Once leads have been defined, detailed analyses of individual well locations must take place. [[:file:exploring-for-structural-traps_fig20-15.png|Figure 12]] shows an example of detailed structural mapping at the prospect level. It is a structural map on top of the Upper Triassic Nugget Sandstone, Ryckman Creek field area, Uinta County, Wyoming. Contour interval varies from [[length::100 ft]] (30 m) near the crest of the structure to [[length::500 ft]] (150 m) on the flanks. The dashed contours are the oil/water and gas/oil contacts.

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.
