Claimed by The Economist that break even for a barrel in the UK is 60$ is pure nonsense, and Nigeria 65-68 is rediculous unless it icludes several other factors like eg. tax.
Back in 98-99 the price was around 10-14$/barrel still everybody working in the branch were earning well.
Could be slightly higher than 7-9 but we are not even close to 20$ in the NS.
