"This work provides a lab experiment to describe the fluid diffusion in nanoscale porous media. By using ideal ceramic membranes which have uniform pore size in nanoscale and homogeneous pore distribution instead of shale or tight sandstone which have various pore sizes and complicated pore distribution and structure, a better understanding of fluid flow through nanoscale porous media could be gained.
Core flooding test were conducted by injecting nitrogen and water separately to describe gas and liquid flow in nanoscale porous media. With all the other factors known or controlled, pressure and flow rate were measured to calculate permeability. By the difference of the ability that gas and fluid pass through the different sizes of porous media, we can better understand how the nanoscale pore size in unconventional reservoirs affects the petroleum production.
Lab data were fitted into two derived models for fluid diffusion in nano-scale porous media by Javadpour and Florence. Lab data made a good fit with Javadpour's model except a slight difference of slope with a reasonable tangential momentum accommodation coefficient. However, permeability results getting from Florence's model were in different magnitude from lab data which might owing to high Knudsen number due to the extra small pore size in this lab"--Abstract, page iii.
