This paper gives a demonstration of environmental risk analysis and risk management by use of the CHARM (Chemical Hazard Assessment and Risk Management) model for making cost/environmental benefit evaluations of produced water handling. The BP operated Ula field in the North Sea is used as a demonstration case. The CHARM model is developed by Aquateam, Norway and TNO in the Netherlands on behalf of the oil operators, chemical suppliers, and environmental authorities in the North Sea countries. The CHARM model has been discussed and is accepted by the Oslo and Pans Commission (OSPAR). The environmental risk analysis demonstrated in this paper covers evaluation of the environmental impact of the produced water discharges, including chemicals and natural constituents from the Ula platform. The environmental risk analysis was performed for various environmental management options. Two options were claborated for comparison to a reference situation. The Ula produced water constituents demonstrated variable contributions lo the total environmental risk. The environmental risk was slightly reduced by improved water treatment, but the most significant reduction was seen for the option of produced water reinjection (PWRI) PWRI reduced.
