SYSTEMS AND METHODS OF POSITIVE INDICATION OF ACTUATION OF A DOWNHOLE TOOL.

摘要

Systems and methods of positive indication of the proper actuation of a downhole tool. One system includes a work string providing a flow path therein, a downhole tool coupled to the work string and having a body fluidly coupled to the flow path, an indicator chamber defined in the body and configured to retain a substance therein until the downhole tool is actuated, whereupon the indicator chamber becomes exposed and the substance is released into the flow path, and an optical computing device in optical communication with the flow path and configured to detect a characteristic of the substance in the flow path and communicate a signal when the characteristic is detected, the signal being indicative that the downhole tool has been actuated.
