One string, two pipes, three results
By adapting the fundamental design of the drill string, DualPipe overcomes commonly recognised drilling challenges. Using DualPipe, it is possible to access reservoirs previously considered challenging or impossible to drill conventionally.
The Reelwell DualPipe increases both productivity and recovery by overcoming common drilling challenges.
The unique, dual channel configuration allows drilling fluid to be pumped down the outer pipe annulus pipe while taking the returns to surface up the central pipe.
Increased reservoir access
Cuttings free wellbore
Offering superior hole cleaning and ECD control, the DualPipe allows for low energy drilling, i.e. low string RPM and flow rates.
Furthermore, DualPipe enables operators to drill beyond conventional boundaries, increasing the overall efficiency of drilling operations and reservoir recovery.
The standard drill pipe has been a key component in drilling operations since the 1940’s. Despite its daily use around the world, the core design has not materially changed.
As the industry is required to drill further in more complex or depleted reservoirs, we are challenged by:
Well control or fluid losses related to management of Equivalent Circulating Density [ECD] and limits downhole
Washouts, wellbore instability or hole cleaning issues
Increasing Torque & Drag, stuck pipe, lost in hole BHA’s and fishing operations

DualPipe Liner Drilling
DualPipe can also be used to enhance steerable liner drilling applications.
Enabling a step change in horizontal reach this DualPipe Liner Drilling has the same features and benefits as DualPipe, as well as:
