Title
(EN) TOTAL STORAGE CAPACITY AND TOTAL POROSITY OF POROUS MEDIA
(FR) CAPACITÉ DE STOCKAGE TOTALE ET POROSITÉ TOTALE DE SUPPORTS POREUX
Abstract
(EN) Evaluating a gas reservoir or the capacity of a reservoir to store C02, requires and understanding of the total porosity and the gas per unit volume storage capability of the porous material comprising the reservoir. In general, storage capacity is a function of the porous material properties, the reservoir pore pressure, and temperature. Total porosity and storage capability are difficult to characterize when multiple storage mechanisms are present. The current invention provides an apparatus which uses a multi-stage filling process combined with NMR to determine the total storage capacity and total porosity as a function of pressure and temperature. Advantageously, the present invention provides for performance of these measurements under in-situ subsurface conditions.
(FR) L'invention concerne l'évaluation d'un réservoir de gaz ou la capacité d'un réservoir à stocker du CO2, et nécessite la compréhension de la porosité totale et de la capacité de stockage de gaz par unité de volume du matériau poreux constituant le réservoir. De manière générale, la capacité de stockage est fonction des propriétés du matériau poreux, de la pression dans les pores du réservoir et de la température. La porosité totale et la capacité de stockage sont difficiles à caractériser lorsque de multiples mécanismes de stockage sont présents. La présente invention fournit un appareil qui utilise un processus de remplissage par stades multiples combiné à une technique RMN pour déterminer la capacité de stockage totale et la porosité totale en fonction de la pression et de la température. Avantageusement, la présente invention permet de réaliser ces mesures in situ en sous-sol.
