WIREBmr™ is a downhole geophysics tool that measures the water in a subsurface environment safely, efficiently and accurately. The hardware is specifically tuned to sense fluids within the pore network of the formation, delivering precise determination of the rock's total porosity, mobile fluid and bound fluid and enabling calculation of hydraulic conductivity. WIREBmr™ characterises an entire borehole in a single run without an active radiation source, offering significant time and cost savings over traditional methods.
