Utilize high injection/ low production well pattern and WAG injection mode to change strong/weak streamline distribution
(After gas is injected to higher part of the reservoir, it gathers at Ⅱ type of channel. With the pressure increase weak streamline
will open ). Thus residual oil between wells is driven out and oil recovery is enhanced.
