... to investigate the confinement effect on the phase behavior of an 8- component reservoir fluid in a multi-scale (nano-scale + macro-scale) media. Two similar cubic boxes are utilized to simulate the macro-scale porous media while an extra gauge cell with fixed volume is added to the system to simulate the nano...

... Abstract The nanopore confinement plays an important role in fluid phase behavior and transport. However, investigation of the confinement effect on fluid phase behavior and production performance is lacking in the petroleum industry. Conventional models need to be adjusted to account...

... temperature, the bubble-point pressure of the Middle Bakken oil is reduced by 17.32% with consideration of the confinement effect. Such a significant suppression represents a late occurrence of the gas evaporation, which implies a potentially higher production of the shale oil reservoir. Compositional...

... Abstract Confinement effect of nano-pores in shale reservoirs causes the fluids behaving significantly different from bulk fluids. The unique structural and thermodynamic properties of the confined fluids, such as oscillatory density profile and critical property shift, disable the commonly...

... method is presented honoring the compositional variability in nanopores for an improved accuracy in predicting hydrocarbons in-place in presence of adsorption and nano-confinement effects. The method allows us to differentiate mobile bulk hydrocarbon fluids from the fluids under confinement effects...

..., it is theorized that the phase behavior, capillary pressure and relative permeability are influenced by confinement effects in small scale pores of nanometer size. The phase envelope in nanopores will shift to a point where many reservoir hydrocarbon mixtures are in supercritical state. Also, interfacial tension...

... reservoirs can be improved by increasing oil relative permeability and reducing oil viscosity. A CO 2 flooding can be a promising technique in improving tight oil recovery. There exist a large amount of nanoscale pores underground. Within such a confined system, the nanoscale pore confinement effect can...

... the hydrocarbon thermal-dynamic properties, resulting in a variation in phase equilibrium. It has been recorded in previous research work. However, there is no clear statement for the reason of the confinement effect on phase equilibrium, and the minimum pore size at which the confinement effect is strong...
