Among the recent deents to improve oil and gas recovery, water injection called waterflooding could be promising. The objective of this work is to ascertain the optimal water injection arrangement between vertical and horizontal waterflooding using ECLIPSE Reservoir simulation software. Within this work, analyses of oil production rate, water cut, reservoir pressure drop, accumulated oil production and recovery factor were made between horizontal and vertical waterflooding in a homogeneous reservoir. Result shows that horizontal waterflooding could be effective if water breakthrough is delayed. The increase in oil recovery achieved through this method varied between 6% and 36% while the delay in breakthrough varied between 459 days and 1362 days. This work also predicts production performance for ten years which would be useful for dynamic optimization of waterflooding. However, reservoir heterogeneity would introduce geological uncertainty, which could bring mismatch between the simulated case and a real case.
