Employment Opportunities for a Driller's Assistant
Drillers’ assistants are employed by drilling contractors, mining companies, oil companies, consultants and farmers. They work at construction sites, mines, and oil and gas exploration and production facilities situated offshore and onshore. Demand for drillers’ assistants varies greatly with commodity prices, general economic conditions and government policies in relation to mining, groundwater regulations and infrastructure projects. Crossover from one sector of the drilling industry to another often occurs when a sector is quiet. Many drilling contractors operate in several sectors. Opportunities exist for those with sound practical experience to move into management or supervisory roles.
The major sectors in the drilling industry are:
- Blasthole drilling to place explosives for the removal of rock and ore in quarries and mines, as well as the construction of roadworks, dam sites and other capital works.
- Mineral exploration and investigation drilling for suspected or known mineral deposits (this is carried out both in Australia and by Australian companies overseas).
- Oil and gas drilling (this is carried out offshore and onshore by contract companies that are mainly employed by oil companies).
- Site investigation/geotechnical drilling to determine the characteristics of soil and rock on construction sites.
- Foundation/construction drilling on construction sites, usually in towns and cities, as a part of the building or construction process.
- Water well drilling for stock and domestic or commercial bores (this is mainly carried out by private contractors based in rural areas).
A driller runs a team of drillers' assistants performing the above tasks. Drillers may specialise in diamond core drilling, rotary/percussion drilling, coal seam drilling or water well drilling.
