Abstract:
A method and system for completing cementing operations in a subterranean well with a wiper plug assembly includes delivering the wiper plug assembly into a casing, the wiper plug assembly having a wiper plug body with a circular cross section and a resilient wiper element that engages an inner diameter of the casing string. An inclination of the wiper plug assembly is measured in three dimensions with an accelerometer assembly and an azimuth of the wiper plug assembly is measured in three dimensions with a magnetometer. The inclination and the azimuth of the wiper plug assembly are delivered to a control unit in real time. An inclination of the wiper plug assembly is determined in real time. The inclination of the wiper plug assembly is delivered to an earth's surface in real time with a transmitter of the electronics package.
