A conceptual and mathematical framework proposing that subsurface fluid systems can be interpreted through a pressure–resistance state parameter (Λ), separating confined/stable, critical/metastable, and open/active regimes. The framework integrates pressure buildup, geological resistance, migration, capillary behavior, thermal evolution, fluid-rock interaction, sealing, and dynamic accumulation into a unified organizational model. Rather than replacing classical transport physics, the framework extends existing interpretations by focusing on regime behavior in deep, confined, overpressured, and structurally complex systems. Reservoirs are interpreted as metastable organized states emerging from coupled pressure, resistance, thermal, and geochemical processes. The work also outlines possible future extensions toward broader subsurface carbon-system organization, including solid carbon systems such as coal formation.
