The permeability of 160-acre formation drained by a single well is 15mD. The well is heavily acidized to a permeability of 250 mD and a radius of 30 ft, and then completed. During well completion a 2 ft thick damaged zone developed in the vicinity of the wellbore. The permeability of this damaged segment is 4 mD. The wellbore radius is 0.5ft. Calculate the average permeability of this drainage area
