Abstract (en)

[origin: US2014076550A1] Optical analysis systems may be useful in detecting microannulus formation in a wellbore casing and remediating a microannulus. In some instances, a system may include a cement sheath disposed about and in contact with at least a portion of an exterior surface of a casing; and at least one optical computing device arranged coupled to the casing, the at least one optical computing device having at least one integrated computational element configured to optically interact with a material of interest and thereby generate optically interacted light, and at least one detector arranged to receive the optically interacted light and generate an output signal corresponding to a characteristic of the material of interest, the material of interest comprising at least one selected from the group consisting of the cement sheath, a displacement composition disposed between the cement sheath and the exterior surface of the casing, and any combination thereof.
