The BlackBox® HD is a memory mode vibration logging tool that can be placed anywhere in the BHA including the drill bit. The tool measures tangential acceleration and angular position that result in axial, lateral and torsional vibration and RPM values. Through application of extensive measurements knowledge and experience, the BlackBox HD can help deliver custom solutions to drilling challenges such as stick-slip, whirl, and borehole quality, optimizing drilling performance and reducing well delivery costs.
