* North Sea: This is the primary source of oil and gas in the UK. The oil fields are located in the UK sector of the North Sea, extending from the east coast of Scotland to the north-east of England. Major oil fields in this area include Forties, Brent, and Buchan.
* Onshore: While much smaller in scale than the North Sea, there are also some onshore oil fields in the UK, mainly in:
* England: The Wytch Farm oil field in Dorset is the largest onshore oil field in the UK.
* Scotland: There are smaller onshore fields in the Moray Firth area.
It's important to note that oil production in the UK has been declining in recent years. While the North Sea remains a significant source of oil, production is expected to continue to decline in the future.
