1. A system for use in a well in a formation, comprising:
- a length of casing configured to reinforce a wall of the well;
a structure that is configured to deform with deformation of the casing, said structure being affixed to the length of casing at substantially the same radial position along the length of casing, whereby the structure and the casing have substantially parallel longitudinal axes; and
a sensing device that is configured to measure deformation of the structure, said device comprising a string of sensors wrapped around the structure such that the sensors are distributed along both the length of said structure and the perimeter of said structure.
