Hit like the rest of the world by the Covid-19 pandemic with 97 confirmed cases, Nigeria over the weekend ordered oil and gas companies to reduce their offshore workforce and move to 28-day rotations (down from 14 days previously) as part of measures to curb the spread of the coronavirus. The government circular, addressed to the companies concerned, further specified that « non-essential personnel currently at offshore sites should be removed with immediate effect ». All these measures reflect the desire of the populous African country to protect its oil production as best it can, since black gold provides 90% of the country’s foreign exchange.
