Total SA has drilled a pair of disappointing dusters in deepwater Nigeria. The first was the Oko-1 well on OPL 221, the first well on the block, which the French firm won in a closed bidding round in 2003. The block lies in water depths ranging between 200 and 1,000 meters. The second duster was the Ukot South, drilled on neighboring OPL 222 in Ukot Field.
