Modeling and Simulation of Micro/Nano-Scale Oil and Gas Migration in Tight Rocks and Shales
Description
With the rapid development in the technology of hydraulic fracturing and horizontal drilling, shale and tight reservoirs are gradually becoming the game changer in the energy industry. However, numerous challenges still need to be addressed in the effective recovery of oil and gas from tight and shale reservoirs. Especially, a micro/nano-scale pore space leads to a challenge in the modeling and simulation of oil and gas migration in tight rocks and shales; this is because many migration mechanisms (e.g. flow regime) have significantly changed at the micro/nano-scale compared with conventional reservoirs. Initiatives of modeling and simulation of micro/nano-scale oil and gas migration include but not limited to molecular dynamics, phase behavior, pore-scale modeling, transport process, and storage mechanism. Convincing modeling and simulation work on micro/nano-scale oil and gas migration should have a good validation against experimental observations.
This Special Issue aims to deepen the understanding of tight/shale oil and gas migration processes at the micro/nano-scale. We encourage submissions focusing on modeling and simulation studies that could address the challenges of oil and gas migration at the micro/nano-scale in tight rocks and shales. Both original research and review articles discussing the current state or the art are welcomed.
Potential topics include but are not limited to the following:
- Phase behavior modeling
- Pore-scale modeling
- Gas adsorption and desorption
- Molecular simulation for tight/shale oil and gas
- Wettability and capillary imbibition
- Oil and gas flow simulation considering multiple mechanisms
- Apparent permeability model for tight/shale rocks
