Miscible displacement procedure using a water bank
A method for recovering oil from a subterranean reservoir penetrated by a plurality of wells comprises the steps of: forming in the reservoir a continuous bank of water in spaced relationship about a central well by injecting water into the reservoir through a plurality of surrounding wells; producing oil from the reservoir through wells other than the wells being used for injecting the bank of water; injecting a miscible displacement fluid through the central well into the reservoir behind the bank of water; and driving the miscible displacement fluid radially outwardly through the reservoir from the central well and producing oil from the wells in the reservoir surrounding the bank of water.
