Abstract:
The present invention refers to a method wherein a test body is assembled in specific configurations to be submitted to testing in a conventional hydrostatic chamber. The method calls for assembling a test body that simulates cementing failures, the presence of stress anisotropy and a borehole of irregular geometry, by pressurizing said test body in a conventional hydrostatic chamber. The uniform forces are distributed circumferentially around a casing stream in a non-uniform way, simulating operating conditions that are as close as possible to reality, enabling an analysis of how the structure reacts in scenarios similar to actual conditions.
