Abstract

Where large commercial investments are at stake, it is essential that geologic deductions be as soundly based as possible. For example, many fault traces are drawn on seismic sections solely on the basis of the viewer's perception of the geometry of events that can often be interpreted in more than one way. The geologist should be aware of what fault patterns are realistic, and what are mechanically or geometrically improbable. The following methods and principles assist in:

  1. Making geologically realistic interpretations in seismic profiles and cross sections based on well data.

  2. Calculating unknown variables such as extension, fault dip, fault throw and shape, and depth to sole out if some of these variables are known.

  3. Restoring a cross section to its original (predeformed) state by palinspastic reconstruction.
