Even on a gloomy morning, you can still see the supply boats waiting for crews to go offshore in line with their engines idling along Aberdeen’s waterfront. In its last act, it doesn’t appear to be an industry. However, if you speak with nearly anyone involved in UK energy policy today, the main point of contention is that data, not boats, is at issue.
Since the late 1960s, the North Sea has been producing gas and oil; production peaked in 1999. Production had dropped to about a fifth of its peak level by last year. Approximately 93% of the recoverable oil and gas in the basin has already been extracted, according to a startling statistic cited by critics. That statistic is technically correct and frequently used. What it omits is less memorable but more significant: an estimated 2.9 billion barrels of oil equivalent remain in reserves, with several billion more in contingent and potential resources. Whether that is “a lot” or “not much” seems to depend solely on who is speaking.
It seems that the argument is now more about which number sounds worse in a headline than it is about geology. According to a popular assertion, new drilling permits would provide “only 36 days of gas.” Industry voices argue that this misinterprets how a mature basin operates, arguing that ongoing investment is necessary only to slow the decline, as Norway has been able to replace a far larger portion of its production than Britain has in recent years. It’s a valid point, but it’s important to keep in mind that this is the kind of argument an industry trade association would make about itself.
The household bill question is more difficult to spin either way. This year, an Oxford study examined the financial implications for an average family of switching to renewable energy versus full North Sea exploitation. The difference is substantial. A household might save between £16 and £82 annually by extracting every last barrel from the basin and redistributing the tax revenue, but only for as long as extraction continues, which is likely to be another 20 years at most. Making the switch to renewable energy, especially when heating is fully electrified, could result in annual savings of £105 to £441, and those savings don’t end when a field runs dry.
At least based solely on the bills argument, that is a rather negative comparison for domestic drilling. North Sea production still supplies more than half of the UK’s oil and gas needs, so it’s not worthless. Moreover, cutting imports has its own benefits when international markets are unstable, as they were during the pandemic and again during tensions in the Middle East earlier this year. Although energy security and energy bills are often discussed together, it turns out that they are not exactly the same battle.
It’s difficult to ignore how frequently both sides strive for selective certainty as you watch this unfold. The oil isn’t gone, but it also isn’t limitless. Over time, renewable energy becomes more affordable, but the UK is still far from being electrified enough to realize these savings. Although Norway’s reserves and fiscal model differ from Britain’s, Norway is frequently used as an example. The North Sea isn’t a story with a neat conclusion; rather, it’s a slow, contentious wind-down that policymakers keep trying to pass off as a decisive decision. Perhaps this is the real lesson to be learned from all of this.
