Evaluation of Water-Sealed Gas Reserves and Identification of the Development Potential in an Unconsolidated Sandstone Reservoir with Edge Water: A Case Study of Layer Group II-2 in the Sebei-2 Gas Field
Water invasion can isolate gas and reduce gas-phase mobility in unconsolidated sandstone reservoirs, complicating reserve evaluation and target selection. This study evaluates dynamic reserves and remaining gas potential in the II-2 layer group of the Sebei-2 Gas Field by combining classified well-level reserve estimat...
