Exclusive video: Integrated auto-driller reduces weight-on-bit fluctuations

Heave compensation enables drilling in harsh environments by keeping the bit at a constant position in relation to the seabed. Traditionally, a crown-mounted compensator (CMC) can decrease drilling performance due to friction in the system. Niels Meissner, product technical manager at National Oilwell Varco, discussed the benefits of an active CMC used in conjunction with an integrated auto-driller at the 2013 IADC Advanced Rig Technology Conference last week in Stavanger, Norway. In this exclusive video with DC associate editor Joanne Liou, Mr Meissner explains how an auto-driller can help to reduce weight-on-bit variations and achieve consistent drilling performance.
