Abstract
In some embodiments, an apparatus and a system, as well as a method and article of manufacture, may operate to determine a value of strain, such as an equivalent plastic strain, in a perforated portion of a well by applying a set of draw-down pressures to the surface of at least one perforation tunnel in the perforated portion. The perforated portion, in turn, is modeled using stress components provided by a global field model that includes the location of the well, to set boundary conditions at the surface of the well. A well drilling process and a tunnel perforating process are modeled with element removal and pressure addition for the perforated portion. Additional activity may include operating a controlled device based on the value of strain that is determined. Additional apparatus, systems, and methods are disclosed.
