Abstract:
Example methods and apparatus to determine and use wellbore diameters are disclosed. A disclosed example method comprises positioning a downhole tool in a wellbore, counting a number of rotations of a motor used to cause the downhole tool to contact a surface of the wellbore, and determining a diameter of the wellbore based on the number of rotations of the motor.
