Approximately 75% of the proven conventional oil reserves in the Middle East occur in carbonate reservoirs like Mauddud in North Kuwait. Today, this reservoir is the focus of aggressive development through drilling of horizontal wells.

Mauddud in North Kuwait is heterogeneous with varying rock and fluid properties between crest and periphery. A major challenge in its development is the presence of high permeability streaks that are random, inconsistent and unpredictable. Though typical of carbonates this causes early breakthrough into producers and cycling of injection water into patterns resulting in poor sweep efficiency and oil recovery. The reservoir is under active water flood for over 10 years.
