Oil production currently has challenges such as excessive water production, which reduces the cumulative oil recovery, this occurs due to water coning in the reservoir which resulted to earlier water breakthrough in the wellbore. Various Down hole Flow control Devices (DFCs) including ICDs, AICDs, and AICVS are typically installed in the horizontal section of oil wells to mitigate the problem. The study of autonomous ICDs was done by comparing the long term flow performance of such devices against passive ICDs. The study was carried out with a reservoir model representing one horizontal well (X2) with three completion alternatives: open hole, ICD and AICDs which were perforating in numerical reservoir model, the model and completion was built and designed by (Petrel 2016) software; these cases were run in the Eclipse simulator and their results were compared with the open hole. The installation of DFCs (ICDs, and AICDs) in the horizontal well increased the oil recovery (RF) significantly, however the installation of Autonomous ICDs (AICDs) in the horizontal well perforating the oil reservoir increased more oil when compared against the passive ICDs, and this had been proved by the results of the reservoir model.
