This paper presents the cost optimization of underground gas storage (UGS), designed from lined rock caverns (LRC). The optimization is performed by the non-linear programming (NLP) approach in different rock environments. For this purpose, the NLP optimization model OPTUGS was developed. The model comprises the cost objective function, which is subjected to geomechanical and design constraints. The optimization proposed is to be performed for the phase of the conceptual design. A numerical example at the end of the paper demonstrates the efficiency of the introduced optimization approach.
