Year: 2019
Region: UK North Sea, West of Shetland
Water depth: 1,082 m
Final inclination: 0.20 degrees
CAN-ductor (pre-installed)

Neodrill’s engineering team designed and developed a 32"x20” CAN-ductor for the Cambo appriasal well to determine if the CAN could established strong well load capacity under extremely soft seabed conditions in deep water.


Installed at a water depth of 1,082 m, and a final inclination of just 0.20 degrees, the project was successfully carried out under challenging weather conditions.


Colin Higgins, Wells Manager at Siccar Point commented ‘the CAN provides great inertia to the operation. When the rig arrives on location it can wake up the transponders, run the 17 ½” assembly from the derrick and drill to approximately 840 m in the first 36 hours.’

As the conductor is installed prior to rig arrival, the CAN-ductor typically removes 2-4 rig days per well and alleviates the need for the heavy lifting of tubulars. “The top-hole section of each well has very high levels of time and cost uncertainty for deep water drilling.  As the CAN-ductor eliminates this completely, it was a key selling point for us” said Colin.

Explaining the reason the CAN-ductor was selected, Colin said “It was due to the total value offered by the CAN and not an individual benefit in isolation.’ As well as cost savings and increased safety measures, there are also substantial environmental benefits to the technology. The environmental impact of the CAN-ductor is between 21 – 44% less than that of a conventionally drilled well for top hole activity. CO2 emissions in particular are decreased by 32%*.
