Therefore some modifications of TOUGH2, Version 2 and of the EWASG module are needed before an application on halite formation in aquifer gas storage. This work is focused on the modifications performed on TOUGH2, Version 2 to model the halite formation
To illustrate the halite scale formation in the porous medium, an SEM picture (Kleinitz and Tölcke, 1982) of a formation rock with salt deposits in a pore channel is shown in Figure 1. The presence of halite scale on the internal surface of the pore and the associated constriction of the cross-sectional area, with the resulting impairment in

Gas hydrate formation is a serious problem in the oil and gas industry, since its formation can plug wells and prevent production. The gas hydrate is a crystalline solid with a natural gas molecule surrounded by a cage of water molecules. It forms at high pressures and low temperatures. This is a problem for offshore gas wells, where the temperature is low in
2016年10月24日The formation of anhydrite and halite scale, which has been observed, was predicted only for the most saline samples. Finally, in addition, the formation of anhydrite and/or halite may be related to the localized conditions of increased salinity as water is partitioned into the gas phase during production.
