Physical models, such as those in [[:file:exploring-for-structural-traps_fig20-16.jpg|Figure 13]], that display structures similar in shape to natural, prospect-scale, thrust-related structures can provide insight on the overall geometry of the prospect and the location of zones of high strain (high [[fracture]] density?) within the structure. These insights can be useful in determining optimal well locations.

These models were constructed of originally planar layers of limestone, sandstone, and granite. They were [[Deformation|deformed]] in a pressure vessel at an effective overburden pressure of 15 × 10³ psi (1 × 10⁵ kPa). The top view is a photomicrograph of a model that simulates a thrust ramp. The bottom view simulates the hanging-wall geometry produced by movement along a series of bedding-parallel and ramp segments of a thrust fault.

Data on deformation mechanisms, such as fractures and how they affect reservoir properties, are obtained by integrating [http://www.merriam-webster.com/dictionary/outcrop outcrop] fracture data and laboratory estimates of fracture aperture. This integration allows for a direct calculation of fracture [[porosity]] and fracture [[permeability]] for the reservoir.
