asked Her Majesty's Government:

Whether they will calculate the estimated proportion of total revenue from North Sea oil that could be defined as Scottish. [HL750]

The Government's figures for receipts from the UK's upstream oil and gas activity are calculated on the basis of all activity, both onshore and offshore, from the whole of the UK's continental shelf. They are not split down by geographical area and we are therefore unable to provide the breakdown that is requested. As there is no classification of oil and gas fields as English, Scottish or Welsh and there is no accepted view on what comprises “Scottish waters” it would not be possible to undertake such an exercise and the Government have not done so.
