The first hydraulic ,fracturing, of wells in Vietnam were successfully performed ,Offshore, in the Bach Ho (White Tiger) Oil Field. Near-tip-screenouts rather than tip-screenout treatments were performed. The goal of the project was to improve production from existing wells rather than drill new wells and reduce the cost per barrel produced.
