Abstract
Techniques for plugging at least one zone of a hydrocarbon well are disclosed herein. The techniques include methods for deploying a wellbore dart configured for plugging the at least one zone of the hydrocarbon well, receiving, by a first node, location information indicating a first location of the wellbore dart, receiving, by a second node, location information indicating a second location of the wellbore dart, and detecting, an arrival of the wellbore dart at an intended location for the dart to plug the zone of the hydrocarbon well. In some aspects, the method further includes sending a command to a firing module of the wellbore dart, the command effective to cause the wellbore dart to plug the zone of the hydrocarbon well. Systems and computer-readable media are also provided.
