Borehole Flowmeters
There are several types of flowmeter probes available to identify, measure and quantify the flow of groundwater in a borehole. Such data will provide important insights into the local hydrogeology which includes: • Source of groundwater flow in a borehole. • “Thief...
Porosity Measurement
A simple definition of porosity or the amount of pore space is the volume of space within a rock which can be occupied by gas (air) or a fluid (water, oil). Measuring the porosity of a rock will give an indication of its storage potential for groundwater, oil or gas....
Geological versus geophysical borehole sampling
The geologist is interested in collating and understanding all data which originates from a borehole. The data may be in the following forms: Geological samples Cylindrical core samples from an interval of the borehole or the whole borehole. Chip samples from the...
Could borehole geophysical logging help unlock the mystery of Clovelly Park’s pollution plume?
This is a hot topic in Adelaide at the moment where several polluted sites in and around Clovelly Park are under investigation. Most are associated with previous heavy manufacturing industries which have since moved on. However, the pollution plume is now affecting...
