Energy is becoming a critical issue for the economic prosperity of the country. Efficient strategies need to be developed for extracting every last bit of oil residing within the pores of reservoirs, which are typically 2 - 5 µm in size. Such strategies can only evolve through in-depth understanding of the fluid mechanics occurring in the pore-scale. A typical oil field (or reservoir) extends a few hundred meters below the earth's surface and is porous in nature containing oil and water phases in an interconnected three-dimensional network of pores. The proposed research program aims to address this energy issue by taking a close look at the phenomena which are occurring in the micro-scale. The research program has both modeling and experimental components. The state-of-art modeling approaches in two-phase flow, like Lattice Boltzmann and Pore-Network, will be used to understand the dynamics of the oil and water phases residing in the pore space of the reservoir. Experimental study involves the use of latest fabrication and characterization techniques in microfluidics and its novel application in the field of energy. Apart from addressing fundamental physical processes occurring in micro-scale, the outcomes of this research program will be useful for engineers working in the oil and gas sectors, particularly those involved in enhanced oil recovery processes like Steam Assisted Gravity Drainage (SAGD) used in the Province of Alberta.

能源正成为这个国家经济繁荣的一个关键问题。需要开发有效的策略来提取储层孔隙中的每一滴石油，这些孔隙通常为2 - 5 μ m。这种策略只能通过深入了解孔隙尺度上的流体力学来发展。一个典型的油田（或油藏）延伸到地球表面以下几百米，本质上是多孔的，在一个相互连接的三维孔隙网络中含有油和水相。拟议的研究计划旨在通过仔细观察微观尺度上发生的现象来解决这一能源问题。该研究方案包括建模和实验两部分。最先进的两相流建模方法，如Lattice Boltzmann和pore - network，将用于了解储层孔隙空间中油和水相的动力学。实验研究涉及微流体的最新制造和表征技术的应用及其在能源领域的新应用。除了解决微观尺度上发生的基本物理过程外，该研究项目的成果将对石油和天然气行业的工程师有用，特别是那些参与提高石油采收率过程的工程师，如阿尔伯塔省使用的蒸汽辅助重力排水（SAGD）。
