Title: Method of upscaling permeability for unstructured grids
Inventor: KHAN SAMEER A
IPC: G01V1/30
Filed: 2000-06-21
Granted: 2010-08-03
Abstract: A method is provided for scaling up permeabilities associated with a fine-scale grid of cells representative of a porous medium (fig.1) to permeabilities associated with an unstructured coarse-scale grid of cells representative of the porous medium (fig.3). An areally unstructured, Voronoi, computational grid is generated using the coarse-scale grid as the genesis of the computational grid. The computational grid is then populated with permeabilities associated with the fine-scale grid. Flow equations are developed for the computational grid, the flow equations are solved, and inter-node fluxes and pressure gradients are then computed for the computational grid. These inter-node fluxes and pressure gradients are used to calculate inter-node average fluxes and average pressure gradients associated with the coarse-scale grid. The inter-node average fluxes and average pressure gradients associated with the coarse grid are then used to calculate upscaled permeabilities associated with the coarse-scale grid.

Abstract: L'invention concerne un système de gestion de présence, au sein duquel des connexions entre les parties de surveillance et les parties surveillées sont gérées dans un réseau de communications à accès multiples. Lorsque le système de gestion de présence reçoit une demande de contact de la part de la partie de surveillance, il détermine si la partie surveillée demandée est disponible pour une mise en contact. Ledit système fournit alors des informations concernant ce point à la partie de surveillance qui a effectué la demande. Le système de gestion de présence choisit le meilleur mode de communication (par exemple courrier électronique ou télécopie) en tenant compte des préférences des parties surveillées et des détails concernant les installations disponibles pour la partie de surveillance. Si le système de gestion de présence informe la partie de surveillance que la partie surveillée n'est pas disponible, la partie de surveillance peut installer un appareil de surveillance. Lorsque le système de gestion de présence détermine si la partie surveillée demandée est disponible à une mise en contact, il utilise des informations stockées concernant la partie surveillée, des informations concernant la connexion requise (par exemple la taille et le type) et également des règles. En outre, des informations concernant des événements provenant du réseau à accès multiples, par exemple l'emplacement géographique des téléphones mobiles de la partie surveillée, sont utilisées. De manière avantageuse, des parties surveillées ou des parties de surveillance sont des services. Par exemple, une partie de surveillance constitue un service d'appels de conférence qui surveille des parties surveillées et établit un appel de conférence lorsque les parties surveillées sont disponibles. Une partie surveillée peut également constituer un service, tel qu'une agence de billets. Des parties de surveillance peuvent installer des appareils de surveillance au moyen du système de gestion de présence à prévenir lorsque de nouveaux billets sont disponibles à l'agence.
