The development strategy of gas reservoir supported by an active bottom-water aquifer is essential and requires complete attention. Water inflow may cease production of gas wells, leaving a significant amount of gas in the reservoir. One of the most promising technique to enhance gas recovery is the co-production technique. This technique includes dual completion with an isolating packer at the bottom completion. The increased recovery is attributed to a reservoir response much similar to a depletion-drive since reservoir pressure is reduced due to water production, therefore more gas is produced by gas expansion. <br /> <br /> This paper attempts to describe and evaluate potential of associated production technology. Simulation studies were conducted, utilizing numerical simulator to develop the model and investigate recovery optimization by co-production. Sensitivity analyses are carried on define optimum rate for both completions and also the schedule of co-production. It is determined that the water production rate needed to optimize recovery increases over time, and that accelerating production rate causes the optimum co-production rate to increase even faster over time.
