Reelwell Drilling Method (RDM)
Reelwell introduces a new drilling method that challenges the limitations of conventional drilling.
- The method secures accurate pressure management and improved well control through closed loop fluid circulation, making it especially attractive for Managed Pressure Drilling (MPD).
- The system configuration additionally represents substantial potential for pushing present limitations in Extended Reach Drilling - ERD - through hydraulic Weight on Bit (WOB).
- With all circulation being confined in the dual drill string, the new method may push existing deepwater limits through riser less drilling.
Technology - The method is based on concentric Dual Drill String closed circulation system. For increased safety, a Dual Float Valve and a Piston secures fulltime pressure control during drilling and pipe connections.
The Piston prevents the annular fluid from being lost. The Piston also provides the down hole hydraulic Weight On Bit (WOB) for increased reach when drilling horizontal sections. Drill cuttings are removed from the wellbore just behind the drill bit and routed back to the surface via the inner string, securing clean hole conditions.
