The lower limit pressure design is a critical aspect of underground gas storage, as it directly impacts key operational factors such as base gas volume and operating gas volume, as well as the economic benefits of the storage. This study analyzes the factors influencing the lower limit pressure, reviews extensive domestic and international literature, and summarizes the history and findings related to the design of the lower limit pressure. It also evaluates the advantages and disadvantages of different design approaches. In China, medium and deep gas storage are the primary types, with technical indicators such as working volume and peak load capacity being the main constraints, while considering project investment. In other countries, factors like the quantity of injection-production wells and compressor energy consumption are the primary controls. Artificial intelligence algorithms are used to assess the economic benefits and technical performance of gas storage operations. The findings suggest that despite the significant differences in geological conditions between domestic and international gas storage, the future direction of lower operational limit pressure development will focus on integrating technological and economic considerations.
