Nigeria is the 12th largest producer of petroleum in the world, the 8th largest exporter, and has the 10th largest proven reserves. Petroleum plays a large role in the Nigerian economy, accounting for 40% of GDP and 80% of government earnings. However, agitation for better resource control in the Niger Delta, its main oil-producing region, has led to disruptions in oil production and prevents the country from exporting at 100% capacity.
