ABSTRACT:
Methods and related systems are described for downhole positioning of sensors such as accelerometers, gyroscopes, tiltmeters and geophones. The sensor or sensors are mounted within the spherical rotor of a spherical motor such that the device can be actively positioned in one or more orientations by activating the spherical motor.
