Detailed Information

CAN - Conductor Anchor Node                                                                                                                                         

The advantages of the CAN technology:

- Pre-installation of the top-hole well section from a light vessel

- Provides lateral support in soft seabed formations

- Verified load capacity

- Fatigue management

- Excellent foundation for single subsea satellite wells

- Easier P&A operations

- Time and cost savings

- No cuttings generation and no cementing for conductor installation

- Risk mitigation

- Higher load capacities

The CAN (Conductor Anchor Node), NeoDrill’s base product, is in principle a combination of an especially designed suction 

anchor and a centrally placed pipe as a through going conduit. The suction anchor is used for pushing the centre conduit into 

the seabed and for providing wanted top support for the conductor. This novel and patented approach of installing a subsea 

wellhead foundation (similar to land operations' well "cellar") was developed in order to facilitate pre installation of conductors 

with light vessels and sub sea conductor driving. More than a dozen CAN installations have proven the practicality of the CAN 

approach.

CAN-ductor

The CAN-ductor is the next evolutionary development step based on the CAN technology. It combines all the technical 

benefits of the CAN system with the commercial benefits of a pre-rig installed conductor.

As for the CAN, the CAN-ductor is installed by vessel (anchor handler, offshore construction vessel) before rig arrival. This 

provides the usual verified results for the load capacity. The conductor is in place upon rig arrival, which together with the 

simplified P&A benefits provides cost savings of 2-4 rig days.

The CAN-ductor is NeoDrill's latest development intended for cost saving, operations simplification and for development of 

shallow reservoirs. A short conductor is integrated into the CAN in the workshop and installed as one package by a vessel. 

This clever combination also offers simplified P&A operations in addition to mitigating a series of common top- hole related 

risks. Significant cost savings are the main driver for its application in addition to unequalled capacity for shallow kick-off.

The CAN-ductor is installed from a vessel ahead of rig arrival. This removes the 36" (42") hole drilling, conductor running and 

cementing operations from the rig schedule. Consequently, the "environmental footprint" will be reduced.

The CAN consept offers unparalleled load capacities for single production wells, and easy integration of protection structures 

and pre-installation of flow lines, etc.
