Drilling techniques in industry have not changed for decades. Oil rigs are built in he same old way. Now something has come along that will improve drilling enormously. The Deep Exploration Technologies Cooperative Research Centre based in Adelaide has announced a new type of drill. It is constructed with coiled tubing.
Costs will fall dramatically as drilling is faster. Australia's mines are mostly over 30 years old. New mines have to be established. We can only rely on the old mines for another 20 years.
No longer is it necessary to keep stopping to add a new drilling section. The new drill is a continuous coil of tubing. Being smaller and lighter transportation is easy. The motor is at the bottom of the shaft, not at the top. The tubing no longer twists during drilling. Any twisting will occur in the other direction as the motor pulls the tubing around.
Less drilling power is needed as the tubing is being pulled around in already drilled space. A lot of torque was lost with the old system as the engine had to force the whole length of the drill around. Drilling will continue with fewer drill breakages. Thus, downtime will be reduced.
