..., which improves the physical properties of the reservoir, and helps to improve the gas seepage and the capacity expansion. According to the characteristics of oil recovery and gas storage, the process of UGS operation can be divided into two stages, the cooperation stage and the gas storage stage...

... ABSTRACT Learning from the operation experience of built salt cavern gas storages is necessary for new cavity construction. Jintan Gas Storage is the first salt cavern underground gas storage in China and Asia. Since the pilot experiment in 2003, it has been put into operation for about 20...

... ABSTRACT Solution mining is the most critical process for salt cavern gas storage. So far Salt cavern gas storages in China are mainly single-well-cavity, and the time of dissolution between two and four years. Solution mining utilize intermediate hanging string and long hanging string...

... ABSTRACT: Depleted-reservoirs underground gas storage are playing an increasingly important role in seasonal demanding of natural gas, ensuring stable gas supply and strategic reserves. However, due to the physical properties of the reservoir, the problem of sand production in the wellbore...

... ABSTRACT: With the rapid development of the global economy and the adjustment of energy structure, the demand for underground salt cavern gas storage is particularly urgent. The technology of double-well cavity creation with small well spacing is a relatively novel construction method of salt...

... to measure the contributions of various swelled-clay-shrinking agents, agent concentrations and deposit meshes to free water content. The results showed that SA2# was the most suitable agent and the peak shrinkage was up to 30.02%, which is equivalent that the gas storage with 1.5 million m 3 can enlarge...

... ABSTRACT: The construction of underground gas storage is currently an important method for global natural gas storage and peak shaving. Underground salt cavern gas storage has the advantages of convenient cavity construction and low cost, and has become a type of gas storage with a wide range...

... ABSTRACT: In order to ease the supply pressure of natural gas caused by factors such as seasonal changes and urban development, underground gas storage is emerged. When the gas storage well is used as gas injection well, the injected gas will squeeze cement stone; when the gas storage well...

... ABSTRACT: The underground gas storage (UGS) is an efficient technology that became an indispensable link in the gas supply chain to respond to the needs of the market. Due to high gas production at Neuquén Province and low demand in spring and summer seasons, developing a UGS could be a very...

... ABSTRACT: The deformation stability and control theory based on viscoelastic, viscoplastic and viscodamage models is developed to simulate time-dependent deformation and quantitatively evaluate the long-term stability of gas storage caverns in salt rock. A quantitative criterion for the long...

... ABSTRACT: As an important supporting project of the “West-to-East Gas Pipeline project” of China, the construction of the underground gas storage (UGS) of salt cavern in Jintan is mainly to solve the problem of emergency gas supply. Due to the unbalanced gas supply caused by seasons, climate...

... ABSTRACT: In recent years, the geomechanical demand for the design of new gas storage caverns has changed significantly. Because relatively large temperature differences due to the operation of the caverns may occur, thermodynamic calculations of the gas temperature within a geomechanical...

... ABSTRACT : Reasonable operating pressure is the key to ensure the safe operation of salt cavern gas storage. The determination of upper and lower limit operating pressure is particularly important. Take into account the characteristics of a bedded salt mine, a set of methods is proposed...

... ABSTRACT: China has an urgent demand for natural gas storage because of the current bad situation of natural gas supply, consumption and storage. Based on the investigation of distribution and geology of salt mines, it is found that China has basic geological conditions and necessary brine...

... Abstract: Finite element analyses were performed to estimate axial deformation of cavern wells due to gas storage operations in solution-mined salt caverns. Caverns shrink over time due to salt creep and the cavern roof subsides potentially threatening well integrity. Cavern deformation...
