Standard Measurements

NER uses unique measurement techniques to measure fluid permeability at in situ conditions. The method involves controlling a complex transient in pore pressure and monitoring the response.

Measurements of compressional and shear wave velocities are performed as a function of stress, pore fluid pressure, and temperature.  These measurements help in understanding the elastic properties of rocks.

Resistivity is measured as a function of frequency, stress, and temperature using two and four electrode techniques. NER’s ZMeter impedance analysis is used for true four electrode measurements.
