<p>The present invention relates to the process and devices for assessing the permeability of a rock medium (1) containing a fluid (2) in its interstices (3). The device and the process according to the invention are characterised essentially in that means (10) allow a given magnetic field to be applied to the interstitial fluid (2) located in the rock medium (1), means (11) allow the variation in pressure of the interstitial fluid (2) resulting from the application of the magnetic field to be measured, and means (12) allow the permeability of the rock medium to be determined as a function of the value of the variation in pressure of the interstitial fluid.</p> |
