The aim of this study is to provide reservoir geologists and engineers with a strategy for optimizing the development, prolong field life and maximize recovery of bottom water driven gas condensate reservoirs. The approach focused on the review of the simulated results of various constructed radial numerical models from different producing gas and oil reservoirs in various fields. Technical papers and journals concerning hydrocarbon recovery and production were also reviewed. In this study, all factors that have potential impact on gas and oil ultimate recoveries such as gas production rate, completion length, aquifer size, horizontal permeability and permeability anisotropy were thoroughly studied and reviewed. Technological efforts to outwit challenges facing bottom water driven gas reservoirs such as water coning were also reviewed. Results showed that, low gas production rate is more preferred in order to prolong field production life, minimize water production and water breakthrough time in gas condensate reservoirs. The effect of aquifer size in gas recovery is not very much pronounced though the gas recovery increase with an increase in aquifer size up to aquifer size (M)=10 and then starts to decrease and for maximum gas recovery, the gas zone has to be totally perforated.
