reservoirs to rock properties

1. [1 pt.] Brine flood in a 1.9in. long and 1.5in. diameter core plug from the North Sea resulted in a stabilized pressure drop of 46.05psi. The flood was carried out at 0.05mL/min with brine viscosity of 0.443cP. Determine the absolute permeability of this plug in millidarcies. 2. [1 pt.] The daily production from a certain oil well is 718.5 barrels. The drainage area is 160 acres where the average reservoir pressure is at 1850psi. If the oil viscosity is 2.2cP, wellbore radius is 0.5 ft, thickness of payzone is 16ft, and formation permeability is 180mD, what is the well flowing pressure? Note: 1 acre =43560ft2
