Focussed on the distribution and movement of groundwater in the subsurface, Hydro-Log solutions employ wireline logging technologies to rapidly acquire in-situ, high-resolution data sets that when correctly processed and interpreted, yield high-confidence hydrological properties including:

• Aquifer location

• Fluid flow under static or induced conditions

• In-situ porosity characterization

• Hydraulic conductivity

• Clay mapping and typing

• Wet & dry bulk densities

Borehole Magnetic Resonance

​

Digital Surveying is the distributor for NMR Services Australia's BMR, the world's most advanced magnetic resonance technology developed for slimline logging applications. BMR uses an advanced and completely safe (non-ionising) magnetic resonance technique to directly measure the presence of hydrogen found in water, contained within the rock structure, as well as to characterize the storage sites. BMR provides a lithology-independent measurement of porosity which can be used in a multitude of different industries where the water content in the rock matrix plays a critical role.

Applications of BMR include:

• Hydrogeology - mapping specific retention, yield & hydraulic conductivity

• In-situ adsorbed gas mapping in coal-(methane) & helium deposits.

• Brine / solution mining
