Publication number: 20160053557Abstract: A torsional isolator (200, 300, 400) designed to reduce vibrations and shock experienced by electronics used during directional drilling is disclosed. The torsional isolator allows the drillstring electronics to oscillate at a slower rotational velocity than the data acquisition rate of associated sensors, such that the sensors record an average value of the azimuth heading thereby allowing for a higher accuracy measurement of the azimuth heading. The sample rate of the sensors is such that the sensors maximum error is reduced by the torsional isolator, as the output angular displacements are lower than the input angular displacements.Type: ApplicationFiled: May 1, 2014Publication date: February 25, 2016Inventors: Gerald P. WHITEFORD, Keith R. PTAK, Mark R. JOLLY, Gregg CUNE
