... Abstract In recent years, the application envelope for inflow control devices (ICDs) has significantly shifted toward harsher environments, for example, to high temperature changes for SAGD, high production pressure differentials in wells with high reservoir permeability contrast, and extreme...

... increases with time for a constant rate drawdown in the tested layer due to the increasing pressure differential across the compromised zonal isolation. The test duration is another important aspect which lets the cross-flow rate reach a critical value to be detected in the log-log plot of the pressure...

... Abstract Reservoir flow control is important for maximizing hydrocarbon production. Traditional in-flow control devices (ICDs) attempt to balance the completion pressure differential with the reservoir pressure differential so that even flow across production zones is maintained. This maximizes...
