9-6 Exercise: Creating a Normal Fault
When you create faults in the Strat Column Editor, you are basically just making a catalog of faults that you can use later as you interpret. For this reason, you may find it useful to create several reverse faults and several normal faults at the same time.
• In this chapter, you’ll learn about these and other techniques as you continue to build your interpretation.

Overview
In this chapter, you’ll learn to
Cross Section is used to examine well-to-well relationships and to interpret faults and surfaces between wells. • Interpretation in Cross Section involves

Defining Faults
Recall that you can create faults as you interpret in Correlation, you
CAN create faults as you interpret in
Cross Section, and you can first create the faults in the Strat Column Editor.

Chapter 9: Interpreting Cross Sections and Editing Maps
• StratWorks generates fault grids to help you interpret cross sections, and uses fault polygons to prevent contouring through fault zones.
• create fault segments • edit surface grid intersections • generate fault grids and use fault grid intersections as an
interpretation aid • draw fault polygons in MapView based on the apparent fault

Strat Column Editor: Re-visited
In this chapter, you return to the Strat Column Editor to create the faults for use in Cross Section Interpretation.
In this exercise, you use Strat Column Editor to create a normal fault that you will interpret in Cross Section.

Interpreting Cross Sections
Do Lithology and Sand/Shale calculations. Rebuild structure and isochore maps based on completed interpretation. Refine the interpretation by interpreting faults in maps and cross section.
(1) creating and editing fault segments (2) generating and editing fault grid intersections (3) editing surface grid intersections derived from
heaves indicated by your cross section interpretations • use fault polygons to eliminate contouring through fault zones • edit contours.

Training Workflow
Column Faults
Faults are defined by
• name • fault type (normal or reverse) • color • line type • line width • fault status (active or inactive)
The fault namo a given fault is the same for all interpreters working in the project.
