Drilling Methods

Hinterland Drilling has extensive experience in environmental drilling services in a wide range of projects. We pride ourselves in our ability to conduct environmental drilling projects in difficult terrain, tight access and over water environments.

Hinterland Drilling have been involved in a number of environmental drilling projects:


  • ​Port of Brisbane - New cruise ship terminal
  • Port of Brisbane - Extensions
  • Port of Brisbane - Caltex refinery for pipeline under the Brisbane river to Brisbane Airport
  • Red Mud Dam


Environmental drilling is a drilling service performed when soil or groundwater samples are required in order to assess an area for contamination, or when groundwater monitoring wells or remediation wells are required for the treatment of groundwater.

Environmental drilling can include a number of drilling and probing techniques, including water bore drilling, hollow-stem auger drilling, and direct-push or probe sampling.

  • Water bore drilling is a rotary drilling system that is used to drill overburden sands, earths, gravels, cobbles, and rock formations to depth. These holes also allow the installation of monitoring instruments and testing equipment.
  • Hollow-stem auger drilling is a method that uses flight-style augers with hollow centres to drill soils to depth.  Soil samples are obtained by periodically driving hollow spoons down the inside of the hollow augers ahead of the cutting bit.
  • Direct-push, or soil probing, is a basic sampling method whereby a hollow sample tube is driven by either high pressure pushes or a high-speed hammer.

Why do we do environmental drilling?

What is environmental drilling?

We perform environmental drilling drilling for several reasons, ranging from ground water contamination monitoring, sampling ground water, removing waste and stabilising boreholes. The list of applications of environmental drilling includes:
  • Installing monitoring wells to measure the quality of ground water in situations where contamination is suspected or known
  • Installing recovery wells to pump and treat contaminated water
  • Collecting water, soil and gas samples for analysis
  • Installing monitoring wells to abstain if contaminated water from holding tailing dams is seeping through dam earth walls and contaminating water courses
  • Stabilising borehole areas
  • Removing waste
  • Multiport well installation to sample ground water at closely spaced intervals for investigations and remediation systems
  • Decommisioning of wells
