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:

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 technology

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

With wired drillpipes, real time data from wells in any location can be presented and shared instantly, this facilitates real-time decision making at the rigsite and in town, and results in cost efficiencies.



Data challenge - Geosteering quality is limited, resulting in reduced production and recovery

By delivering high bandwidth logging and drilling telemetry of 56 kb/s, DualLink offers a real step change in visibility by supplying high-resolution real-time data & imagery. This means drilling decisions can be made instantly and accurately, without sacrificing drilling efficiencies to accurately place the wellbore in the optimal location.



Power challenge - A heavy reliance on inefficient solutions to deliver power downhole, such as litihium batteries or turbines downhole

By giving service companies power downhole from surface via the braid in the drillpipe, DualLink removes the need for batteries or turbines. Eventually, this will result in BHA tools without battery carriers or turbine assemblies: reducing BHA lengths and removing complexity.



Reliability challenge - No reliable method for high bandwidth communication downhole

Current BHA to surface communications depend on 0.5-6bps (bits per second) mud-pulse or E-Mag communication technologies: not dis-similar to Morse Code bit rates. Acoustic technologies offer higher data rates in the 30-50bps range, but require repeaters and can suffer from drilling noise downhole. Downlinking to tools downhole requires flow rate or RPM adjustments or sometimes the dropping of RFID tags or balls into the drillstring. Wired pipe offers a 56,000bps high bandwidth bi-directional hardwire link between surface and 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

Design of the current BHA tool technologies require limited life batteries and rotating or pulsing mechanical devices to operate and send data uphole, both of which limit the operating envelope and longevity of tools and drilling runs. Wired pipe systems have also struggled with connector reliability challenges in the past. DualLink’s ability to send power via the drillpipe from surface to downhole removes the limitations and mechanical reliability concerns of downhole tools. The connector design of DualLink is robust, rig proven and field replaceable. DualLink can be treated like an ordinary drillpipe. Due to its open system, it easily integrates into a rig.



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.
