The value of Scottish North Sea oil and gas has slumped by almost a quarter to reach the lowest total recorded since 1999, new figures have revealed.
Despite a 21.4% increase in oil and gas production in 2015-16, Scottish Government statistics showed provisional sales income fell by £4.1 billion to £13.4 billion.
That represents a drop of more than £10 billion from two years ago, with sales income in 2013-14 amounting to £23.8 billion and compares to a high point of £29.5 billion in 2008-09.
The drop in sales value is due to "sustained low prices" for oil and gas, the Scottish Government said, with prices having dropped to below 50 US dollars (£37) a barrel, compared to the high point in July 2008 of 147 dollars (£111).
Scotland produced an estimated 70 million tonnes of oil equivalent (mtoe) last year, up from 57.7 mtoe in 2014-15.
While oil and gas fields in Scotland accounted for almost all (96%) of the UK's crude oil and natural gas production, the volume produced is half the level it was in 2004-05 and well below the 184.6 mtoe recorded in 1999-00, the year that the statistics began.Read moretopics from
