Det Norske Oljeselskap: Total concluding appraisal well
BY DOMINIC CHOPPING
TRONDHEIM -- Det Norske said that Total E&P, as operator of production licence 535 in the Barents Sea, is in the process of concluding the drilling of appraisal well 7225/3-2 on the Norvarg gas discovery made in 2011.
The appraisal well encountered a thick gas interval with variable reservoir quality. However the reservoir productivity was somewhat lower than expected.
Two formation tests were carried out with a maximum production rate of 175,000 scmpd.
First assessment of the appraisal well results indicates that the resource range may have to be reduced on Norvarg, as compared to the initial evaluation from the discovery well.
Work will now be undertaken to analyze and interpret the data to further evaluate the estimated recoverable hydrocarbons on the structure and potential future development options. The well will be permanently plugged and abandoned.
The partners in the license are: Total E&P Operator 40% interest, North Energy 20%, Ithaca Petroleum 13%, Statoil 10%, Det norske 10% & Rocksource Exploration 7%.
