Folorunsho Alakija surpasses Opra Winfrey as the Richst Balck woman in the world

A new feature dubbed, Africa’s secret millionaires has announced that Nigerian billionaire Mrs Folorunsho Alakija is the richest black woman in the world. In a post yesterday, www.ventures-africa.com is quoted saying: “Folorunsho Alakija, a Nigerian billionaire oil tycoon, Fashion designer and philanthropist who is worth at least $3.3 billion- contrary to a recent Forbes Magazine ranking which pegs her net worth at only $600 million.”
The publication cited Alakija’s 60 percent stake in OML 127, using comparators to justify its argument. According to Ventures Africa “In July 2012, Royal Dutch Shell agreed to sell its 45 percent stake in OML 30 for $850 million to Heritage Oil and Shoreline Energy.
According to Fool.co.uk, OML 30 currently produces 35,000 barrels of oil per day.
So, if 45 percent of a 35,000 bpd-producing oil bloc is $850 million, 100 percent of the same bloc = $1.88 billion i.e 100/45 x $850 million
If a 100 percent stake in a 35,000 bpd-producing oil bloc is $1.88 billion, by the same logic, a 100 percent stake in 200,000 bpd-producing oil bloc is worth $10.74 billion i.e 200,000 bpd/35,000 bpd X $1.88 billion
Folorunsho Alakija’s 60 percent stake in a $10.74 billion oil well is worth $6.44 billion.
Technically, her 60 percent stake in OML 127 is worth $6.44 billion.
