Abstract
The present invention presents a laser mandrel () capable of being installed in the production string, in a position below the ICVs valves (and), to be used in a first moment aiming at preventing the formation of scale in the ICVs valves (and), and, in a second moment, for the removal of scale from the production string (). The laser mandrel () of this invention is provided with fiber optic cable (), electrical cable (), collimators (), and laser diodes (). It can be applied to prevent damage to well strings with electric intelligent completion, in case there is a failure in the chemical injection system installed in the string. It also makes possible the improvement of the technique aiming at the inhibition of inorganic depositions. Furthermore, it has a significantly lower cost than the conventional squeeze and/or removal, because once it is installed in the string, it allows the management of scale.
