.
Save/Save As: Either overwrite the stored fault by using option Save or store as new fault by using Save As option.
Lock: Lock the selected object. Prevents accidental removing, moving, or displaying data on object. After clicking on "lock" again (i.e unlocking), editing is enabled.
Remove: Removes the fault from tree. Removing an unsaved pickset will result in a complete loss of that pickset.
Note For Fault interpretation, please see the interpret faults chapter
