A method of monitoring deformation and other characteristics of a casing or other tubular or cylindrical well equipment in a well traversing an underground formation, comprises:—providing a carrier rod having at least one recess extending along at least part of the length of the rod, in which recess an optical fiber assembly for monitoring strain, temperature and/or other physical parameters is arranged, which assembly is along at least part of its length bonded within the recess;—lowering the carrier rod and well equipment simultaneously into the well such that the rod is arranged in an annular space between the well equipment and the wellbore;—securing the rod at a plurality of locations distributed along its length to the well equipment; and—connecting the optical fiber assembly to an optical signal transmission and reception assembly for monitoring the physical parameters of the well equipment. |
