文摘
- •
Long permeability stabilization periods during corefloods with alternate flow rates.
- •
We attribute the long stabilization periods to slow drift of detached particles.
- •
The mathematical model for slow fines drift is developed; the exact solution is derived.
- •
Good agreement between laboratory data and analytical modelling.
- •
Maximum retention concentration is defined for mono-layer of size-distributed fines.
