recommendations! Published in 2024 at "Hydrogeology Journal"

DOI: 10.1007/s10040-024-02823-w

Abstract: The transition from Darcy to non-Darcy flow regimes was investigated using column experiments. This revealed key relationships between sediment characteristics and critical thresholds for the onset of the non-Darcy flow regime, as well as inertial… read more here.

DOI: 10.1016/j.petrol.2018.09.066

Abstract: Abstract Non-Darcy flows associated with high Reynolds numbers often occur in the near-wellbore regions of gas reservoirs or hydraulic fractures and thus should not be ignored. However, investigating non-Darcy flow in these porous rocks through… read more here.
