An optical sensing member within the anullus zone of a well is disclosed, which sensing member determines the level of debris in the well. When debris accumulates within the anullus zone, said sensing member returns a signal indicative of the level of such debris within the zone. The optical sensing member may include an optical fiber and/or any known optical sensors configured to determine strain, pressure, shape, force, and/or temperature.

L'invention porte sur un élément de détection optique à l'intérieur de la zone annulaire d'un puits, lequel élément de détection détermine le niveau de débris dans le puits. Lorsque les débris s'accumulent à l'intérieur de la zone annulaire, ledit élément de détection renvoie un signal indicatif du niveau de ces débris à l'intérieur de la zone. L'élément de détection optique peut comprendre une fibre optique et/ou n'importe quel détecteur optique connu configuré pour déterminer une contrainte, une pression, une forme, une force et/ou une température.
