Brine flood was carried out in a 7.12cm long and 3.81cm diameter core sample at different flow rates. The plot of flow rate (cc/s) versus differential pressure (atm) resulted in a straight line with slope of 1.37. (a) Determine the permeability of the core sample in mD. (b) If the experiment is repeated with oll, what would be the pressure difference between upstream and downstream in atm if oil is flooded at 5cc/s. Additional data: water viscosity =1.06cP, oll viscosity =3.42cP Brine flood was carried out in a 7.12cm long and 3.81cm diameter core sample at different flow rates.
