Battery-operated position sensor assembly for wellbore intervention

A method to perform a plurality of measurements in a wellbore, the method comprising:

• measuring, via a position measurement sensor, an angular velocity of a sensor assembly extending inside the wellbore in an axial direction;
• raising and lowering, via a slickline, the position measurement sensor in the wellbore;
• executing, via a processor, a series of measurement units, the series of measurement units comprising:
• determining, via an inclination measurement unit based upon the angular velocity measured by the position measurement sensor, an inclination of the position measurement sensor inside the wellbore;
• determining, via a coordinate measurement unit based upon the angular velocity measured by the position measurement sensor, radial coordinates of the sensor assembly inside the wellbore, the radial coordinates defining a location of the position measurement sensor in the wellbore for a radial direction orthogonal to the axial direction;
• determining, via a depth measurement unit configured to determine based upon the angular velocity measured by the position measurement sensor, a real-time depth level of the sensor assembly inside the wellbore, and
• storing, via a data storage unit, a plurality of values, the plurality of values comprising the angular velocity, the inclination, the radial coordinates, and the real-time depth level of the position measurement sensor.
