Varel UK has signed a collaborative project with the University of Aberdeen to design and develop a new drill bit, which addresses the unique challenges of drilling in Resonance Enhanced Drilling (RED) mode.
Resonance Enhanced Drilling (RED) has been developed at the University of Aberdeen-based on research by applied dynamics Professor Marian Wiercigroch, based on theoretical mechanics.
The technique, which uses high frequency, to create resonances and to generate a controllable zone at the bit, improving significantly rate of penetration and reducing bit wear, as well as stress on the bit, has its roots in theoretical dynamics and fracture mechanics.
Jason Marchant, Varel UK District Manager North Sea, said: “There is a need to develop a new faster, cheaper way of drilling new offshore frontier fields that contain sections with chert or fractured granite/ conglomerates.
“The current methods with fixed cutter bits usually lead to uncontrolled energy distribution in these rock types leading to multiple and slow bit runs, or risks of roller cone bit bearing failures and lost time fishing cones.
“Together with OGIC and the University of Aberdeen, we’ve been examining a new concept that will ultimately result in the creation of a new hybrid drill bit with duel cutting mechanisms that will help overcome the challenges and result in a much more efficient and economical drilling process.”
The project will receive funding from the Oil and Gas Innovation Centre, for which this is the 40th project.
