UK-Norwegian treaty on Statfjord

This regulated production from the field across the boundary between the two countries in the North Sea, and followed by and large the same pattern as the treaty on joint exploitation of the Frigg reservoir, signed three years earlier.Reserves in the Statfjord reservoirs were divided between 84.09322 per cent for Norway and 15.90678 per cent for the UK. Pursuant to the unitisation agreement between the licensees, this division could be adjusted if new information warranted that. It was specified with great accuracy since even the fifth decimal place could mean a big difference in revenues over a long period.
