Накратко на български

Свойствата на шистовите скали и начинът, по който газовете се абсорбират в техните органични и минерални пори, се анализират чрез адсорбция на пари. Това помага за създаването на по-точни модели за транспорт на течности и по-безопасни технологии за добив на газ.

Advanced Characterization of Organic-rich Shales using Vapour Adsorption

This project is to advance the understanding of material properties of shales and the gases adsorption behaviour on shales. Material properties of shale, such as pore structure and surface property, are still under investigation because of the complex nature of shale. Shale contains a large amount of clay minerals, a small portion of organic matter, and other minerals like quartz and pyrite. Taking into account chemical/wetting differences of organic matter and minerals, pores in shale can be classified into hydrophobic organic pores and hydrophilic mineral pores. Unfortunately, surface chemistry differences at the nanoscale level within these pores are rarely considered due to the limitation of the instruments, and this has resulted in a knowledge gap in understanding surface chemistry/wetting properties in shales. The poor understanding of the shale material properties makes it impossible to develop a realistic fluid transport model for shale that considers surface chemistry properties. This severely impedes the development of next generation, safe and environmental friendly shale gas recovery technology. The outputs of this project discloses the material properties of shales at different dimensions and scales, which lays the foundation for improving current fluid transport models in shales by considering surface chemistry properties and developing the next generation of environmentally-friendly shale gas recovery technology through non-aqueous fluid injection and heat stimulation in order to serve shale gas development in the EU, U.S. and China. The overall aim of this project is to bring together a talented early career researcher with a background in unconventional gas engineering and gas adsorption science from the U.S., with a research group with expertise in material science and geoenergy from the UK. The main objectives of this project is to conduct an integrated material characterization of organic rich rocks (shales and coals), advance the understanding of gases adsorption behaviour on shales using modelling approach, and understanding the interactions between methane (adsorbed phase and gaseous phase) and water interaction within pore spaces.

Цел на проекта

The overarching goal of this proposal is to develop a novel experimental framework for quantifying the total specific surface area of organic matter and the wettability of pores in shales, and interpreting the displacement mechanism between gas and water by using a selective adsorption approach coupled with independent verified electron microscope measurements. The overarching goal of the project will be achieved through the following scientific objectives. First, a 3D structural model of the hydrophobic and hydrophilic site distribution in shales at around 50 nm resolution by combining FIB-SEM and high resolution TEM will be developed. This will provide an independent verification for later site-selective adsorption studies. Second, a vapour adsorption method by researching and verifying the most suitable probing vapours and the most reliable measuring approach will be developed. This will create a novel experimental framework for quantifying the total specific surface area of organic matter and the wettability of pores in shales, which will be verified by a previously-built 3D structural model. Last, the displacement mechanism between water and gas will be disclosed by determining the influence of hydrophobic and hydrophilic sites in shales using sequential adsorption and in situ NMR. This will be the essential theoretical part of the work for developing next generation enhanced gas recovery techniques through non-aqueous fluid injection and heat stimulation. The outputs of this project will disclose the chemical/wetting nature of pore systems in shales, which will be essential for improving current fluid transport models in shales by considering surface chemistry properties and developing the next generation of environmentally-friendly shale gas recovery technology through non-aqueous fluid injection and heat stimulation in order to serve shale gas development in the EU, U.S. and China.
