Flow unit 4 is macroporous but wet (S<sub>w</sub> = 100%); this indicates an oil-water contact. Flow unit 3 is macroporous and has intermediate water saturation (S<sub>w</sub> = 70%). This looks like a transition zone. Flow units 2 and 1 are mesoporous and are at immobile water saturation (S<sub>w</sub> = 45%). This is verified by the well testing about 100 bo/d and 300 Mcfg/d (16 m<sup>3</sup> oil and 8,500 m<sup>3</sup>gas per day) with no water from perforations in these flow units and by a bulk-volume-water plot following. This lack of water production is remarkable, considering that the well lies only about [[length::25 ft]] (7 m) above the [[free water level]].
