.... The presence of flow barriers caused by these shales and variations in directional permeability across the reservoir strongly affect the drainage patterns and the sweep efficiency of water injection processes ( Awejori, 2010 ). Therefore, to accurately estimate the efficiency of a waterflooding process...

... with the sweep efficiency decreasing as M increases for a given volume of fluid injected. Furthermore, M affects the total stability of a displacement process with flow becoming unstable when M > 1.0 this unstable flow is called viscous fingering, a value of M > 1.0 is regarded as unfavourable mobility...

... factors at play in the performance of these reservoirs. The results were consistent and showed that globally recoveries above 70% are possible. It has also been further established that recovery factors are largely influenced by 4 efficiencies namely - microscopic sweep efficiency, macroscopic sweep...

... by a simple economic analysis. It was then recommended that additional water injectors be drilled in P-Upper North and Q-Lower to unlock an additional 8.4 MMSTB of reserves resulting from higher sweep efficiencies and better pressure maintenance. Artificial Intelligence subsea network waterflooding...

... as to improve sweep efficiency. In October 2011, Inj-03i and Inj-05i commenced water injection into the western region of X01 and X02 reservoirs respectively. By February 2013, reservoir pressure in the western area of X01 reservoir had risen to 1700 psi, from its pre-water injection value of 1000 psi...
