碩士 / 國立成功大學 / 資源工程學系 / 104 / The purpose of this study is to evaluate the performance of a produced water-drive gas reservoir in offshore Taiwan by reservoir simulation. The geological and numerical models for the C gas field case study were built and the history matching on the C gas field C-W block was performed. The major steps in the case study were: (1) gathering the geology, geophysics, PVT experiment, and production data, (2) studying the PVT behavior of a nature gas sample from the production well, and (3) history matching. The history matching was done via trial and error by modifying specific reservoir properties, performing end point scaling and modeling the aquifer support in the system.
After the history matching, a reliable numerical model was constructed. The reservoir simulation estimated that the Original Gas in Place was about 2,229 MMSCM and the gas recovery was 25%. Based on the distribution of remaining in-site gas, we propose a new production project for optimizing production from this water drive gas reservoir. Given the designed operation, the C gas field can be produced more 340 MMSCM of gas and predicted extra recovery is about 17%.
