Shell in Nigeria
In oil production, Nigeria is the most important country for Shell. During the period 2006-2010, Nigeria accounted for about 16% of Shell’s worldwide production of oil and liquid natural gas. During the year 2009, production falls due to disrupting activities by militant groups in the Niger Delta reached their peak for the time being. During the year 2010, production climbed back again, with Nigeria accounting for almost 19% of Shell’s worldwide production of oil and liquid natural gas.
