The energy and environmental sectors require to control the behaviour of fluids in the sub-surface. For example, the production of hydrocarbons from unconventional reservoirs depends on enhancing the fluid transport through pore networks characterised by size in the nm range, while storing CO2 requires identifying strategies for immobilizing this volatile gas for long periods of time. It is now accepted that the fluid behaviour in nano-pores differs substantially from that observed in the bulk phase. The general aim of this project is to achieve fundamental knowledge that could help reduce the long-term environmental impact of the energy sector. The project will make extensive use of molecular simulations, which will be validated against detailed experimental characterisation data.The specific aim of the project is to quantify how fluid properties such as density, transport, wettability, change when temperature, pressure, and fluid composition (in particular salinity) change. Of particular interest is the fluid behaviour when confined in nano-pores present in minerals (carbonates, clay, sandstone) commonly found in reservoirs to be used for CO2 storage.The applications that will benefit from this project include the energy sector in general, the environmental sector, and the combination of the two (achieving enhanced oil recovery via carbon sequestration). The fundamental understanding of the behaviour of confined fluids is also relevant for the specialty chemicals sector, as well as for developing catalysts.

能量和环境部门需要控制子表面中流体的行为。例如，来自非常规储层的碳氢化合物的产生取决于增强通过NM范围内大小为特征的孔网络的流体传输，而储存CO2则需要确定长时间将这种挥发性气体固定的策略。现在可以接受的是，纳米pores中的流体行为与在大量相中观察到的液体不同。该项目的总体目的是获得基本知识，以帮助减少能源部门的长期环境影响。该项目将广泛使用分子模拟，该模拟将根据详细的实验表征数据进行验证。该项目的具体目的是量化诸如密度，运输，润湿性，润湿性，变化时的流体特性时如何变化（尤其是盐度）变化。特别令人感兴趣的是，将矿物质（碳酸盐，粘土，粘土，砂岩）限制在储层中通常用于二氧化碳存储中的纳米倍数（碳酸盐，粘土，砂岩）中。将从该项目中受益的应用包括一般能源部门，包括一般环境部门，环境部门，两者的组合以及通过碳纤维造型增强了油的结合）。对限制液体行为的基本理解也与特种化学品和开发催化剂有关。
