Waterflooding: A key Option for Stratified Oil Reservoirs in the Niger Delta

This research work looked at the applicability concept of waterflooding as a key option for enhanced recovery of oil from stratified reservoirs in the Niger Delta, South of Nigeria. Waterflooding is a secondary recovery technique that commences after a homogeneous or multi-layered (stratified) reservoir has reached its economic limit by every possible primary recovery drives (i.e. natural drive mechanisms). The research also covered for Niger Delta the sweep/displacement efficiency deliverability of multi-layered (stratified) reservoirs, reservoir permeability ordering, the effect of waterflooding rates, and effectiveness of waterflooding schemes for multi-layered oil reservoirs, fractional flow of water during waterflooding processes, and the frontal advancement of the water front along the reservoir bed at a given time (t) in days.
