Abstract:
1. A method of controlling a communication along a carrier, comprising: using the carrier to communicate electrical energy; positioning a communication linkage and at least one node at a subsurface location, the at least one node in the communication with the carrier via the communication linkage, the at least one node comprising: a control member to initiate an energy flow to the communication linkage, and a second control member to form a circuit that allows the energy flow to have a sufficient electrical energy flow to destroy at least a part of the communication linkage, wherein the at least the part of the communication linkage includes a consumable element, and wherein applying the sufficient electrical energy flow from the carrier transforms the consumable element into a disintegrated state to cause to non-reversibly terminating the communication between the carrier and the at least one node; activating the control member and the second control member using a controlled signal: destroying the at least the part of the communication linkage upon receiving the controlled signal; and using the controlled signal to said non-reversibly terminating the communication between the carrier and the at least one node.
