This research constructs a roadmap on asphaltene instability conditions using data...

... slightly increases. As the water-salt concentration increases, it compresses and destabilizes the double-layer surrounding the coal surface, causing a reduction in the absolute zeta potential value and making the coal surface more hydrophobic. The temperature has a negative effect on CO 2 wettability...

The additive combinations and concentrations were varied alongside important process conditions such as temperature...

... that the concentration of the impurities should be controlled in a rational range for the perspective of the economy and efficiency. The results show that the solubility of CO 2 is higher than N 2 and O 2 in the saline water, and close to that of SO 2 . We applied the solubility data to the numerical simulation...

..., and the bicarbonate-based electrolyte solution are prepared for the sensor's preparation. The assembled sensor was tested in aqueous solution with different CO 2 concentrations. Then the sensor was settled in harsh, high-pressure environments, in order to invest the performance of the CO 2 sensor under reservoir...
