November 19, Dagang oilfield geological technical staff after three plants were analyzed. 22 downhole hydraulic pump to restore production to date, 20.3 tons of oil a day eventually good results.
      22 wells located in the western belt Date Date hole near Block 55 wells. 1983 liquid and 333 tons of oil a day in the middle of pack, and then plugging that has no value.
