Abstract

A smart dart has a central bore and a collapsible annular protrusion extending radially outward from the dart body. The dart is deployed in a run-in configuration and actuated to a landing configuration to stop on a target seat identified by a control mechanism based on a seat count. The dart also includes a latch tool at a nose section and the central bore and the inner bore of the latch tool are aligned axially. A valve is installed in the central bore and a valve actuator closes the valve to seal the central bore for pressure isolating the wellbore downhole from the wellbore uphole the valve when the dart lands on the target seat.
