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.

Techniques for mitigating magnetic sensor errors are contemplated. In some aspects, the disclosed technology provides a method for reducing measurement errors in a directional module of a drilling system that includes steps for: receiving a current measurement from a current sensor, wherein the current measurement is associated with electrical current received at the current sensor via a first conductive branch and a second conductive branch, receiving a field measurement from a magnetic sensor, and associating the current measurement from the current sensor with the field measurement from the magnetic sensor. Systems and machine-readable media are also provided.
