  • Traceability of cementing plug using smart dart
    Patent number: 11933142
    Abstract: An instrumented wiper dart configurable at the wellsite comprising any combination of a sealing member, a sensor sub, an electronics package, and a communication system; wherein the sealing member is cylindrical in shape, releasably coupled to the wiper assembly, and configured to sealingly engage the inner surface of a workstring. The sensor sub is release releasably coupled to the wiper assembly, and includes one or more sensors to measure a property of the wellbore environment. The electronics package is releasably coupled to the wiper assembly, configured to receive one or more data sets from the sensor sub, and transmit one or more data sets to the communication sub. The communication sub is configured to transmit the one or more data sets; and wherein the instrumented wiper plug is displaced down the workstring in response to a volume of fluid pumped from surface.
