Electric CTD

E-CTD BENEFITS

Separates motor control from hole cleaning considerations

10 x power output vs existing motor technology

High torque capability (for drilling and PC pumps)

Hollow shafted for fluid transfer

Extended longevity (up to 500F)

Allows widest choice of drilling media

Immediate data feedback and high quality data link make the BHA ideal for under balance and closed loop drilling applications

Phase 1 of the project delivered a fully working prototype which made use of a submersible pump motor.  At 5.125" OD, this BHA was too large for most CT drilling applications.  However, the benefits of electric coiled tubing drilling were proven in a very practical sense.

Phase 2 is developing a fit for-purpose 3.125" BHA. The 2.5m long DC brushless motor is expected to deliver over 24HP at 500rpm and around 330ft-lbf of torque over the entirety of its 0-1000rpm operating range.

Phase 3 is designed to produce a fully operational, 'all-electric' 3.125" BHA.  This involves the addition of traction tools, geosteering capabilities and LWD tools.
