Transforming the drilling industry
Driving forward a step change in drilling performance, DualLink will transform the drilling industry. As the only wired drillpipe to leverage digital telemetry, power and greater reliability downhole, DualLink meets the needs of both land and offshore drilling.
Benefits
DualLink re-defines the standard, enabling a step change in well construction to deliver predictable,
high-quality well construction.
By energizing the downhole BHA with data and power, DualLink’s benefits are three-fold:
Data
More efficient drilling and less NPT
With high resolution downhole data and imagery enabling instant decision making.
Well placement quality improved
With high bandwidth logging and
drilling telemetry of 56 kb/s.
Enables drilling automation
Operates on an open platform; totally independent and can be integrated with any software or tools.
Power
500W of power at depth
Removes the need for downhole power sources for the BHA: shorter tools with measurements closer to the bit, less moving parts and lower asset and operating costs.
Environment and safety improved
Removes batteries from the BHA
and the associated handling,
transportation and disposal.
Reliability
Robust field replaceable connectors
Can be handled like an ordinary
drillpipe & easily integrates into
existing rig operations
Unique braided-cable design Provides >800 transmission channels to deliver greater surface contact and inbuilt redundancy.
Key selling points
Efficiency / environment
Improvement of 15%
Increase in total recovery by 20%*

Developed with a focus on reliability
Designed for full and easy integration into a rig, the DualLink network has been built with redundancy at its core and the total cost of ownership in mind.
DualLink is turning on the lights for downhole and bringing drilling out of the dark.
DualLink integrates easily into existing systems and can be handled in the same way as a regular drillpipe. Designed for the future, the technology enables shorter bottom hole assemblies (BHAs). The shorter BHA facilitates the design and use of lower cost tools and allows all measurements to be taken closer to the bit at much faster data rates.
DualLink is an efficient and robust engineered solution. Its future-proofed design results in a reduced risk of component failure.
The technology is also a more environmentally friendly option, as lithium batteries are no longer required, and faster drilling results in less rig emissions per well.
The potential of a powered drill string
How does DualLink overcome current challenges?
Data challenge - Poor quality data results in low resolution downhole imaging, resulting in delayed decision making
Data challenge - Geosteering quality is limited, resulting in reduced production and recovery
Power challenge - A heavy reliance on inefficient solutions to deliver power downhole, such as litihium batteries or turbines downhole
Reliability challenge - No reliable method for high bandwidth communication downhole
Reliability challenge - No comprehensive solution for drilling and rig automation
The industry is quickly developing and adopting automation technologies, both downhole and at surface. However, to deliver a fully closed loop system, we cannot rely on the low bit rate and high latency telemetry from current MWD (Measurement Whilst Drilling) technologies. High data rate, low latency, bi-directional communications is essential to finally deliver an automated drilling system. Developed as an open platform, DualLink is totally independent and can be integrated into any software and rig / BHA system.
Reliability challenge - Downhole tools have limited longevity - no integrated solution
Reliability challenge - Drilling process is slow, labour intensive and inefficient
The introduction of the wired pipe moves the industry a step closer to an automated drill rig. This evolution will save time and money through fewer rig days and improve safety allowing experts to focus on value-add tasks and well control.
