... this objective, a real-field geological model of a depleted sandstone gas reservoir with a shale cap rock was employed. The Peng Robinson equation of state as well as the viscosity and solubility models were tuned using published hydrogen properties. Recent relative permeability, capillary pressure...

... that the inverse of the oil and brine solubilities in the three-phase region should be linear with all formulation variables. This key result, which is used in this paper, is derived in part from the dimensionless form of the HLD-NAC equations that they developed. Abstract A successful surfactant flood...

... climate change. Accurate prediction of CO 2 solubility in brine is necessary for a better estimate of CO 2 storage capacity in subsurface reservoirs. Specific Equation of State (EOS) models coupled in compositional reservoir simulators are usually used to predict the fate of dissolved CO 2 over time...

... 2 solubility in the presence of H 2 S, these results were further compared to the CO 2 solubility profile measured for CO 2 in brine (without the introduction of H 2 S). It was observed that CO 2 solubility calculated for the CO 2 - H 2 S-brine system was reduced by approximately 15% compared...

... Abstract The chemical flooding is one of the major enhanced oil recovery (EOR) methods for recovering residual oil within the pores of rock. However, the injected chemical such as surfactant must be soluble in low and high salinity brine, compatible with reservoir ions, and stable at elevated...
