A sensor assembly includes a position measurement sensor, a slickline, and a processor. The position measurement system measures angular velocity of the sensor assembly inside a wellbore that extends in an axial direction. The slickline raises and lowers the position measurement sensor in the wellbore. The processor executes a series of measurement units including: an inclination measurement unit, a coordinate measurement unit, a depth measurement unit, and a data storage unit. The inclination measurement unit determines an inclination of the position measurement sensor. The coordinate measurement unit determines radial coordinates of the position measurement sensor. The depth measurement unit determines a real-time depth level of the position measurement sensor. Each of the inclination, the radial coordinates, and the real-time depth level are determined from the angular velocity. The data storage unit stores the measured values, including the angular velocity, inclination, radial coordinates, and real-time depth level.

A method may include obtaining wellhead temperature data from a wellhead coupled to a wellbore. The method may further include obtaining production data regarding the wellhead. The method may further include obtaining water cut data from the wellhead. The method may further include calibrating a production model for the wellhead based on the production data and the wellhead temperature data to generate a calibrated production model. The method may further include determining a predicted production rate of the wellhead using the calibrated production model, the water cut data, and flowing wellhead temperature data.
