Description
Recovery from shale and tight oil reservoirs remains limited, with recovery factors often below 10% of the original oil in place despite horizontal drilling and hydraulic fracturing. Traditional reservoir models fail to capture the physics of nanometer-scale pores, where confinement, adsorption, and molecular diffusion dominate. This presentation examines how confined thermodynamics reshapes phase behavior and miscibility, supported by experimental core-flooding and CO₂ Huff-n-Puff studies with CT scanning. Results show diffusion and oil swelling as critical recovery mechanisms, and predictive models that couple thermodynamics with transport phenomena offer more realistic production forecasts. Beyond improving unconventional oil recovery, this work highlights broader implications for subsurface processes, including CO₂ storage and hydrogen containment.
