Automated isolation system

A system comprising:

• a wellbore dart comprising a dart communication module;
• a first node comprising a node communication module and in communication with the wellbore dart via the node communication module;
• and
• a surface operator in communication with the first node, wherein the surface operator comprises one or more processors configured to perform operations for:
• deploying the wellbore dart configured for plugging at least one zone of a hydrocarbon well, the wellbore dart including a wellbore dart identifier;
• deploying a shoulder in a casing of the at least one zone of the hydrocarbon well, the shoulder comprising a unique shoulder identifier;
• receiving, by a node communication module of a reference node a communication from the wellbore dart for a period of time;
• identifying speed and location information of the wellbore dart by comparing a maximum communication distance associated with the reference node with the period of time;
• receiving, by a node communication module of the first node in the at least one zone, from the wellbore dart when the wellbore dart is proximate to the first node, the wellbore dart identifier, wherein the wellbore dart identifier is received from a dart communication module of the wellbore dart;
• performing a comparison of the unique shoulder identifier and the wellbore dart identifier to determine that the unique shoulder identifier and the wellbore dart identifier match;
• detecting an arrival of the wellbore dart at an intended location for the wellbore dart based on the determination that the unique shoulder identifier and the wellbore dart identifier match;
• stopping the wellbore dart at the intended location based on the detecting of the arrival;
• and
• activating the wellbore dart to plug the at least one zone of the hydrocarbon well at the intended location.

A tangible, non-transitory, computer-readable media having instructions encoded thereon, the instructions, when executed by a processor, are operable to perform operations for:

• deploying a wellbore dart configured for plugging at least one zone of a hydrocarbon well, the wellbore dart including a wellbore dart identifier;
• deploying a shoulder in a casing of the at least one zone of the hydrocarbon well, the shoulder comprising a unique shoulder identifier;
• receiving, by a node communication module of a reference node a communication from the wellbore dart for a period of time;
• identifying speed and location information of the wellbore dart by comparing a maximum communication distance associated with the reference node with the period of time;
• receiving, by a node communication module of a first node in the at least one zone, from the wellbore dart when the wellbore dart is proximate to the first node, the wellbore dart identifier, wherein the wellbore dart identifier is received from a dart communication module of the wellbore dart;
• performing a comparison of the unique shoulder identifier and the wellbore dart identifier to determine that the unique shoulder identifier and the wellbore dart identifier match;
• detecting an arrival of the wellbore dart at an intended location for the wellbore dart based on the determination that the unique shoulder identifier and the wellbore dart identifier match;
• stopping the wellbore dart at the intended location based on the detecting of the arrival;
• and
• activating the wellbore dart to plug the at least one zone of the hydrocarbon well at the intended location.
