Title (EN) SYSTEMS AND METHODS FOR DETECTING LIVING ORGANISMS IN SEDIMENTS AND ROCKS
(FR) SYSTEMES ET PROCEDES DE DETECTION D'ORGANISMES VIVANTS DANS DES SEDIMENTS ET DES ROCHES
Abstract:
(EN) The embodiments are directed to systems and methods for determining in-situ micro­organisms in a solid matrix including sediments and rocks. The methods include collecting data such as, effective measured complex dielectric constant, propagation and attenuation time of an electromagnetic wave and porosity, using a multi-frequency impedance spectrometer, an electromagnetic propagation device and a density device. The method further includes calculating and comparing an effective complex dielectric constant with the measured complex dielectric constant and determining a cell concentration of the micro-organisms.
(FR) De façon générale, l'invention concerne des systèmes et des procédés permettant de déterminer la présence in situ de micro-organimses dans une matrice solide formée notamment par des sédiments ou des roches. Les procédés consistent à recueillir des données - constante diélectrique complexe effectivement mesurée, temps de propagation et d'atténuation d'une onde électromagnétique et porosité - au moyen d'un spectromètre d'impédance multi-fréquence, d'un dispositif de propagation électro-magnétique et d'un densimètre. Le procédé consiste en outre à calculer une constante diélectrique effective complexe et à la comparer à la constante diélectrique complexe mesurée, et à déterminer la concentration cellulaire des micro-organismes.
