PROGRAM 1 DRILLING TECHNOLOGIES

OBJECTIVEProgram 1 will extend the capability of Coiled Tubing (CT) drilling so it can drill deeper, is steerable and delivers the highest quality sampling. Coiled tubing technology promises drilling at 1/5th the cost of conventional diamond drilling and thus has the potential to drive a revolution in mineral exploration whilst delivering significant health, safety and environmental benefits. Drilling tasks that are more suited to conventional drilling will also be tackled by the MinEx CRC, developing technologies for optimising the performance and increasing the productivity of Reverse Circulation (RC) and diamond drilling techniques.

PROJECT 2: COILED TUBING DRILLING FOR DEFINITION OF MINERAL DEPOSITS

LEADER: Soren Soe

PARTICIPANTS: Anglo American, BHP, Epiroc, LKAB Wassara, MRIWA, South 32, Curtin University, CSIRO, UniSA

RESOURCES: $2.17M (cash) + $2.10M (in‐kind)


To improve the sample integrity of CT drilling to that of diamond drilling, then develop the ability to drill multiple deviated holes, up to 1000 m reach, from a single pad, to within 10 m of target and surveyed within 1 m, whilst maintaining the cost, rapidity, safety and environmental benefits of a greenfield CT rig.


• Extend the reach of mineral exploration Coiled Tubing drilling to at least 1000m.

• Develop steering of the drill bit, while drilling hard rock with the possibility of drilling several geological targets from the same drill pad or the same hole.

• Deliver sample integrity comparable to diamond coring.
