According to the revised estimate, gross volume of oil in place range from 0.9 to 1.9 billion barrels with a current expected value of 1.3 billion barrels. The gross recoverable oil reserves range between 150 million to 370 million barrels, with a current expected value of 230 million barrels.

DNO said that it revised the estimates based on the latest available data and the initial results from the reservoir modeling studies.

The company also said that the basis for these estimates is the current production capacity at the central processing facilities of 50,000 barrels of oil per day.

Helge Eide, president and managing director, said: We are pleased to note that this update more than doubles the estimated reserves in Tawke. The data gathered to date and technical work undertaken by the company has confirmed the high quality of the Tawke field.
