Environmental Risk Assessment of Exploration Drilling in Nordland VI

DNV has, on assignment from Norsk olje og gass, conducted an environmental risk analysis for a hypothetical exploration drilling  operation in Nordland VI. The analysis has been conducted for a “base case” which has been developed using conventional analysis methodology and for an “alternative case” which takes into account risk reducing measures. In cooperation with drilling and well integrity experts DNV has conducted an evaluation of various risk mitigating measures including new
technological solutions and operational improvements. The aim of the evaluation has been to illustrate to which extent recent improvements in the drilling industry have contributed to risk reduction. The results clearly demonstrate that significant risk reduction may be achieved when taking into account the recent improvements in the industry, compared purely basing the risk analysis on the historic data.
