Abstract: Abstract The subject reservoir is a geologically complex Lower Cretaceous carbonate system, which is on water flood recovery scheme. Due to extreme diagenesis and associated geologic heterogeneity (which include faults, fractures, burrows and algal floatstone), water breakthrough occurred early and oil recovery is low due to water channeling and by-pass of huge volumes of un-swept hydrocarbon. The low recovery performance is compounded by the relative thinness of the reservoir as well as unfavor…
