Structural exploration: thrust belt example (view source)
Revision as of 22:03, 28 July 2014
, 22:03, 28 July 2014→Prospect and location
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 deformed in a pressure vessel at an effective overburden pressure of 15 × 10<sup>3</sup> psi (1 × 10<sup>5</sup> 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 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.
