Abstract

An apparatus for mitigation of torsional noise effects on borehole measurements. The apparatus may include a conveyance device; a sleeve having a sensor section, the sleeve rotatably disposed on the conveyance device; a sensor having at least one component disposed on the sensor section; and a driver coupled to the conveyance device and configured to rotate at least the sleeve sensor section. The driver may rotate the sleeve sensor section independent of the conveyance device. The driver may rotate the sleeve sensor section at a preset substantially constant rotational speed. The sleeve may include at least one arm configured to selectively lock the sleeve to a surface in the borehole. The driver may rotate the sleeve sensor section during measurement by the sensor. The driver may selectively couple the sleeve.
