Design and implementation target inefficient flood patterns to improve oil production by redirecting injection fluid to a tighter, unswept portion of the reservoir. Conformance treatments address high-permeability streaks known as thief zones by blocking these areas deep into the reservoir, thus forcing the injection fluid around the gel block into tighter, oil-saturated rock. This treatment results in the mobilization of bypassed oil to the offset production wells, often resulting in significantly increased reserve recovery.
Vertical Profile Modification:
Design and implementation target inefficient vertical injection profile. In cases where multiple zones are being flooded from a single injection well, the vertical profile will favor one or two intervals with 70% or greater volume of the total daily barrels injected, creating a significant inefficiency in the flood pattern. Vertical Profile Modification Treatments address injection profile inefficiencies by directing injection fluids more proportionally in situations where multiple zones are open, thus increasing oil production.
