Paper presented at the SPE Reservoir Characterisation and Simulation Conference and Exhibition, January 24–26, 2023
Paper Number: SPE-212695-MS
... Abstract Injecting CO 2 into the saline aquifer is considered to be an effective strategy to mitigate CO 2 emissions. Saline aquifers are known to have a wide range of salinities and several evidences showed that different brine salinities give rise to different CO 2 -brine-rock wetting...

... the phase equilibrium computation integrated with our model. It is of particular significance because the corresponding black oil simulation for CO 2 injection in saline aquifer could be performed on any commercial reservoir simulator in large scale to satisfy most of the requirements of CCS studies...

... environments were tested, including one case with variable WBM salinities across the logged MD interval without having any interference from any OBM during the drilling process. General conclusion is that less interval drilled with OBM pours into the benefit of obtaining higher data quality from WBM...

... interdependent complexity of dissolution and precipitation kinetics. In this study, a numerical approach is developed and implemented to analyze the effect of rock type, reservoir temperature, brine salinity on CO 2 mineral trapping in compositionally distinct subsurface carbonate reservoirs. Here, we...

... depends strongly on the salinity and temperature conditions. In order to optimize the surfactant injection procedure, the salinity and temperature effects are commonly studied through series of laboratory experiments. However, these types of experiments are often long and expensive. Therefore, engineers...

... of temperature (~ 250 F) and salinity (~ 200,000 ppm). Detailed screening study and performance review assessment have been conducted, in which gas and chemical based EOR technologies were identified for targeted reservoirs. The candidate reservoirs have a long history of EOR projects focusing on miscible...

Paper Number: SPE-175568-MS
... Abstract Laboratory studies have shown that wettability of carbonate rock can be altered to a less oil-wetting state by manipulation of brine composition and reduction of salinity. Our recent study (see Mahani et al. 2015b ) suggests that a surface-charge change is likely to be the driving...
