Legion Drilling recently completed a mineral exploration drilling program with a sonic rig in unconsolidated formations for Nickel Laterite.

One of the highlights of 2017 was being involved in the Sydney Metro Geotechnical investigation in Sydney Harbour. Legion Drilling was presented with an opportunity to use one of our Sonic drill rigs from an overwater in close proximity to the Harbour Bridge.

".....look for a cost-effective method for characterising shallow groundwater resources in remote Northern Australia"

Legion Drilling Services Australia was awarded a public tender by Hunter Water to manage and undertake the drilling and installation of 15 municipal water production bores within the existing use regional aquifer.

Using tracers to Investigate aquifer recharge. A wide a range of tools wre employed to gather data including monitoring wells, the Hydraulic Profiling Tool (HPT), Geoprobe push tube soil sampling and the SP16 groundwater sampler in this investigation.

Sonic Drilling is taking off in Australia and is quickly becoming the preferred tool in both Environmental and Geotechnical site investigations. After a couple of years of use this is the lowdown on where we see the value.

The HPT provides a continuous hydrostratigraphic log of the subsurface that provides relative hydraulic conductivity of the formation.  Soil lithology is also mapped along the vertical profile of the subsurface. Identify pathways and calculate permeability and static water levels in real time...

Run on a Geoprobe drilling rig, the UVOST systems makes for a much more productive day in the field. Real time delineation LNAPL plumes can be conducted with speed and with complete confidence. There is a greatly reduced requirement for soil sampling, laboratory analysisand groundwater wells.
