"This afternoon I assented to the bill amending the Deep Offshore (and Inland Basin Production Sharing Contract) Act," Buhari said in a statement on Twitter. "Nigeria will now receive its fair, rightful and equitable share of income from our own natural resources for the first time since 2003," he added. It is not clear whether the measure will take immediate effect or lead to discussions with oil companies to review their agreements, and Buhari's office has estimated the change will bring in at least $1.5 billion in added revenue annually by 2021. As oil prices have slid this year, meaning a drop in revenue to the government, Africa's largest oil producer has been steadily increasing pressure on the some of the world's biggest energy companies - Shell, Exxon Mobil, Chevron Eni, Total and CNOOC - who extract most of the crude oil in Nigeria.
