The 1931 Dogger Bank earthquake?
There is likely nothing there worth drilling or fracking.
Oil and gas do not exist everywhere. If they existed there they would already have been pursued.
And a little bit up the thread there is an announcement of new discovery in the North Sea. I read those articles. They’re talking about a few hundred million barrels of oil equivalent. This is nothing as oil fields go. A serious oil field is tens of billions of barrels. And as soon as you put the word equivalent in there you’re talking about gas more than oil which is less important and priced lower.
The way things like this happen is some wildcatter will perform what they claim is the seismic exploration and announce a discovery and make very clear they get paid to drill, they do not get paid to produce. So they will pitch the results of their study to people who make money from production and hope that that somebody will pay them to drill regardless of results.
This is the oil business. This is the way it has run for decades. As oil becomes more and more scarce you will find more and more of these charlatan types pitching their fake studies.
Dogger Bank is in the North Sea not in England. But never post without checking wikipedia, lesson learned.
