Pattern Effect for Oil Reservoir Waterflooding Using Smart Well

Waterflooding is a primary enhanced oil recovery involving the injection of water into an oil-gas rich reservoir to increase production capacity. Waterflooding is one of the most used enhanced oil recovery technique due to the fact that water is readily available and cheap to maintain. However, with the efficacy of implementing waterflooding recovery technique, only about 35% of the original oil in place (OOIP) is produced. This research is aimed at investigating the effect of placement pattern for non-conventional or smart wells. Comparison is made with respect to previous study where which conventional wells are used. Three cases were investigated on the basis of recovery and complexities in field development. It was observed from this study that conventional wells are not a good candidate for oil well productivity as compared to non-conventional (smart) wells. Conventional wells also pose a limitation to the economic value of the reservoir due to poor well contact. The first, second and third case recorded an NPV of $7.5 trillion, $7.59 trillion and $8.81 trillion respectively. Implementing smart wells also curtailed an early water breakthrough by about 70%. An average gain of 99.7% was also recorded for all cases as against previous study. These results indicated the efficiency of implementing smart wells over conventional wells.
