... previous literature, yielding an average error of 1.29%. Results indicate that the presence of nanopore confinement could decrease the density difference between the liquid and vapor phase of the quaternary mixture, and thus induce the reduction of interfacial tension (IFT). As pore size becomes smaller...

... assess the plugging behavior of the product solution across a range of pore sizes smaller than those which conduct in the rock sample. Coreflood injectivity tests revealed the onset of face plugging as a function of average polymer size. Co-solvent was shown to dramatically improve the transport...

.... It also showed that depending on fluid types, temperature, pressure and pore sizes, the fluid density profile would change. The pore size range we focused on was from 2 nm to 10 nm. In order to present the condensate system, a synthetic mixture of 75% methane and 25% n-butane is used. It is found...

... was destroyed quickly in the largest pores (<0.005 mm 3 ). In contrast, oil saturations rose much more gradually for the most common or intermediate-sized pores (around 10 −4 mm 3 , the peak in the pore size distribution). The minimum in oil saturation versus pore size may result from a balance between gel...

... the pore size. A water based gelant will flow in the water preferred pathways and block these channels. The largest DPR effect is observed in mixed wetting media where the difference between oil preferred and water preferred pathways is enhanced compared to homogeneous wetting media. The oil saturation...

...Methods Sample Selection. The cores came from several wells located in different parts of the field. These Permian aged limestones are wackestones and packestones. The pores are intergranular and intragranular with some of the matrix porosity enhanced by dissolution. Pore sizes were...
