Abstract
This invention relates generally to methods for monitoring directional flood front movement during oil recovery and more specifically to methods for monitoring flood front movement of flooding agent injected into subsurface formations. The method comprises detecting physical properties of subsurface formation and injection of a flooding agent into said formation through at least one injection well thus forcing reservoir oil movement toward at least one production well. The flooding agent is a highly dispersed gas-liquid mixture having size of gas bubbles not exceeding an average diameter of the pores of said oil-bearing reservoir. The method further comprises detecting the same physical properties of the formation at the same area after flooding and monitoring the flood front profile by registrating changes in the physical properties of the formation caused by the arrival of said flood front.
