Working Life

The work of a Geo-Driller involves extracting soil samples, installing monitoring equipment, undertaking in-situ testing, assessing and developing water supplies, facilitating the installation of ground support and preparing holes to be charged with explosives for blasting.

Soil and rock are extremely variable and competent drilling requires care, attention to detail and the ability to record accurately the variations encountered below ground either by sampling, written documentation or a combination of both.

Work will involve: 

• Moving drill rig to site – competent in transportation of heavy equipment Assessing ground conditions for set up of a rig
• Setting up a drill rig at predetermined locations – uneven ground, sloping ground, soft ground, under ground
• Safe and productive drilling in varied ground conditions – competent in the areas of health and safety and manual handling
• Sampling and recording (logging) the investigation/drilling findings accurately for use by designers – engineers, geologists, hydrogeologists
• Communicating drilling findings

Most commonly reported Work Tasks

• Operate controls to stabilise machines and to position and align drills.
• Start, stop, and control drilling speed of machines and insertion of casings into holes.
• Regulate air pressure, rotary speed, and downward pressure, according to the type of rock or concrete being drilled.
• Select and attach drill bits and drill rods, adding more rods as hole depths increase, and changing drill bits as needed.
• Drive or guide truck-mounted equipment into position, level and stabilise rigs, and extend telescoping derricks.
• Operate machines to flush earth cuttings or to blow dust from holes.
• Verify depths and alignments of boring positions.
• Perform routine maintenance and upgrade work on machines and equipment, such as replacing parts, building up drill bits, and lubricating machinery.
• Select the appropriate drill for the job, using knowledge of rock or soil conditions.
• Document geological formations encountered during work.

This occupation is typically suited for people with the following Career Interests:

 Realist

Realists are usually interested in 'things' - such as buildings, mechanics, equipment, tools, electronics etc. Their primary focus is dealing with these - as in building, fixing, operating or designing them. Involvement in these areas leads to high manual skills, or a fine aptitude for practical design - as found in the various forms of engineering.

Realists like to find practical solutions to problems using tools, technology and skilled work. Realists usually prefer to be active in their work environment, often do most of their work alone, and enjoy taking decisive action with a minimum amount of discussion and paperwork.

 Investigative

The Investigative person will usually find a particular area of science to be of interest. They are inclined toward intellectual and analytical activities and enjoy observation and theory. They may prefer thought to action, and enjoy the challenge of solving problems with sophiscticated technology. These types prefer mentally stimulating environments and often pay close attention to developments in their chosen field.

Pathways in learning & training to develop a career in Geo Drilling can be developed in stages.

Note: The following information relates to occupations that include: Laboratory technicians; Electrical and electronic technicians; Engineering technicians Quality assurance; technicians Planning, process and production; technicians Science, engineering and production technicians n.e.c.

This information has been derived from the Solas National Skills Bulletin (2023).

Employment levels fell between 2021 and 2022, by approximately 3,000 persons, but remained above 2017 levels, resulting in a positive, but below average, annual average growth rate for the five-year period. Employment for this occupation was primarily in industry (accounting for a 60% share of employment). Employment permits issued were across a variety of technician roles (e.g. process, manufacturing, laboratory). The Recruitment Agency Survey identified vacancies for maintenance technicians in manufacturing with electrical/mechanical skills as difficult-to-fill.

Employers (Skills for Growth) experienced difficulties in filling a range of engineering technician roles, including aircraft technicians and manufacturing technicians, particularly for those with digital skills and knowledge of procedures/processes. There was a 3% increase in the number of online job adverts in 2022, driven by increases in electrical/electronic technicians and, to a lesser extent, laboratory technicians.

New apprenticeship registrations for a number of industry related technicians (including lab analysts) have risen strongly since the first of these programmes were introduced in 2017; by 2022 there were 314 new registrations across a range of apprenticeships (lab analyst, manufacturing technology, OEM engineer etc.) up from approximately 100 in 2017. Although demand seems to be lessening for these roles, issues with attracting suitable candidates remain for maintenance and laboratory technicians in particular, at least in the short-term.
