Micro/nano (small) scale transport phenomena such as flow of gas, oil or water in very tight underground rocks abound in nature, technology, and science. Small scale fluid transport mechanisms refer to the involvement of micro/nano geometries in fluid flows or flows driven by forces arising from the presence of micro/nano scale bodies. Examples of micro/nano transport phenomena include enhanced oil production, chemically based in-situ remediation of soil and water, geological storage of carbon dioxide, gas production from very tight reservoirs, migration of micro-organisms, bio-analytical processes in nanotechnology and micro-chemical reactors, and others. ****This proposal supports research on gas transport mechanisms in shale gas reservoirs, and the characterization of related energy resources. Gas producing shales are fine-grained sedimentary rocks with a high organic content that can be rich sources of petroleum and natural gas. Because of the clay content, desorption and gas transport occurs in nano-pores. As a part of this research program, we will work to understand the gas transport mechanisms in shale and the effect of the distribution of organic content, known as kerogen, on these mechanisms. Furthermore, we will research how easily gases can pass through shale formations with measures of property known as permeability. This will involve investigating the effects of gas molecule sizes and pore surfaces on shale permeability. Within this program, we will perform experiments for the discovery of new phenomena, develop a mathematical model of nano scale flows and simulate these flows using high performance computers. This highly integrated methodology is believed necessary to discover the physical mechanisms that control nano scale flows and the knowledge gained can be valuable to other fields. This program also provides an excellent environment to train highly qualified students at the graduate and postdoctoral levels.****

微/纳米（小）尺度传输现象，如气体，石油或水在非常紧密的地下岩石中的流动，在自然界，技术和科学中比比皆是。小尺度流体传输机制是指在流体流动或由微/纳米尺度主体的存在引起的力驱动的流动中涉及微/纳米几何形状。微/纳米迁移现象的例子包括提高石油产量、土壤和水的化学原位修复、二氧化碳的地质储存、从非常致密的储层中生产气体、微生物的迁移、纳米技术和微化学反应器中的生物分析过程等。* 该提案支持对页岩气储层中的气体输运机制以及相关能源资源的表征进行研究。产气页岩是具有高有机含量的细粒沉积岩，其可以是石油和天然气的丰富来源。由于粘土含量，解吸和气体传输发生在纳米孔隙中。作为这项研究计划的一部分，我们将努力了解页岩中的气体传输机制以及有机含量（称为干酪根）分布对这些机制的影响。此外，我们还将研究气体如何容易地通过页岩地层，并测量其渗透率。这将涉及研究气体分子大小和孔隙表面对页岩渗透率的影响。在这个项目中，我们将进行实验，发现新的现象，开发纳米尺度流动的数学模型，并使用高性能计算机模拟这些流动。这种高度集成的方法被认为是发现控制纳米尺度流动的物理机制所必需的，所获得的知识对其他领域也有价值。该计划还提供了一个良好的环境，培养高素质的学生在研究生和博士后水平。
