SINCE the Forties oil fields near Aberdeen produced its first barrels of oil in 1975, scores have followed in its wake.
As well as oil itself, numerous gas and condensate fields, a natural gas by-product in liquid form, have come into production in Scottish waters.
As part of our exclusive series investigating the impact of the McCrone Report (a secret government memorandum compiled 49 years ago by the Scotland Office) on energy policy, the cost-of-living crisis and a whole other host of issues affecting modern Scotland, we have put together a series of interactive graphs to set out the scale of production in the North Sea.
In total, 180 fields' first production have been logged by the North Sea Transition Authority (NSTA), the rebranded industry regulator Oil and Gas Authority (OGA), since 1975.
The first two oil fields, Forties and AUK, came online in 1975. Since then, a steady supply of fossil fuels has made its way out of Scottish waters.
How many of each kind of field have been brought into production?
As you can see from the graph above, by far there have been a significant number of oil fields that have successfully started production in the North Sea - 138.
Condensate fields come second with 34 logging their first production since 1975, compared to only eight gas fields.
How many oil fields were brought online each year?
NSTA data logs each individual field by the first date they produced either oil, gas or condensate, so for The National's analysis we had to combine the data into each year and by each product.
As you can see from the graph above, this revealed that 1996, the last year of the UK Conservative government under John Major, was when the highest amount of fields completed production for the first time in one year.
The second, 2017, was just a few years after Scotland voted No in the independence referendum.
How does this look over time?
Our interactive graph above shows the number of oil fields that produced their first fossil fuels each year from 1975 until 2022.
As NSTA do not give locations for these fields, except for grid references, we have also compiled them into a list below for ease.
