This dissertation investigates the challenge of modeling fluid flow in porous media at scales relevant to reservoir engineering, moving beyond pore-level and macro-scale observations. The author addresses the impracticality of simulating flow at extremely fine scales for large-scale reservoir modeling. The work focuses on a tracer perspective to bridge the gap between detailed micro-scale phenomena and macroscopic flow behavior, aiming to develop effective upscaling techniques.

This work is presented as a Ph.D. dissertation, indicating a specialized academic audience. The focus on tracer perspectives suggests a detailed, technical approach to a complex problem in fluid dynamics and reservoir engineering. The research likely contributes to the ongoing effort to create more accurate and efficient models for subsurface fluid flow.
