A 6-inch well bore is drilled into a 50 md sand with re = 300 ft. The drilling mud penetrated the formation for a distance of 1.5 foot and reduced the permeability in this invaded zone to a value of 10% of the original.? i. Assume a perfectly circular drainage area, calculate the average permeability of thewell system. ii. Calculate the skin factor for this system iii. Calculate the equivalent wellbore radius due to the calculated skin factor assumingxw-0.33 ft A 6-inch well bore is drilled into a 50 md sand with re = 300 ft.
