| Abstract | The hydrocarbon resources we have at subsurface are limited and hence top priority has always been to get maximum out of it. Many times perforation strategy has been done based on experience, and we have never had a chance to check if other perforation strategies will be able to deliver a better result. In this study, reservoir models are built using Integrated Production Modeling (IPM) suite. Then, different strategies are applied to the same well in order to determine the strategy that delivers the highest recovery. The aim of this study is to investigate the impact of different drive mechanisms and various perforation strategies on recovery factor (RF) for multilayered gas reservoirs. The reservoirs for this study are dry gas reservoirs in the Gulf of Thailand (GoT).There are 3 cases in this study: (1) all reservoirs are depletion-drive gas reservoirs, (2) all reservoirs are water-drive gas reservoirs and (3) two reservoirs are depletion-drive and another two reservoirs are water-drive. Based on this study, the cumulative gas productions for different strategies are not much different for depletion-drive gas reservoirs. However, for water-drive gas reservoirs and combination-drive gas reservoirs, bottom-up perforation together with shutting off depleted zone and water producing zone provides better gas recovery. |
