... injection into saline aquifers. A coupled thermohydromechanical flow model was used to mimic the injection and withdrawal of hydrogen. Potential locations for injection and monitoring wells are mapped. The primary focus of the analysis was to determine the temperature, pressure, strain and displacement...

... ABSTRACT: The knowledge of possible fracture formation and propagation in rock salt caverns is an important aspect for their safety-oriented design. During gas withdrawal the internal pressure is reduced and the associated cooling of the gas and thus also of the cavern wall cause a reduction...

...). The mechanical and chemical properties are relatively stable and are considered as an ideal medium for long-term underground storage of oil, natural gas, high-level radioactive nuclear waste (Chen et al., 2015) and compressed air (Li et al., 2003). brine withdrawal distillation flask erlenmeyer flask...

... formation pressure were inversed by using the formation rate analysis (FRA) method. The results indicated that the pumping modes have a great influence on the pressure response. The continuous withdrawal pumping mode produces the largest pressure drop, while the non-uniformly spaced withdrawal pumping mode...

... depends upon gas pressure, withdrawal rate and cavern size. Thermal tensile stresses, resulting from gas cooling, may generate fractures at the wall and roof of a salt cavern. However, thermal stresses do not penetrate deep into the rock mass. These fractures are perpendicular to the cavern wall...

... is disturbed by the withdrawal of subsurface fluids (e.g., Geertsma, 1966; Segall, 1989; Addis et al., 1998; Rudnicki, 1999). Probably the largest seismic events triggered by gas extraction are three major earthquakes (with magnitude M> 7) reported near the Gazli (Uzbekistan) gas field in 1976-1984 (e.g...

... ABSTRACT INTRODUCTION The effective stress in a hydrocarbon reservoir increases as a result of the decline in pore pressure associated with the withdrawal of fluids. Under such conditions, certain porous rocks experience a sudden increase in compressibility. The phenomenon that leads...
