Characterization of a Non-Darcy Flow and Development of New Correlation of NON-Darcy Coefficient
Darcy’s law has long been used to describe the flow in porous media. Despite the progress that took place in oil production industry research, it became clear that there is a loss of pressure, especially in the area near the wellbore region, where Darcy ...
