Abstract

Underground gas storage usually is used to assure stable supply during peak demand season of the year. With advances in gas storage at oil industry, optimization of storage reservoir performance and enhanced recovery is considered. In this paper, we focus on wells configuration optimization in an actual gas condensate reservoir. The injection/production well separation during underground gas storage leads to an increment in reservoir condensate recovery. The well separation reduces the number of wells that can be used either for injection or production. In addition to, the well separation reduces the produciblity of low permeability reservoirs, but because of high value of condensates and its minor effect on the produciblity of the reservoir with medium permeability, this approach is considered economical. The well configuration optimization and using horizontal wells in storage periods can increase the condensate recovery of the reservoir. Parameters which effect on well configuration optimization include: (1) water saturation, (2) injection/production well configuration and (3) reservoir permeability. As a production rate reaches to its specified value, and an optimized configuration in gas condensate reservoirs, production is maximized and the enhanced condensate recovery for remained fluid in the reservoir is achieved.
