Tittel

Cross-scale modeling of CO2/hydrocarbon conversion in hydrofractured shale

Vitenskapelig sammendrag

In shale gas systems, natural gas is produced directly from organic-rich shales through drilling and hydrofracturing. The methane is adsorbed at interfaces, absorbed by the kerogen shale, and contained as free gas and/or gas dissolved in water in pore volumes and fracture apertures. Interestingly, the affinity for carbon dioxide is stronger than the affinity for methane, and carbon dioxide may therefore be used to enhance gas production.

 

This project involves fundamental research on the molecular physisorption/chemisorption and the meso-scale gas transport processes in nanostructured shales. The project strategy is to combine our knowledge from condensed matter physics, forces theories for molecules, and continuous transport models to explore details in the physical properties and processes of carbon dioxide and methane in water-rich shale nanostructures. This will be realized by four scientifically intertwined work plans. WP1: Analyses of crystal structure and surface reconstruction by means of density functionals. WP2: Atomistic simulation of surface of adsorption and desorption. WP3: Green functions modeling of physisorption and chemisorption to analyze surface-gas-water interactions, molecule formation, and stiction.WP4: Explore the surface-near transport and deformation in shale systems with a direct simulation Monte Carlo approach.

 

 

The project will be carried out and completed at the Department of Physics at University of Oslo by the research teams at Geophysics, linked to Center for the Physics of Geological Processes, and at Structure Physics, linked to the Centre for Materials Science and Nanotechnology. Strong international collaboration will serve for networking, exchange of knowledge, and scientific visibility. Long-term international research visits by the PhD student and the postdoctor will strengthen these contacts.
