Due to their complex pore-throat networks, low permeability, and high water saturation, water-bearing tight sandstone reservoirs exhibit pronounced heterogeneity in formation pressure distribution and unclear reserve mobilization patterns. These factors hinder accurate estimation of remaining gas and the design of ba...

The tight sandstone gas reservoir in Qingshimao gas field has the characteristics of complex gas–water distribution, low reservoir quality, low porosity, low permeability and high water saturation. Single-well productivity is low, the production and pressure decrease rapidly, the stable production period is short and e...

Geothermal energy extraction using existing wellbore systems provides a promising approach for sustainable heat utilization; however, the long-term thermo-hydro-mechanical (THM) responses associated with different working fluids remain insufficiently understood. In this study, a three-dimensional coupled THM model was...
