A reservoir-scale numerical conceptual model was established according to the actual geological characteristics of a carbonate fractured-vuggy reservoir. Considering difference in density and viscosity fluids under reservoir conditions, CFD (computational fluid dynamic) porous medium applied simulate process nitrogen displacement after water flooding. The effects gas injection rate, mode, injec...

Several countries, including Canada, contain sizeable bitumen resources in highly fractured carbonate rocks. Any possible recovery of bitumen from these reservoirs will be highly dependent on proper understanding of the rock and fluid properties and how they vary in the reservoir. These carbonates are extremely heterogeneous, and as a result proper reservoir characterization is challenging. In ...

BACKGROUND The initial part of process development involves extensive screening programs to identify optimal biological systems and cultivation conditions. For a successful scale-up, the operation mode on screening and production scale must be as close as possible. To enable screening under fed-batch conditions, the membrane-based fed-batch shake flask was developed. It is a shake flask mounted...

Natural reservoirs exhibit high degree of spatial variability in their properties in multiple length scales. It has been established that such variability has a strong impact in determining fluid flow patterns in subsurface formations. Direct measurements of reservoir properties are only available at a small number of locations. Without an adequate description of the formation properties, such ...

• Molecular simulations reveal scaling law for local adsorption of methane in kerogen. Pores less than 1 nm have significant capacity, impacted by size and pressure. Porosity plays the key role inside New percolation model proposed to predict isotherms nano-porous media. Percolation only requires input kerogen atoms is scalable experiments. Developing unconventional shale gas resource has incre...

Microfluidic polymethylmethacrylate (PMMA) devices for study of particle transport in artificial porous media were designed and microfabricated using hot embossing with a brass mold insert containing a microchannel network with eight layers. After thermal bonding to enclose the microchannel network, a process protocol was applied to successfully remove bubbles in the PMMA device. Characterizati...

In this paper, the effect of consolidation soil structure on fractality fluid flow was evaluated. The equation fractal law in porous medium under two-phase, fully fluid-saturated determined. Given all simplifications, as well undoubted importance nature medium, which primarily determine possible processes both and based results studies, we can conclude that a homogeneous reservoir at given para...

The effects of an adsorbing phase on the injection of liquid and eventual production of vapor from a lowporosity, vapor dominated geothermal reservoir was studied. The magnitude of delay caused by adsorption, diffusion partitioning, preferential partitioning, and permeability variation were compared. Results were then compared to measured tracer production data at the Geysers to determine the m...
