Title (EN) SYSTEMS AND METHODS FOR MEASURING RELATIVE PERMEABILITY FROM UNSTEADY STATE SATURATION PROFILES
(FR) SYSTÈMES ET PROCÉDÉS DE MESURE DE LA PERMÉABILITÉ RELATIVE DE PROFILS DE SATURATION D'ÉTAT INSTABLE
Abstract:
(EN) An example system for obtaining relative permeability from unsteady state saturation profiles is described herein. The system can include a pressure source configured to inject a first fluid into a core, and a nondestructive test (NDT) device configured to measure a saturation profile of a second fluid along the core. The saturation profile of the second fluid can be measured at each of a plurality of times. The system can also include a processor and a memory in operative communication with the processor. The processor can be configured to estimate one or more parameters related to conditions of the core directly from the respective saturation profiles, and calculate the relative permeability using the one or more parameters.
(FR) Un exemple de l'invention concerne un système destiné à obtenir une perméabilité relative à partir de profils de saturation d'état instable. Le système peut comprendre une source de pression configurée pour injecter un premier fluide dans un noyau et un dispositif de test non destructif (NDT) configuré pour mesurer un profil de saturation d'un deuxième fluide le long du noyau. Le profil de saturation du deuxième fluide peut être mesuré à chacun d'une pluralité d'instants. Le système peut également comprendre un processeur et une mémoire en communication fonctionnelle avec le processeur. Le processeur peut être configuré pour estimer un ou plusieurs paramètres en rapport avec des conditions du noyau directement à partir des profils de saturation respectifs, et pour calculer la perméabilité relative en utilisant le ou les plusieurs paramètres.
